The ASUS Storage MPIO solution can load balance the paths for your LUNs with load balance policy set to 

Failover.

With Automatic Load Balancing enabled, the LUNs set to Failover policy are automatically redistributed among 

all available paths when:

• 

A path fails

•  A failed path comes back online

• 

A new path is added

Automatic Load Balancing, when enabled, provides optimal data throughput for LUNs set to Failover policy.

Note that Automatic Load Balancing has NO effect upon LUNs set to Round Robin, Round Robin with Subset, 

or Least Queue Depth.

Load Balance Policy is a method of equalizing the I/O traffic over each path by systematically dividing the load 

among multiple paths.

•  Failover Policy – No load balancing. With Automatic Load Balancing disabled, the first path discovered is the 

primary path. I/Os follow the active path until it fails, then they change to next available path. Each LUN 

uses only one active path.

See 

Automatic Load Balancing for Failover Policy.

•  Round Robin Policy – I/Os follow all active paths, changing paths at the specified I/O count. You can set the 

I/O count in the General tab of the Advanced Settings dialog box.

If LUN Affinity is enabled do NOT use Round Robin. See “Making Controller Settings” on page 59 or 

page 124.

•  Round Robin with Subset Policy – One or more paths are designated as standby. I/Os follow all active paths, 

changing at the specified I/O count. You can set the I/O count in the General tab of the Advanced Settings 

dialog box.

If LUN Affinity is enabled, you can use Round Robin with Subset. See “Making Controller Settings” on 

page 59 or page 124.

•  Least Queue Depth Policy

 – I/Os follow the path with the least number of requests queued.

Note that you can enable Automatic Load Balancing for LUNs with policy set to Failover. See Automatic Load 

Balancing for Failover Policy.
