Bus Architecture Terms To Know

VME
The VMEbus standard traces its roots to work done by several companies, including Mostek, Motorola, and Signetics, in the early 1980s. The acronym VME actually stands for Versa Module Eurocard (VERSAbus was a bus developed by Motorola in the 1970s). VMEbus modules are used to construct powerful and rugged (industrial) computer systems with applications in a variety of industrial, commercial, and military applications. The regular VMEbus standard accommodates 32 bit address and data buses. Data transfers are 8, 16, or 32 bytes wide. The newer VME64 standard makes more efficient use of unused bandwidth to enable 64 bit transfers.

ISA
ISA (or Industry Standard Architecture) is one of the most commonly used expansion buses in the PC world. This design specification allows components to be added as cards plugged into standard expansion slots in IBM and compatible personal computers. ISA was originally introduced in the IBM PC/XT with an 8-bit data path. In 1984, when IBM introduced the PC/AT, ISA was expanded to permit a 16-bit data path. (A 16-bit ISA slot is actually two separate 8-bit slots mounted end-to-end.) Through the years, manufacturers have resisted modifications to the standard, allowing it to remain relatively unchanged since that time.

PCI
Peripheral Component Interconnect (PCI) is a specification introduced by Intel Corporation that defines a local bus system that allows up to 10 PCI-compliant expansion cards to be installed in the computer. A peripheral bus commonly used in PCs (IBM compatible and Macintosh), PCI debuted in late 1993. PCI can exchange data with the CPU either 32 bits or 64 bits at a time, as well as allowing intelligent, PCI-compliant adapters to multitask concurrently with the CPU using a technique called bus mastering. PCI also enables the identification of peripheral cards and works with the OS and BIOS to automatically set resource allocations for compatible peripherals. This is more commonly referred to as plug and play. The most current revision of the PCI specification allows a bus clock speed of 66 MHz, which results in theoretical throughput of 266 and 533 MBps.

CompactPCI
CompactPCI is a modern, high-performance industrial bus based on the standard PCI electrical specification, on a rugged 3U or 6U Eurocard packaging. The Eurocard describes a family of European-designed printed circuit boards that use 96-pin plugs rather than edge connectors. The CompactPCI board uses a 2-mm metric pin and socket connector and can be front-loaded into a rack mount system. Cards are mounted vertically allowing for natural forced air convection cooling. The power and signal pins on the CompactPCI connector are staged to allow support for hot swapping, a feature that is very important for fault tolerant systems. Compact PCI features include: 32 or 64-bit synchronous data bus, 32-bit address bus, 133 or 266 MBps data transfer rate, multiprocessing, up to 8 slot backplanes, bridging from PCI to PCI or from PCI to other buses, and plug and play.


PCI Takes A Stand

BY CURT NELSON

"Marketing, marketing, and more marketing," would be a good title for many of the articles and seminars being produced extolling the virtues of CompactPCI (CPCI) over standard PCI technology. The unfortunate outcome of this type of marketing is that people actually view the information as if it were unbiased technical data from which they can make intelligent investment decisions. But unfortunately, this is not the case. And in order to make an informed decision about CPCI versus PCI, the buying audience must become self-educated to make a proper decision. Please note the information below as a partial comparison.

Regarding open standards and the PCI bus: CompactPCI architecture and the standard PCI architecture utilize identical silicon, firmware, software, operating system, drivers, and applications detect no differences between the two. Both CPCI and standard PCI conform to the same base PCI SIG performance specifications. There is no bandwidth difference between the two, and functionally, they are identical in performance. Conventional PCI in the industrial passive backplane format has long been specified through the open standard PICMG v1.0 promulgated through the same organization that developed CompactPCI.

Relative to reliability: The idea that CPCI is inherently more reliable in a telco environment that standard industrial PCI passive backplane architecture is incorrect. Industrial computer offerings using standard PCI bus architecture have passed the rigorous NEBS Level 3 testing requirements as well as 10G droop tests. Standard PCI edge architecture meets or exceeds the minima set by the PCI SIG specifications and complies with the industry standard PICMG 1.0 specification.

Industrial computers provide extensive cooling that can issue no more than 10 degree C rise over ambient temperature. Alarm and monitoring functionality is offered to provide visual and audible alerts in the event of any heat related problems. CPCI relies on normal convection or the user/integrator/manufacturer to add external fans as desired. And most importantly, vertical cooling significantly limits the density in which the units can be mounted in a telco rack environment, making CPCI much less space efficient making CPCI anything but a "compact" solution.

Also of interest is that PC development is done around the demands of the desktop industry in line with PCI bus architecture specifications. New advancements will always be available for the edge connector technology first. Just because the standard PCI architecture is easy to redesign into the CPCI form factor, doesn't mean it is inexpensive. CPCI will see the latest advancements only if peripheral vendors see a large enough demand to make the transition profitable.

Standard PCI and CPCI architecture offer the same performance standards relative to reliability, flexibility, and open standards. The difference comes down to cosmetic appeal. Standard PCI and ISA edge technology is performing in telco environments worldwide and has been doing so with NEBS Level 3 certifications for many years. CPCI and standard PCI architecture will perform equally in all respects except total cost of ownership, where CPCI is significantly higher.

In summary, it appears that the majority of those interested in the CPCI architecture are those who want the same look and feel of VME bus technology. The technological decision as it relates to functionality, reliability, and architectural flexibility is equal either way. And the most cost-effective solution is current passive backplane PCI technology. We invite you to do the research and be the final judge.

CompactPCI: Coming On Strong

BY JOE PAVLAT

Open standards have been the norm in the computer industry since the early 1980's. While their adoption by the telephony and telecom industries has been recent by comparison, equipment manufacturers realize that incorporating open industry standards broadens the market for their products. It also encourages competition by vendors to these equipment builders, lowering prices and increasing the range of available products. Desktop PCs are a great example of this phenomenon and they have been a popular platform for telephony applications for many years. PCs offer a lot of compute power and they are cheap, but they are less than robust and product lifetimes can be measured in months, at best.

The desire for improved product stability, plug-in processor cards, and chassis that provided better cooling, more slots, better serviceability, bigger power supplies, and rack mounting led to the development of the Passive Backplane PCI/ISA standard in 1994. Big, beefy boxes with better cooling and large drive bays emerged and have been a very popular choice for telephony suppliers. But, many of the problems inherent to the PC architecture remain. Cooling is sub-optimal. Secondary voice buses are typically routed on flat cables on the top of cards, and replacement or maintenance is difficult. And, the ISA bus is going away. Still, the low cost, high performance, and wide availability of PCI peripherals have made this a popular architecture.

CompactPCI was developed to provide a superior mechanical structure for PCI electronics. The Eurocard packaging standards were the key. CompactPCI utilizes a vertical passive backplane and cards plug directly into the front or rear of a chassis without partial disassembly of the box. The vertical card orientation provides optimal cooling, with power dissipation ratings of up to 1000W per 19" chassis. That hot air rises is the reason chimneys are vertical, not horizontal!

CompactPCI uses reliable, gas tight 2-mm metric connectors for all signals. The PCI bus itself is fully defined for 64 bits and up to three additional connectors can be added to 6U boards for a total of 315 additional pins. These are ideal for applications like telephony that require sub-buses like H.110 and lots of I/O. The CompactPCI Computer Telephony Specification, released in early 1988 and supported by major voice board suppliers provides a stable framework for building voice and VoIP systems.

CompactPCI cards plug directly into the front of the chassis and are hot swappable, which reduces downtime. Metal front panels provide additional environmental protection and allow systems to meet tough international safety and emissions standards. The CompactPCI specification also permits systems to be built that bring I/O into the rear of the chassis on a semi-permanent basis through passive 80-mm transition cards that route I/O through the backplane to the front card. This means that when a front circuit card is replaced, all of the cables associated with that card do not have to be unplugged and replugged.

Hundreds of CompactPCI cards are now available, including virtually every imaginable processor and I/O interface, including T1/E1, voice, LAN, and WAN. Chassis ranging from low cost 8 slot to high end, 21-slot Bellcore NEBS compliant boxes for mission critical applications give the CompactPCI platform great scalability and flexibility. CompactPCI has arrived!

Joe Pavlat is Director of Strategic Planning for Motorola Computer Group (www.mcg.mot.com). He is also President of the PCI Industrial Computer Manufacturers Group (PICMG), an industry consortium of 440 companies worldwide. PICMG developed the passive backplane PCI/ISA and CompactPCI specifications. For more information on PICMG, visit their Web site at www.picmg.com.


Industrial Computer Points to Ponder

We asked Laura Skinner, vice president and general manager of the telecom integration division at Ingram Micro (www.ingrammicro.com), what buyers should look for when considering the purchase of an industrial computing platform. Here’s what she had to offer:

  1. Reliability: Use of Redundant and Hot-Swappable components to maintain maximum system availability. No business can afford to be without telephone service, therefore your platform for a PC-based system or VoIP solution must be reliable.

  2. Power Supply: Examine the power draw of the voice boards the solution will use and verify that it does not exceed the capacity of your power supply. Some boards provide analog ring generation directly on the card, which places a much greater load on the platform's power supply.

  3. Capacity: How many slots are available for telephony boards? What is the maximum port density possible, based on quantity and type of slots. (i.e., if it is an ISA card, how many available ISA slots are there?) See the power supply issue above for further issues regarding maximum capacity.

  4. Positive Airflow: Most PC's in this class provide positive airflow and filtering systems to ensure that "industrial" byproducts (dust, etc.) do not get drawn into the system, thereby avoiding problems that can shorten the components' life span, or cause malfunctions.

  5. Rack Mountable: This has become less of an issue since many "non-industrial" server-class systems have become rack mountable, but for many IT/IS managers, it is still an important feature.

  6. Open System: Systems based on Industrial PC platforms generally cost less and are easier and cheaper to repair should there be a service issue. This makes them popular with IT/IS Managers as well. Multiple sources for parts means lower cost for repair.

  7. Custom Configurations: The manufacturer or integrator should be able to comply with your requests for customizing the system to your specifications.

  8. Self-Monitoring/Remote Notification: A parameter which exceeds a pre-programmed threshold, such as ambient temperature within the chassis or power supply voltage, could initiate a dial-out on a phone line to notify the system administrator of potential or actual problems.

  9. Redundant and Powerful: A industrial PC - as bullet-proof, redundant, and powerful as a traditional phone system - allows CTI products like PC-based PBXs, voice mail systems, and Internet telephony gateways to stay up and running with the same reliability as traditional "proprietary" PBX's.

GLOSSARY

Backplane - Similar to a motherboard, a backplane is a circuit board with sockets, which other boards and expansion cards may be plugged into. A backplane may be active, in which logical circuitry performs the computing functions. It may also be passive, in which circuitry is located on a plug-in card, and failure rate is significantly low. It is easier to repair and upgrade components on a passive backplane.

Bus - A bus is the collection of wires that allow data to travel throughout a computer. The bus connects internal components to the CPU and main memory. The size of the bus determines how much data can be transferred. (See Bus Architecture Terms To Know for more information.)

Chassis - The rack or case that houses an industrial computer's circuit boards, power supply, and wiring, and contains slots for expansion boards. Chassis are typically available in rackmount or tower models in which components are stacked on top of one another, or more compact desktop models.

EMI - Electromagnetic interference.

Fault Tolerant - If a computer is protected against software and hardware errors when a power failure occurs, it is said to be fault tolerant. Usually, the system will switch to other equipment to protect against failure.

Hot Swappable - Describes a component of an industrial computer system that may be replaced without interruption to the rest of the system.

Integrated Drive Electronics (IDE) - IDE is a standard interface for disk drives that incorporates drive controller functions directly into the hardware. An IDE drive is attached to the motherboard instead of a controller card, and may also be a CD-ROM drive.

ISO 9000 series - This set of standards, established by the International Standards Organization in Paris, provides quality assurance and management guidelines for products. A company may receive ISO 9000 certification, ensuring that their product was developed under these guidelines.

PCI Industrial Computer Manufacturers Group (PICMG) - This consortium of vendors advocates open standards in industrial computing. The group has established specifications for CPU boards and backplanes that allow products from different vendors to be used interchangeably. The group has also specified CompactPCI standards.

Portability - When an operating system may be moved from one hardware platform to another with minimal recoding, it is said to be portable.

Redundant Array of Inexpensive/Independent Disks (RAID) - Several disk drives are grouped together and data is mirrored over multiple disk drives. If one drive fails, the data may be retrieved from the other drives for redundancy and fault resilience.

RFI - Radio Frequency interference.

Scalability - If a system is built so that additional components may be easily added, it is known as scalable. Scalability also refers to the system's "adaptability" to increased demands.

Small Computer System Interface (SCSI) - The SCSI bus and parallel interface standard allows components such as hard disks and tape drives to communicate with a peripheral device that uses embedded intelligence. The interface supports one master host and seven or more slave peripherals, connected in a daisy chain through a cable to a SCSI expansion board known as a host adapter.
