After a chat with my one of our business partners, I thought I would add some more info about XIV and QoS:
- You need your XIV GUI to be on version 2.4.4 and you need your XIV to be on code version 10.2.4.
If your not on those levels, you will need to upgrade before you can use this feature.
The GUI is easy, just get it from here. The XIV code needs to be upgraded by IBM.
Talk to your local IBM Rep if you need to get this done.
- You can control all aspects of QoS using xCLI.
Why is this cool?
Consider this idea:
Script the movement of hosts into and out of performance classes on a regular basis.
You could have pre-set bandwidth levels based on time of day, or day of week or end of month.
- This feature lends itself to multi-tenancy.
By setting a maximum bandwidth value on each tenant, you can ensure that each tenant gets a fair share of the grid.
