Analysis of characteristics of modern data center with high redundancy level

Moderni podatkovni centri certificirani prema Uptime institutu dijele se u 4 različite kategorije prema topologiji i elementima od kojih se sastoje. Kako bi najviša razina (4) bila ostvarena, moraju imati visoku razinu redundancije kritične infrastrukture koja omogućuje neprekidan rad bez obzira na eventualne kvarove ili nestanke napajanja. Osim ostvarivanja visoke razine dostupnosti, u modernim podatkovnim centrima jako je važna optimizacija potrošnje električne energije. Pokazatelj efikasnosti infrastrukture podatkovnog centra je koeficijent PUE. Važna karakteristika modernih podatkovnih centara je modularnost koja omogućuje vrlo jednostavnu nadogradnju i proširenje kapaciteta centra uslijed brzog napretka tehnologije i rastom zahtjeva tržišta. Na temelju opisanih karakteristika, u razmatranom podatkovnom centru su analizirani kritični sustavi infrastrukture. To su klimatizacijski sustav u obliku tople zone, sustav besprekidnog napajanja s baterijskom autonomijom i pričuvnim generatorom, dvostruka distribucija električne energije unutar svakog serverskog ormara s A i B strane, sustav za detekciju i suzbijanje požara te praćenje i upravljanje infrastrukture pomoću računala.Modern data centers that are certified by the Uptime institute are divided in 4 separate tiers based on their topology and elements. For the highest (4th) tier to be reached, highest redundancy of critical infrastructure is required. High re the dundancy of critical infrastructure allows uninterrupted running of the data center even if faults or maintenance events occur. Other than attempting to reach the highest levels of availability, in modern data centers it is of utmost importance to achieve energy consumption . optimi z ation of electrical The best indicator of data center efficiency is the PUE factor. Important characteristic of all modern data centers is modularity which allows for simple upgrades and expansions when the fast growing market an technology renders its capacity too small. Critical infrastructure systems are analyzed in the d rapid advancement of considered data center described characteristics. These are the air conditioning system in hot a based on the isle containment, u ninterruptible power supply with battery autonomy and a backup generator, supply within racks from A and B side , dual power fire detection and suppression system, c enter infrastructure management (DCIM)
