Texas Memory Systems RamSan-70 Beats Fusion-io and Virident in New Independent Test
Swiss National Supercomputing Centre's comparison ofPCIe SLC Flash Cards finds the 'Gorilla' delivers highest IOPS value ever measured by lab
The September 2011 CSCS report entitled "Comparison of PCIe SLC Flash cards" by analysts Hussein N. El-Harake and Thomas Schoenemeyer, summarises the benchmark testing performed on the RamSan-70, which replicates previous testing on the performance of cards built by Fusion-io and Virident. Using two open-source benchmark tests to perform bandwidth and IOPS measurements, the tests, carried out in August 2011, proved that the RamSan-70's performance compared to SATA drives or other PCIe devices is "outstanding."
"The RamSan-70 provided by far the best IOPS result we have ever measured at CSCS with a peak of more than 300,000 IOPS at 4K for (the) FIO (benchmark test), which is consistent to the expected value," reads the report. "(It) delivers a very stable IO bandwidth over a wide range of block sizes, which is a clear differentiator to the (Fusion-io and Virident) cards tested in the previous study."
The RamSan-70 is available in two configurations, starting at 450 GB of usable (SLC) NAND Flash capacity, which was used by CSCS in its independent testing. Adding a mezzanine card, another 450 GB for a total of 900 GB of usable Flash capacity, delivers 600,000 random read IOPS. The 900 GB RamSan-70 is the highest capacity SLC-based PCIe Flash card on the market and performs at twice the speed of the tested version that set the lab's performance record. Users can start with 450 GB and 300,000 IOPS board and add the mezzanine card later when more capacity and performance is needed.
The RamSan-70 handles all Flash management functions without impacting the host CPU. It incorporates patented Variable Stripe RAID(TM) (VSR(TM) ) technology that increases MTBF and endurance. When a Flash device fails on a Virident unit, the Flash device must be replaced. When a Flash device fails on the RamSan-70, VSR automatically bypasses the failing device without requiring any downtime. Other RamSan-70 features include proprietary enterprise-level reliability features which include chip-level RAID and an advanced ECC algorithm that corrects more errors than required by the manufacturer.
The Series-7 Flash Controller (TM) is field-upgradable, ensuring that Texas Memory Systems customers will always have the best performance and latest features. The Series-7 Flash Controller, combined with Toshiba 32nm SLC Flash, provides the enterprise-level performance and reliability customers expect from The World's Best Flash Storage(TM) .
"It wouldn't surprise anyone if they heard me say that when speed and performance are critical to the success of a company's business, there is no better solution on the market today than the RamSan-70," said Holly Frost, CEO of Texas Memory Systems. "But to have those claims backed up by independent testing by a respected organisation like the Swiss National Supercomputing Centre, we are able to validate the hard work we've undertaken to achieve our results. We went head-to-head against Fusion-io and Virident and we came out on top. Add in our exceptional service, and there's no reason to turn to anyone other than Texas Memory Systems."
Designed specifically for the OEM market, the RamSan-70 is the ideal in-server storage solution for data warehousing, enterprise resource planning (ERP), sophisticated data acquisition, scientific computing, and web content.
