How much space do you need?  Are you virtualizing?  Unless you have a specific reason not to, you SHOULD be virtualizing.  My inclination (as I don't really trust RAID 5 (or 6, or 10, or 0+1) is to go with 2xMirror and POSSIBLY a hot spare or possibly a single disk for putting non-essential resources on.

Single server you could go raid 5 with a hotspare which will give you 1.5Tb space

is it not worth mirroring the OS and creating a data drive with raid 5?

Trying to configure RAID 5 for which there is no option, however I have a warning message saying.

Dynamic Smart array B120i Raid in Embedded slot support optional write cache but none was detected. adding write cache will improve performance and enable the creation of RAID 5 Volumes

I have gone to the controller options and enabled Physical Drive Write Cache State to Enable but I still do not get the option to create RAID 5 any idears

What kind of server is this?  Might have to use the utilities provided (like the dell or hp disk etc which prepares the system for the operating system).  You should be able to boot into the raid, delete the array and reconfigure the raid array for a raid 5 and enable the write cache.

You did state this was a new server so I am under the assumption there is no data on it so deleting the raid array will remove the data.

The Server is a ML350EG8

I can boot into the Raid Configuration but just don't get the option for RAID 5, it says it can do RAID 5 With Write Cache Enabled.

There is no Data on it I have tried recreating etc

Just looked at the spec for the server and found the following

•RAID 5 with optional 512MB FBWC1

so the options I have for raid is Raid - 0  or Raid 1+0

What do you think
