colocation providers are going to great lengths in order to minimise their cooling costs. Facilities are advised to run at temperatures anywhere between 20-30°C to achieve an optimal environment for the servers. With the installation of high performance computers however, their processing power is significantly higher, so heat management is of vital importance. Some HPC providers have tried to ensure consistent cooling by deploying liquid cooling, larger fans or conductive cooling methods. Typically however, the rate at which heat is produced is greater than the rate at which cooling accelerants or fans can dissipate this heat. It is therefore important for centres to be built with systems in place that far exceed the maximum cooling requirements, especially if there is the possibility in JULY the future that HPC systems will be installed. For those that have systems already in place and that wish to install HPCs, again significant capex spending will be needed to upgrade data halls to meet the required needs. When it comes to power HPCs run at much higher processing powers than regular servers. Measured in floating-point operations per second, or FLOPS, the fastest HPC as of last year ran at 33.86 quadrillion FLOPS. Directly tied into the first two requirements for HPCs, space and cooling, adequate processing power is essential. The necessary power infrastructure must be able to cope with these demands in order to fulfil the requirements of both the HPC and the mid-range servers, depending on the data halls configuration. Those looking to install HPCs need to factor E U S IS VIRTUALISATION & CLOUD SERVICES As well as its regular range of features and news items, the July issue of Data Centre News will contain a major feature on virtualisation and cloud services. To make sure you don’t miss the opportunity to advertise your products to this exclusive readership, call Francesca on 01634 673163 or email firstname.lastname@example.org data centre news in the provision of high density power and how this has implications for the cooling requirements and the following environmental impact. By having these necessary capabilities, customers can be reassured that the right technologies are in place to grow their estates. But in order for this to be successful colocation facilities must not do this at the expense of existing customer needs that might not require HPC. Having an entire site dedicated to HPC will noticeably restrict your customer base and therefore it is essential that any investment is still able to account for traditional mission critical applications as well as increased customer demand for dense configurations, ultimately enabling you to operate efficiency in the future.
