Hi, I''m looking for some information how to setup a redundant XEN environment, with active-active or active-passive XEN Dom0''s. I''m not sure if the drbd setup fits me as this system is going to be in production (please prove me wrong!). What alternatives do I have for a redundant setup? Anyone running a redundant setup and want to share their experiences and thoughts? Thanks! // Sten _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I''m using a San to share disks over iscsi. Redhat''s cluster suite wouldn''t work for me so I went with oracle''s ocfs2. I then used heartbeat2 to with an active-active configuration. It works great. With bonded interfaces it''s particularly stable.

Anyone running a redundant setup and want to share > their experiences and thoughts?I have two Xen-Hosts running about 30 virtual machines with a NFS Storage as Backend. The NFS storage are two servers running in active-standby mode using heartbeat and drbd as storage, which is exported via nfs from the active fileserver node to the two xen hosts. Hardware are 4 Intel Blade Server SBX82 (compatible with IBM HS20). Works fine since about 3/4 year.

This sounds like a setup that would fit very well. .Geetings Sten _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
