Reconfigured the RAID disk on the IMAP email server (ms.emu.edu) so that the WRITE CACHE is enabled.

Although it was hoped this would be a fairly simple change, the reality was that an image of the 8gb disk had to be made and the RAID was then completely rebuilt. The actual reconfiguration effort began about 10am and was completed about 6pm. However, as a backup strategy in preparation for this procedure, the IMAP mail services were shutdown before the nightly backup of the server at 2am.

We believe this should improve the I/O performance of the IMAP mail server.
