Acum doi ani, am realizat un lucru important: clien\u021bii sunt din ce \u00een ce mai interesa\u021bi de formele mici \u0219i de kilowa\u021bii redu\u0219i, a\u0219a c\u0103 am lansat o nou\u0103 gam\u0103 de produse \u2013 mini- \u0219i microDATA Center. Practic, am integrat \"min\u021bile\" unui centru de date complet \u00eentr-o mic\u0103 rack. Asemenea centrelor de date complete, acestea sunt echipate cu toate sistemele necesare, inclusiv componente pentru alimentare electric\u0103, climatizare, sisteme de securitate \u0219i stingerea incendiilor. De atunci, ne confrunt\u0103m adesea cu multe \u00eentreb\u0103ri legate de acest produs. Voi \u00eencerca s\u0103 r\u0103spund pe scurt la cele mai frecvente dintre ele. <\/p>\n

Cea mai important\u0103 \u00eentrebare este: de ce? De ce am f\u0103cut acest lucru \u0219i de ce sunt necesare microDATA Center? MicroDATA Center nu sunt, desigur, inven\u021bia noastr\u0103. Calculul la margine bazat pe mini- \u0219i microDATA Center este o tendin\u021b\u0103 global\u0103 \u00een cre\u0219tere, cunoscut\u0103 sub numele de Edge Computing. Aceasta este o tendin\u021b\u0103 logic\u0103 \u0219i evident\u0103: mutarea calculului mai aproape de locul de creare a informa\u021biei primare este o consecin\u021b\u0103 direct\u0103 a digitaliz\u0103rii afacerii: datele trebuie s\u0103 fie c\u00e2t mai aproape de client. Potrivit Gartner, aceast\u0103 pia\u021b\u0103 (calcul la margine) cre\u0219te \u00een medie cu 29,7% pe an \u0219i se va multiplica aproape de cinci ori p\u00e2n\u0103 \u00een 2023 \u2013 la 4,6 miliarde de dolari. \u0218i, odat\u0103 cu aceasta, cre\u0219te nevoia de infrastructur\u0103 fiabil\u0103 pentru echipamentele de calcul la margine.

\nCui \u00eei poate fi de folos? Celor care au nevoie de solu\u021bii unificate, care pot fi implementate rapid \u0219i la un cost redus \u00een sucursalele regionale, acolo unde este necesar un r\u0103spuns rapid al sistemelor informa\u021bionale, indiferent de calitatea canalelor de comunica\u021bie, de exemplu, pentru sucursalele \u00eendep\u0103rtate ale unei b\u0103nci sau ale unei companii petroliere. Majoritatea obiectivelor de extrac\u021bie a petrolului \u0219i gazelor (de exemplu, sondele) sunt situate la o distan\u021b\u0103 semnificativ\u0103 de birourile centrale, iar din cauza limitelor canalelor de comunica\u021bie, companiile trebuie s\u0103 proceseze cantit\u0103\u021bi mari de date chiar la locul \u00een care sunt generate. <\/p>\n

Capacitatea de procesare \u0219i agregare local\u0103 a datelor este un factor important, dar singurul aspect de interes pentru acest produs. MicroDC-urile sunt cel mai frecvent utilizate atunci c\u00e2nd o organiza\u021bie nu are posibilitatea (sau dorin\u021ba) de a apela la serviciile unui centru de date comercial sau de a construi unul propriu. Nu to\u021bi sunt preg\u0103ti\u021bi din diferite motive s\u0103 aleag\u0103 \u00eentre propriul centru de date \u0219i unul str\u0103in, \u00eentre proiectele pe termen lung de construc\u021bie a unui centru de date \u0219i solu\u021biile cloud publice. <\/p>\n

MicroDC este o alternativ\u0103 accesibil\u0103 pentru mul\u021bi, care permite evitarea construc\u021biei pe termen lung \u0219i costisitoare a unui centru de date propriu, p\u0103str\u00e2nd \u00een acela\u0219i timp controlul total asupra infrastructurii. Exist\u0103 interes \u00een r\u00e2ndul structurilor comerciale, \u00eentreprinderilor industriale \u0219i serviciilor guvernamentale pentru microDC-uri. Principalul motiv este tipizarea solu\u021biei. Aceasta se potrive\u0219te celor care doresc s\u0103 ob\u021bin\u0103 rapid rezultate \u0219i la un pre\u021b rezonabil - f\u0103r\u0103 lucr\u0103ri de proiectare \u0219i construc\u021bie, f\u0103r\u0103 preg\u0103tirea prealabil\u0103 a spa\u021biului \u0219i ob\u021binerea acestuia \u00een proprietate. <\/p>\n

Aici apare urm\u0103toarea \u00eentrebare: produsul este unul, iar motiva\u021bia pentru achizi\u021bionarea sa poate varia. Cum s\u0103 satisfacem clien\u021bii cu cerin\u021be diferite cu o singur\u0103 solu\u021bie? La 1,5 ani dup\u0103 \u00eenceperea v\u00e2nz\u0103rilor, vedem clar dou\u0103 cerin\u021be egale: una dintre ele este reducerea costului produsului, cealalt\u0103 - cre\u0219terea fiabilit\u0103\u021bii prin extinderea timpului de func\u021bionare autonom\u0103 \u0219i rezervare. Combinarea ambelor cerin\u021be \u00eentr-o singur\u0103 \"proxie\" este destul de complicat\u0103. O modalitate de a satisface at\u00e2t prima, c\u00e2t \u0219i a doua cerin\u021b\u0103 este de a construi toate sistemele ingineresti \u00een module deta\u0219abile, cu posibilitatea de demontare \u00een timpul utiliz\u0103rii. <\/p>\n

Abordarea modular\u0103 permite adaptarea la dorin\u021bele clientului \u00een cre\u0219terea gradului de rezervare sau, dimpotriv\u0103, \u00een reducerea general\u0103 a costului solu\u021biei. Pentru cei interesa\u021bi de reducerea costului, se pot elimina anumite sisteme ingineresti redundante din construc\u021bie sau le pot \u00eenlocui cu analogi mai simples. Iar pentru cei pentru care func\u021bionalitatea este mai important\u0103, dimpotriv\u0103 - se pot ad\u0103uga microDC-ului sisteme \u0219i servicii suplimentare. <\/p>\n

Un alt mare avantaj al modularit\u0103\u021bii este posibilitatea de scalare rapid\u0103. Dac\u0103 este necesar, infrastructura poate fi extins\u0103 prin ad\u0103ugarea de module noi. Acest lucru se face foarte u\u0219or, prin interconectarea dulapurilor \u00eentre ele.<\/p>\n

\u0218i, \u00een final, \u00eentrebarea-cheie care \u00eei intereseaz\u0103 mereu pe to\u021bi \u2013 despre loca\u021bie. Unde pot fi amplasate microdata centerele? \u00cen interior sau \u0219i afar\u0103? \u0218i care sunt cerin\u021bele pentru loca\u021bie? Teoretic, este posibil \u00een ambele locuri, dar exist\u0103 \u201enuan\u021be\u201d, deoarece echipamentele pentru solu\u021biile indoor \u0219i outdoor trebuie s\u0103 fie diferite. <\/p>\n

Dac\u0103 vorbim despre structuri standard, este mai bine s\u0103 le amplas\u0103m \u00een interior, nu \u00een exterior, deoarece sarcina IT necesit\u0103 o abordare specific\u0103. Asigurarea unui serviciu de calitate \u00een exterior, sub z\u0103pad\u0103 \u0219i ploaie, este dificil\u0103. Pentru amplasarea microdata centrelor este necesar\u0103 o \u00eenc\u0103pere care se potrive\u0219te dimensiunilor, unde pot fi trase linii de alimentare electric\u0103 \u0219i re\u021bele de cabluri, precum \u0219i instalate unit\u0103\u021bi externe de climatizare. Practic, asta e tot. Poate fi instalat direct \u00een atelier, \u00een depozit, \u00eentr-un spa\u021biu de birouri sau chiar \u00een birou. Nu este necesar\u0103 o infrastructur\u0103 ingineriasc\u0103 complex\u0103 pentru acest lucru. Cu alte cuvinte, se poate face \u00een orice birou standard. Dar, dac\u0103 totu\u0219i dori\u021bi foarte mult \u00een exterior, atunci sunt necesare modele speciale cu grad de protec\u021bie IP 65, care sunt potrivite pentru instalarea \u00een exterior. Ca solu\u021bie outdoor, avem \u0219i dulapuri climatizate. Acolo nu exist\u0103 astfel de sarcini, iar cerin\u021bele pentru redundan\u021b\u0103 \u0219i clim\u0103 sunt diferite.
