COLUMN talking point Physical education Michael O’Keeffe at Emerson Network Power shares his views on how innovation and optimisation have impacted the physical network over the past three decades. O ver the past 20-30 years, the physical network infrastructure has undergone some significant changes to the point that we’ve almost come a full circle. In the years before connected devices, mobile phones and the Internet of Things (IoT) had become mainstream technology, we had the era of the mainframe. Data was managed, processed and stored on one central system. Paper cards, tape, batch jobs and dumb terminals were all day-to-day necessities and in order to support this equipment, rigid guidelines about power, temperature and humidity had to be adhered to. Over a period of time, technology advanced and mini computers, what we now call servers, were introduced and we started to move towards a more distributed computing model. As technology progressed, dedicated equipment for different applications, company departments, storage and networking needs, meant more hardware in more places. Power and cooling requirements were still fairly rigid but rather than large central data centres with a central plant, we saw the advent of the computer room. Now, as cloud computing and virtualised systems become increasingly common, we are moving to a more hybri [\ۛY[]\H[[\Y]H[\YB\][ [\ݙHYY H\[\YۚYX[\]Z\[Y[܈]B[\[YHY[]Y[\Y\[YY^\H\Z[H[XH\\HY\[ \[ܙX\[[X[HۈY\][[ۛ[H\X\\ۜ[Y\[[\ٙ\[ۘ[]\]HZ[ۈH]ܚ˜[\]H[\[\YH[Y\[HوYH\][XH\HܛHو[\]]H]B[HXKYH\][›[ݙ\^H]H\[[]ܚ‚\X\]^HHH[[]B[H]H8&Yx&HوH]ܚ˂\H\X[\[K\ٝ[ۜ\›و][\HX[]ܚ[[[˜H\H[[]ܚ[]H[K\[\[[[[[YY\][^\Y[H܈Hۜ[Y\ܙX][]\ۛX]]H]Y[H\\[H]X\]HYBوH]ܚˈ]\\\\B]\[[]H[H]ܚ[˜[&\^H][H]YX\B]ܚ۸&]HZ[Y\[O‘\]X[K]H[\[\[\\B\[HۜXYY\[KY][ۘ[K]H[HZ[[\š[YH8&X [ܝ\&H\X \H]H[\]Yܙ[X[K\ٝ[\[Y[HZ^و\\BHY\[ݚY\YX[[B]\[[\]H[HX\[K]\[H[H\Z[B]H[K\]Z\[]X[[˜[ڙXX[Y[Y[ YXX]Y [[\]H[\\BZ[HܙK[X[H[ܙB^XH[۝[Y[[[[Z[[\ˈH[[\\B\YۙY[X[YX\Yٙ]B[[X\]Y[H[]\Y[\YH\[XYۈ]K\\XYX[]ݙ\[\[[YB[HYXYH\ \[ \\[ܙKYXX]Y]H[\˜\H\^[ۙH [\B[\X[\Yۜ[]HH]XY\XHوX]\\[\X\[B[H[\\[۝Z[\˂[[\[][[[]Z\\[[\ZHX[[ܝ\8$H[YY۝\܈X[K\]H\H\[\[[B\X[YYوH]H[H]B[XZ[YH[YH[ܙ\ܚ]H[][H][ ܈^[\KBYY[\Hܚ]X[\۝[Z]B\Y[ۜ\[Y]BY\[\\ˈ[Z[\KY\[™\]Z\Y[][H][\\]\B[K[Z][ܙX\[H[]]Y \‚[[Y[[[\[HY][›و]Z[X[]H[X[Y [و\H[\YX[]H]\H\\\[YXXH[\H[[HU[]H[BݚY\ˈH]HY\Yۈ[Z[X\X\[][ۜ™܈\Y\[[\[B\X[[\X\KX[\HZ[[][Hو MHYX\ٝ[]Xۙ\\\HX\\Y ]H[ۛYH]BXH[YHH]H[H[ٝ[XYH؜]H[ۛHYBYX\܈\ˈ[X [YH\\XHY\\\H\[[š[\ N[۝YˈX[YYXB\X][ۜ]܈[[\X\BXKX\\[[]8&\ܝ[][HY]]ۙ\\H\YY[\\HZ[œXH][H۝^وH\X[[\X\H]\[\[H\YۙY܈XX[\]Y[\˂[YY H[[\وB]\H\HۛH][[ܙH]\KH\H[[YH\HB[[[X[܈XH[[[[۝^[Y[B\]Y[XHY\\˜[][YZ[\X[]ܚš[\X\H[\ܝ][[ܙKUX\[ۈXZ\\YܙHYY™]\HوZ\\X[]ܚ™[\H]Z\]H[\\HXBH]\HY\\˂Z[YXH]\H\˜[^\H[\\[\X[XHY[[Y[]Hۋ]XH[YHۈ[X\˜[[[[[^XY^\˂H[Y\]H]H[Bو ZYZH]H]B\Z[Y\X\\H\Έ]B[\]HH]^H\]Z\[Y[X\ۜ[\[X\XB[\\]\\[[[\ܝ[K^\[\]Z\Y[[H\Y\\[HX[YX\\X^H]B[\[ۙYܚY[[KLL[[[ [ L ̌ M MN
