For me I have been working on spec'ing out a "HPC" cluster to run
Hadoop on large amounts of data and fell in love with the SGI
Cloud Rack C2.
I managed to come up with a configuration that had roughly 600
CPU cores, 1.2TB of memory and 300 1TB SATA disks in a single rack
and consumes ~16,000 watts of power with 99% efficient rack level
power supplies and N+1 power redundancy, rack level cooling as well.
Very cost effective as well at least for larger scale deployments,
assuming you have a data center that can support such density.
My current data center does not support such density so I came up
with a configuration of 320 CPU cores, 640GB memory, and 160x1TB
disks that fit in a single 24U rack, and consumes roughly 8,000
watts(208V 30A 3-phase) and weighs in at just under 1,200 pounds
Systems come fully racked, cabled & ready to plug in. Systems
are built with commodity components wherever possible(MB/ram/CPU/HD),
only custom stuff is the enclosure, cooling, and power distribution,
which is how they achieve the extreme densities and power
