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.
