Texas Memory Systems unveils the baddest monster with 100Tb,60GB/s and 5 million sustained IOPS

El Reg found the monster they’ve been looking for but I’m sure there’s someone else looking to kick some asses yet again.
These are huge numbers, achieved by a scale-out approach of clustering twenty RamSan-620 flash SSDs into a single entity, taking up an entire 40U rack. It might help to think of it as a 100TB SAN comprised of twenty 5TB storage units.
The flash is single-level cell NAND. The 6200 supports 40 – 160 4Gbit/s Fibre Channel links or 20 – 80 10Gbit/s (quad data rate) InfiniBand lines. Divide these numbers by 20 to get the per-RamSan-620 port counts.
TMS says that, at the board level, each set of flash chips is organised as a RAID unit, preventing any single chip failure from corrupting data. At the system level, each RamSan-620 allows you to designate one of the cards inside the system as an active-spare. If one of the cards experiences a failure that degrades its RAID protection, its data is transferred to the hot-spare. The failed card is then rendered inactive and can be replaced.
