EMC Turns to Flash

Arthur Cole

EMC is embracing flash storage for its high-performance line, both as a means to improve performance and to lower both the capital and operational costs of its systems.


The first system to see solid state flash drives (SSDs) is the Symmetrix DMX-4. The company says it has performance-tested a new generation of single-layer cell (SLC) flash technology, coupled with high-performance controllers, and has determined them to be hardy enough for the demanding read/write environments needed for mission-critical applications.


EMC also reports a significant energy reduction with flash technology. A single flash drive, for example, uses close to 40 percent less energy than a mechanical drive. But it would take an array of 30 or more Fibre Channel drives spinning at 15k to equal the performance of a single flash, which, on a per-transaction basis, results in a power reduction of 98 percent. And response times are reduced to the single millisecond range with flash technology.


The new DMX-4 platform is expected to be available in 73 GB and 146 GB capacities in the next few months.
