The building could structurally house ten of the generators, seven metres in length and three metres in height, although at present only six are being installed — four on line and two as backup.
The number of generators will provide 99.9999 per cent availability to the data centre.
Ten generators would use around 200,000 litres of fuel a year, according to Andrea.

Yeah, I wondered about that... the only thing I could think of was in case of fire -- it'd be easier to isolate the fire on the top floor instead of the lower floors.
But it seems like a lot of effort to build the fifth floor (and the floors below it) strong enough to hold 220 tonnes worth of generators...
Well hot air rises, you don't want to add to computer heat, so put it near the top so its easy to get rid of.
Solar only works for the 'day', not very effective for power backup, and solar couldn't generate anywhere near the amount of power these guys would need.
why not solar? must be pretty sunny in QLD most of the year round. 6 x 22 tonne diesel generators are going to be doing some heavy greenhouse gas damage.
715g of carbon per litre
x 200,000 litres
= 143 tonnes of greenhouse gas per year.
that's equivalent to around 18,000 homes.
happy to be corrected on the maths
The generators only run on a power outage and that is likely to be 0.005 of the operational time. A gernerator for News Corp in Adelaide was pulled out after 25 years with less than 60 operational hours.
All legit questions and comments in this blog. These guys dont even know how a rotary UPS works, leave alone a data centre! And as for this guy being a data centre design specialist and the company writing the ICT Masterplan for Springfield, what a load of BS! This is the first data centre they have ever done. Additionally, this will be a classic energy-inefficient data centre with a poor PUE in excess of 1.7.....millions more kgs of CO2 to the atmosphere. Very responsible design!

Yes, the 200,000 litres/year of potential fuel use was presumably a furphy from the reporter, not the designer... Unless they are planning on SE-Qld going truly Third World. Better to mention if they were trying to 'sync' the 50Hz of the various generators (the bane of power generation). Presumably each generator drives only its own circuits, and if one generator does not start do they live 'flick across' (load transfer) to another (spike arrestors needed etc).
But with any reasonable amount of fuel stored on upper stories of a glass building, biggest worry might be this generating of publicity around what is stored where. The original Comm Bank data centre was built in Sydney CBD on the corner of Liverpool and Castlereagh Sts in the 1970s. (newer Burwood data centre is late-1990s). The CBD design pre-dated 9/11 by 25years but nevertheless had concrete walls on all data centre floors, with the design spec being to tolerate a bazooka attack (the then most-powerful likely attack from outside). It seems that the glass curtain walls are a step-backward. Still, it must make any other tenants/staff in the building 'relaxed and comfortable' to know that there is a lot of diesel fuel above their heads. And of course the main risk is 'internal', where most unstable disgruntled employees can only waive magnets near tapes etc... They'll need good psych vetting, as you wouldn't want anyone in that building 'going postal' (ref to prior disgruntled employees causing mayhem).
Syncing multiple generators is not that hard with modern controls - it's done routinely right across the country.
I also doubt the bulk diesel store is on the 5th floor - most likely nothing more than day tanks (which even the CBA facility on Liverpool St had on it's upper floors).
The glass you are seeing in these photo's is from the office tower next door. The data centre itself has minimal glass - the foyer so that the security personnel can see out, the boardroom and a limited amount of tenant office space. Behind the glass the technical floors are protected by thick concrete walls.
Level 5 has day tanks for diesel only - wouldn't make sense to have the main storage facility on the roof. Similarly teh 1.5 megalitres of water stored for cooling is NOT on teh roof!

Why put the generators on the 5th floor rather then the ground floor?
