Last week, Texas Memory Systems published preliminary SPC-1 test results for its latest SSD-based SAN, the RamSan-630. In so doing, it firmly signaled the beginning of the end for spinning disk in performance-hungry high-end transactional storage applications. It's also made strides toward closing the cost-per-gigabyte gap between traditional disk and solid-state drives.
It should come as no surprise to anyone familiar with the performance characteristics of flash storage that an SSD SAN can handily beat a far larger and more expensive non-flash SAN. The interesting thing is to see exactly how well and how inexpensively it can do the job.
In TMS's case, it presented test results that saw a single RamSan-630 kick out 400,503 SPC-1 IOPS at a total as-tested list price of $419,292. That works out to an incredibly cheap $1.05 per SPC-1 IOPS.
It also easily outperforms the previous SPC-1 record holder -- a combination of two disk-based IBM DS8700s running behind a six-node IBM SVC (SAN Volume Controller) cluster. That test saw the overall system kick out 380,489 SPC-1 IOPS at a heart-stopping street price of over $7 million. In the end, the cost per SPC-1 IOPS worked out to $18.83 -- nearly 18 times as expensive as TMS's flash-based entry.
