IBM Storwize V7000, Spectrum Virtualize, HyperSwap, and VMware Implementation

Book Description

IBM® Spectrum Virtualize Software Version 7.5 provides software-defined storage capabilities across various platforms, including IBM SAN Volume Controller, IBM Storwize® V7000, Storwize V7000 (Unified), Storwize V5000, Storwize V3700, and Storwize V3500. These offerings help clients reduce the complexities and cost of managing their storage in the following ways:

  • Centralizing management of storage volumes to enable administrators to manage storage volumes from a single point

  • Improving utilization of storage capacity with virtual volumes to enable businesses to tap into previously unused disk capacity

  • Avoiding downtime for backups, maintenance, and upgrades

  • Performing data migration without disruption to applications

  • Enabling all storage devices to be organized into storage pools from which virtual volumes, whether standard, compressed, or thin-provisioned, are created with the characteristics that you want

  • Delivering automation of storage management with SmartCloud Virtual Storage Center, IBM Tivoli® Storage Productivity Center (as applicable by platform), and IBM Tivoli Storage FlashCopy® Manager (as applicable by platform)

  • Increasing the performance efficiency of storage pools with IBM Easy Tier®

  • Restoring data access quickly with near and remote copy capabilities across Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), and IP networks


  • In this IBM Redbooks® publication, which is aimed at storage administrators and technical professionals, we describe the IBM HyperSwap® capability in IBM Spectrum™ Virtualize Software V7.5. HyperSwap delivers high availability (HA) and disaster recovery (DR) in one solution and reuses capital investments to achieve a range of recovery and management options that are transparent to host operations.

    This book describes how you can use HyperSwap with VMware to create an environment that can withstand robust workloads.
