After months of beta testing boasting 12,000+ beta testers, VMware has finally thrown its hat into the hyperconverged virtualization space with the GA release of VMware vSphere 5.5 Update 1. Among numerous bug fixes to vSphere, this release contains the GA code for VMware VSAN. VSAN is a shared-nothing clustered storage technology embedded in the vSphere hypervisor, ESXi, that uses collections of local, direct-attached host storage to provide reliable and high-performing storage to a vSphere cluster. It relies on both traditional rotating disk media and modern flash and solid-state drive (SSD) storage, forming clusters of up to 32 ESXi hosts over 1 Gbps or, preferably, 10 Gbps network connections.
We are constantly reminded that the PC market is contracting, crashing, fading out of existence. There are many possible reasons behind the hard statistics, ranging from global recession to the aberrational removal of the Start Menu in Windows 8. Some, however, argue that the prevalence of desktop virtualization projects is also a factor in this continuing decline. Could this actually be true?
So, the key value associated with Unidesk is its layering technology. The reason for this is that it enables customers to have VDI deployments and not be consumed with worry to the same degree as are most shops that have persistent VDI instances (VDI VMs assigned to one user that are always available and always for that user specifically). It allows for non-persistent VDI VMs—the Holy Grail, for lack of a better term—for all VDI deployment scenarios. One golden image, which is deployed to users on demand.
Recently I spoke with Mike Chase of dinCloud regarding its desktop virtualization offering. I hadn’t actually come across dinCloud before, as it is a fairly youthful company. However, its VDI offering—which it refers to as HVD (hosted virtual desktop), making an important distinction, because the solution can be on-premises, off-premises, or hybrid—is effectively a separate, purpose-built VDI infrastructure that can be deployed as public or private cloud.
Recently, I wrote an article about what Citrix has done around virtualizing GPUs and GPU sharing, based on a podcast with Derek Thorslund, director of product management for HDX at Citrix. When the story hit the social media sphere, I got clobbered with hits about Nutanix and its partnership with Citrix and NVIDIA, along with a handful of requests to lead a podcast and write about its involvement with the GRID vGPU tech in its virtual desktop infrastructure (VDI) business. So, just for the folks who reached out, here is my response. Continue reading VDI, a Beauty & a Beast: A Nutanix Story
One of the most common complaints that arises from users in the aftermath of a desktop virtualization deployment (whether it is done via pure virtual desktop interface [VDI] or some form of server based computing [SBC] solution) is that performance doesn’t measure up to their expectations. A negative image of the new platform develops and often spreads throughout an organization. Why is this? Are we failing to manage our users’ expectations properly, or is the perceived poor performance symptomatic of inadequate planning and bad implementation?
