VOD delivery services are cached in RAM on Live-Only servers

[limited]

For "Live only" server profiles (profiles w/o a Drive_Letter_Prefix), VOD Delivery Services can be assigned. These delivery services are silently (without warning the user) cached in RAM, rather than disk as would be expected.

I would expect Traffic Ops validation to warn users or block this configuration when:
a) A VOD DS is assigned to a server profile without a disk storage volume
or
b) The parameters defining a disk storage volume are deleted from a profile.

this use case can be satisfied using the newly released server capabilities functionality @PeterRyder that introduced in TC 4.0. Closing. Please reopen if you disagree.
