Best Practices

This sections provides some “best practices” recommendations for DMS usage, 
including:

“High Availability and Redundant Configurations” on page 7-3

“Choosing the Right DMS Options” on page 7-4

“General Precautions” on page 7-4

High Availability and Redundant Configurations

The following recommendations pertain to high availability (HA) and redundant 
configurations:

The iSR6200 is capable of detecting and performing load balancing over 
multiple paths. To achieve the highest data migration rates, zone multiple 
ports from each array controller with each port of the iSR6200.

To maximize performance, zone each iSR6200 Fibre Channel port with one 
or two ports from one of the array controllers. 

To optimize performance, QLogic recommends that LUNs under migration 
are balanced across two controllers of a storage array.
