DataCenterVirtualization

What is the future of virtual storage in a Software Defined Data Center (SDDC)? As more and more technology gets moved from hardware to software in the SDDC, I have to wonder which direction virtual storage will go.

If we use networking as an example, the technology has evolved from setting up local virtual switches on each of the hosts to a virtual distributed switch (VDS) model where all the individual host-level virtual switches are abstracted into a single large VDS that spans multiple hosts at the Datacenter level. In this design, the data plane remains local to each VDS, but the management plane is centralized with VMware vCenter Server acting as the control point for all configured VDS instances.

Depending upon what your or somebody else’s definition of a storage hypervisor is, you may or may not be using one or realize it.

If your view of a storage hypervisor is a storage IO optimization technology to address performance and other issues with virtual machines (VMs) and their hypervisors, such as Virsto or ScaleIO along with others, you might be calling those storage hypervisors as opposed to middleware, management tools, drivers, plug-in, shims, accelerators, or optimizers.
