Set Cluster Log Size and Verbosity in Microsoft Server 2008 R2

Recently a critical cluster system had a bit of a hiccup wherein the SQL resource failed between nodes a few times and then gave up.

Supermicro IPMI Power On Server via SSH

Today I’m going to install the VMware ESXi Embedded Host Client software on one of my Supermicro SYS-5028D-TN4T lab servers.
