2-24 Compaq ProLiant Clusters HA/F100 and HA/F200 Administrator Guide
HA/F200 Fibre Channel Data Paths
The Compaq StorageWorks RAID Array 4000 storage system is the
mechanism with which the HA/F200 cluster implements shared storage. The
Compaq ProLiant Cluster HA/F200 minimum configuration consists of two
host bus adapters in each server, two 7- or 12-port storage hubs, two array
controllers per RA4000, and one or more RA4000s.
The RA4000 storage system has active data paths and standby data paths,
separated by two storage hubs. Figure 2-13 and Figure 2-14 detail the active
and standby paths of the minimum HA/F200 configuration.
