Just an fyi to the list, that ACNS is posting the message below to
http://service.status.msu.edu shortly. We will update Service Status as we
progress.
Service Status Content:
MSU’s central e-mail system – mail.msu.edu – data backups to tape were
temporarily suspended while alternative backup solutions are put in place.
The last back-up was completed on 10/23/07. The increased demands on
mail.msu.edu have placed a strain on the system; specifically, the main
storage filer. As a result, the system has performed at below-normal speeds
during the backup process.
While data backups to tape are currently suspended, the system does have
built-in redundancy to protect from data loss. For example, the storage
filer uses double parity raid volumes that protect system data in the
unlikely event that two drives fail at one time. It also has a number of hot
standby disks that are automatically provisioned in the event of a disk
failure.
New storage filer units are being purchased that will replicate e-mail data
to disk at a remote site. The backups are planned to resume on or before
January 7, 2008. Replicating data to disk instead of tape will allow for
near real-time data duplication and significantly reduce recovery times in
the event of a disaster. The new storage filer units should increase the
system’s overall performance and may allow us to increase disk quotas for
faculty and staff.
