Server interconnects: Intel talks, shows AMD products
Intel plans to equip future server processors with a high-performance interface that is ideal for HPC clusters or closely packed micro server. The semiconductor world leader draws on, among other know-how, patents and developers, which he has incorporated with the acquisition of Fulcrum, the division of Qlogic InfiniBand interconnect and the division of Cray. About specific products or dates yet but said nothing Intel can.
AMD has purchased as practical, namely, the startup company SeaMicro. She announced - to the new "Fabric Compute System" SM15000 and a matching storage system Freedom Fabric Storage with up to 5 petabytes of capacity - not coincidentally on the eve of the Intel Developer Forum IDF. The latter is the real novelty, the SeaMicro SM15000 announced CEO and general manager of AMD's Andrew Feldman in June on the AFDS 2012th
Now, there is more concrete information for SM15000. In the foreground are new server Opterons with eight Bulldozer cores of Piledriver generation - that is with Seoul processors for the C32 version. On the press photo of the SM15000-OP is still the 35-watt Opteron 4256 EE predecessor (Valencia) to see with eight cores also the first generation of Bulldozer, which is clocked at 1.6 GHz. He binds up to 64 GB of RAM in the form of four 16-gigabyte memory modules - that is yet rarely ECC RDIMMs in SO-DIMM format.
The SeaMicro specialty are the fabric chips: The company has developed a high-performance interconnect, which is based on PCI Express method. The aggregate data transfer rate of a complete 10-U system with 64 blades is 1.28 terabits s / About this "Fabric Freedom", the network adapters are connected, either 16 10-Gigaibt Ethernet ports and 64 1-Gigabit Ethernet ports. In addition, fit into 64 2.5-inch hard drives or SSDs. Than 3.2 kW average power called SeaMicro. But you can install depending on the desired redundancy for up to ten 1100-watt power supplies, at least five are needed. The maximum intake called SeaMicro 35 degrees Celsius.
Furthermore, AMD sold via SeaMicro and Intel processors. As an alternative to the Opteron blades, there are those with the single-socket Xeon E3-1265L V2 (Ivy Bridge Quad-Core 2.5 GHz, 45 watts) or E3-1260L (Sandy Bridge quad-core 2.4 GHz , 45 watts) that connect a maximum of 32 GB of ECC RAM. Finally SeaMicro continues to atom, namely the dual-core N570 (1.66 GHz). Each of which binds to only 4 GB of RAM without ECC error protection, for 256 pieces, with 512 cores and 1,024 threads fit in the 10-U rack. The Opterons make 512 Bulldozer cores prepared the Xeon cores of 256 and 512 threads. The Sandy Bridge version of the SM15000 can buy now, the others will be available from November.
The new storage systems are supposed MicroServer suitable for "big data" applications, such as Hadoop. Three different storage modules are available, each of which can be up to 16 to connect to a SM15000. The FS 5084-L aims at maximum capacity and brings 84 hard drives on 5 rack under HE - with 4-TB SATA drives are theoretically 336 terabytes per module, or 5.3 per PByte SM15000 possible. FS 2012 and FS-L 2024-L are each 2U high, the former is for twelve 3.5-inch and the latter is designed for 24 2.5-inch drives. Each module has two SAS controllers that are externally connected via three ports x4 (SAS 6G) with SM15000.
