Entry Level SAN

I need help with some SAN storage advice.

I work for a small (20 user) software firm that needs some vm's.  We are unable to afford SAN's systems from the big vendors (10k+) so we are looking at some smaller devices.  I am concentrating on two,

http://www.dlink.com/products/?pid=688
http://www.amazon.com/Synology-RackStation-Rackmount-Redundant-RS810RP/dp/B003TWOKKW/ref=sr_1_1?ie=UTF8&s=electronics&qid=1298316003&sr=1-1

My goal is to create iscsi for backup purposes, and to provide logical disk space for my vm's.  Again, this is not for a large company.

Any advice as to which one is better?  Is it possible to perform database applications using this as a iscsi target with reasonable speed?  I don't need overkill, but I don't want it slow either.  Would Exchange, SQL and Pervasive be reasonable for 20 users using either of these devices?

Any advice is appreciated.

Have you considered a DROBO - http://www.drobo.com/products/index.php very reliable for VM use specifically the higher end ones. In addition they have excellent community support and are used a lot in the tech industry - specifically in the small/medium business space.

The Synology device is a rackmount so you may need a rack for it unless you have a suitable shelf for it. From that point of view, I'd select D-link for small company backups and test VMs. However, if you'll be using it for production, just make sure it is redundant. The D-link has only one PSU while Synology device has redundant power supply.

If you want better disk perfomance along with redundancy, the device should support RAID 0+1 (RAID10). RAID10 requires four disks minimum. Again, if you use it for production, a hotspare disk would be good to have, so RAID10+spare requires minimum on five disk bays, which Synology can't offer.

Also consider building a separate iSCSI network.

Yes, I looked at it, been including support, drobo is at least $4500 vs $1500 and $1700.  If there are any users out there that have experience from both products that can specifically recommend that the addtional cost is worth it?

I'd recommend DROBO based purely on their support which i have found to be nothing short of amazing. It also has advantages such as BeyondRaid http://www.drobo.com/products/drobosanbusiness.php?ID=Technology which builds upon and expands raids inherent limitations.

You could also take a look at QNAP devices:

The device above is around $2000.

I am also looking at SAN alternatives. In my initial research I was looking for $10K-15K solutions from HP but now this DROBO looks interesting. My only concern is no support for traditional RAID. I'm not sure how I feel about a proprietay raid system that I don't understand.

That qnap device looks quite good - is it hardware raid based though?

The only advice I can offer is stay away from Thecus! terrible build quality.

Thanks guys.  I have decided to go with the d-link.  The goal here was very low-end, and I think that will work for our needs.  I researched DROBO, and that does seem like a very good product, but it's the difference between 2k and 4k after hard drives.
