Well, off the top of my head:

2 x Storage Heads, 4 x 10G, 256G RAM, 2 x Intel E5 CPU's
8 x 60-Bay JBOD's with 60 x 4TB SAS drives
RAIDZ2 stripe over the 8 x JBOD's

That should fit within 1 rack comfortably and provide 1 PB storage..

What does one do for power? What are the power requirements when the system is first powered on? Can drive spin-up be staggered between JBOD chassis? Does the server need to be powered up last so that it does not time out on the zfs import?
