MPxIO "Logical-block" load-balancing method versus "round-robin" load-balancing method illustrated
Last updated on FEBRUARY 06, 2018
Applies to:Solaris SPARC Operating System - Version 10 8/11 U10 and later
Information in this document applies to any platform.
The Logical-block load-balancing method is fully explained in the document "Logical block MPxIO load balancing method" (Doc ID 1004918.1)
This document is intended to provide a simple test case to show up how I/Os will go through the paths if you select the logical-block method instead of the default "round-robin" load-balancing method.
It will demonstrate that logical-block is as simple as :
If we have two paths to a device then any access to the first "2^region-size/2048" MB will go down the first path, any access to the second "2^region-size/2048" MB will go down the second path, any access to the third "2^region-size/2048" MB will go down the third path, and so on.
