Proper cooling capacity

Anonymous user · ‎2021-06-28

I wonder if in following design insufficient, sufficient or overheaded cooling is planned:

(design assumes hot air containment - I was not precise enough - of course HACS doors, roof etc.)

one row (second one is a mirror) has:

1. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
2. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
3. ACRP 501
4. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
5. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
6. rack - wiring closet 3 kW
7. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
8. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
9. ACRP 501
10. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition
11. rack - 16,2 kW and 55.120 BTU peak, 12,3 kW and 36.480 regular working condition

Thank you for the answers.

There are so many variables to this solution but the short answer is no. You have ~200KW of server load which is more than 4 ACRP501's can cool even in a Hot aisle system. From my calculations you would need at least 6 ACRP501's and thats with a HACS included or 8 without HACS N+0 Config.
