MessageRight, that's exactly what we are working with right now. Actually some of the IBM blades can be beefy enough to serve as SQL servers within a cluster. The problem I am having is that the VLD drivers do not offer enough speed as advertised. NetApp wants some data from me that I just haven't had enough time to collect but I was also wondering if anyone else out there is using the combo of a filer/blade servers.
Before you ask, we need the VLD because SQL will not put the data on the UNC (\server\path) drive. The VLD makes a remote filer volume look like a local drive, thus fooling the SQL server on working.
Any comments would be appreciated.

It's worth noting that the IBM bladecenter can do fibre channel on the blade with the fibre switches embedded in the chassis. Very nice solution, actually.

Marcus,
Blade servers generally can and should be purchased with 2 disks for mirrored OS, SWAP and some binaries. Given that the smallest disk you can get now exceeds your DAS requirement by 8X plus I'd say they all get local DAS. This would allow you a single set of spares, cookie cutter software installation, etc. Also, I don't think a typical Win2000 system can easily boot without a disk
I'm not aware of any blade servers having single or dual fibre channel out of the back of each blade so DAS on the filer is out of the question. The HP Proliant BL 10e has Gbit out of the back with a Gbit consolidation switch built in to cut way down on the cable mess.
With regard to your data storage - everything should go onto the filer(s) for all the obvious reasons. Even the sources for the images that will go on the local DAS. You don't want to manage N file and OS spaces on N blades. One place to back up, no blade server is different from the rest, the world scales easily.. Free time to do something interesting.
Good luck,

Hi Toasters,
We are migrating many of the current servers to HP blade servers. The Server Team is considering connecting to the Filers/SAN on the back end for storage. I know this is not a problem. Some of the applications servers only need 4GB of space so leaving it on the DAS will be better. Want to best utilize the Filers since not every blade server is a good candidate for NAS if DAS will suffice. What are some criteria to use when considering connecting blade servers to the Filers? Any suggestion is appreciated.
cheers,
Marcus Bui
