Identifying the network connections
This section identifies the hardware and software ports on the nodes and describes how to
manage access to these ports. It describes the following topics:
■
Hardware ports
■
Software ports
■
Managing remote access to ports
Hardware ports
Each appliance node has three network interface ports, which operate as follows ( Figure 6 ):
■
LAN Interface—This interface establishes the network connection between the
customer’s local LAN and each appliance node; it is also called the Management Link.
Use the LAN Interface to connect to the management software through the customer’s
web browser. The LAN Interface should be on a public network.
■
InterLink—This interface establishes the Gigabit Ethernet connection between the peer
nodes; it is also called the heartbeat link. The peer nodes communicate through this link
and are connected by a crossover cable. The InterLink must be on a private network.
■
MirrorLink—This interface establishes the Gigabit Ethernet connection between the
local and remote appliance nodes. The MirrorLink is used for IP mirroring only and must
be on a private network. (Refer to “
Managing IP Mirrors ” in the HP OpenView Continuous
Access Storage Appliance System Administrator’s Guide for more information.)
Note: The LAN Interface, InterLink, and MirrorLink must not use the same network.
Because each port has a specific purpose, the TCP/IP protocol requires that each port have a
unique network number. The network number is derived from the class and subnet of the IP
address. For more information about classes and subnets, refer to your TCP/IP documentation.
You specify network information for each port using the CASA setup utility window. See
“
Setting network properties ” on page 42 for more information.
For information about using static routes, refer to “ Managing IP Mirrors ” in the HP OpenView
Continuous Access Storage Appliance System Administrator’s Guide.
Note: If the customer wants to use domain name service (DNS), be sure to specify a unique name
for each network connection.
