Just noticed a behaviour that we were not expecting.
We have a vDisk, configured for 'Cache in device RAM with Overflow to HDD'. This vDisk, for versions that are in Production mode works. The WC disk is configured and the cache is used as expected. In the Virtual Disk application it also shows the cache mode being used correctly.
Our assumption (given we can't find any documentation), is that a vDisk in Test mode would behave exactly like Production.
However, a vDisk in Test mode uses 'Cache on Server' - which means that you don't get to 'test' your configuration without booting the vDisk into Production mode.
Has anyone else noticed this, or does anyone else know if this is meant to be the behaviour?
