Data centre, data warehouses and server houses have a very strict environment where by security, temperature and hardware means are used to provide the servers with the ideal environment.

Take blade based servers for example, imagine a 20 blade servers in one rack, where 20 racks could be situated within one room. Imagine hundreds of web servers all running in unison and then data management servers backing up that data. Take around 40°C as an estimate times this by 20 then by the amount of racks and that’s quiet hot!

I’m not here to get into specifics of the hardware/ server side of the technology and how they adopt bespoke engineering to eliminate overheating, power failure and so-forth but to basically state the importance of temperature.

Air Conditioners of all scales depending on the application are used. More dedicated data centres use in build air conditioning for faster air flow and constant target temperature.

Recently I posted that Pioneer have developed an optical disc that can store 400 GB worth of data but now scientists in the US have apparently created an 1 Terabyte optical disc which store’s all the discs data in 3D. The scientists announced that they have found a way to create hundreds of layers on a single optical disk, with each layer containing around 5GB of data.

The Californian scientist even claim they could create up to 5TB optical disks by using 405nm diodes to record a Blu-ray disc’s worth of data at around 25GB per layer.

There is no sign when this new technology will be available but hopefully its not to far away as i would love my whole DVD movie collection to be on 1 disk, with room to spare.
