SAN Storage

A Storage Area Network (SAN) is a high-speed network that provides multiple servers access to consolidated pools of shared, block-level storage.

Who uses SAN Storage?

Organizations of all sizes use Storage Area Networks (SANs) to increase storage utilization rates (i.e. multiple hosts accessing the storage devices), improve application performance and availability, and to heighten security and data protection capabilities. By presenting storage devices to hosts such that they appear to be locally attached storage, SANs also facilitate the presentation of storage to users.

Why should I consider SAN Storage?

SANs work by providing block-level, high-speed network access to storage for multiple hosts. By interconnecting hosts, switches, controllers and storage, and using a variety of high-speed, high-reliability communications protocols, SANs can consolidate previous “islands” of storage.

Benefits of SAN Storage

SANs deliver highly reliable, highly scalable block-level storage solutions, accessible by many hosts. Increased storage utilization rates often drive down storage cost of ownership, while multiple security and reliability features ensure mission critical data is always protected and available. These enterprise-class features make SANs the storage solution of choice for today’s data-driven organizations.
