Increasing Bandwidth With Multiple iSCSI
Sessions
The Dell PowerVault MD3000i in the duplex configuration supports two
active/active asymmetric redundant controllers. Each controller has two
1 Gbps Ethernet ports that support iSCSI, and the bandwidth of the two
ports on the same controller can be aggregated to provide optimal
performance. A host can be configured to simultaneously use the bandwidth
of both the ports on a controller to access virtual disks owned by the
controller. The multi-path failover driver that Dell provides for the MD3000i
can be used to configure the MD3000i so that all ports will be used for
simultaneous I/O access. If the multi-path driver detects multiple paths to
the same virtual disk through the ports on the same controller, it will load
balance I/O access from the host across all the ports on the controller.
Figure 1 illustrates configuring the initiator to take advantage of the load
balancing capabilities of the multi-path failover driver.
