Tilera Corporation and Quanta Computer Inc. today unveiled the world’s most power efficient and highest compute density server, codenamed S2Q. The S2Q server, targeted specifically to tackle today’s cloud computing workloads, was designed in collaboration with cloud datacenter providers, end customers and software partners. It is targeted at large-scale datacenters running high performance web, database, hosting, and finance applications.
The new server is based on the Tilera’s TilePro64 processor series. This latest generation processor features 64 identical processor cores (tiles) interconnected with Tilera’s iMesh™ on-chip network. Each tile is a complete full-featured processor, including integrated L1 & L2 cache and a non-blocking switch that connects the tile into the mesh. The TILEPro family incorporates Tilera’s DDC™ technology (Dynamic Distributed Cache) that accelerates coherent cache performance by a factor of two compared with other multicores. As with all Tilera processors, each tile can independently run a full operating system, or multiple tiles taken together can run a multi-processing OS like SMP Linux.
The TILEPro64 processor slashes board real estate and system cost by integrating a complete set of memory and I/O controllers, thus eliminating the need for an external northbridge or southbridge. It delivers scalable performance, power efficiency and low processing latency in an extremely compact footprint.
The S2Q server uses so-called “twin” half-width server boards, with 4 dual system boards in a 2U rack chasis. Each twin mobo in the Quanta SQ2 server has two of the TilePro64 processors on it, plus eight DDR2 memory slots per processor and will support 4 GB DDR2 memory sticks running at 667 MHz (with ECC), for a maximum capacity of 64 GB per module. The TilePro64 processors act as a single node, meaning there is not symmetric multiprocessing linking their cache or main memories, so each node has 64 cores and up to 32 GB of memory.
The Quanta system board has four Gigabit Ethernet ports, four 10 Gigabit Ethernet ports with SFP+ connectors and two 10/100 Mbit Ethernet ports for IMPI 2.0 remote management and two 10/100 Mbit Ethernet ports for plugging in management consoles. Each chassis has 24 disk drives (SATA or SAS) in the front.
The Quanta QS2 design allows for 10,752 cores to be crammed into a single 42U rack, and use less than 8 kilowatts of power.
