The Dell™ EqualLogic™ PS4000 is designed to address the needs of remote office and small/medium business storage deployments. It is designed with the same innovative EqualLogic virtualized architecture and the full software feature set as previous generations. However, it offers an affordable entry point for smaller PS Series configurations so remote offices can get the benefits of data center-class IT solutions such as consolidation and virtualization.
