Shared storage model faces challenges from virtual servers
This article is part of the December 2011 issue of IT in Europe
The landscape of computing is changing rapidly, largely driven by the move towards virtual servers, and that’s bringing change to storage too. Perhaps mere use of the word “change” understates what’s happening here. The advent of server virtualisation, led by the juggernaut that is VMware, has really stirred up the entire IT environment and could bring seismic shifts for storage. In a relatively short space of time -- say, four or five years -- the needs of virtualisation have helped consolidate the traditional storage array and then have moved swiftly on to sow the seeds of its downfall. Once upon a time, the world was a simple server-centric one. Applications ran on physical servers, and if they were important applications, they had their own dedicated compute resources. Storage was directly attached and all lived in one tin box. Then came server virtualisation. The logical business of a server application was liberated from its former physical surroundings, and many servers could run in one physical machine. This development ...

VMware’s latest releases suggest it has serious intentions about encroaching on storage vendors’ turf, which might be a wakeup call for the data storage industry.
If a tech is judged by the products that crop up around it and the techs it spawns, then it’s hard to argue that solid-state storage hasn’t reached a certain level of maturity.
Virtual servers and storage systems don’t have to exist in separate worlds; new tools and plug-ins provide single-console management of both virtual servers and storage.
