Appendix—Load Balancing 81
To change the load balance policy using Windows Server 2008 disk
management:
1 From the desktop of the host, right-click My Computer and click Manage
to open the Computer Management dialog box.
2 Click Disk Management to show the list of virtual disks attached to the
host.
3 Right-click the virtual disk for which you want to set the load balance
policy, then click Properties.
4 From the MPIO tab, select the load balance policy that you want to set for
this virtual disk.
Increasing Bandwidth With Multiple iSCSI Sessions
The PowerVault MD3600i series storage array in a duplex configuration
supports two active/active asymmetric redundant controllers. Each controller
has two 10G Ethernet ports that support iSCSI. 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
PowerVault MD3600i series storage array can be used to configure the storage
array so that all ports are 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 load-balances I/O access from the host across all ports on
the controller.
Figure C-1 illustrates how the initiator can be configured to take advantage of
the load balancing capabilities of the multi-path failover driver.
