Interface Pairs
HPE uses the term interface to identify specific ports on the controller. For iSCSI, an interface is an Ethernet port connection
that can be used for data, management, or both; for Fibre Channel, an interface is a Fibre Channel port connection that can
be used for data only.
The purpose of interface pairs is to ensure high availability and redundancy in the event of a controller or network switch
failure. In the event of a controller failover, proper network connections ensure minimal data service interruption.
To minimize single points of failure, connect as many interface port pairs as possible.
iSCSI Interface Pairs
An iSCSI interface pair refers to a set of two data or management Ethernet connections, one from each controller, to the
network switch. The cables for an interface pair connect to the same data or management port on each controller. See Interface
Numbering on page 19.
