Re: [Xen-users] guest OS High Availability with local storage

[dan@xxxxxxxxxx]

 From my experience gluster write performance (2 mirrored nodes) is very low, approx 40-45Mb/sec. read is pretty high and it was network saturation  - appr 90-95Mb/sec (i have gigi network). For HA for VMs i'd highly recommend DRDB+Pacemaker+Corosync. Solution is much more advanced, and requires much more efforts, but output will cover all time expenses. I have cluster of 2 nodes with DRBD, some VM images (block devices, using Logical Volumes on top of DRDB) are up to 512G. I don't see any performance loss. Also Pacemaker is well integrated with XEN live migration. So i think it's best solution for "cheap man".
