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.
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.
A storage system with SPs running a revision of FLARE software that
system supports RAID groups.
The storage system provides replace under power capability,
allowing you to replace, for example, a disk or a fan module without
powering down the storage system. Applications continue while you
replace the failed module.
route See primary storage-system route.
S
See primary storage-system route.
A storage system or SP that runs the Storage Management Server
Server software.
server In the context of disk-array storage systems, a processor that runs an
operating system and uses a disk-array storage system for data
storage and retrieval.
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.
