Glossary
Hot Swap
Replacement of a failed component while the system is running and operating
normally.
I
Initialization
The process of writing zeros to the data fields of a virtual disk and, in fault
tolerant RAID levels, generating the corresponding parity to put the virtual disk
in a Ready state. Initializing erases previous data and generates parity so that the
virtual disk passes a consistency check.
Instant Secure Erase
The process of securely erasing all data permanently on an encryption-capable
physical disk and resetting the security attributes.
K
Key Identifier
The user supplied clear text label used to associate the correct security key
with the controller. Examples: Encryption Key Identifier, Security Key
Identifier.
L
Load-Balancing
Load Balancing, a feature that is enabled with a redundant path configuration
on the PERC H800 card, ensures that a balanced number of disks are on each
port of the enclosure. The load-balancing architecture can also provide
additional performance increases in some workloads where the required
bandwidth can exceed that of what a single SAS link can provide.
