[dm-devel] Block multipathing in an IP-SAN

[goggin, edward]

I'm wondering about how block device multipathing works in conjunction with
the high availability
features of an IP-SAN.

Does the iSCSI initiator's session layer's retransmission capability and the
IP-takeover capability
of IP-SAN switches eliminate the need for block device multipathing in an
IP-SAN?

Does the iSCSI initiator present redundant paths to the SCSI mid-layer?

Do these answers differ with software verses hardware iSCSI initiators?
