Monday, October 17th, 2016

Once I loaded the UCS image in VUM, it's a piece of cake to deploy and update the hosts. But... I had one site with 2 hosts running on IBM x3650 servers, so I downloaded the Lenovo image for this platform and loaded it up in VUM. Start the deployment, and the ...

vSphere “good practices” for Windows VMs

Saturday, May 23rd, 2015
