First off I am new to using vmturbo. I was looking through the documentation below on Risks and Actions. I was wondering a few things around IO influencing decisions or other host related functionality. First, when a move is suggested (not a storage move) is the total host IO considered? Second, in the analysis portion is the IO setting only for the storage side only? Lastly, is there a way to prioritize balancing IO, CPU Ready, CPU, as more important than balancing memory? Thank you for having a forum where these can be asked!
Whenever any system resource reaches critical utilization, your infrastructure can experience bottlenecks. Applications running on VMs that are hosted by critically over-utilized machines will show performance problems, and so your QoS may suffer.
The resources that can be affected are:
- Network utilization
- CPU Ready Queues
- Data storage
- Move VMs from the affected host to a host with less utilization. Operations Manager can perform this action automatically.
- Start or provision a new host machine. You must perform this action manually.
- Provision a new data store. You must perform this action manually.
