vSphere 6: NFS 4.1 Finally Has a Use?

February 3, 2015 By Stephen 2 Comments

Way back in the 1990's, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and ... crickets.

The Rack Endgame: A New Storage Architecture For the Data Center

September 3, 2014 By Stephen 3 Comments

Although today’s enterprise storage arrays target "the fat middle" of the market, virtualized and distributed storage change everything. What form does enterprise storage take in the new data center? Think top-of-rack flash, bottom-of-rack capacity, and a whole world of new interconnects! Here's the Rack Endgame series: The Fat Middle: Today’s Enterprise Storage … [Read more...] about The Rack Endgame: A New Storage Architecture For the Data Center
