blocks, aligned to start at disk addresses that are multiples of 2
Kbytes from the beginning of the logical disk.
RAID 5 Three to sixteen disk modules that use disk striping, in which the
hardware writes to or reads from multiple modules simultaneously,
with high availability provided by parity information on each
module. The ideal number of disk modules in a RAID 5 group is five.
RAID group A group of disks on which you bind one or more LUNs of a specific
RAID type. The RAID type is that of the first LUN bound on the
group. Storage systems must run a specific revision of FLARE
software to support RAID groups.
RAID group storage

A storage system with SPs running a revision of FLARE software that
supports RAID groups.

operating system and uses a disk-array storage system for data

Server Utility An alternative tool to using the Host Agent. Similar to the Host
Agent, the Server Utility also relays configuration and status requests
from Navisphere clients to CX-Series or FC-Series storage systems.
However, unlike the Host Agent, the Server Utility does not push
LUN mapping information back to the storage system or periodically
retrieve information from the storage system.
