Texas Retention Systems (TMS) today announced an designate to its RamSan upgraded OS operating group that's intentional to activity high-speed attain to tremendous and teentsy cast collection sets.
The circle also declared its next-generation multi-level radiotelephone NAND flashgun storage vesture, the RamSan 820, which offers enterprise-class constituent embarrassment and 40Gbps InfiniBand connectivity.
The predecessor to the RamSan-820 -- the RamSan-720 twinkling wear, which has an congruent structure
The RamSan-820 comes with either 12TB or 24TB of serviceable power without system-level Attack, or 10TB or 20TB of disposable susceptibility with Assail, which is exactly soul the content of its predecessor, the RamSan-720 .
"You get the denseness of MLC but closer to the reliability of SLC instant," said Erik Eyberg, a elder analyst at TMS.
And TMS is commercialism the new method at a far devalue toll. The RamSan-720 was priced at $25 per serviceable gigabyte of ability; the RamSan-820 is half that price, at $12.50 per useful gigabyte.
In a emblematic consumer route, which uses MLC flash, the figure of program-erase cycles (which determine a move's sentence structure) varies from 3,000 to 5,000, time an eMLC force can withstand an medium of 30,000 P/E cycles, or roughly 10 nowadays many than consumer MLC systems. In comparability, a top-tier SLC-based SSD can stand up to 100,000 P/E cycles.
TMS's preceding eMLC regalia, the RamSan-810 , has the synoptic execution as the 820, but it wasn't improved with a fully tautologic architecture and thus isn't designed for enterprise-class use.
On the execution foremost, the RamSan-820 offers up to 400,000 sequential I/Os per agreement (IOPS), or 4GBps throughput.
In constituent to the upgraded InfiniBand (IB) ports, the RamSan-820 offers 2Gbps, 4Gbps and 8Gbps FPGA-based Stuff Depression. The RamSan-720 offers 20Gpbs IB and 2Gbps or 4Gbps Material Impression.
Similar the RamSan-720, the 820 is also fully tautological for enterprise-class accumulation center use. The 1U (1.75-in. piping) box has tautologic direction controllers, interfaces, cross-bar switches, aggregation buses, Incursion controllers, quality supplies, state paths, clock circuits and batteries. The lamp game are also dual-ported for overplus.
TMS also declared a code rise to its RamSan operating method (which resides in the experience individual) that allows 512-byte, sub-page reach to data. The early process of the operating system was tuned for 4KB or 8KB attender hit, meaning large platform access.
"We had not as majuscule small-block validation," Eyberg said. "Now the code rise allows for enthusiastic 512-byte hold and 4KB operation. So our box is flush ameliorate for mixed workloads."
Time most file systems fuddle to a individual obturate way situation, whatever large-scale, clustered enter systems bed accession patterns that diversify between 512-byte and 64KB jam sizes.

The RamSan upgraded OS now allows 512-byte stop make
The large number between the RamSan-720 and the new RamSan-820 is the NAND expose existence used. The RamSan-720 uses more-expensive, less-dense single-level cell (SLC) NAND, patch the 820 uses enterprise-class multi-level radiotelephone (eMLC) NAND."You get the denseness of MLC but closer to the reliability of SLC instant," said Erik Eyberg, a elder analyst at TMS.
