The OpenStack Summit this week continued to fan the flames of the software-defined data center. The software-defined data center is just a term for replacing traditional data center hardware functionality with the same features implemented in software, running on commodity x86 servers. While software-defined approaches to data center features are at least nominally less expensive than their hardware counterparts the real promise in the approach is flexibility and management ease with high levels of integration. Reconfiguring a network to support the security requirements of a new application is now just a function of software and APIs. Expanding storage is just simply adding another node with more storage attached, and the cluster compensates automatically. Even things like firewall rules and load balancer configurations can now be stored as templates along with the applications, to be provisioned in minutes.

VMware has announced that they have entered in a definitive agreement to acquire Virsto, a vendor who offers a “storage hypervisor” for virtualized environments. This is likely to factor significantly into VMware’s SDDC strategies.
Without question the answer must be “yes”.
Just what are storage hypervisors? There are several companies that claim to have storage hypervisors. Wikipedia states that a hypervisor is “conceptually one level higher than a supervisory program”. We also know that from our normal use of hypervisors that they manage the underlying resources that a guest uses. Do these definitions work for a storage hypervisor?
Toronto based start-up Gridcentric, is developing a technology that it refers to as Virtual Memory Streaming that has the potential to reshape the economics of VDI, and deliver the holy Grail of a VDI desktop for less than the price of a PC. It should come as no surprise to hear that the single biggest performance challenge that all large VDI environments face is the boot storm. The Windows boot and logon processes generate many times more IOPS traffic than steady-state user operations. So much so that in poorly specified systems a boot storm will overload the storage infrastructure, starving Windows of resources and leading to excessively long start-up times.
The virtual storage market is hotting up with Virsto Stoftware’s announcement of two new products for release Tuesday, January 17th.
Following on from its June 2011 acquisition of EvoStor and building on its existing Virsto for VDI platform, Silicon Valley-based Virsto Software has made good on its investment by announcing the release of Virsto for vSphere.
