Like David mentioned, ATA disks for backups should be pretty dumb and
inexpensive. We have been looking at the STK Bladestore. They offer a lot of
disk in a small footprint. Main advantage for us is that the library, disks,
and tape drives would all be under the same support contract. One contract, no
finger pointing between vendors... :-)

Subject: RE: [Veritas-bu] Using cheap ATA disk for virtual tape
We have been doing research on the EMC, it looks great - *but*
The way EMC prices their management software, is by the total size of the
disk,
independant of the price of that disk (ATA/SCSI/FC). You may not be saving
as
much as you think you are by going ATA in this case.
I am not in charge of that project, so my details may be a bit off.
I know we are looking at the Nearstore, but I have no input there.
Why not do DAS for this case? In my (humble) opinion, unless you need SAN
features
like snaping, etc., ATA disk should be CHEAP, and have the performance you
need.

I'm also working on a similar project. We do about 8 TB a week of backups,
so we're looking at getting a 24TB NearStore R150 from NetApp or an EMC
cx600 w/ATA drives.
Any thoughts on either of these boxes? Any alternatives I should be looking
at?

We are using an Arena Indy 2600, which gives 1.6TB for about $12k. While
the box has been very reliable, I could not get the monitoring ethernet port
to work,
and would not buy another one. I am looking at a Nexsan box, which costs
about the same, and seems to solve my problems.
We are using this for most of our incremental backups, and some of our
weekly fulls (where monthlies go offsite).

Subject: [Veritas-bu] Using cheap ATA disk for virtual tape
I am looking at using cheaper ATA disk drives for a staging area for
my backups. I am at a point were I need to by more tape drives or
implement a disk storage unit. The systems that I have been looking
at are STK bladestore and Quantum DX30. My company has a few remote
sites for which the backup performance would increase if it were to go
to disk first instead of tape. I would appreciate any discussion
concerning using ATA disk drives.
Thanks
