Backplane Primer
If you are unfamiliar with passive backplanes, this short primer should offer some clarification.

Why Use a Passive Backplane?
Why use a passive backplane and Single Board Computer? The three primary reasons are: access to more expansion slots, availability of ISA slots, and significantly lower MTTR (Mean Time To Repair).

In general, motherboards are limited to a maximum of eight slots - and even that type of availability is difficult to find.  Passive Backplanes provide up to twenty slots. A 17" wide, rack mount chassis can accommodate a maximum of twenty slots, but one can build a backplane with more than twenty if the designated chassis is wide enough to accommodate the board. Also, with a smaller backplane, you can get a more narrow system using an SBC.

Intel and Microsoft decreed some time ago that ISA slots would no longer be supported. New motherboards only provide PCI slots. If you have an application that is served by a plug-in I/O, which is only available in ISA form factor, you are limited to looking for used or old stock motherboards or switching to a passive backplane. A passive backplane can provide up to twenty ISA slots. However, one or two of these slots would be occupied by the SBC, leaving eighteen available ISA card slots.

An SBC can be removed from a system by unplugging the cables, removing one screw, and pulling the card. None of the I/O cards need to be removed. A motherboard is buried under practically all of the componentry, thereby requiring total system disassembly to remove the motherboard. All I/O cards have to be removed and all of the screws holding the motherboard removed. If your application requires low MTTR, the only option is a total system replacement if you have a motherboard installed, or to use an SBC, installed in a passive backplane.

An additional factor in considering a passive backplane would be continued availability of an inherently stable design. Motherboards are consumer commodity items with limited availability. There is no guarantee how long you will be able to continue to source a specific motherboard. Single Board Computers and Passive Backplanes have much longer product life cycles. An example of the benefit of a passive backplane of SBC can be drawn from the process of acquiring FDA approval in the medical field. FDA approval is an expensive process. Every time you change a component such as the motherboard, you have to resubmit for approval.

One factor that differentiates passive backplanes and SBC’s from a standard motherboard is cost. Motherboards are made en masse and are very cheap. Passive backplanes and SBCs are made in much smaller quantities and cost considerably more than a motherboard.

Structure
A Passive Backplane provides the slots, but not the smarts, of a motherboard. Various motherboards provide for anywhere from one to eight I/O card expansion slots. The motherboard also provides the processor, processor support chip sets, memory, I/O, etc. A passive backplane needs the smarts provided by a plug-in Single Board Computer (SBC) to function. A passive backplane with an SBC installed is equivalent to a standard motherboard.

As with motherboards, passive backplanes provide a mix of I/O slots. These can be all ISA, a combination of ISA and PCI, or all PCI. Because of signal loading requirements, backplanes with PCI slots will also provide bridge chips. So, in the true sense of the word, these are not "passive" backplanes, but "active". For simplicity, they are all grouped as "passive" backplanes.

Single Board Computers can be had with a wide variety of features, including processor type and speed, available memory, video, I/O, etc. Regarding a passive backplane, the only concern will be the connection between the SBC and the backplane. An SBC looks like any other plug-in card. Hanging from the bottom will be an ISA connector and possibly PCI and PICMG connectors if the board supports PCI.

passive backplane connector detailNote that a PCI SBC will work in an all ISA slot backplane. An ISA-only SBC will work in an ISA/PCI backplane, but will not provide any PCI support (PCI slots will not be active). The ISA signals are carried on the ISA edge connectors and the PCI signals are carried and controlled by the PICMG edge connectors.

It should be noted the PCI Express bus structure is entirely new regarding the CPU connectors. The PCI Express SHB boards, such as the NLT and NLI, will only fit in a PCI Express backplane. Loss of functionality isn’t the concern – these boards simply will not fit in the connectors.

PCI Express can be described as parallel serial. Each channel provides packets of data serially, but in parallel data streams. The more channels to a connector, such as x8 or x16, the higher the available bandwidth to that connector. The SHB has a limited number of channels, some of which are used internally, some to external PCI Express slots, and others to bridge chips for driving PCI and PCI-X slots. See the PCI Express Backplane Reference Manual for a complete explanation of PCI Express backplane structure and use.

An ISA-only backplane can have the SBC installed in any slot. A PCI and PCI-Express backplane will provide dedicated SBC slot(s) and the SBC must be installed in one of these for the system to work properly.

Segmented Backplanes
split backplaneSegmented or split backplanes provide for multiple independent SBCs to be used in the same backplane. Each SBC has a group of dedicated slots and only power and mechanical support are shared. In theory (and practice), a 20-slot backplane could be split into 10 segments, which would allow ten SBCs and ten I/O cards to be installed in a single 4U chassis. Because the SBCs share power, each SBC cannot be individually turned on/off. However, each SBC can be provided with its own reset switch. Imagine the processing power available with ten 3GHz dual-Xeon SBC's in a single 4U enclosure!

Custom Backplanes
custom pci backplaneAs with our Custom Chassis units, Chassis Plans can provide you with custom backplanes with any slot configuration mix, any number of segments, or any special mechanical features. It is possible to add circuitry to the backplane to provide functionality not available in a plug-in card or to conserve I/O slots. There is a fifty piece minimum order for custom backplanes and NRE charges will apply. We have over thirty custom designs available with no NRE charges applicable. Contact the Chassis Plans sales department today with your custom requirements and receive a quick quotation!
