Roland. Freezer warehouse protection in a server room??????? Cryogenic cooling maybe?????? I see no advantage to the added complexity and just a lot of added cost in installation and maintenance, apart from the increased risk of unreliability with a DIPA. If, as you say, loss of data is the concern wet pipe with offsite backup. If continuity of business (of if a supercomputer for a server room 😵) then a SIPA with pipe integrity monitoring (12oz air) would be advisable. Or maybe if this is all so critical you can build a back-up server room with wet sprinks. Savings in not installing SIPA and its associated maintenance cost (and unreliability if not maintained properly–amazing how many "professionals" don't understand pre-action) and the cost of two hour rooms might offset the duplicate computers in another location within the facility.
And of course, on a seperate topic, there's the no storage in a room with a door clause that means there will be storage. Testing a halon with SIPA back-up once. Found four wonder gas bottles in a bank and removed the solenoid releases for the test. Fortunately the tech needed a tool and so I just wandered around a little. Found some big pressure hosing going into a closet. Looked in the closet and it was full pf empty cardboard boxes. Pulled some out and found a fifth halon bottle. lucky day.
