If more than one data path to the virtual disk has the same weight value, the round robin with subset path selection policy is used to route I/O requests between the paths with the same weight value. The least path weight load balance policy is not supported on Linux operating systems.

Changing Load Balance Policies On The Windows Server Operating System

Load balancing with the PowerVault MD series storage array can be done from the default round robin with subset by using either the:

•Device manager

•Disk management

Changing Load Balance Policies Using Windows Server Device Manager

Follow the steps to change the load balance policy using Windows Server device manager:

1.Right-click My Computer and select Manage to open the Computer Management dialog box.

2.Click Device Manager to show the list of devices attached to the host.

3.Right-click the multipath disk device for which you want to set the load balance policies, then select Properties.

4.From the MPIO tab, select the load balance policy that you want to set for this disk device.

Changing Load Balance Policies Using Windows Server Disk Management

Follow the steps to change the load balance policy using disk management:

1.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.

Setting Load Balance Policies in Linux

Linux only supports round robin based load balancing. For more information, see Round Robin With Subset.

Setting Load Balance Policies in VMware

VMware supports Asymmetric Logical Unit Access (ALUA). For more information on Most Recently Used (MRU) and Round Robin (RR) load balancing policies, see VMware documents.
