HP VMA SAN Gateway Installation and User Guide
To separate cluster network traffic from cluster management traffic, you can
configure virtual LAN (VLAN). Network switches must also be configured to
provide a private VLAN if it will be used for the cluster network traffic.
For best performance and minimal impact on the customer network, HP
recommends configuring a private network for use by the cluster through VLAN
tagging.
Each network switch port connected to a HP VMA SAN Gateway should be
configured to allow VLAN-tagged traffic for the given cluster VLAN ID. By
default, the cluster VLAN is assigned to VLAN ID 10. This is a configurable
option that you can change to suit your network setup. For more information, see
Some switch vendors, including Cisco, do not allow untagged traffic over an LACP
link. If you are using this type of switch, you must provide the HP VMA SAN
Gateway with the public-facing VLAN (in addition to the cluster VLAN) and tag
the ports appropriately.
Note:
The system uses mDNS for cluster communication. This needs to be allowed
on all switches and uses group 224.0.0.251.
HP VMA SAN Gateway Cluster Configuration
After the system hardware is set up and cabled correctly and the VMA Array is
configured, you may configure the HP VMA SAN Gateway cluster.
Phase 4, HP VMA SAN Gateway Cluster Configuration, includes the following
procedures:
•
Configuring the Master HP VMA SAN Gateway: The first step is to
configure the master node of the HP VMA SAN Gateway cluster and define
the global cluster parameters, which are inherited by each node subsequently
added to cluster.
•
Configuring additional HP VMA SAN Gateways: Connect to each
remaining HP VMA SAN Gateway node to set its hostname and local system
parameters.
Once the initial configuration is set up, you can use the VMA Web Interface to
finish configuring the application, as described in
