Introduction<br />
The Texas Memory Systems <strong>RamSan</strong>® line of solid st<strong>at</strong>e disks (SSDs) has always<br />
domin<strong>at</strong>ed <strong>the</strong> performance end of <strong>the</strong> storage spectrum. Th<strong>at</strong> performance<br />
dominance continues with <strong>the</strong> new Texas Memory Systems Series-7 family. The<br />
<strong>RamSan</strong>-<strong>710</strong> offers up to 5.15 TB of capacity in a 1U chassis th<strong>at</strong> typically draws 280<br />
w<strong>at</strong>ts of power.<br />
FIGURE 1: THE RAMSAN-<strong>710</strong><br />
The <strong>RamSan</strong>-<strong>710</strong> blows away 15K RPM hard disk drive arrays in density, cost, and<br />
reliability while offering stunning performance and power efficiency. This SSD<br />
leverages gener<strong>at</strong>ions of backplane, interface, and reliability experience designed<br />
into <strong>RamSan</strong> solid st<strong>at</strong>e disks (SSD).The <strong>RamSan</strong>-<strong>710</strong> has <strong>the</strong> following key fe<strong>at</strong>ures:<br />
The World's Fastest Storage®: Sustained I/O r<strong>at</strong>es up to 400,000 IOPS for reads<br />
or writes and sustained, random bandwidth up to 5 GB/second.<br />
Next-Gener<strong>at</strong>ion Series-7 Product Family: <strong>RamSan</strong> Series-7 is <strong>the</strong> 7th<br />
gener<strong>at</strong>ion of <strong>the</strong> <strong>RamSan</strong> product family, origin<strong>at</strong>ing from <strong>the</strong> first <strong>RamSan</strong> in<br />
2000. All Series-7 <strong>RamSan</strong> products deliver cost-effective performance and<br />
reliability.<br />
Series-7 Flash Controller: One key to <strong>the</strong> uncompromising performance of<br />
Series-7 products is <strong>the</strong> Series-7 Flash Controller. Based on high-performance<br />
Xilinx FPGAs and a PowerPC processor, <strong>the</strong> Series-7 Flash Controller is fieldupgradable,<br />
ensuring th<strong>at</strong> TMS customers will always have <strong>the</strong> best<br />
performance and l<strong>at</strong>est fe<strong>at</strong>ures.<br />
Variable Stripe RAID (VSR): VSR is a p<strong>at</strong>ented technology only available to<br />
TMS customers th<strong>at</strong> drastically reduces wasted planes. If a plane fails, VSR<br />
autom<strong>at</strong>ically rebuilds and reloc<strong>at</strong>es <strong>the</strong> d<strong>at</strong>a from th<strong>at</strong> plane. It <strong>the</strong>n allows<br />
d<strong>at</strong>a to be rewritten to <strong>the</strong> area, dynamically altering <strong>the</strong> size of <strong>the</strong> stripe to<br />
avoid <strong>the</strong> failed plane. Under traditional RAID schemes, <strong>the</strong> entire stripe would<br />
have been unusable and all its remaining good planes would have been lost.<br />
8 Gbit Fibre Channel: The <strong>RamSan</strong>-<strong>710</strong> comes with new dual ported 8 Gbit Fibre<br />
Channel controllers.<br />
QDR InfiniBand: The <strong>RamSan</strong>-<strong>710</strong> can be equipped with up to two QDR<br />
InfiniBand ports.<br />
