SSI CEB

The Compact Electronics Bay Specification (CEB) is a standard form factor for dual processor motherboards defined by the Server System Infrastructure (SSI) forum. The specification is intended for value servers and workstations based on the Intel XEON processor.

An SSI CEB motherboard is 305mm x 267mm [12” x 10.5”] .

The SSI CEB specification was derived from the EEB and ATX specifications. This means that SSI CEB motherboards have the same mounting holes and the same IO connector area as ATX motherboards, although SSI CEB motherboards are larger in size than ATX motherboards. The rear panel aperture is identical to the EEB and ATX specification and expansion cards mounted on an SSI CEB motherboard appear much the same as they would on an ATX motherboard.

To standardize thermal behavior of such motherboards the position of the processors is defined, including the identification of the primary processor and the secondary. For motherboards with only one processor, it is recommended that the primary processor should be provided first.
