search for: x4100s

Greetings! Just joined the list, after looking at the mail archives and such. I have a few SunFire X4100s on the way, and I was wondering if anyone here has ever ran CentOS in a cluster environment? (I'm looking in Oscar's general direction.)

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these?
