VMware showing off more on Storage IO control coming in vSphere 4.1
By Brian Suhr
With more talk about Storage IO Control (SIOC) each month, VMware is starting to leak more details about the feature. The best write up on the feature was by Scott Drummonds last month that you can read here. With SIOC you will be able to have almost a quality of service for VM’s in regards to storage IO control. With a very simple setup showcased in the video below you can level the playing field so that something happening in one virtual machine does not monopolize all of the storage bandwidth and starve other machines.
A few things to keep in mind for now. That SIOC is enabled per datastore, does not have a reservation limit at this time, only enforces limits when a threshold is reached and can enforce limits for IOPS when specified at the VM level. Thanks to Duncan for these details.
In the images on the right you can get an idea of how Storage IO Control is working along with Shares applied to Virtual Machines to stop any VM from hogging all of the IO.
