  • 1. P R O D U C T I N D E P T H Midrange Redefined – the IBM Storwize V7000 November 2010 The marketplace for mid-range storage arrays has long been a battlefield with victory too often declared solely on the basis of low price and high volume. Such is small wonder, given that the cost and demand for storage has long increased price sensitivity among customers. But such victories have too often been pyrrhic for the storage administrator on whose backs they have been won. Thosestorage administrators must bear the burden of the very things that let vendors compete onprice - minimal storage features, uncertain performance, aging architectures, and limitedflexibility.We’ve long observed that this trend in price-driven capability-compromise is poised to change,despite the resistance of some vendors. A handful of vendors long ago heard the call forchange. Across the board, their innovations under the banner of next generation storage haveinevitably been built upon virtualization – typically homogeneous virtualization that can beturned to the purpose of aggregating disks in new ways, distributing data across more disks toenhance performance and management, and masking underlying complexity while aligningstorage capabilities to the needs of applications. Without a doubt, there is only growingdemand for next generation storage today – consolidation, virtualization, more data, andgrowing workloads simply demand next generation capabilities.So it is little surprise that IBM has recently turned their attention to building next generationcapabilities within a mid-range storage array. But they’ve done it starting with a secret weapon– the most widely adopted and successful heterogeneous virtualization engine in the market,their SAN Volume Controller (SVC). For our part, we can think of few better places to start. Thecapabilities of this new platform suggest that the battle over price may well shift to be instead abattle over right-priced capability, or in other words, one of total value. In this product indepth, we’ll take a look at this platform – the IBM Storwize V7000 Array.The Legacy of Mid-range Storage complexity in storage products, limitations in storage system performance and features,There are few among storage practitioners intolerable impacts during storagearound the world who can read this profile maintenance and migrations, and more.and not immediately relate to a story ofstorage pain.
