PurposeIP Address

For iSCSI arrays, each subnet has its own discovery IP address. It enables the iSCSI initiator to discover

iSCSI targets for the volumes on the array. You can use this IP address for data as well as management

in a single shared network.

Note: Discovery IP addresses are not required for Fibre Channel arrays.

Discovery

One or more IP addresses can be configured to carry data traffic. One data IP address can be configured

for each interface pair (corresponding interfaces on the two controllers). Both controllers use the same

IP address but never at the same time because only one controller is active at a time. Other data IP

addresses can be configured on different subnets.

Note: In a dedicated network topology, the data IP addresses cannot be the same as the

management/iSCSI discovery IP addresses.

Data

Each controller on an array must have a dedicated support IP address, which can be used for trou-

bleshooting and technical support purposes in the event that a controller is not reachable through the

management IP address. The support IP addresses must be placed on the group management subnet.

Firewall Rules

If your organization restricts outbound internet traffic you might need to configure rules which allow the Storage SAN

(Management IP address and Controller A and B diagnostic IP addresses) to communicate with storage servers on specific

ports.

The storage SAN requires the following firewall rules:
