Is anyone using Oracle VM Server? What do you like and dislike about it, and did you use ESX in the past?
ramblings:
We have a requirement to have 5-6 Dual CPU host machines in a cluster with potential to go to 7 or 8. Currently we have 3 using the 'essentials' license.
The ESX enterprise license is as everyone knows, expensive. I found this calculator that claims to show you the difference in pricing. Based on that and the fact I couldn't find any horror stories after a quick search, I decided to consider Oracle VM Server to replace ESXi entirely. I could buy 2 built hosts for the difference in pricing, if the calculator was accurate.
After thinking about things, I wondered if I needed to stay with VMware and what I'd be giving up if I moved away.
We use NFS to connect our DataStores, In the 6 years this cluster has been in operation we have never lost a node. There is no system where the company would instantly start purging dollars if it went down for a period of time.
I'm not even sure if Oracle has VM failover to a surviving host feature (this idea is very new, like today!) , but I'm thinking we could get away with out it, here. If they do, great.
I think having a solution where I can deploy VMs and migrate them off a host, either while live or shutdown would meet our basic requirements.
My other concern is latency. Currently we have 4 internet connections from as many providers. Some are gig some are 100 meg. Because they are predominately used for bulk data transfer, and due to the requirements passed onto me (each has to be a separate firewall, no two connections to any one firewall), I was considering virtualization them to gain a level of redundancy, on a separate cluster. I could either do this using the 'orphaned ESX license', or install Oracle VM server there too. Wondering if anyone has any insight into latency through both solutions. I'll end up testing both but am curious.
I've been running firewalls in ESX for years but always just to protect hosts/networks on the cluster itself, this would be the first attempt at deploying a corporate firewall solution. Crazy idea?
be well,
