Re: [Xen-users] Distributed xen or cluster?

My SAN is Active-Active, but you still should be able to accomplish this even with an Active-Passive SAN.  This shouldn't be an issue with normal operations at all - it'll just be a matter of whether things can fail over correctly in the event of a SAN controller failure.

Nick,

Is your SAN an Active-Active or Active-Passive SAN?  I'm looking to set something up like what you're doing, but my SAN only supports Active-Passive.  We originally looked at Win2K8 with Hyper-V but fortunately that requires a SAN that supports Active-Active configuration.  I'm using SLES 10 SP2 for dom0, and will be running SLES 10 SP2 domU's as well.  I am running Xen 3.2.

This way I do file-based disks for all of my domUs and they are all visible to each of my hosts.  I can migrate the domUs from host to host.  I'm in the process of getting Heartbeat setup to manage my domUs - Heartbeat can be configured to migrate VMs or restart them if one of the hosts fails.
