If you are doing something to push ARM into low power servers I'd love to hear about it.

Definitely interesting, but it seems problematic that you have four cores that can address only a total of 4GB of memory, e.g. 1GB per core. Might be limiting for a lot of server apps. In practice it might be worse, with the system only able to handle 2-3GB (that's been my experience with 32-bit, non-PAE Linux).

Typo: 800 MHz not 8090 MHz. It's also ECC.

2 or even 4GB of RAM is sufficiant for many, many server tasks. I think a system based on that SoC is on par with the Pentium III Tualatin quad-processor systems build in 2001-2002. These system also had just 2 or 4 GB of RAM. But nevertheless served well.

here are a few more publicly announced Cortex-A licenses: Broadcom , NEC Electronics, NVIDIA, STM, Toshiba, Mindspeed Technologies, Freescale, Matsushita, Samsung, PMC-Sierra, Ziilabs. Why are there no solutions like Tilera's 36 or 64 core products. Are ARM's per core licensing costs too high ? 32 bit address limitations ? There are a lot of multi-core non ARM product our there, Cavium Networks (MIPS), Netlogic (MIPS), Freescale (PPC), Azul (Java VM), Plurality ...

Up to 4GB RAM may be a limitation to support multiple VMs with sophisticated service. The power saving may come down to how many VMs that can be supported on a ARM based server vs that can be supported by a x86 based server.
