I had a grand plan, a lovely plan, and plan to end all plans. Well, not that good but we were going to catch up to the rest of the IT world and come up with a viable DR plan as well. The new licensing model from VMWare has seemingly killed that part way into it. Here’s a bullet list of what I was going to do:
1. Purchase HP P4300 SAN
2. Purchase 2 servers and create a VSphere 4 cluster using the Essentials Plus bundle
3. Purchase a server running embedded ESXi, lots of disk space and install HP’s VSA software to replicate data from the production SAN. This was to be our offsite DR solution.
So far I have purchased the SAN and the two host servers. I was about to order the Essentials Plus bundle when I found out about the new licensing. From what I can tell, the new licensing will force me to go to a standard license, more than doubling my licensing costs. Beyond that, an apparent 8GB of RAM cap on the free hypervisor has killed my DR site plan. I had planned to be able to bring critical VMs up on the DR site box with at worst, a weeks worth of lost data. That’s far more acceptable than having to rebuild everything from tape with no hardware on hand. That can’t happen now. A large reason for going with the HP SAN was the VSA software which I can’t use with the free hyper visor.
I have to go back to the drawing board and look at HyperV and Xen. I’ll have to see if HP’s VSA can be used in another virtual environment as well.
Microsoft and Citrix must be laughing their collective asses off at VMWare for gift wrapping new potential customers.
