Have a HP ProLiant DL360e Gen8 server.  I have installed 4 drives.  However when I try to create a RAID5 volume it tells me that I need to Add 'write cache'.  Is this something that's done administratively?  Or do I need to purchase parts to get this enabled?

Hi you need a 512 MB cache to enable RAID 5 support. Assuming you have B320i and B120i controller, you need this additional HP part: 631922-B21

I have a B120i, not both.

HP tell me this will not enable RAID5 on this server.

It does enable RAID 5 for the B320i but not for the B120i. Strange that it can have either but that there's only one part number for the system board in the maintenance and service guide.

If you have the 4 LFF disk model you could add 631667-B21 Smart Array P222 or if it's the SFF model you could add 631670-B21 Smart Array P420. Both are far superior to the Bxxx dynamic raid controllers.
