i have Equallogic 6510 at both Primary and DR . Priamry and DR site is just 10 meters apart. and in same Network segment but in different Vlan.
Primary 6510 is like
Dedicated Mgmt 10.10.10.20 / Member ip eth2 is 10.10.10.21
Group ip is 184.108.40.206and eth0/1 are 220.127.116.11 and 23
DR Equallogic is
Dedicated mgmt is 10.10.10.40 and eth2 is 10.10.10.41.
Group IP is 18.104.22.168 and eth0 is 22.214.171.124 and eth1 is 126.96.36.199.
How Replication configuration needs to be done in best practice now. i have Mgmt port conencted to customer network swicth from both Equallogic and Equal data port is connected to 8132F at both end and 8132F both are port channelled .
is it the best practice to have primary and DR IP address on same Range or it must be on different Subnet altogether.
how replication would be setup so replictaion traffic must be on Equallogic dedicated Group ip range/Swicthes .
The only requirements for replication is that each side must be able to reach every port on both groups. Not just the Group IP, so things like NAT firewalls can't be used. Ports for ICMP, and iSCSI (3260) must be open as well.
If you WAN, is setup as a bridge, or on a local subnet it will work fine. As long as you can solve the problem of getting the data to/from the groups, the array doesn't care how you do it.
Generally speaking DR sites are remote so bridging and IP subnet isn't as common compared to routing to a different subnet.
