Sometimes this approach works, with few exceptions everybody understands what is meant by “thin client” and “zero client” even when the details of the implementation are wildly different – a Dell Wyse Xenith 2 zero client and a Pano Logic G2M zero client may have widely diverging approaches to delivering a zero configuration plug and play experience, but their appliance-like nature and operational benefits are the same.
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?
The 6/28 Virtualization Security Podcast we spoke about attacks, defense in depth, and compliance with Davi Ottenhiemer and Matt Wallace. Davi and Matt just published a book on how to defend your virtual environment against attack. Unlike other books, this approaches the problem from the point of view of well know attacks. It even gives examples of some of the more interesting attacks against any of the virtual environments, not just VMware vSphere. The discussion eventually found its way to even newer attacks and their impact on the environment.
Storage Security is not only about Encryption, which is just one aspect of Storage Security requirements for the virtual and cloud environments. It is also about increasing defense in depth and knowledge of what is touching your storage environment. As well as providing security around those touch points and to a great extent auditing and protecting the data residing within the storage devices regardless of where the devices live: within the virtual environment or within a cloud.
Virtualization Management is sufficiently different from systems management so that it is likely that VMware and Dell will disrupt the traditional systems management business instead of simply participating in it. This will hasten the demise of the legacy systems management vendors like IBM, CA, HP, and BMC.

Perhaps with the release of 2012, Microsoft have a rare moment of being a vendor that made a change to product licensing without upsetting someone. There are now only four Windows 2012 Licensing versions, and licensing is processor and client access license based. Sometimes, it doesn’t have to be hard.
In my humble opinion, 2011 was the year for storage inside the virtualization space with a lot of new storage related technologies presented at VMworld 2011. There were different technologies ranging from Tier 1 SSD storage in a box that can plug right into VMware vSphere as its own datastore, to all the software storage venders that are now virtualizing their Storage Processers. Yes, for me, 2011 was the year for storage in virtualization.
