Blue Gears - Combining Networks on VMware Virtual Switches

An often discussed VMware ESX issue is how to combine the various networks within the virtual infrastructure or even if they should be combined on the same vSwitch. Combining networks should only be done if you are low on network...

Blue Gears - VMware HA and Losing a Switch

Power outage lead to VMware HA toggling on and off repetitively and prevented proper booting of DNS, and other crucial VMs. Redundancy is required to survive such events. My office, is not as redundant as I would want. Mainly...

Blue Gears - NAS/iSCSI Storage within the virtual network

A common question on the VMware Communities Forums is what is the best way to attach NAS or iSCSI storage to the virtual infrastructure. In the blog Blue Gears - Virtual Networking I mentioned that there are several networks and that...
