Webinar: Making Your Way Through The Storage Virtualization Maze
Shared storage has new life thanks to virtualization. Features like virtual machine migration essentially requires a shared storage array to work. Shared storage, however, also brings a fair amount of complexity and the dreaded I/O blender. Suddenly storage arrays are…
ChalkTalk Video: Is More Flash or Spindles the only Answer to the VMware I/O Blender?
The VMware I/O blender is caused by multiple virtual machines generating random I/O at the hypervisor layer that bottlenecks storage systems. Adding more flash or spindles seems like the quick fix to this problem. The noise at the I/O blender…

Briefing Note: Stopping Virtualization’s Double Tax
Virtualized Windows applications suffer from two I/O taxes. First, there is the tax of the I/O blender caused by mixing dozens of VMs on a single server, and then connecting multiple servers to a shared storage array that creates a…

How Storage Vendors Integrate VVols
VVols simplifies the process of setting up and managing storage to support VMs by enabling VMware administrators and users to create specific storage policies. But under the covers VMware leaves the implementation of VVols to the storage array vendor. In…
Choosing The Right Flash Storage Architecture For Virtual Data Centers
When effectively implemented, flash storage technologies can help remedy storage IO contention issues and deliver a performance benefit to virtualized applications. It is important, however, for IT planners to find ways of augmenting virtual machine (VM) performance without discarding their…
