Book description

This IBM® Redbooks® publication introduces the IBM Storwize® V7000 Unified Disk System, a virtualized storage system that consolidates block and file workloads into a single storage system. Advantages include simplicity of management, reduced cost, highly scalable capacity, performance, and high availability. It also offers improved efficiency and flexibility through built-in solid-state drive optimization, thin provisioning, IBM Real-time Compression™,
and nondisruptive migration of data from existing storage. The system can virtualize and reuse existing disk systems, which offers a greater potential return on investment.
