VMware vSphere Generates Insane Amounts of I/O

The news has hit the Internet in various places, but I wanted to point it out here because it does help to debunk the myth that virtualization can’t handle all workload. What’s the news? EMC and VMware have jointly demonstrated that a single VMware vSphere host running just three virtual machines can drive just above 350,000 I/O operations per second (IOPS).

VC105: The Marriage of Figaro

This is Christofer Hoff’s session at Virtualization Congress. The title of the session is “The Marriage of Figaro: Complexity and Insecurity of the Cloud”. I’m looking forward to the presentation, as I’ve heard some great things about Christofer’s presentations.

(Even if I did get a wireless connection, the network here at Synergy seems to be incapable of supporting the demands placed upon it.)

Sanbolic Brings Snapshots to Melio FS

Sanbolic is continuing to differentiate its clustered file system, Melio FS, in advance of the rudimentary clustered file system Microsoft plans on introducing in Windows Server 2008 R2.

The new snapshot functionality provides support for VSS and “full industry standard APIs,” although I’m not really sure what those “full industry standard APIs” are exactly.
