EMC continues to make incremental improvements to its DMX architecture by delivering tangible, tactical benefits to customers. The inclusion of flash-based devices goes beyond that and is an innovation which will likely set off a chain reaction in the industry. Storage organizations should analyze which data sets are candidates for SSD and apply the technology but only where the economics are compelling to business lines. EMC's imprimatur has been stamped on thin provisioning at the high end of the storage marketplace. On balance customers with large amounts of DMX storage will be well served with in-box tiering that accommodates tiers 0, 1 and higher. Customers with a more diverse base of installed storage assets should continue to investigate virtualization engines from EMC and others as part of their strategy.
