Using IOTAs to Determine the I/O Utilization of Your Workloads - comment by carrie

In the Workload Management Capacity on Demand orange book, there is an I/O throughput metric that can be used to assess I/O usage by workload.  See section 5.2 of this orange book.   Essentially there are several different I/O bandwidth fields in the ResUsageSPS table that you can add together.   As shown in the orange book.
 
You have to know approximately what the max bandwidth is for I/O on your nodes, then you can compare bandwidth collected by workload derived from the ResUsageSPS table against that expected max.    
 
In the orange book mentioned above the MB/second/node metrics were derived for these tests by adding together the following columns from the ResUsageSPS table:
•             FilePDbAcqReadKB
•             FilePCiAcqReadKB
•             FileSDbAcqReadKB
•             FileSCiAcqReadKB
•             FilePDbPreReadKB
•             FilePCiPreReadKB
•             FileSDbPreReadKB
•             FileSCiPreReadKB
•             FilePDbFWriteKB
•             FilePCiFWriteKB
•             FileSDbFWriteKB
•             FileSCiFWriteKB
•             FileTJtAcqReadKB
•             FileAPtAcqReadKB
•             FileTJtPreReadKB
•             FileAPtPreReadKB
•             FileTJtFWriteKB
•             FileAPtFWriteKB
 
All of those fields are available in 14.0 ResusageSPS.
