At VMworld 2012, VMware announced their tech preview of vVOLS. As one thinks of cloud systems, one can see that vVOLs could be the transformation architecture that takes the disparity of traditional storage systems to a true cloud storage system for the future.
The NIST definition of Cloud Computing:
VMware's vVOLs - One doesn't have to worry about whether to use NFS or Block. No more creating LUNS in the traditional sense and setting up storage polices on the array and then the hypervisor. vVOLs also provide the redundancy and multi-tenant access to the logical volumes of objects at scale. Similar to Cloud systems by definition, vVOLs will make it easy to provision and provide multi-tenant access while removing the complexity of the different software layers.
In summation, and the point of this post, is to illustrate that vVOLs bring the storage layer and the hypervisor layer to a truly cloud state around management and provisioning. Hopefully vVOLs will make the impact on the industry in such ways that help cloud admins everywhere.
