RAID 5 or RAID 1

Call Manager 3.3 (2)

DL380

4 Drives

Should I start the install with Raid 1 or Raid 5? Everywhere I read 'pop a drive before you do anything' and have an extra spare. How does the RAID 1 mirroring look? 4 identical drives?

Re: RAID 5 or RAID 1

The whole "pop a drive" philosophy works with RAID 1. A copy of a mirrored set is complete on it's own and can be used as a backup. A drive from a striped set is useless without the other drives and cannot by itself perform as a backup.

In the case of 4 drives, the best practice is to create 2 mirrored sets. Then when the release notes recommend "pulling a drive", you can pull out both mirrors.
