Storage Subsystem
The storage subsystems for the ProLiant Cluster HA/F500 are the Compaq
StorageWorks RAID Array 8000 (RA8000), the Compaq StorageWorks Enterprise
Storage Array 12000 (ESA12000), the Compaq StorageWorks Modular Array 8000
(MA8000), the Compaq StorageWorks Enterprise Modular Array 12000
(EMA12000), and the Compaq StorageWorks Enterprise Modular Array 16000
(EMA16000).
The RA8000/MA8000 and ESA12000/EMA12000/EMA16000 are high-capacity
storage subsystems that support both single and dual RAID controllers. The
RA8000/MA8000 and ESA12000/EMA12000/EMA16000 support up to 72 disks
per controller or controller pair.
High-availability components of the storage subsystems include redundant power
supplies, fans, controllers, cache battery backup, hot-global spare drives, and
multilevel RAID architecture.
For more information about the storage subsystem components, refer to:

Cluster Interconnect
The cluster interconnect is a data path over which nodes of a cluster communicate.
This type of communication is termed intracluster communication. At a minimum,
the interconnect consists of two network adapters (one in each server) and a cable
connecting the adapters.
