Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
The following are the supported storagesets for the HSG80 array controller:
■ RAID 0 (Stripesets)—physical devices combined in serial to increase transfer or
request rates.
■ RAID 1 (Mirrorsets)—physical devices combined in parallel to provide a highly
reliable storage unit.
■ RAID 0 + 1 (Striped Mirrorsets)—combined mirrorsets in serial and parallel
providing the highest throughput and availability.
■ RAID 3/5 (RAIDsets)—physical devices combined in serial (as RAID 0), but
also stored parity data ensuring high reliability.
See the The RAIDBook–A Source for RAID Technology for more information about
RAID technology.
Containers
Containers are comprised of storagesets, disk drives, and partitions:
■ Storagesets—Any combination of RAID storagesets.
■ Single disk drives (also called JBODs)—Any combination of single disk drives
that contain data with a distinct unit number and that are not part of RAID
storagesets.
■ Partitions—A configuration of single disk drives or a storageset where the data
storageset area is partitioned.
IMPORTANT: Any storageset can be partitioned in transparent failover mode.
However, storagesets are not allowed to be partitioned in multiple-bus failover
mode.
