Although the SMAPI book does talk about VMRM, The Performance book Chapter 17 "VMRM SVM Tuning Parameters"
contains the real guts of it,

I think I would approach solving this problem by using the Virtual
Machine resource Manager function. VMRM is a set of virtual machines (an
administrator and a svm) that dynamically vary the share and i/o rate
settings of other virtual machines in order to meet predefine workload
goals and performance objectives.
Tim could define a named workload, consisting of only those user ids
that need to have their performance objectives changed dynamically. He
then can grant write permission to the SFS directory where the workload
configuration file(s) are stored to only those users permitted to change
performance objectives. They, then in turn, can update the workload
performance file when the need arises and the VMRM svm server will
automatically pick up the changes and adjust it's performance goals
accordingly.
No muss, no fuss....;-)

Have a good one.
