Editor:- April 12, 2013 - the RamSan-720 (SLC) and RamSan-820 (MLC) have become the new IBM FlashSystem 720 and 820. See also:- IBM's flash SSD page.


Editor:- October 1, 2012 - IBM today announced it has completed its acquisition of Texas Memory Systems.
manufacturer description
Texas Memory Systems In the past year (written mid 2012) Texas Memory Systems launched 4 different 1U rackmount flash SSD products which set new standards for FC SAN storage performance, density and competitiveness. They use a variety of new architectural techniques which I discussed in articles at the time each product was launched. The models can be summarized as follows:-
  • no single point of failure - MLC or SLC
  • fast / high density:- MLC or SLC

  • At the top of the range - in terms of reliability and flexibility of use - the RamSan-720- a 4 port (FC/IB) 1U rackmount SSD which provides 10TB of usable 2D (FPGA implemented) RAID protected and hot swappable - SLC capacity with 100/25 microseconds R/W latency (with all protections in place) delivering 400K IOPS (4KB), 5GB/s throughput - with no single point of failure (at $20K/TB approx list).
  • The RamSan-710 - a 1U rackmount SSD with 5TB usable SLC flash storage with 2 dual ported 8Gbps FC ports upto 2 40Gbps InfiniBand ports. Throughput is quoted as 5 GB/s - although no IOPS figure was mentioned at press time. The system includes various reliability options- including N+1 batteries to support orderly shutdown and an internal active spare flash card configuration option which provides protection levels beyond RAID.
