To use this feature, the following requirements must be met:
- Two PowerStore clusters connected by a replication network.
- Configure the two PowerStore Clusters as Remote Systems to enable replication.
- Linux hosts should have SCSI connectivity to one of the PowerStore clusters in a non-uniform configuration.
- Linux hosts must have SCSI connectivity to both PowerStore clusters in a uniform configuration.
- Metro Volume only supports FC and iSCSI protocols for host access.
- Although optional, Metro Witness is highly recommended for additional resiliency. It acts as a tie-breaker in split-brain situations and further mitigates risks of unwanted downtime and interruption. For more information about the witness, see the Witness section in this document.
The supported list of operating systems changes over time. For the most current information, refer to the Dell PowerStore Simple Support Matrix on Dell.com/powerstoredocs.
