Software-Defined Storage is the Missing Link in the Software-Defined Data Center
At this year’s VMworld 2012, held in San Francisco, the “software-defined data center” was a major topic. The idea is appealing: make the entire IT infrastructure completely fluid so that all resources–compute, network, and storage–can be quickly and easily allocated or reclaimed to meet dynamic business requirements, thereby extending the flexibility and cost savings benefits ...
The Missing Link in the Software-Defined Data Center
Lately, there has been a lot of talk about the software-defined data center. By increasing management flexibility and lowering server costs significantly through increased utilization of existing CPU and memory resources, server virtualization brought significant benefits to IT organizations.

The Importance of Snapshots in Virtualized Environments
Snapshot technologies have been around for a long time. Essentially, they let you quickly make online, disk-based copies of selected data sets that are easily accessed. With virtual computing becoming a mainstream deployment platform, these technologies are taking on a heightened importance. When we refer to “snapshot technology”, there are two objects we have in ...

Server hypervisors are allowing us to wring a lot more out of our server resources, but the storage in virtual environments is being used even less efficiently than it was when it was attached only to physical servers. The goal of a storage hypervisor is ...
