Last Monday I posted a video of the new [\~joels:/2008/08/04/XenServer "Orlando" Disaster Recovery] in our upcoming XenServer release.
Today it’s time to show another new functionality in XenServer “Orlando”: High Availability.

Great job with the video.
I just got XS 4.2 installed and even the server console looks impressive.
Will NFS storage support for the HA be available in a future version?We are not using ISCSI or FC storage and would like to be able to use the HA feature.
You can have NFS storage for your VMs, you just need an iSCSI of FC LUN for the heartbeat disk. We are planning to also inlcude NFS as a vaild location for the heartbeat disk in a future release.
From the Admin guide:
Shared storage, including at least one iSCSI or Fibre Channel LUN of size 356MiB or greater -- the ‘heartbeat SR’.
The HA mechanism creates two volumes on the heartbeat SR:
4MiB heartbeat volume Used for heartbeating.
256MiB metadata volume Stores pool master metadata to be used in the case of master failover.
_If you are using a NetApp or Equallogic SR, then you should manually provision an iSCSI LUN on the array to use for the heartbeat SR._Joel
