StorageMojo is one of the first sites to report about an exciting product that will (probably) be released by Sun soon: the F5100 flash array. It’s a 1U rackmount system that contains 80 flash modules. The main innovation for this system are the flash modules themselves; Sun uses an SO-DIMM socket to connect the flash modules. According to what I’ve heard so far the modules will initially be available with a capacity of 24 GB, with 48 GB versions following later to bring the total capacity of the array to 4TB.

The total I/O performance should easily top 1 million IO’s per second for reads, and it will reach a very significant number of writes per second as well. The modules can be accessed via SAS interfaces. As far as the rest of the hardware is concerned, the fan trays and power supplies are hot-swappable. The flash modules and the “energy storage modules” that provide backup power are not. There are some other limitations; StorageMojo has already found some in the currently available documentation, and I’m sure we’ll see more as the system is officially released.
