Rambus is already looking beyond the conventional DDR4 paradigm to extend main memoryhttp://community.arm.com/community/arm-partner-directory/partner-rambus/blog/2015/03/31/gigabyte-launches-arm-powered-mp30-ar0 Gigabyte recently launched its ARM-powered MP30-AR0 Server on a Chip at WHD.global 2015 in Germany. “[It] is built around the AppliedMicro X-Gene under the ARMv8-A architecture,” reports Anandtech’s Ian Cutress. “The MP30-AR0 uses the 45W X-Gene1, a 40nm 8-core solution running at 2.4 GHz using pairs of cores shared L2 cache with an overriding 8MB L3 cache.” According to Cutress, the system offers quad channel DDR3 with ECC, exploiting two DIMMs per channel for a total of 128GB. Two 10GbE SFP+ ports are included, along with two RJ-45 1 GbE ports from a Marvell 88E1512 controller. Meanwhile, four SATA 6 Gbps ports are part of the SoC, along with two PCIe 3.0 x8 slots in an x16 form factor. As Cutress confirms, the cloud-oriented MP30-AR0 is compliant with both ARM Server Base System Architecture (SBSA) and Server Base Root Requirements (SBBR) standards. “The motherboard/SoC system will also be available in a 1U server rackmount (the R120-P30) with four hotswappable bays and a single PCIe riser card,” he added. Loren Shalinsky, a Strategic Development Director at Rambus, says Gigabyte is clearly “maxing out memory capabilities” on the (first-gen) X-Gene1. “Unsurprisingly, AppliedMicro is already sampling the X-Gene2, which supports both DDR3 and DDR4,” Shalinsky told Rambus Press. “Based on a recent HotChips presentation, we know that the X-Gene2 maintains four channels of memory. It also seems as if multiple SKUs will be offered – ranging from 2.4GHz to 2.8GHz, and from 8 to 16 cores. I would expect that as companies push their way up in performance, they will want to migrate to the higher performance provided by DDR4.” Indeed, DDR4 memory delivers a 40-50 percent increase in bandwidth, along with a 35 percent reduction in power consumption compared to DDR3 memory (currently in servers). In addition, internal data transfers are faster with DDR4, while in-memory applications such as databases - where a significant amount of processing takes place in DRAM - are expected to benefit as well. It should be noted that Rambus is already looking beyond the conventional DDR4 paradigm to extend main memory, with techniques such as near ground signaling, module threading and dynamic point-to-point. |
