Dell’s EqualLogic storage solutions deliver the benefits of consolidated networked storage in a self-managing, iSCSI storage area network that is affordable and easy to use, regardless of scale. By eliminating complex tasks and enabling fast and flexible storage provisioning, these solutions dramatically reduce the costs of storage acquisition and ongoing operations.
Patented page-based volume management enables automatic movement of data while it is in use. This technology provides the foundation for online expansion, automatic configuration and load balancing, performance optimization, and advanced software functionalities — all with continuous access to data. That means no downtime for increasing capacity, moving data between storage tiers, or load balancing storage, and most management tasks are handled by the array, not the administrator. As a result, the EqualLogic PS Series of arrays makes enterprise-class shared-block storage practical for all servers and applications.
With its unique peer storage architecture, the PS Series delivers high performance and availability in a flexible environment with low cost of ownership. Whether you are seeking to consolidate storage, migrate from DAS or NAS, streamline data protection, or expand capacity, the PS Series of proven, self-managing storage arrays will meet the demanding requirements of your business-critical environment.
