Appendix—Load Balancing 85
Two sessions with one TCP connection are configured from the host to each
controller (one session per port), for a total of two sessions. The multi-path
failover driver balances I/O access across the sessions to the ports on the same
controller. In a duplex configuration, with virtual disks on each controller,
creating sessions using each of the iSCSI data ports of both controllers
increases bandwidth and provides load balancing.
