The regeneration of all data to a replacement drive in a redundant virtual
drive after a drive failure. A drive rebuild normally occurs without
interrupting normal operations on the affected virtual drive, though some
degradation of performance of the drive subsystem can occur.
The percentage of central processing unit (CPU) resources devoted to
rebuilding data onto a new drive after a drive in a storage configuration
has failed.
A method of undoing the configuration of a new virtual drive. If you
highlight the virtual drive in the Configuration Wizard and click the
Reclaim button, the individual drives are removed from the virtual drive
configuration.
The user-defined rate at which a drive group modification operation is
carried out.
A property of a storage configuration that prevents data from being lost
when one drive fails in the configuration.
A virtual drive that has redundant data on drives in the drive group that
can be used to rebuild a failed drive. The redundant data can be parity
data striped across multiple drives in a drive group, or it can be a
complete mirrored copy of the data stored on a second drive.
A redundant configuration protects the data in case a drive fails in the
configuration.
When you use the Replace Member procedure, after data is copied from
a hot spare to a new drive, the hot spare reverts from a rebuild drive to
its original hot spare status.
A drive property that indicates the revision level of the drive's firmware.
Acronym for Serial Attached SCSI. SAS is a serial, point-to-point,
enterprise-level device interface that leverages the Small Computer
System Interface (SCSI) protocol set. The SAS interface provides
improved performance, simplified cabling, smaller connectors, lower pin
count, and lower power requirements when compared to parallel SCSI.
Acronym for Serial Advanced Technology Attachment. A physical storage
interface standard. SATA is a serial link that provides point-to-point
connections between devices. The thinner serial cables allow for better
airflow within the system and permit smaller chassis designs.
