HP ProLiant Cluster HA/F500 for Enterprise Virtual Array Setup and Installation Guide

Overview of the ProLiant Cluster HA/F500 for Enterprise Virtual Array
ProLiant Cluster HA/F500 Configuration
The ProLiant Cluster HA/F500 for the Enterprise Virtual Array is a cluster with
two FCAs in each server, two switches, and two storage controllers. In an HA/F500
configuration, each storage controller pair can be attached to a maximum of
240 drives.
The servers in a ProLiant Cluster HA/F500 are also connected to a local area network
(LAN), usually referred to as the client LAN, through which users access the cluster.
There is also an interconnect connecting the two servers, frequently referred to as
the cluster interconnect. The interconnect is used to allow the two servers to
communicate without the delay potentials inherent on the client LAN.
Figure 1-1 and Figure 1-2 show configurations without any single points of failure.
To allow dual paths to the storage, the Secure Path software must be installed on all
servers. With Secure Path, data can flow simultaneously over both FCAs to the
storage subsystem, and you can perform load balancing over the two paths to help
maximize performance.
