Rackable Systems has a goal: Create servers that use less power and produce less heat, thereby reducing the electricity costs for powering its rackmount systems and cooling the data center. Toward that end, the company has rolled out the 1U C1000, the latest in its line of DC-powered servers. But though C1000 users may gain savings in electrical efficiency, the product's use of Intel's dual-core 2.0-GHz Sossaman chips leaves something to be desired. The Sossaman is a chopped-down 32-bit chip that lacks support for EM64T (Extended Memory 64 Technology), Hyperthreading, SpeedStep and Virtualization Technology in a world where more and more applications are using these features. That might be too high a price for some companies to pay for saving some watts.
Because the C1000 is a half-depth system, you can squeeze twice as many C1000s in a standard cabinet as you can full-depth 1U Dell PowerEdge 1850s or Hewlett-Packard Proliant DLs, the two AC-powered, dual-core capable systems Rackable considers its chief competitors. That doubles the processor power (in terms of square-foot ratio) in a server environment when compared to other 1U systems. The CPU muscle-to-space advantages may be less obvious compared with, say, a similarly sized ProLiant blade server enclosure, which can support up to 16 blades, each using up to two CPUs, and up to six enclosures per 42U rack.

AI may force enterprises to rewire parts of their data centers so they are fully optimized to run such workloads. The question is do you use Ethernet or InfiniBand?
