Full Description:
Overnight a disk controller for one of the Exchange mailbox servers (mbxe-02) failed. No data was lost and the server continued to operate without error, but the disk write cache is currently inoperable. Parts have been ordered and should arrive later this morning, but there is a potential for users who have their mailbox on mbxe-02 to see delays in retrieving their mail.

The disc controller has successfully been replaced and put into operation. The write cache batteries are currently going through a charge cycle which should complete around 2:00 PM. Until that time the cache is disabled and there is still a potential for performance issues for users on that mailbox.\n\nWe will update this entry as the situation changes.
