Little Help with RAID and SCSI settings on DELL PE2850

Basically you boot to that disk first and you can do a lot such as setup your RAID, network settings, input your product key, server name, domain credentials and all that. Of course that is if it is similar to the 2003 version.

It is recommended to use RAID 0 and that with a logical or physical failure you lose access to information. And in that case when you want to recover data no choice but to call a recovery company (ONRETRIEVAL, OnData, RECOVERY LABS, etc.).

It is safer to use a RAID 5 or RAID 10. But watch that also can fail even though a smaller percentage of possibilities.

Therefore it is important to keep a backup ensuring the data.

Who in the hell recommends RAID-0 on a server?

I think it's just the first logical step in stripe size for a drive. It's simple stripe but does increase performance without reducing space. As far as recommending, that's probably a good question. I'd like to hear some scenarios where RAID-0 was used and why. It seems like all the disadvantages to it are more headache than it's worth.

In a server RAID-0 is definitely not recommended. I'm a server admin by profession and none of my servers use RAID-0. RAID-1 or RAID-5 is pretty typical depending on how many drives my servers have. Usually I will do RAID-1 for the OS and RAID-5 for data.

Now on SANs, which is a different beast all together, I will do RAID-6 or RAID-50.
