HP VMA SAN Gateway Installation and User Guide
33
A typical HP VMA SAN Gateway system will have three management interfaces.
•
1-2 & 4-5: Management Ethernet Ports (Eth1 is on right, Eth4 is on left)
•
3: iLO Management Port
In this example, 8GB Fibre SAN ports are the primary ports for failover
management. These interfaces may used as individual ports configured for
different networks or they may be bonded together to run on the same subnet for
increased throughput and reliability.
The default public interface—the Ethernet port used for cluster management—is
eth1. Cluster management and cluster data traffic must share the same physical
cabling. For cable redundancy, the eth1 and eth2 interfaces can be bonded together
as eth0, in which case eth0 is used for the cluster master interface and the cluster
interface. In a single Ethernet cable configuration, the eth1 port is used for both
cluster management and cluster data traffic. To hide cluster data traffic from the
management network, a VLAN can be used for the cluster interface. For more
Note:
For proper operation in a vSHARE High Availability (HA) configuration, the
management and cluster interfaces should be bonded to a single interface, eth0, and
that interface becomes the management and cluster interface.
Null Modem Cable Connection
Connect to the public interface by connecting a null modem cable to the
communication port of a PC.
