Hey Ross. I feel like there's always confusion with regards to the Exchange PA articles and wondering if you can update them. I think you should replace the word "Disk" with "Volume" where appropriate.
For example, my understanding on the JBOD is that is this:
DISK0,DISK1,DISK2,DISK3 = JBOD Volume
THEN you Bitlocker the JBOD volume, not each DISK independently.
Also, guidance on how to disable ReFS Integrity Streams at the volume level would be helpful, rather than using PowerShell to Set-FileIntegrity after the fact.
And also, guidance on how to use just a TPM as a protector on the Bitlocker volume (manage-bde I'm assuming) to "auto unlock" the encryption on boot.
