Correspondingly, it is important to be able to perform the procedures needed to replace a defective hard disk without being forced to shut the system down. RAID also provides uninterrupted data access through disk mirroring and parity algorithms.

RAID is a cost-effective and easy-to-manage way to alleviate this bandwidth problem by distributing the I/O load seamlessly across multiple disks and controllers. As CoTW states most HP controllers are indeed backwardly compatible. Dual/Quad Core CPUs are quite powerful this days, and this isn't going to be a "high performance" NAS, but a two to four users code repository and maybe a webcache for
Attention! LSI also purchased Mylex at one point and sold ExtremeRAID controllers for a while, but have their own line of host-based RAID controllers. If the boot configuration is correct, Linux is able to run from a DAC960 RAID alone without the presence of further (auxiliary) hard disks.
