Description
stripe size
The total drive space consumed by a stripe not including a parity drive. For example, if a stripe
contains 64 KB of drive space and has 16 KB of data residing on each drive, the stripe size is 64
KB and the strip size is 16 KB.
A larger stripe size produces improved read performance, especially if most of the reads are
sequential. For mostly random reads, select a smaller stripe size.
striping
Drive striping writes data across two or more drives. Each stripe spans two or more drives but
consumes only a portion of each drive. Each drive, therefore, may have several stripes. The
amount of space consumed by a stripe is the same on each drive that is included in the stripe.
The portion of a stripe that resides on a single drive is a strip, also known as a stripe element.
Striping by itself does not provide data redundancy; striping in combination with parity provides
data redundancy.
strip size
The drive space consumed by a strip. For example, if a stripe contains 64 KB of drive space and
has 16 KB of data residing on each drive, the stripe size is 64 KB and the strip size is 16 KB. The
stripe depth is four (four drives in the stripe). You can specify strip sizes of 8 KB, 16 KB, 32 KB, 64
KB, 128 KB, 256 KB, 512 KB, or 1 MB.
UPS
Uninterruptible Power Supply. An electrical device that provides power off of a battery when
the input power source (AC) fails.
