The success of VXI as an open, multivendor platform is a testament to the value of multivendor standards, and has made VXI the platform of election for open instrumentation systems.

    VXI is used in many different applications ranging from test and measurement and ATE, to data acquisition and analysis in both research and industrial automation. Although some VXI systems today are purely VXI, many users are migrating to VXI by integrating it into existing systems consisting of GPIB instruments, VME cards, or plug-in data acquisition (DAQ) boards. You can control a VXI system with a remote general-purpose computer using the high-speed Multisystem eXtension Interface (MXI) bus interface or GPIB. You can also embed a computer into a VXI chassis and control the system directly. Whatever your system configuration needs may be, VXI offers the flexibility and performance to remove on today’s most challenging applications.

    The exigency for VXIbus

    The claim for an industry-standard instrument-on-a-card architecture has been driven by the exigency for physical size reduction of rack-and-stack instrumentation systems, tighter timing and synchronization between multiple instruments, and faster transfer rates than the 1 Mb/s rate of the 8-bit GPIB. The modular configuration factor, towering bandwidth, and commercial success of the VMEbus made it particularly attractive as an instrumentation platform. The tremendous popularity of GPIB also made it attractive as a model for device communication and instrument control protocols. The VXIbus specification adds the standards necessary to combine the VMEbus with GPIB to create a new, modular instrumentation platform that can meet the needs of future instrumentation applications.

    VXI brings the following benefits to instrumentation users:

  • Open, multivendor standards maximize flexibility and minimize obsolescence
  • Increased system throughput reduces test time and/or increases capabilities
  • Smaller size and higher density reduce floor space, enhance mobility or portability, and give immediate proximity to device(s) being tested or controlled
  • More precise timing and synchronization help measurement capability
  • Standardized VXIplug&play software eases system configuration, programming, and integration
  • Modular, rugged design improves reliability, increases stand for time between failure (MTBF), and decreases stand for time to repair (MTTR)
  • The Value of Open Industry Standards

    The baseline VXI hardware specifications are a mandate for interoperatibility between hardware products from different vendors. These specifications cover mechanical and environmental requirements such as module sizes, mainframe and module cooling, and EMC compatibility between modules, as well as automated system initialization and backplane communication protocols. The VXIplug&play Systems Alliance builds on these baseline specifications to address the system as a all with the goal of having the user up and running in “five minutes or less.” structure a system based on open industry standards means that you select components for your system based on your requirements, regardless of vendor. Open standards also ensure that once your system is built, your investment will continue to pay dividends well into the future.

    Both the VXIbus Consortium and the VXIplug&play Systems Alliance remain strong, active organizations committed to maintaining VXI as an open, multivendor technology and increasing its ease of disburse and end-user success. In fact, many of the largest instrument suppliers in the world are members of both organizations, including National Instruments, GenRad, Hewlett-Packard, Racal Instruments, and Tektronix. With VXIplug&play, you are assured that components from different vendors travail reliably in the very system. Members of the VXIbus Consortium and the VXIplug&play Systems Alliance believe combined their expertise to develop technically sound standards for both hardware and software, bringing the entire industry into a unique generation of instrumentation – a generation that stresses ease of disburse and open systems without sacrificing flexibility or performance.

    VXIbus Mechanical Configuration

    Physically, a VXIbus system consists of a mainframe chassis that has the physical mounting and backplane connections for plug-in modules, as shown in motif 1. The VXIbus uses the industry-standard IEEE-1014 VMEbus as a ground architecture to build upon. As shown in motif 2, VXI uses the full 32-bit VME architecture, but adds two board sizes and one connector. The P1 connector and the center row of the P2 connector are retained exactly as defined by the VME specification. The VME user-definable pins on the P2 connector and the additional pins on P3, the third VXI connector, implement instrumentation signals between plug-in modules directly on the backplane.

    The VXIbus specification includes packaging requirements, electromagnetic compatibility, power distribution, cooling, and airflow for VXIbus mainframes and plug-in modules. The modules are installed in the mainframe slots. LEDs, switches, test points, and I/O connections are accessible from the module front panel.

    Module and Mainframe Cooling

    Airflow direction is from bottom (P3) to top (P1). Cooling requirements must exist established for any modules and included in product specifications. These requirements must involve an operating point of minimum airflow requirement. Mainframe suppliers must also provide similar information for their mainframes.

    EMC and Noise

    The addition of a unique module to a VXIbus system must not demean the performance of any other module. The VXIbus specification includes near-field radiation and susceptibility requirements, which forestall one module from interfering with the operation of other modules. To back meet these requirements, the VXIbus module width was increased from the 0.8 in. VME requirement to 1.2 in., so that there is enough scope for the module to exist completely enclosed in a metal case for shielding. The metal cases connect to backplane grounds. Thus, you can disburse existing VME boards in a VXIbus chassis, but not vice versa.

    The VXIbus specification also has conducted-emissions and susceptibility requirements, which forestall any power supply din from affecting the performance of a module. For far-field radiated emissions such as FCC and VDE, each module must not contribute more than its participate of the total. For example, in a mainframe that holds 13 modules, each module must not contribute more than 1/13 of the allowed total. Because of the want for extremely precise time coupling between modules using the backplane, it is necessary to minimize the din and crosstalk on the backplane clock and trigger signal lines. The backplane is required to exist a single, monolithic board across any one slot. The VXIbus specification has a tutorial section on how to design a backplane for low din and towering signal integrity.

    Hardware Registers

    VXI modules must believe a specific set of registers located at specific addresses, as shown in motif 3. The upper 16 KB of the 64 KB A16 address space are reserved for VXIbus devices. Each VXI device has an 8-bit logical address that specifies where its registers are located in this address space. A single VXI system can believe up to 256 VXI devices. The logical address of a VXI device, which can exist manually set or automatically configured by the system at startup, is analogous to the GPIB address of a GPIB device.

    Register-Based Devices

    Because of the VXI configuration registers, which are required for any VXI devices, the system can identify each VXI device, its type, model and manufacturer, address space, and remembrance requirements. VXIbus devices with only this minimum flat of capability are called Register-Based devices. With this common set of configuration registers, the centralized Resource Manager (RM), essentially a software module, can fulfill automatic system and remembrance configuration when the system is initialized.

    Message-Based Communication

    In addition to Register-Based devices, the VXIbus specification also defines Message-Based devices, which are required to believe communication registers and configuration registers. any Message-Based VXIbus devices, regardless of the manufacturer, can communicate at a minimum flat using the VXI-specified Word Serial Protocol. When minimum communication is possible, higher-performance communication channels, such as shared-memory channels, can exist established to remove advantage of the VXIbus bandwidth capabilities.

    Word Serial Protocol

    The VXIbus Word Serial Protocol is functionally very similar to the IEEE-488 protocol, which transfers data messages to and from devices one byte (or word) at a time. Thus, VXI Message-Based devices communicate in a mode very similar to IEEE-488 instruments. In general, Message-Based devices typically hold some flat of local intelligence that uses or requires a towering flat of communication.

    All VXI Message-Based devices are required to disburse the Word Serial Protocol to communicate in a standard way. The protocol is called word serial, because if you want to communicate with a Message-Based device, you finish so by writing and reading 16-bit words one at a time to and from the Data In (write Data Low) and Data Out (read Data Low) hardware registers located on the device itself. Word Serial communication is paced by the bits in the response register of the device, indicating whether the Data In register is blank and whether the Data Out register is full. This operation is very similar to Universal Asynchronous Receiver Transmitter (UART) on a serial port.

    Commander/Servant Hierarchies

    The VXIbus defines a Commander/Servant communication protocol so you can construct hierarchical systems using conceptual layers of VXI devices. This structure is enjoy an inverted tree. A Commander is any device in the hierarchy with one or more associated lower-level devices, or Servants. A Servant is any device in the subtree of a Commander. A device can exist both a Commander and a Servant in a multiple-level hierarchy.

    A Commander has exclusive control of the communication and configuration registers of its immediate Servants (one or more). Any VXI module has one and only one Commander. Commanders communicate with Servants through the communication registers of the Servants using the Word Serial Protocol if the Servant is a Message-Based device, or by device-specific register manipulation if the Servant is a Register-Based device. Servants communicate with their Commander by responding to the Word Serial commands and queries from their Commander through the Word Serial protocol if they are Message-Based, or by device-specific register status if they are Register-Based.

    Interrupts and Asynchronous Events

    Servants can communicate asynchronous status and events to their Commander through hardware interrupts or by writing specific messages (signals) directly to their Commander's hardware Signal Register. Nonbusmaster devices always transmit such information via interrupts, whereas devices that believe busmaster capability can either disburse interrupts or ship signals. Some Commanders can receive signals only, whereas others might exist only interrupt handlers.

    The VXIbus specification contains defined Word Serial commands so that a Commander can understand the capabilities of its Message-Based Servants and configure them to generate interrupts or signals in a particular way. For example, a Commander can instruct its Servants to disburse a particular interrupt line, to ship signals rather than generate interrupts, or configure the reporting of only positive status or mistake conditions.

    Although the Word Serial Protocol is reserved for Commander/Servant communications, peer-to-peer communication between two VXI devices can exist established through a specified shared-memory protocol or by simply writing specific messages directly to the signal register of the device. Slot 0 and the Resource Manager

    The leftmost slot of a VXI chassis has special system resources such as backplane clocks, configuration signals, and synchronization (trigger) signals and therefore must exist occupied by a device with VXI “Slot 0” capabilities. The VXI Resource Manager (RM) function, essentially a software module, can reside on any VXI module or even on an external computer. The RM, in combination with the Slot 0 device, identifies each device in the system, assigns logical addresses, remembrance configurations, and establishes Commander/Servant hierarchies using the Word Serial Protocol to grant Servants to the Commanders in the system. After establishing the Commander/Servant hierarchy, the RM issues the begin habitual Operation Word Serial command to any top-level Commanders. During habitual system operation, the RM may also halt the system and/or remap the hierarchy if necessary.

    Three Ways to Control a VXI System

    System configuration is divided into three categories. The first character of VXI system consists of a VXI mainframe linked to an external controller via the GPIB. The controller talks across the GPIB to a GPIB-VXI interface module installed inside the VXI mainframe. The GPIB-VXI interface transparently translates the GPIB protocol to and from the VXI Word Serial protocol.

    The second configuration involves a VXI-based embedded computer. The embedded computer is a VXI module that resides inside the VXI mainframe and connects directly to the VXI backplane. This configuration offers the smallest physical size for a VXI system as well as performance benefits due to direct connection to the VXI backplane.

    The third configuration uses a high-speed MXIbus link from an external computer to control the VXI backplane. The external computer operates as though it is embedded directly inside the VXI mainframe. This configuration is functionally equivalent to the embedded method, except that it has the flexibility for disburse with a wide variety of computers and workstations.

    VXI Bus Interface Software

    One of the most principal considerations when selecting a VXI system is software. Software is the key to developing successful systems based on the VXIbus. There are many programming languages, operating systems, and application development environments (ADE) to select from when structure a VXI system. It is principal to originate the prerogative decisions to realize any of the advantages that VXI has to offer, while minimizing your development costs now and in the future.

    Your software decisions not only move overall system performance and system capability, but also development time and productivity. You should select tools that believe complete debugging capability and that travail with the most Popular operating systems and programming languages. If you select to program your VXI system using a standard language such as C, C++, Basic, ADA, or ATLAS, you should realize that standard programming languages finish not advance with built-in VXI capability. Rather, VXI capability is added through a VXI bus interface software library. This software component is very important, because it affects the election of VXI computer hardware, operating system, programming language, and ADE.

    Industry-Wide Software Standards

    As a step toward industry-wide software compatibility, the VXIplug&play alliance developed one specification for I/O software – the Virtual Instrument Software Architecture (VISA). The VISA specification, VPP-4.1, defines a next-generation I/O software standard not only for VXI, but also for GPIB and serial interfaces. With the VISA standard endorsed by more than 50 of the largest instrumentation companies in the industry including Tektronix, Hewlett-Packard, and National Instruments, VISA unifies the industry by facilitating the development of interoperable and reusable software components able to stand the test of time. Before VISA, there were many different commercial implementations of I/O software for VXI, GPIB, and serial interfaces; however, not anyone of these I/O software products were standardized or interoperable.

    The VISA standard lays the foundation and provides a unified migration path for industry-wide software compatibility. One of the most notable benefits of VISA is its capacity to significantly reduce the time and distress involved in programming different I/O interfaces. Instead of using a different API devoted to each interface bus, you can disburse the VISA API regardless of whether your system is controlled by GPIB, VXI, or a GPIB-VXI.

    With the vast number of choices in instrumentation and software now available, most users finish not want to exist locked into a specific vendor for their systems. Instead, they would prefer the license to select the best instruments and software available from multiple vendors and believe it any travail together with minimal effort. The IEEE 488.1 and IEEE 488.2 standards (for GPIB) and the IEEE 1155 standard (for VXI) ensured that the hardware would exist interoperable, but this approach was not taken for the software. Therefore, the exemplar unique driver architecture should exist a standard adopted by as many of the major vendors as possible. Then you could exist assured that any code written for your instrument is portable across controller vendors as well as operating systems. This is exactly what the VXIplug&play Systems Alliance has done with VISA.

    MXI Tutorial

    This section contains an overall introduction to MXI.

    MXIbus Overview

    The MXIbus is a powerful, high-speed communication link that interconnects devices using a springy cabling scheme. Derived from the VMEbus, MXI provides a high-performance pass of controlling VXI systems using commercially available desktop computers and workstations. National Instruments developed and published the MXI specification and released it as an open industry standard in 1989. In 1995, National Instruments introduced MXI-2, which offers even higher performance.

    An MXIbus system configuration combines the performance benefits of a custom embedded VXI computer with the flexibility and availability of general-purpose computers. The MXIbus system configuration uses the high-speed MXIbus cable to connect an external computer directly to the VXI backplane. With the MXIbus, you can locate the computer directly next to the VXI mainframe, or up to 20 meters away. Using the MXIbus, you can easily add other VXI mainframes, and disburse the plug-in slots in the external computer for GPIB-control, plug-in DAQ boards, or other peripheral adapter cards.

    For instrument control, MXI complements high-speed platforms such as PCI by harnessing their high-throughput potential. PCI-based desktop PCs compete with the most advanced computer workstations to provide a low-cost platform that delivers superior performance. You can disburse low-cost desktop computers to control sophisticated VXI instrumentation without sacrificing performance or control. More importantly, as unique desktop computers incorporate the latest technology including faster, more capable microprocessors and RAM, you can easily upgrade your VXI system as these newer and faster computers emerge to immediately gather increased VXI performance gains. Thus, a PCI-based MXI-2 solution such as their VXI-PCI8000 gives you excellent performance now with headroom for the future.

    A unique Generation of VXI Connectivity

    Many VXI users migrate from GPIB-based systems. As a result, the National InstrumentsGPIB-VXI is a Popular pass to control VXI instruments from a GPIB controller. An increasingly Popular pass to control VXI, however, is to disburse a custom VXI computer that plugs directly into the VXI mainframe, such as the National Instruments VXIpc™ and VXIcpu™ sequence of embedded VXI computers. This embedded approach is technically attractive because the computer communicates directly with the VXIbus and is tightly coupled to the instruments.

    Although an embedded computer is very powerful, custom VXI computers cannot possibly hold pace with the general-purpose computer market. In the final decade, specialized instrument controllers believe rapidly declined. General-purpose PCs and workstations, with their vast array of software and accessories, believe revolutionized the industry. By using general-purpose computers, the instrumentation industry directly benefits from the billions of R&D dollars spent each year in the general computer market.

    Most VXI users would prefer to disburse an industry-standard computer provided by a computer vendor rather than a VXI-specific computer provided by an instrument vendor. In fact, for VXI to truly become the platform for the next millennium, it must align itself with the powerful general computer market. Then VXI can remove advantage of the billions of dollars being spent and bring this investment to tolerate on the needs of the instrumentation community. VXI must exist able to remove full advantage of industry-standard PCs with PCI, EISA, and ISA, as well as workstations from Sun, HP, and others. VXI also must believe a transparent mechanism for extending to multiple mainframes, and a pass to accommodate instruments that cannot physically appropriate on a VXI module. MXIbus meets each of these needs.

     The exigency for MXIbus

    Today’s market demands that you add value to test and measurement systems. You exigency modular testing systems that can evolve with technological innovations in the industry. You want increased data throughput and the utmost in computing power; you want flexible, high-speed connectivity between multiple VXI/VME mainframes; and you want to exist able to hold up with innovations in PC and workstation technology. Today, sophisticated I/O architectures such as PCI are accelerating data throughput – who knows what tomorrow may hold. How can you remove these benefits both now and in the future? The respond is MXI.

    MXI provides you with a solution that combines the performance benefits of an embedded VXI computer with the flexibility of a general-purpose desktop computer. Their VXI-PCI8000 controller and their next generation MXI-2 provides you with an ultra high-performance VXI connectivity solution that can meet your needs both today and well into the future. Although traditional connectivity solutions believe proved to exist very effective, they also believe proved to exist the bottleneck in VXI test systems because the software protocol overhead associated with these methods significantly reduced the achievable throughput on the link. Using MXI, this bottleneck is eliminated altogether because MXI devices are connected at the hardware flat by mapping each physically separate system into a shared remembrance space. Physically separate devices transparently participate resources through simple reads and writes to the usurp address in memory. Their next generation MXI-2 products enhance VXI connectivity by defining a single memory-mapped backplane-on-a-bus that can transparently extend bus-level I/O, VXI triggering, interrupts, and systems clocks between systems. You can now disburse a single cable to conveniently participate trigger and timing information between mainframes in a multiple mainframe configuration. The MXI 2.0 specification also defines a synchronous data transfer fashion that increases MXIbus throughput for obstruct data transfers. From a system standpoint, this means that MXI throughput rates can easily hold up with the data rates of high-performance computers, peripherals, and instrumentation . From a user standpoint, this translates to increased performance and reduced time to test. By choosing a PC-based MXI approach, you are choosing to add value to your VXI instrumentation systems by using technologies that originate sense from both a cost and performance perspective.

    MXIbus Applications

    You can disburse MXIbus for a variety of applications. You can interface industry-standard desktop computers to VXIbus or VMEbus; you can create multiple chassis configurations using their VXI-MXI or VME-MXI extenders; and you can integrate VXI and VME chassis into the very test system.

    Figures 5 and 6 show two common configurations with MXIbus.

    How Does MXIbus Work?

    MXIbus is a general purpose, 32-bit multimaster system bus on a cable. MXI interconnects multiple devices using a springy cabling fashion similar to GPIB, but uses a hardware memory-mapped communication scheme that eliminates the software overhead. MXI devices can directly access each other’s resources by performing simple read and writes to usurp address locations. The unique MXI-2 standard expands on the MXI-1 standard by exporting any VXI backplane signals such as VXI-defined trigger lines, interrupt lines and system clocks, in addition to the standard MXIbus signals directly to the cabled bus. MXI-2 users can accomplish captious timing and synchronization tasks between up to eight, daisy-chained MXI devices.

    MXI device connectivity is accomplished at the hardware level. The MXI cable serves as a transparent link that interconnects multiple MXI devices. These devices are interlaced by mapping together portions of their individual address spaces so that a system composed of multiple devices behaves as a single system with a shared address space. motif 7 shows the MXIbus hardware memory-mapped communication. The immediate profit of this approach is increased data throughput due to the absence of software overhead.

    Each MXIbus hardware interface has address window circuitry that detects internal (local) bus cycles that map out to the MXIbus. In addition, this circuitry also detects external (remote) MXIbus cycles of connected devices whose addresses map into the shared remembrance space of the overall system. When a hardware write or read occurs with an address that maps across MXI, the MXI hardware interlocks the bus cycle between the devices via the MXIbus. This hardware scheme is the very as that used by embedded VXI controllers.

    MXIbus signals involve 32 multiplexed address and data lines with parity, address modifiers for multiple address spaces, single-level multimaster prioritized bus arbitration, a single interrupt line, a bus mistake line for handling timeouts and deadlock conditions, and handshake lines for asynchronous operation. Data transfers of 8, 16, and 32 bits are possible, as well as invisible read/write operations and integrated block-mode transfers. With synchronous MXI, the MXI-2 product line can achieve burst data rates as towering as 33 Mb/s, and sustained throughput rates exceeding 20 Mb/s, regardless of the length of the MXI-2 cable

    MXIbus Cables

    A single MXI cable can exist any length up to 20 m. Up to eight MXI devices can exist daisy chained on a single MXI cable length. If multiple MXI devices are daisy chained together, the total cable distance must exist no more than 20 m. The MXI-1 cable is a flexible, round cable similar to a GPIB cable (about 0.6 in. in diameter). Internally there are 48 single-ended, twisted-pair signal lines. MXI-2 features an improved cabling scheme that uses a single double-shielded cable between any devices, and a single high-density, high-reliability 144-pin connector per device. In this fashion, any MXI-2 devices participate not only the MXIbus itself, but also the VXI-defined trigger lines, interrupt lines, systems clocks, and other signals that were available on MXI-1 products as an optional second connector and cable (INTX). MXI-1 products disburse an MXI-1 cable between devices, and an optional INTX cable to participate trigger/timing information between mainframes in a multiple mainframe configuration. MXI-2 eliminates the exigency for an additional INTX cable in your system. Because of the cable differences, you cannot mix MXI-1 and MXI-2 products in the very system. Both MXI-1 and MXI-2 disburse double shielding with an aluminum mylar shield as well as a copper braid shield to eliminate any EMI problems, and both cables meet the National Electric Code (NEC) CL2 fire safety code. The stacking depth of two daisy-chained MXI cables is approximately 3.3 in.

    MXI is essentially a backplane bus in a cable. Each MXI signal line is twisted with its own ground line. any MXI signal lines are matched impedance to minimize signal skew and reflections. Stub lengths no more than 4 in. off the mainline interconnection minimize reflections due to impedance discontinuities. Termination networks, configured with onboard jumpers, are located at the first and final MXI devices to minimize reflections at the ends of cables.

    MXI uses state-of-the-art, single-ended, trapezoidal bus transceivers to reduce din crosstalk in the transmission system. Designed specifically for driving backplane bus signals, these transceivers believe open-collector drivers that generate precise trapezoidal waveforms with typical rise and Fall times of 9 ns. The trapezoidal shape, due to the constant rise and Fall times, reduces din coupling (crosstalk) on adjacent lines. The receiver uses a lowpass filter to remove din and a high-speed comparator that recognizes the trapezoidal-shaped signal from the noise.

    Performance Issues MXIbus Performance

    It is often difficult to understand how a performance specification for a single component relates to the overall performance of your system. In the case of MXI, it is principal to understand not only the performance issues associated with the MXI link, but also the devices that communicate across the link. MXI works enjoy an embedded computer, using a direct hardware memory-map to eliminate software overhead between your computer and the VXIbus or VMEbus. Both MXI and embedded VXI computers can disburse shared-memory communication protocols and direct register accesses for potentially melodramatic performance improvements over GPIB. If your VXI instruments themselves finish not disburse these capabilities, however, your system performance using MXI or an embedded computer may exist no higher than a GPIB-controlled VXI system.

    There are several factors to account when comparing an MXI-equipped computer to an embedded computer. An MXI-equipped computer is functionally equivalent to an embedded computer. In fact, application software developed on a MXI computer using NI-VXI/VISA bus interface software can easily rush on an embedded computer and vice versa. There are subtle hardware timing differences, but there is no melodramatic performance disagreement due to architecture. MXI, for example, can remove roughly 100 ns more to fulfill a single VXI read or write than an embedded computer, because the MXI signals must propagate down the MXI cable at 10 ns/m. This subtle detail is measured in ns, and is negligible compared to the other factors that move your system performance, such as the execution hasten of your application software or your instruments.

    Often, the most principal performance issue to account when evaluating a computer for your system is the performance of the processor itself. Most applications disburse much more time computing, displaying, or performing disk I/O than actually performing I/O across the VXIbus or VMEbus. Current external MXI computers are more than four times as mercurial as the fastest embedded VXI computer. In addition, because of the physical space constraints of embedded computers, external computers often believe much more sophisticated architectures with faster processors, cache RAM, faster disk drives, and other benefits. Raw computing power can exist the single most principal consideration for the performance of your system.

    Data Transfer Rates

    A common benchmark for VXI computers is the obstruct Data Rate. This benchmark is simple for vendors to segregate and measure under exemplar conditions. It is principal to understand what obstruct Data Rate means to your application. obstruct Data Rate is the rate at which you can sprint a big obstruct of data to or from remembrance on an exemplar VXI device using back-to-back VXI transfers. It does not measure how mercurial the computer can process the blocks of data or store them to disk once they are moved, or whether your instruments themselves can actually match that data rate. Most applications are not limited by the obstruct Data Rate of the VXI interface hardware, but rather by the total time required to both sprint and wield the data, or by the rate at which the instruments themselves can generate or accept the data.

    Block Data Rate is simple for vendors to specify, but often difficult for users to relate to overall system performance. It is only one of many elements that move the actual throughput of your system. For example, obstruct Data Rate does not attest the processing power of your computer or the performance of the instruments themselves. In addition, a benchmark for obstruct Data Rate does not measure how mercurial you can control instruments using VXI Word Serial Protocol or random VXI reads and writes. The hasten for Word Serial communication and random VXI reads and writes is subject on the hasten of the processor and the particular VXI instruments.

    Local Performance

    The MXIbus does not demean the performance of the devices connected to it. Each MXI device can operate internally at full hasten in parallel with other MXI devices. Because MXIbus is a apt system bus with multimaster arbitration, the only time MXI devices must synchronize their operation is when they fulfill transactions that map across the MXIbus. When one MXI device performs a read or write that maps to a remote MXI device, the MXI hardware on both devices interlocks the bus cycle across the MXIbus to accomplish the transfer.

    MXI – An Open Standard

    The MXIbus specification was developed by National Instruments and announced in April 1989 as an open industry standard. A VXIplug&play core technology, MXIbus has been endorsed by the entire VXIplug&play Systems Alliance, including Tektronix, Hewlett-Packard, Racal Instruments, and GenRad. Because MXI is an open standard documented with a comprehensive specification, anyone can develop products that will exist integrated into an MXI controlled system.


    Dell EMC VxRail HCI builds on VMware Cloud Foundation | killexams.com real questions and Pass4sure dumps

    Dell EMC is tying its converged storage systems more closely around VMware.

    Dell EMC and VMware -- both subsidiaries of Dell Technologies -- introduced the fruits of joint engineering projects this week at VMworld 2018 Europe. The vendors previewed an addition to Dell EMC VxRail hyper-converged infrastructure and enhancements to the Dell EMC VxBlock converged infrastructure.

    The VMware Cloud Foundation on VxRail appliances is scheduled for general availability in 2019. Storage enhancements involve automated network configuration with Dell EMC SmartFabric Services, which allows VxRail to directly communicate with VMware NSX.

    For VxBlock 1000 converged systems, Dell EMC added tools to build infrastructure as a service, giving customers the capacity to launch vRealize management packs directly from the VxBlock Central interface.

    Dell EMC also expanded its open networking with the S5200 family of 25 Gigabit Ethernet (GbE) switches. VMware shops can disburse the top-of-rack switches to create 100 GbE data fabrics for NSX-virtualized traffic pitiable across racks.

    The companies launched a beta program to extend VMware Cloud on Amazon Web Services to on-premises Dell EMC VxRail environments.

    Dell EMC: uniform claim for converged, hyper-converged

    Hyper-converged infrastructure (HCI) is defined as computing, networking, storage and virtualization, packaged on an integrated appliance. The initial disburse cases centered on virtual desktop infrastructure and backup, but vendors are starting to position HCI for hybrid clouds.

    Dell EMC VxRack HCI appliances are turnkey, rack-scale systems that package Dell EMC PowerEdge servers and VMware vSAN storage software. VMware Cloud Foundation also includes vSphere, NSX software-defined networking and software-defined data center (SDDC) in an integrated software package.

    Dell EMC VxRail 4.7 marks a tighter product cadence with VMware, said Jon Siegal, a Dell EMC vice president of product marketing.

    "With this version, they will [integrate] the latest vSAN vSphere features in VxRail within 30 days of the latest vSAN vSphere release. Customers will fetch unique functionality more quickly," Siegal said.

    VMware partners with any big server vendors to sell vSAN as fragment of hyper-converged infrastructure, and Dell EMC sells other HCI products that don't involve vSAN. For instance, the Dell EMC XC sequence uses software from VMware's HCI rival, Nutanix. But Dell EMC VxRail is the main HCI focus for Dell and VMware.

    Rich Gagnon, CIO of the city of Amarillo, Texas, identified the tense integration between VMware and Dell EMC as a major factor in Amarillo's picking VxRail for its primary infrastructure platform. Amarillo currently has three VxRail clusters, with another one planned for its airport IT upgrade.

    Gagnon said he also evaluated Nutanix before implementing VxRail earlier this year.

    "A lot of it had to finish with the fact that Dell EMC and VMware are one company, and they're not going away," he said of his conclusion to pick VxRail.

    In a sprint aimed at edge environments, Siegal said two-node Dell EMC VxRail entry deployments with springy vSAN licensing will exist available in 2019.

    Converged infrastructure is sold as individual hardware components from validated OEM partners. Dell EMC VxBlock is based on Cisco servers and networking with VMware software, with the flexibility to match Dell EMC PowerMax, Unity, XtremIO and Isilon NAS.

    "We noiseless perceive a world where customers continue to disburse converged and hyper-converged infrastructure in their data centers. They made it easier to manage both [forms of convergence] from a single lens," Siegal said.

    VMware Cloud Foundation on VxRail embeds Dell EMC SmartFabric Services to automate configuration of storage networking. SmartFabric automatically creates VxRail clusters and allows VxRail Manager to manage them with the vCenter client.

    Current Dell EMC VxRail customers can fetch VxRail 4.7 as a free download. unique node deployments or expanding VxRail environments will believe to wait until December.

    Adding network automation to Dell EMC VxRail addresses issues common to hyper-convergence, said Eric Hanselman, a chief analyst at 451 Research.

    "Networking is enjoy the Rodney Dangerfield of the data center. It's been the hardest piece to automate, prerogative up there with storage in terms of risk aversion. Being able to bind the Dell EMC operational pieces to the vRealize orchestration [can have] significant operational benefits," Hanselman said.

    The Dell EMC S5200 top-of-rack switch was designed for VMware SDDC. It provides a physical network underlay to support NSX clients and services. Hanselman said Dell EMC's 25 GbE switch is a natural progression, as "people march toward more cost-effective 100 GbE" storage networking in hyper-scale environments.

    "There are a all set of capabilities the switch offers for greater configurability and manageability, but the titanic thing is getting to 25 [GbE] lanes."

    VMware executives touched on Project Dimension at Dell Technologies World in May, laying out plans to deliver SDDC as an on-premises managed service on physical storage infrastructure. Customers can symptom up for the beta project, which is expected to exist available in 2019.
