RE: [Xen-users] best practices in using shared storage for XEN VirtualMachines and auto-failover?

It is easier to use NFS than iSCSI for shared storage target.  If you use
iSCSI, you will need to use a cluster aware file system to avoid data
corruption.  If your storage target can do both, just use NFS.

Subject: [Xen-users] best practices in using shared storage for XEN
VirtualMachines and auto-failover?

Hi all,

Can anyone pleas tell me what would be best practice to use shared
storage with virtual machines, especially when it involved high
availability / automated failover between 2 XEN servers?

i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x
1GB NIC's, etc. Then I need the xen domU's to auto failover between
the 2 servers if either goes down (hardware failure / overload /
kernel updates / etc).

What is the best way to connect a NAS / SAN to these 2 servers for
this kind of setup to work flawlessly? The NAS can export iSCSI, NFS,
SMB, etc. I'm sure I could even use ATAOE if needed
