It is finally released… PXE Manager for vCenter. My former Cloud colleague Max Daneri of VMTS fame has worked very  very hard on this and actually demoed it at VMworld in 2009. I know Max is already working on the next release which of course will work with the upcoming vSphere version as well. So if you’ve tested it and [...]

Yesterday I was answering some question in the VMTN Forums when I noticed that someone referred to my article about Hybrid vs full Distributed vSwitch Architectures. This article is almost two years old and definitely in desperate need of a revision.

For those who don’t know what these options do in a VI3 environment; they allow you to access a volume which is marked as “unresolved” due to the [...]

We had a discussion internally about ESX/ESXi caching I/Os. In particular this discussion was around caching of writes  as a customer was concerned about consistency of their data.
