Are your servers cool enough?
During a SAP R/3 implementation a few years ago in our company, with a startup of more than 10 modules and an Add-On (IS-U/CCS), can you say what was our worst problem during the startup? The temperature!
A month prior to the startup, at the begining of June, we received the hardware to install the productive system. The development was very well, adjusted to dates and the startup day, august 1, seemed to be a comfortable date to start, just when the people starts his holidays in Spain.
The problem arises when we start the new productive cluster systems and the SAN array. The temperature of the datacenter was increased until july 20, when the productive system stoped itself for overtemperature.
That mistake, that was solved buying a portable air conditioning system until the datacenter was upgraded with more cooling power, was a serious problem for a project with more than 60 people involved and six month of work.
That's something it will never happen again to me. The new datacenter has cooling power enough to mantain as far as the double of our current servers, and has multiple independent systems, but that will not be enough if you are not aware of what temperature is running on the datacenter, because the cooling systems can fail or can be power off by the cleaning lady ;-)
Now I have multiple hardware termomethers with TCP/IP, SNMP and web server enableds that can be found at W&T. That system has multiple temperature sensors so you can be aware of multiple critical points of temperature. Connecting the system to an snmp agent and you can have an online temperature monitor that can alert you of temperature arises.
