Network configurations
Host systems can connect to an XIV system over a Fibre Channel network or over
an Ethernet network by using the Internet Small Computer System Interface
(iSCSI) protocol.
Restriction: Direct attachment between hosts and the XIV system is not supported.
Host systems must not have a mix of Fibre Channel and iSCSI connections to the
XIV system. If your situation requires you to temporarily mix Fibre Channel and
iSCSI host access to migrate data, you must plan carefully to avoid data loss.
Important:
v Host traffic can be directed to any of the interface modules. The storage
v Always employ multipathing for data connections. If multipathing is not used, a

Fibre Channel network configurations
Host systems can connect to an XIV system over a Fibre Channel network. In a
production environment, always connect Fibre Channel hosts to a minimum of two
separate SAN switches in independent fabrics to provide redundancy.
Several network configurations that use Fibre Channel are technically possible, and
each configuration varies in terms of cost, flexibility, performance, and reliability.

administrator must ensure that host connections avoid single points of failure.
The server administrator must ensure that the host workload is adequately
balanced across the connections and interface modules. This balancing can be
done by installing the relevant host-attachment kit. Review the balancing
periodically and when traffic patterns change.

connection and an interface module fails, a host-connection error is also
displayed.
Not all host systems support multipath configuration between the protocols.
