Object-based storage allows users to tame ballooning data stores
This article is part of the December 2011 issue of IT in Europe
With the rapid growth of unstructured data in corporate systems, technologies that can effectively store large amounts of discrete files have begun to emerge. Scale-out and internal cloud systems are chief among them, but often under the hood of these approaches is an entirely different way of handling data: object-based storage. To date, the file system has been king. It provides some form of central database that is referred to when an application requests data. The database typically contains information about the file, including directory (tree) information, physical (hard drive) location of related blocks, security and access restrictions. It’s a hierarchical, location-based method of storing information about files. As data stores grow, traditional file systems soon become very complex. And they’re limited in the number of files they can deal with. One response to ballooning numbers of files is to partition file systems into volumes. This helps resolve latency issues but adds management overheads as data becomes separated ...

Don't let capacity concerns or virtualized servers bog down the performance of your storage systems. Here are 10 ways to pump up the performance of your storage arrays and networks
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.
