    IBM XIV Product Brief

    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.

    The XIV Storage System uses nodes of Intel-based server boards and captive disk storage with Ethernet switching for interconnect to provide a grid-based storage system. The nodes are identical from storage and processing capability but some nodes may have additional host bus adapters installed providing the external interfaces for attachment to a SAN or direct to servers. The nodes are called Data Modules (DM) and contain up to 12 NL-SAS disks that are 7,200 RPM. An XIV system can have up to 15 Data Modules (nodes). The interconnection between the Data Modules is accomplished with dual InfiniBand switches to provide redundancy. The redundant switches are 20Gb/s and are integrated in the cabinet with the Data Modules. Because every node is a Data Module, any to any connectivity is required. UPS’s are incorporated into the XIV to provide both availability and data integrity. Redundant N+1 UPS’s are supplied as part of the system.

    IBM Hyper-Scale manages multiple XIV systems as a single system and enables transparent migration of volumes between systems.
