Texas Memory Systems SSDs: 1 Million IOPS, 10 GB/s Bandwidth - RamSan-630 (3U) 10 TB Flash SSD Speicherarray mit neuen QDR InfiniBand Interface Cards

London, Starnberg, 4. Okt. 2010 – Texas Memory Systems, Inc. hat sein RamSan-630 SSD-Storagesystem mit neuen IB-381 InfiniBand interface cards aufgerüstet...

Damit stehen bis zu 140 TB mit quasi unlimitierter Bandbreite speziell für HPC (High Performance Computing) - Applikationen zu Verfügung. Interessant ist technologiebedingt das I/O per Watt – Verhältnis; es werden laut Hersteller bei 14 Mio. IOPS rund 7.000 Watt verbraucht; ein Wert, der mit konventionellen Festplatten nicht erreicht werden kann. Mehr Details finden Sie in den nachfolgenden Originalangaben des US-Herstellers...  

“The IB-381 augments the RamSan-630’s available Fibre Channel interfaces, giving users greater flexibility in connecting to high-performance storage networks. The IB-381 supports InfiniBand SCSI RDMA Protocol (SRP) over two Quad Small Formfactor Pluggable (QSFP) connectors.  The use of a Mellanox ConnectX-2 chip ensures compatibility with most other Quad Data Rate (QDR) InfiniBand devices. The IB-381 also employs a dedicated 1-GHz PowerPC processor and a powerful Xilinx Virtex-6 Field Programmable Gate Array (FPGA) to obtain the utmost in I/O performance. The RamSan-630 can be configured with 5 dual-channel IB-381 cards for a total of ten links operating at 1 Million IOPS and 10 GB/second.
 
The typical HPC cluster often consists of hundreds or thousands of individual computers. Such a computing cluster demands the utmost in performance from attached storage devices, but at a cost-effective price.  Users must perform a balancing act between the resources dedicated to CPU power, RAM capacity, external storage, and network connectivity. While HPC users have typically focused on increasing RAM capacity, expected dramatic price reductions for Flash-based Enterprise storage should facilitate a move toward a tiered storage architecture. The RamSan-630, with multiple InfiniBand cards, can be an effective piece of such a tiered architecture. Compared to other storage options, it provides a dramatic improvement in performance, capacity, size, and cost.
 
Installed in a high-performance network, the RamSan-630 provides centralised storage that is simultaneously accessible by many different computers.  The RamSan-6300 system (a single rack of 14 RamSan-630 systems) offers 140 TB of storage capacity with virtually unlimited bandwidth. Regardless of the access mode (random, sequential, reads,  writes), the RamSan-6300 provides 140 QDR InfiniBand ports, 140 GB/s of bandwidth, and 14 Million IOPS, while still dissipating only 7000 Watts.
