Stripe Width
The number of striped SCSI drives within a drive group.
Striping
Refers to the storing of a sequential block of incoming data across multiple
SCSI drives in a group. For example, if there are 3 SCSI drives in a group,
the data will be separated into blocks and block 1 of the data will be stored
on SCSI drive 1, block 2 on SCSI drive 2, block 3 on SCSI drive 3, block 4
on SCSI drive 1, block 5 on SCSI drive 2 and so on. This storage method
increases the disk system throughput by ensuring a balanced load among all
drives.
System Drives
A system drive is equivalent to a “logical” drive. System drives are
presented to the operating system as available disk drives, each with a
capacity specified by the DAC960 Series controller.
Target ID
A target ID is the SCSI ID of a device attached to a DAC960PG
controller. Each SCSI channel can have up to 15 attached SCSI devices
(target ID from 0 to 6, and 8 to 15).
