The IBM XIV Storage System is an enterprise storage system targeted for usage in open systems environments as a block storage system with either SAN or direct attachment. The XIV is based on a grid of standard servers with storage directly attached and executing the XIV system software to provide a scalable, high-performance storage solution. Multiple XIV systems can be managed and data migrated between them with IBM Hyper-Scale Manager.
IBM Spectrum Accelerate is the XIV software that can be installed on virtual machines to provide storage functionality using commodity servers and storage. All software features of the XIV are available with Accelerate.
The XIV Storage System from IBM provides block storage for open systems which IBM targets at higher-end enterprises. Unlike the DS5000 or N-Series lines of storage also offered by IBM, the XIV is developed by IBM resulting from the acquisition of the product and development team. With the focus on the higher-end enterprise, the XIV Storage System has availability, scaling, and advanced features expected by customers in that market.
