Configuring a Redundant Pair of VMA SAN Gateways - Process Guide

Preparation and Establishing Primary Gateway

As part of preparation for the VMA SAN Gateway redundant pairing process, you will need to

determine which gateway pairing scenario you have and perform any actions on any previously

deployed or existing gateway configuration that are required.

Also as part of the preparation process, you will need to determine which VMA SAN Gateway will

take on the role of the ‘primary’ gateway. During this preparation process the primary gateway will

be updated to VMA SAN Gateway software OE G5.1.0 or newer and all VMA Arrays must be

upgraded to A5.1.3 array firmware or newer.

Defining the network IP addressing plan for each of the gateways in the redundant pair and also the

LAN/Ethernet switch connections are also part of the preparation step.

Define Network IP Addressing Plan

For deployment and correct functioning of a redundant pair of VMA SAN Gateways, you will need to

determine physical IP addresses for each gateway to be used for gateway management and a virtual

IP address and VLAN which will be used for communication and coordination between the paired

gateways.

Before moving to the next steps, identify the following:

• Two IP addresses, one per gateway in the pair. These will be entered in the gateway set-up

wizard as the ‘Public interface IP address’, step # 3.

• One VLAN which will be used for redirection of management traffic between paired

gateways

• One virtual IP (VIP) address which will become the public interface for user management and

seamlessly relocate to the active master of the gateway pair

If you are starting with one or two existing VMA SAN Gateway configurations as part of this pairing

process, then you may have already established the two IP addresses and possibly the VIP

address/VLAN that are required for deployment.

Ideally for redundant VMA SAN Gateway pairs, two Ethernet switches will be used for higher

network reliability of inter-gateway communication and user management of the gateways; however a

single Ethernet switch could be used to connect the Ethernet connections from both paired gateways if

desired. The rest of this pairing process will continue to refer to configuring two Ethernet switches as

part of the redundant gateway pairing process.

Please refer to the ‘Configuring the Master Memory Gateway’ section of the ‘HP VMA-series SAN

Gateway Installation and User Guide’, P/N AM456-9007B-Rev 2 for additional details and guidance

on network planning.

Determine Gateway Pairing Scenario and Establish Primary Gateway

As mentioned previously, there are three possible scenarios for establishing a redundant pair of VMA

SAN Gateways:
