Koko (the LCSR NetApp)
The new NetApp
LCSR now operates a NetApp FAS3140 filer.
It allows us to centralize our file management for the clusters we
manage.
It provides fast, reliable storage via dual-parity RAID 4 technology.
It provides a snapshotting system which allows operators to complete file
restores quickly without the need to access tapes.
As currently configured
(August, 2010),
it can provide up to about
19 TB
of disk storage.
Move to NetApp
We have been using a NetApp for home directories for several clusters
(faculty, research, grad, undergrad, internet lab among them)
and some project usage since late 2002.
Change in backup policy
In response to the recently enacted
law regarding public access to government records,
we have had to rethink our backup policies.
A request coming in for "all electronic records regarding
xxx",
could, under our old backup scheme, take large, even unmanageable
amounts of our time and resources searching old backup tapes for
potentially relevant files.
After input from federal agencies and other departments at the
university, we have determined that keeping backups on the NetApp for
up to two months and providing the DCIS faculty with CD copies of their files
beyond that point will leave all available files accessible and under
user control.
The NetApp
snapshotting mechanism
provides online
nearly
immediately accessible backup copies of all
files online at the time snapshots are taken.
We also have in place a mechanism for producing CD archives of DCIS faculty
home directories to be given to the faculty themselves.
