Just be aware that autofailover does have its limitations.
- the best practice for DSS software updates is to shut down the failover service (which drops all iSCSI connectivity and means you will need to take the server or servers connected to the DSS off-line), update one DSS, reboot, update the other DSS, reboot, then restart the failover services. This means your server will have downtime.
- if you want to add additional storage volumes to the failover set, you have to shut down all hosts accessing the DSS, turn off failover, add the volumes, then turn failover back on and then bring your hosts back up. Again, server downtime.
If your maintenance window permits this kind of server downtime, then go for it. Just be aware that there are times when you'll have to shut down your servers to do maintenance on the SAN.
