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. 2 Click Disk Management to show the list of virtual disks attached to the host. 3 Right-click on the virtual disk for which you want to set the load balance policy, then click Properties. 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 MD3200i Series storage array in a duplex configuration supports two active/active asymmetric redundant controllers. Each controller has four 1 Gbps Ethernet ports that support iSCSI. The bandwidth of the four 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 MD3200i 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. Appendix-Load Balancing 77

Increasing Bandwidth With Multiple iSCSI Sessions
The PowerVault MD3200i Series storage array in a duplex configuration
supports two active/active asymmetric redundant controllers. Each controller
has four 1 Gbps Ethernet ports that support iSCSI. The bandwidth of the
four 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 MD3200i
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.
