Today playing in my lab I had an issue running some VMs on a SSD. It turns out the Host Cache Configuration was causing some issues running the VMs on the same SSD. You enable host cache when creating a datastore on a SSD, but how do you disable it? Its not an option on the datastore properties.
To disable Host Cache Configuration follow the steps below:
- Select Configuration Tab
- Select Host Cache Configuration under software
- Right Click on the SSD Datastore and Select Properties
- Disable Checkbox for Allocate space for host cache
- Click OK
Thats it, host cache has been disabled.
