In 1980 I was working for Datapoint, a vendor with proprietary client hardware, proprietary server hardware, a proprietary LAN, and proprietary systems software. In 1983 IBM introduced the PC, and in 1985 it introduced the PC-XT with a hard disk. 3Com introduced Ethernet, and Novell created a network operating system. All of a sudden, Datapoint was on the wrong side of history in the computer business. In five short years, Datapoint went from six thousand employees to sixty.

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.
Today finally marks the announcement of the general availability of VMware VSAN. This is VMware’s most public beta to date. Continue reading News: VSAN Is Now GA
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
What do you do with a problem like Nexenta?
Nexenta. Some of you will remember this company from two years ago. It was the darling of Silicon Valley, the fastest growing storage start-up since NetApp. It could boast double and triple-digit year-on-year growth. And so on. So, what happened?
Back in mid-2011, Dell acquired RNA Networks, a small startup out of Portland, Oregon. At the time Dell purchased it, RNA had a product, MVX, that employed three different ways to pool memory across multiple servers in order to accelerate workloads. One was a way to pool memory as a storage cache in order to speed disk accesses using system RAM. In the spring of 2013, we saw some of these features emerge again as Dell’s Fluid Cache for DAS (direct-attach storage) morphed to use the incredible speed of PCIe-based SSDs instead of RAM. Now, in late 2013 at Dell World, we finally get what many of us have been waiting for: the announcement of the expected availability of Dell Fluid Cache for SAN.
