Protection: Metro

Thank you for your feedback!

PowerStoreOS versions 3.0 and later support the Metro Volume implementation, which you can use for disaster avoidance, application load balancing, and migration scenarios. This feature provides active-active I/O to a Metro Volume across two PowerStore clusters. It supports FC/SCSI or iSCSI-connected VMware ESXi hosts. In PowerStoreOS version 4.0 and later, the system has expanded metro support to volume groups as well as Linux and Windows hosts. When Metro Volume is implemented, you can see the details in Protection > Metro page (Figure 31). You can use this page to monitor, end, pause, and to set the local preferred role.
