VMware Virtual Infrastructure Upgrade Underway...

We officially started our upgrade from ESX 2.5 to Vi3 on Friday. First let me give you a run-down on what we have and what our goals are. We started with 3 Dell 2850 Dual Xeon 3.6 Servers, 8GB of RAM and 2 36GB drives. They all had the two built-in NICs and we added a Dual-NIC card. For Storage, we're using an EMC CX-300 with 15x 146GB drives and two McData FC Switches. When we started, we only needed two servers, but Dell was running a special - Buy 2 get 1 free. So, we only had 2 in production. The third one did not come with the HBAs either... just the box, processors, memory & drives.

Just to make this easy, we call the first two servers that have been in production, "vm1 & vm2" The third server we'll call "vm3."

The plan was to add the HBAs and the VMware ESX license to vm3 when we found we were getting close to reaching capacity on the first two. This lasted about a year or so before we noticed that we needed to turn up vm3. Mostly because of our mail server. We're thinking now that we just need to move it back to the physical world. Anyway, we got our upgrade to VI3 the other day for our existing 2 servers and will be buying a VI3 license & HBAs for vm3 on Monday. Now we have what looks like an easy way to do the migration to VI3 from ESX 2.5.

The plan is to get vm3 up and running, move the virtual servers that are running on vm2 over to vm3. Then rebuild vm2 with VI3, move the virtual servers that are running on vm1 to the newly rebuilt vm2, then rebuild vm1. Once that is all done, we'll let DRS take over and decide where the virtual machines need to run. We'll have 21.6GHz and 24GB of RAM for it to use. Woo hoo!
