2.2.3	Backplane

The RSS system backplane supports two CompactPCI buses accessible by both Redundant Hosts. In Active-Standby mode, the active processor board controls the buses (Active Host) and the standby processor board is isolated from the backplane (Drone mode). By using Active-Active- capable processor boards such as the ZT 5524, the system can be configured so that each processor board has access to one backplane bus (Cluster mode). The backplane has separate buses for active-to-standby processor board communication (COMM) and Host Controller functions. See Figure 4, “High-Availability System Backplane Architecture” on page 18 for an example of a typical High-Availability backplane.
