Hello.
Just starting out with Oracle VM for x86 and I'm looking for a few pointers for the best configuration for when you have 2 physical servers to deploy on. I have read some the documentation and I not sure I can achieve what I want with only 2 physical servers.
This deployment will not have massive loads placed upon it, it is planned to run various monitoirng tools, it will not be running massive databases or anything like that, but would like for it to be reasonably robust.
The 2 servers (they are identical) I have are:
2 x Oracle/Sun X3-2, each with Xeon E6-26680 8-core, 128GB RAM, 3 x 600GB SAS15k, 6GB SAS PCIE HBA, Int 8 port
My colleague started this project and he has moved onto other projects, so I'm getting to pick it up.
This is how it was imagined it would work, and probably incorrectly.
Configure both servers the same way, for all services, however, they do not share networking or power, they are independent in that respect, different UPS/switches. The 2 servers work together (heartbeat) and if one should fail the other picks up the slack. We had 2 Xen VM hosts running successfully like this, and it was assumed we would be able to do this with Oracle VM.
Something like this
Option 1
Server 1
VM Manager
Server Pool Master
Utility Master
VM Server
|
|
Server 2
Server Pool Master
Utility Master
VM Server
Having read some of the documentation, I left thinking that I cannot really achieve this. If I go for a single server pool and the “All-in-one” configuation, it would give me a single point of failure.
Option 2
All-in-one
Server 1
VM Manager
|
|
Server 2
Server Pool Master
Utility Master
VM Server
Option 3
Server 1
Server Pool Master
Utility Master
VM Server
|
|
Server 2
Server Pool Master
Utility Master
VM Server
Server 3
VM Manager
So, if I cannot do Option 1, I can't see how I can do Option 2 with only 2 servers without a single point of failure, so I would need 3.
I do have the possibility have placing the VM Manager on either another physical server (older mind mind you), or placing it on a separate VM infrastructure, VMware in fact.
Questions.
Say I go for for Option 3, a separate isolated VM Manager, if that system becomes temporarily unavailable, will the VMs hosted on the VM Server continue work? You just lose the ability to managed them for awhile.
