I am going to get a storage server which will be connected to my
Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage
server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will
have a 50% share of the RAID10 array, space wise).
What is the best way to go about this? Should I:
a) Split the RAID10 array into 2 partition on the storage server,
and export 1 partition to each xen host, then let the Xen host manage LVM?
b) Do all LVM stuff on the storage server and export each LVM
logical volume to the correct Xen hosts via iSCSI? Since each host could have
around 100 VMs on it, that's a lot of iSCSI exporting!
Any help is appreciated
