Your customer wants a multi-site P4000 configuration across campuses. Site protection has to be implemented where retention of full site data is possible when there is loss of communication between si

Advanced Snapshot Replication creates asynchronous point-in-time copies and does not guarantee a continuously current, full data copy at the remote site when the link drops.

Remote Copy requires an active network path between sites to replicate writes; when inter-site communication is lost, replication halts and the remote site may hold incomplete or stale data.

HP P4000 LeftHand SAN Network RAID (particularly Network RAID-10 in a multi-site topology) distributes and synchronously mirrors full data sets across storage nodes at each campus location. Because each site holds a complete, up-to-date copy of the volume data, loss of the inter-site network link does not cause data loss and local operations continue with full data retention - exactly the site-protection requirement described.

Failover Manager manages quorum and automates failover decisions but does not itself store or replicate data - it depends on Network RAID or another replication mechanism to ensure data is actually present at each site.
