RAID

[sLiDeR]

I'd like to learn a bit about RAID and set up a server using RAID configuration.

 

Does anyone know of any good link to help achieve this??

 

Thoughts much appreciated.

Hi

 

This link here gives a good description of the different types of RAID available. It covers RAID 0, 1, 2, 3, 4, 5, 6, 10 and 50, but to start, just concern yourself with RAID 0 (Striped for performance, no redundancy), RAID 1 (Mirrored) and RAID 5 (Striped with Parity).

 

For Server 2003, software raid can be set up using Disk Management. If you need assistance with this, microsoft have this article for RAID 0.

 

Hope this helps.

RAID folklore says this:

The 0 in RAID0 is how much data you'll get back after a drive failure.

Take good note and if you're going to use 0 at all, make it 0+1 (stripe with mirror, ie four drives in pairs).

RAID in general:

For an overview of software-based in Linux:

 

linux software raid - Google Search

 

mdadm is the Linux software-RAID management utility:

If you're looking at RAID under Linux, you should also look at logical volume management (LVM):

 

Logical Volume Manager (Linux - Wikipedia, the free encyclopedia)

 

LVM lets you do useful stuff like take an instantaneous "snapshot" of a volume, say for backup purposes, without having to shutdown / disconnect / un-mount the volume.
