I've started studying for my CCIE Data Centre with a bunch of lads in Oslo, Norway. This week and next, we're taking a deep dive into the UCS for the written exam. If you are like me in the sense that a UCS is a tad on the expensive side, and just a wee bit too large for the spare bedroom, and you need something to play with at home, Cisco have a UCS emulator.
I've only just started having a play, but it gives you a good feel for it. You can do quite a few things, but you can't run an OS on any of the blades.
There is a good youtube vid showing you had to install the UCS Emulator and get the basics up and running.
Some Extra CCIE DC Stuff
I hope to back with some more info once I've had a good play with it. Also, check out Tony Bourke's blog at Data Centre Overlords. He's also studying for the CCIE DC and currently has a great article about NPV and NPIV.
