But then the entire box could be a single point of failure. Here enters High Availability Manager from Hitachi Data Systems (HDS). So if for what ever reason either due to regular maintenance, or disaster or disaster testing or any other reason for that matter, if we need a failover from one USPV to other, there is a solution now. Failover always could have been done on the Storage Box, but for hosts to failover, it had to be done manually. Now even this is automated.
