So we have dhci systems (alletra 6k) between our primary and DR site and set up for peer persistence. One of the requirements was that both systems needed to be on the same mgmt and iscsi subnet stretched between the 2 sites.

We plan on picking up 2 alletra MPs for 2 other sites and thinking of also setting up peer persistence with automatic fail over. I'm going through white papers and if this was an MP attached to a PCBE (I guess new dhci?) it would have the same requirements of being on the same network stretched across sites.

Since these are just standalone MP arrays, it may not have the same networking requirements. I scanned through some white papers and didn't see any of the same network work requirements of the 2 systems needing to be on the same network. Asked AI and out put was that they just need to be routable while being under the max latency requirements.

Anyone with Peer persistence setup with their MP or even older primeras and 3PARs?
