Is there a good solution to provide failover between two identical servers based on Solaris 11 Express? We replicate data between the two SANs now, but want to setup a failover solution.

I have looked at IPMP as a alternative, but is not sure if it is a good solution when it is between two hosts? As the SAN2 is identical to SAN1 and communicates through iSCSI, a IP address change should be a working solution? It's most likely that the clients lose any active sessions, but it would be a minimal impact and downtime(?)

What is your architecture? Also, what are you trying to fail over? Do you have a database running on the servers? Or a custom app? NFS? Web server? – MikeyB Aug 5 '11 at 16:10
Virtual machines, Xen. I added more information to my first thread. – Jerry Aug 5 '11 at 20:53
Please get your terminology straight - it's not clear what you want and what you have. – pfo Sep 7 '11 at 21:45
Can we assume that Solaris 11 Express is your fileserver? – CyberOptic Sep 13 '11 at 14:35
Is Nexenta high-availability an option? – ewwhite Sep 13 '11 at 21:43

If you are looking for HA solutions based on Solaris then you probably don't want to go Solaris 11 Express. Even Oracle Solaris Cluster doesn't support Solaris 11 Express.

Stick with 10 unless there is a compelling, overriding need to go with 11.

Thanks for your answer Rowley. There are features of ZFS we need to use, such as encryption, which is not supported in earlier versions unfortunately. – Jerry Aug 5 '11 at 15:50
