1). Actually I think I will not shutdown all servers, I choose to ventilation by fans and open the door instead. As many reasons below.
- This shutdown will take time around 9 hrs. So, some users cannot check email if have emergency case, especially Captains and BL Team.
- It's very risk and very important, if some equipment cannot boot when turn on. As it ever happened past ago. e.g. Adapter of CAT router cannot use when turn on, MM1 of Blade Server has failure since power of this building has shutdown on last time, etc. For the MM card of Blade Server, now we have the last one only. If it's fail again, maybe major impact to all systems in our company cannot use. Because we don't have a spare part and previously I ever asked IBM, IBM said their don't have this card for sale direct to customer. We need to order from other vendors instead and maybe use the delivery time about 1 month after confirmed. Also, they not guarantee will have this spare part or not. Because Blade Server nearly EOL already.
2). We able check the temperature on UPS server thru web browser.
Everage temperature on day = 25C
Everage temperature on night = 19C
And maximum temperature recorded on 28/06/2012 = 39.8C (Maybe this period as I have refer above).
3). If need to shutdown all servers, I will come also.
4). We have setup the temperature in the server room equal 22C if have aircon. For the don't have aircon, we ever had a period our aircon it does not cool, I cannot remember the temperature on that period. But all servers and network equipments still working until now. If I remember it not wrong, about 3-4 months.
5). I will borrow fans from HR & F&A department total 3 units.
