The HP StorageWorks Enterprise File Services Clustered Gateway delivers superior file serving performance that allows you scale your file serving performance in a linear fashion as nodes are added. In the event of a node failure, all file serving is failed over to the remaining nodes and complete session state is maintained with full data and cache coherency. The foundation of the HP StorageWorks Clustered File System is an architecture that is fully symmetrical meaning all nodes see the entire file system which means there are no hot-spots. This solution has been tested and is being used in a wide variety of customer environments. The solution is built with industry standard components and not proprietary H/W and software so you can leverage your existing SAN infrastructure. The solution is scalable which means that you can purchase only the file serving capability you require and add nodes as you need them.
