Kata siapa tidak bisa bangun Data Center di rumah? Saya sudah buktikan, di perumahan Tamansari CyberPark Bogor, kami bisa membangun data center mini, bahkan di ruang kamar tidur utama. Kamar tidur utama disulap menjadi area raised floor sehingga semua perkabelan bisa tertata baik dibawah. Dengan akses fiber optic kecepatan tinggi dari salah satu pusat bandwidth nasional, kami tidak kuatir masalah kecepatan akses Internet. Suasana sejuk kami rasakan sepanjang hari, tetapi kami siapkan 2 unit AC 2 PK untuk menjaga kondisi ruangan. Me…
Is Hot Aisle Cold Aisle Dead? For years we have been zeroing in on the ultimate in cooling efficiency: Cool air ducted directly into equipment and hot air ducted directly out. The ducts carry the respective airstreams to and from HVAC equipment without mixing or leaking into the ambient room space. It has been a long journey from the early days of datacom cooling where we simply flooded the room with an abundance of cool air. Of course the assumption was that the cold air would migrate to where it was needed and the hot exhaust air would …
Power Usage Effectiveness - PUE The boss called, "What's our PUE?" Do you know your PUE? PUE stands for Power Usage Effectiveness and it is rapidly becoming the number to know. In the past, data center managers were simply asked to provide enough space, power and cooling to support the IT equipment. Now, the same managers are being asked to do it efficiently. PUE can be a helpful benchmark. Introduced by the Green Grid, PUE is a measure of efficiency. It is defined as: the total facility power consumed divided by the to…
The Secret to Watts, BTUs and Tons Tons of electrical energy, Watts of cooling? When it comes to data center design, operation and optimization, it is all about power and cooling. Of course, the power supplied and the heat removed are closely related: in their simplest form, both are just measures of energy. Yet, it is often difficult to directly compare the two. The challenge: power and cooling each have their own language. For electrical systems, we use terms like volts, amps, KVA and watts. When discussing cooling we usually talk in …
