CompactPCI Backplanes, Plus I/O and Serial

Compact PCI Evolution

3U Compact PCI Family Backplane Interconnect Roadmap

CompactPCI Serial Overview

Moves the existing CompactPCI parallel bus architecture to serial high-speed interconnects. Switches and bridges are not needed for a system configuration of one system slot and up to eight peripheral slots. Using a new rugged connector allows for a signal density of up to 184 pin pairs (3u) and transmission frequencies of 12 Gb/s, while maintaining the proven 19” mechanics of IEC 1101 and hot swap.

System slot supports 8 PCI Express Links (6 by 4 lanes, 2 by 8 lanes), 8 SATA/SAS, 8 USB 2.0/3.0 and 8 Ethernet interfaces plus signals for general system management (reset, IPMB, hot swap, geographical addressing, etc).

It is supplied with 12V (60W per 3U, 120W per 6U slot).

Peripheral slots offer 1 PCI Express link, 1 SATA/SAS and 1 USB 2.0/3.0 interface. Each slot can support up to 8 Ethernet interfaces to build a full mesh. All interfaces are accessible at the same time. It is supplied with 12V (60W per 3u, 120W per 6U slot).

Since the pin assignment of the system slot and peripheral slots are congruent, it is possible to insert a system board into each peripheral slot to support symmetrical multiprocessing. The star topology is equal for PCI Express, SATA/SAS and USB. All peripheral slots are identical except two that are connected via PCI Express links by eight lanes. Ethernet is wired as a full mesh. Transmission is based on the proven standards for copper connections up to 10Gbase T to allow configurations of redundant, safety-critical systems.

Backplane Topology

Single Star Architecture

The links (SATA/SAS, USB2/3, PCIe, Ethernet) are arranged as a simple star architecture.

Full Mesh Architecture

The full mesh architecture is implemented for Ethernet. Each slot (the system slot and up to 8 peripheral slots) has a dedicated connection to all other slots via the backplane
