A recent press release from AppliedMicro (Applied Micro Circuits Corporation) announced that the company’s X-Gene server on a chip technology would be used in an upcoming HP Project Moonshot server.
An HP Moonshot server (expect the X-Gene version to be at least slightly different).
The X-Gene is a 64-bit ARM SoC that combines ARM processing cores with networking and storage offload engines as well as a high-speed interconnect networking fabric. AppliedMicro designed the chip to provide ARM-powered servers that will reportedly reduce the Total Cost of Ownership of running webservers in a data center by reducing upfront hardware and ongoing electrical costs.
The X-Gene chips that will appear in HP’s Project Moonshot servers feature a SoC with eight AppliedMicro-designed 64-bit ARMv8 cores clocked at 2.4GHz, four ARM Cortex A5 cores for running the Software Defined Network (SDN) controller, and support for storage IO, PCI-E IO, and integrated Ethernet (four 10Gb Ethernet links). The X-Gene chips are located on card-like daughter cards that slot into a carrier board that has networking fabric to connect all the X-Gene cards (and the SoCs on those cards). Currently, servers using X-Gene SoCs require a hardware switch to connect all of the X-Gene cards in a rack. However, the next-generation 28nm X-Gene chips will eliminate the need for a rack-level hardware switch as well as featuring 100Gb networking links).
The X-Gene chips in HP Project Moonshot will use relatively little power compared to Xeon-based solutions. AppliedMicro has stated that the X-Gene chips will be at least two-times as power efficient, but has not officially release power consumption numbers for the X-Gene chips under load. However, at idle the X-Gene SoCs will use as little as 500mW and 300mW of power at idle and standby (sleep mode) respectively. The 64-bit quad issue, Out of Order Execution chips are some of the most-powerful ARM processors to date, though they will soon be joined by ARM’s own 64-bit design(s). I think the X-Gene chips are intriquing, and I am excited to see how well they fare in the data center environment running server applications. ARM has handily taken over the mobile space, but it is still relatively new in the server world. Even so, the 64-bit ARM chips by AppliedMicro (X-Gene) and others are the first step towards ARM being a viable option for servers.
According to AppliedMicro, HP Project Moonshot servers with X-Gene SoCs will be available later this year. You can find the press blast below.
