Equallogic 6510 Replication Setup.

Hi Team,

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 20.20.20.21and eth0/1 are 20.20.20.22 and 23

DR Equallogic is

Dedicated mgmt is 10.10.10.40 and eth2 is 10.10.10.41.

Group IP is 20.20.20.100 and eth0 is 20.20.20.101 and eth1 is 20.20.20.102.

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 .
