A new high-speed memory technology from stealthy startup Nantero is one step closer to reshaping data center storage. Nantero announced on Tuesday, June 2, that it had closed a $31.5 million series E financing round, bringing funding up to a total of $78 million and opening the door to further development and future volume production of its carbon nanotube storage technology. Nantero, which has been quietly working on its carbon nanotube storage since 2001 and has been in low-volume production since 2004, is making big claims for its technology.
One of the big challenges of cloud scale data center operation is determining what to do with the waste heat. In a typical data center, cooling systems account for roughly forty percent of capital equipment costs, and thirty percent of the energy consumed in a facility goes into cooling. Data center operators are forever looking to new ways to reduce the overhead that cooling imposes. Facebook chose to site its first data center outside the US in Luleå, Sweden, a location chosen as much for its low-cost electricity, derived from 100% renewable sources, as it was for its subarctic climate, which enables the data center to use outside air cooling all year round. In Belgium, Google has taken a less direct approach. It too uses free outside air cooling for much of the year, but on days when the outside air temperature exceeds Google’s maximum threshold (Google maintains data centers at temperatures somewhat above 80°F), it avoids the issue by transferring computing load to other data centers.
On the Tuesday morning keynote that launched this year’s Citrix Synergy conference, Citrix CEO Mark Templeton took time to set to rest several years of speculation about the importance of XenApp. The message was unequivocal:
“We love XenApp.”
Amazon has taken a big step forward in its application delivery strategy, taking to the stage at the April AWS Summit in San Francisco to announce the introduction of AWS Marketplace for Desktop Apps, a dedicated storefront for Amazon’s Desktop as a Service platform, Amazon WorkSpaces, through which customers can purchase off-the-shelf applications to run on their virtual desktops. At the same time, Amazon VP Andy Jassy announced the availability of a new admin tool, WorkSpaces Application Manager, which controls admin and user access to marketplace apps.

On March 11 on the VMware end-user computing blog, Sumit Dhawan casually announced VMware’s next big thing: Project Enzo. A former Citrix exec, Sumit Dhawan is now VMware’s senior vice president and general manager, desktop products, End-User Computing.
Two weeks ago, Virtualization Practice Analyst Jo Harder mourned the passing of Citrix VDI-in-a-Box and forecasted that its target SMB market would look to hyperconverged infrastructure appliances to deliver complexity-free VDI. Dell clearly had the same thought, because just one week later, it announced the Dell Appliance for Wyse – vWorkspace (DAW vW), a self-contained hyperconverged infrastructure appliance designed specifically for small businesses and K–12 education customers (see my initial assessment: Dell Appliance for Wyse — Business-Class VDI). Capable of supporting 200 virtual desktops or 350 RDSH sessions, DAW vW is everything Jo was looking for when she asked “How will Citrix enter the hyperconverged infrastructure market and address those VDI-in-a-Box customers?” Everything except for one thing: Dell’s new appliance isn’t based on XenDesktop. It runs Dell’s universal VDI/RDSH broker, vWorkspace. But now, just seven days after it announced DAW vW, Dell has come back to answer Jo’s specific question by announcing Dell Appliance for Wyse – Citrix (DAW C), a self-contained hyperconverged infrastructure appliance designed specifically for small businesses using XenDesktop instead of vWorkspace.
