So whats the story? Back in 2010 IBM released the Storwize V7000 and subsequently the Storwize V7000 Unified. The IBM Storwize V7000 is IBMs next generation mid-range storage Virtualization platform. The platform has been built utilising many features from IBMs best of breed solutions including SVC, DS8000 and XIV. The features list is huge and my favourites include Easy Tier, the Dynamic Migration capabilities, the External Storage Subsystem Virtualization capabilities (these are not vendor limited - V6.3 Supported Hardware List, Device Driver, Firmware and Recommended Software Levels for IBM Storwize V7000) VAAI integration, vCenter integration and Clustered Systems. In a sentence it's a solid mid-range storage subsystem containing many features you would only expect to see on an enterprise level storage subsystem.
Data migration from an SVC presenting a DS3k, DS4k & DS5k to a V7000. It looks simple doesn't it? However I recently came across a scenario with an environment running old 4F2 SVC nodes and planned to migrate all data under the SVC on DS3k, DS4k and DS5k storage onto a V7000. This presented a problem in that the V7000 can only be presented as a host to an SVC running 5.1.0.8 and above - V5.1.x - Supported Hardware List, Device Driver and Firmware Levels for IBM SVC A quick check over the Node and UPS Interoperability Matrix for SVC shows that the 4F2s are only compatible with SVC code level 4.3.x.
