Similarly, SANs have become the Consolidation in the data center has typically meant improved de facto standard for corporations that have recognized the operations and reduced costs (e.g., benefits of blade servers or manageability, availability, and cost savings associated with virtualization). These same benefits are extended to I/O as data shared storage. The most prominent storage solution for Linux is centers implement a new consolidated network technology for Fibre Channel, according to the July 2007 IDC Worldwide Disk data and storage, called “converged networking.” Converged Storage (see Figure 1). As corporate data centers standardize networking combines existing Local Area Networks (LANs) and on Linux, they insist on “enterprise-class” SAN connectivity SANs into a single high performance 10Gb/s Ethernet framework solutions and supporting system software that can meet their that intelligently connects every server, network and storage reliability, scalability and manageability requirements.
