The 64 TB Flash Memory Tower by Texas Memory

At the Siggraph convention in Los Angeles, Texas Memory Systems is showing off a massive rack tower with 64 TB of high-speed flash memory.  The rack can perform 800,000 input/output instructions per second and runs on just 2.5 kilowatts of power.  Total bandwidth on this beast is 12 GB/s.

The rack’s construction is actually quite simple.  Eight RamSan-500 units are stacked in the rack and those do 100,000 IOPS and 1.5 GB/sec each.  Each RamSan box has 16 to 64 gigabytes of DDR cache memory to buffer the flash RAM.  The flash modules are stored in pop-out “drives” and are in a redundant array.  In fact, just before we walked up to the booth, another attendee pulled out one of the drives without warning.  The company spokesman said all the data was still safe, but added that it would take approximately 10 – 15 minutes to rebuild the array.
