Chapter 1 – Introduction
Familiarizing yourself with the RAID controller
Overview
The hard drives in a RAID should match in size and speed. All drives in any
array should be identical models with the same firmware versions. RAIDs can
use any size drive, however the smallest drive will determine the size of the
array.
There's no set formula to determine how much cache memory to use, but as a
general rule, a workstation, with mostly very large files, such as for audio or
video editing and playback, graphics or CAD files, can benefit from a large
cache. File servers, with multiple random access of varying file size, generally
have little or no performance improvement with additional cache.
ACS-8990 disk arrays do not require the installation of different drivers for
use with different operating systems. ACS-8990 is independent and
transparent to the host operating system.
