Technical Description

 

 
 

The IBM XIV® Storage System is a next-generation high-end open disk storage system. Part of IBM’s broad spectrum of system storage and SAN offerings, the XIV Storage System is an innovative, enterprise disk system based on a grid of standard, off-the-shelf hardware components. The IBM XIV system employs a storage architecture designed to provide the highest levels of performance, reliability, and functionality combined with unprecedented ease of management and exceptionally low TCO.

The IBM XIV Storage System is designed to deliver consistently high performance through the elimination of hot spots and the full exploitation of system resources. Its ground-breaking architecture provides optimized performance, scalability, and ease of management while harnessing the high capacity and cost benefits of SATA drives.

Outstanding availability and reliability are delivered through a revolutionary redundancy scheme, enabling automated self healing with exceptionally fast rebuild times. Additionally, software functionality including snapshot capability, thin provisioning, and remote mirroring can help to ease provisioning and protect business data from unexpected outages. The IBM XIV Storage System can help customers deploy an information infrastructure that is reliable, versatile and available while offering improvements in storage management, provisioning and improved asset utilization.
