According to StorageNewsletter.com the Solid State Storage Initiative (SSSI) of the Storage Networking Industry Association (SNIA) has released the Client Solid State Storage (SSS) Performance Test Specification (PTS) to the public. The Client PTS comprises a suite of tests and test methodologies necessary to enable comparative testing of individual SSS client device performance. The SSS PTS itself includes a Reference Test Platform (RTP) that ensures the comparison of results on a true 'apples-to-apples' basis across multiple testers,

The Serial ATA International Organization (SATA-IO) has announced a new PCI Express (PCIe)-based interconnect specification designed to boost interface throughput of solid state drive (SSD) technology from 6GB/sec to 8Gb/sec and 16Gb/sec writes Lucas Mearian in Computerworld. The new SATA Express specification is said to protect investments in current SATA and PCIe products because it's a hybrid of both and still looks like SATA to the host system. The specification will define new device and motherboard connectors that will support both new SATA Express and current SATA devices, Mearian notes.

The Sun Blade X6275 M2 server module cluster configured with 8 x Sun Blade X6275 M2 server modules, each with 4 Intel Xeon X5670 2.93 GHz processors, turbo enabled 96 GB memory 1333 MHz
2 x 24 GB SATA-based Sun Flash Modules 2 x QDR InfiniBand Host Channel Adapter and Sun Datacenter InfiniBand Switch IB-36 delivered a performance advantage over IBM, Cray and SGI solutions in the ANSYS FLUENT 12 fluid dynamics application benchmark test suite, outperforming the best posted results by as much as 42%. This mark was set without modifications to the Oracle Enterprise Linux 5.5 running in the benchmark, as reported in a recent Sun BestPerf posting. The Sun Blade X6275 M2 server module demonstrated up to 76% performance improvement over the previous generation Sun Blade X6275 server module, the posting notes.

By hiding the write latency of disks and thereby enabling the use of economical, high-capacity drives, Logzilla, a key component of the ZFS Hybrid Storage Pool, can accelerate synchronous writes, blogger Adam Leventhal observes, conceding at the same time the role played by the fast SAS and SATA SSDs from STEC in the Sun Storage 7000 series. He adds that using SAS-attached SSDs is a simpler and more reliable, though slower, clustering solution than the traditional PCI-attached DRAM device, however.
