Ha. Just to make you more jealous: we have 2 switches, a 24-Port Cisco
2970 and a 12-Port 3com SuperStack III 3812, both can be Fibre. 5KVA
UPS. 8-Tape LTO2 Quantum Autoloader. All in a nice 42U Dell rack with
a Rack-mount Keyboard and LCD Display.
About £25k worth and just powered up today ;-)

It's all GB, with some Fibre if things get hairy.

Will stick it all on the NAS and leave the 2850s for Audio/Video
encoding which is what they were bought for (but could be used), as I
don't think they need to be "that" available.
