    28 is a little high. 22 is about right for a Datacenter

    Different opinions for data center temperature

    It really depends on air-flow, which seems to be the more important factor here.

    There's some really good articles that you can read online about data center temperature - just type in 'temperature for datacenter' in a serch engine, and there are many articles discussing datacenters running equipment fine at temperatures between 80-85F (>28C).

    also whether you are talking about ambient temperature in an open-flow air conditioned room (where the same air circulation is present at intake + exhausts) - or a hot-aisle/cold-aisle setup, where the ambient is somewhere in between the cold aisle & hot aisle or about 75% of the way towards the hot (if cold is shielded).

    In setup one - a 28 ambient means the air going in to your cabinet is about 25 or 26, and the exhaust is possibly 35. in a hot/cold aisle setup, the intakes would likely be 20, with the exhausts about 32. In bot h scenarios you would probably want to keep your power density pretty low - talking < 2.5kVA per cabinet to be safe (dependant on your server tolerances of course) - really depends on the design of the colo

    You don't really want higher than 24'c
    Sounds high to me, although equipment will probably run fine.

    Depends on the layout of the data centre - If it's 28 degrees in a hot aisle with separation between it and the cold aisle then it should be fine (Do you know the temperature across the front of the rack or the server in-let temperatures?)

    Also it might be worth bearing in mind that under the Ashrae guidelines for data centres that 28 degree is just outside of the recommended limits by 1 degree but still well within the allowable ranges (There are a few facilities, mainly in the States as far as I know, that are trailing no air-con and using ambient air to pull through servers).
