There are so many configurations of racks, it's not even funny. Where do you guys keep your storage located?
I think the problem I'm having is that they're currently set too high in the rack and cold air isn't getting to them. The cold air is short cycling from all of the servers with lower rack placement.
Should I give the storage its own rack on the other side of the room, put storage on the floor and blades/servers up high? I've got about 70~80U of storage in a small room with about 14 racks (approx 4 racks wide and 4 deep with alternating hot/cold aisles). Thanks for any ideas.
With all respect, that makes logically zero sense.
You say further down:
If you have proper hot / cold aisles (that are closed on top) then there is no way that hot air gets back into the cold aisle. No way like physically impossible.
If you do NOT have a proper cold aisle that is isolated - get one. Because with lots of racks and storage your run an energy density that you can hardly get cooled otherwise. Pump enough fresh / cold air into the cold aisle and you will get cooling.
Do not physically make air exchange impossible and you are wasting huge amounts of efficiency at the air flows you need there.
