Consider SONAS as well.  supposedly good TSM integration.

Re: [ADSM-L] Isilon backup






If you are going to use a filer, EMC doesn't support backups of its NAS
devices (that I have run into) except via NDMP dump.
Netapp on the other hand (or IBM-branded N-series, which is still a
Netapp) supports the -snapdiff api.

I just helped a customer convert about 40 hours worth of NDMP dumps that
normally took day,s to a single  2-hour -snapdiff TSM backup.  And size is
down from Terabytes a week to a few Gigabytes a day, because the -snapdiff
API lets you do a true incremental of the stuff living on the filer. ( See
the windows backup client manual for the requirements, they are very
minimal - essentially just requires 7.3 or higher of Ontap, and that's
been out for a long time.  )

As far as what is good for  VM's (and I'm speaking from a backup/recovery
perspective, I'm not a VMWare expert): no 2 filer-type devices are the
same.  As long as you are talking really low utilization, almost anything
will work.
If you are talking > TB of VM's, remember that for VM's we are back in the
sad old world of needing to full dump all the .vmdks, usually every 1-2
weeks.  So it's a matter have having the infrastructure IN the filer
(drives, cache, paths) and the infrastructure TO the filer (fibre
attachments or 10GigE between it and the TSM server) to get the throughput
you need.

Subject: [ADSM-L] Isilon backup

This may be a bit off topic but consider this a thread bump....

We have about 25TB worth of unstructured data spread across seven windows
servers using DFS.  We are using TSM with a monthly image backup as well
as daily journal based backups to collect the data but I'm concerned about
restore times.

I have convinced managment that we need a filer but they do not want to
purchase a file JUST to for file server backup/recovery.   They now want
to depoly test and dev VM's on the solution and possibly use the platform
for virtual desktops (VDI) and maybe even a workstation backup solution.

I spoke with Gartner and without hesitation the recommended the ISILON
over all other solutions.  For those of you that already have ISILON do
you feel it was the right choice?

We are an EMC storage shop so ISILON would be easy to sell but I feel
better about purchasing a proven solutions (NETAPP) rather than something
that EMC may chew up and significantly change.

My primary concern is still with the backup of the data contained on the
device along with virus protection and access control.  Please provide
your feedback.
