Virtual Server Infrastructure
Just wanted to ask about virtual server system design when using a SAN.
I have five physical servers connected to a SAN box. The physical servers boot from their own hard disks but the virtual servers will run from the SAN.
I want to run about three virtual machines on each physical server. What is the best way to configure this?
If I take one server as an example. I want to set up a file server so it will need two volumes. A system volume and a studentdata volume.
So the options appear to be:
1) Create one volume on the SAN and attach it to the physical server. Then create two VHDs on the volume, one for the system disk and one for the data disk, and allocate them to the virtual machine.
2) Create two volumes on the SAN and put a VHD file on each volume, one for the system disk and one for the data disk and attach them to the physical server, then allocate them to the virtual machine.
3) Create two volumes on the SAN, use a VHD for the system disk, attached to the phsical server. The data volume would be attached directly to the virtual machine and not use a VHD file at all.
Anyone know which is the approved method or am I thinking completely along the wrong lines?
I'm also concerned that with the release of the new version of Hyper-V and the ability to live-migrate servers, it is important that all physical servers can have access to all volumes on the SAN, but I don't see how this is possible with any of these configurations!
Finally if anyone knows of a good guide to network design using virtual servers then that would be great.
