OK, Veritas 9.1 and our 6 tape Autoloader are getting beat to death now, and can't seem to finish within our backupwWindow each night. It's my job to find a solution that will work, yet stillincorporate our Autoloader since my boss supposedly had to beg upper management to blow the 15 grand on it.

Total Data ~1.4 TB on full backups
My idea:Standalone server running Win2003 Server
3ware Escalade 9500s-8 or comparable 8 channel SATA Raid Card in Raid 5
qty (8) 300Gig Seagate NCQ supported SATA drives
Dell Poweredge 2600 server with single 2.8 XEON and 2 Gigs DDR
Bakup Exec 10.0

That would give us 2.1TB useable space for backups, and I could then run Veritas all day long on it to allow our LTO Drive to write it to tape.

This soultion would run ~6 grand.

are there any preconfigured NAS devices in this price range I could look at as an alternative. I just need a box to hold around 2TB in RAID-5 and then allow Veritas to do it's thing. I also figure restores would be much faster if by chance I didn't have to pull from an offiste tape in the rotation.

Any suggestions? I need to get this project rolling.
Thanks guys.
 
If this box's only role will be backup I/O and nearline storage, does it really need 2GB of RAM? Maybe I'm missing something, like a gi-f'ing-normous cache in RAM, but 512MB seems like plenty for this mission. Also, consider Maxtor MaxLineIII - 16MB buffer for blazing linear performance and designed from the ground up as an enterprise drive for 24/7 power on operation. It also brings NCQ and the other features of SATA-II to the table. Mere suggestions from me.
 
Maxtor's a re a great choice. I have the 300GB 16Mb Cache version in my home rig.

2 Gigs is overkill but it seems to be a standard purchase around here (Non-profit org).

I offered to build the server to save some bux, but my boss is big on having support on the boxes. So Dell it is.
 
FYI, if you are doing a brick level backup of exchange mailboxes, that is your problem (timewise) Even backing up to hard drives will not speed up that job, it will only run at ~45MB/min there is no getting around that. (this is my problem too)

So for a solution, I just got a separate tape drive to just run the mailbox backup, and run it as a separate job. That way it can start earlier in the night and finnish on time. (run both jobs at once) Everything else backs up to my AIT drive at ~300 - 450MB/min.

Of course my total data set is 100GB, not 1.5TB so you may just be dealing with the drive speed limit. But do make sure that it is the autoloader that is your limit.. it may not be. (what kind of network are you going over?) To test, make a smaller backup to local drives on the backup server and compare it's throughput to what your logs say your autoloader is getting.

Just go all the way and get the 400GB 7200.8s. While you're at it, make sure your controller makes hot-upgradable arrays so you can just pop in an extra drive when you need more space.
 
Yeah I'm looking into a Dell Poweredge 1800 with a 6 way controller. My Boss likes having the Dell Support. If that gets too out of hand, I'll by an 1800, slap the 3Ware in there, and grab 8x400giggers and go balls out on it.
