vSphere ESXi as a VM – VMKernel Traffic Not Working
Posted by on June 12, 2009
In the lab I am currently working with I have a set of vSphere 4 ESXi installations running as a virtual machine and configured in an HA cluster – this is a great setup for testing VM patches, and general ops procedures or learning about VMware HA/DRS/FT etc. (this lab is running on a [...]

Posted by on June 21, 2008
As noted here there is a doc that has been jointly produced between VMWare and Cisco which has all the details required for integrating VI virtual switches with physical switching. Especially handy if you need to work with networking teams to make sure things are configured correctly to allow failover properly between redundant switches/fabrics [...]

Hot-Swap Datacentres

This isn’t a new idea but it I’m sure the economics of scale currently mean this [...]

Posted by on February 3, 2008
