Termen datacenter omfattar den byggnad eller lokal d\u00e4r de centrala databehandlingssystemen \u00e4r placerade. Server<\/a> i ett f\u00f6retag, en organisation eller ett universitet. Av s\u00e4kerhetssk\u00e4l \u00e4r dessa enheter v\u00e4l skyddade och vanligtvis endast tillg\u00e4ngliga f\u00f6r en liten grupp personer med s\u00e4rskilt tillst\u00e5nd. Nedan kan du se de viktigaste detaljerna om ett datacenters struktur och uppgifter.<\/p>\n

Server (datacenter): f\u00f6retagets hj\u00e4rna
\nEtt datacenter (RZ) \u00e4r utformat f\u00f6r att bearbeta och hantera stora datam\u00e4ngder. De stora finans- och teknikkoncernerna har vanligtvis egna centra och ansvariga IT-avdelningar. Mindre f\u00f6retag eller till och med privatpersoner har m\u00f6jlighet att l\u00e4gga ut dessa tj\u00e4nster p\u00e5 entreprenad. De hyr ett RZ och k\u00f6per serverkapacitet f\u00f6r sina egna behov. Anslutningen mellan datacentret och kunden sker via s\u00e4kra dataledningar.
\nF\u00f6rdelen med ett datacenter \u00e4r att det tillhandah\u00e5ller en kraftfull infrastruktur som \u00e4ven omfattar drift av parallella system f\u00f6r att vara f\u00f6rberedd p\u00e5 fel. Str\u00f6mf\u00f6rs\u00f6rjningen \u00e4r ocks\u00e5 utrustad med tv\u00e5 oberoende str\u00f6mf\u00f6rs\u00f6rjningsenheter, s\u00e5 att driften kan forts\u00e4tta \u00e4ven om ett eventuellt fel uppst\u00e5r. F\u00f6r att minimera risken f\u00f6r fel installeras vanligtvis ocks\u00e5 generatorer f\u00f6r en avbrottsfri str\u00f6mf\u00f6rs\u00f6rjning (UPS). Ett h\u00f6gpresterande luftkonditioneringssystem \u00e4r ocks\u00e5 absolut n\u00f6dv\u00e4ndigt i ett datacenter f\u00f6r att f\u00f6rhindra att de h\u00f6gpresterande datorerna \u00f6verhettas.<\/p>\n

Organisation av RZ
\n- systemteknik
\nDet \u00e4r h\u00e4r som datacentrets h\u00e5rdvara sk\u00f6ts. Installationer och kablage utf\u00f6rs av specialiserade systemtekniker. Om ett fel uppst\u00e5r utf\u00f6r de ocks\u00e5 analyser i tid och vissa reparationer.
\n- systemf\u00f6rvaltning.
\nKonfigurationer utf\u00f6rs fr\u00e5n denna punkt s\u00e5 att datacentret k\u00e4nner igen och anv\u00e4nder nya enheter i drift. Beroende p\u00e5 datacentrets storlek finns \u00e4ven installation och administration av programvara h\u00e4r. Nya versioner av hj\u00e4lpprogram och versioner importeras till produktionen, vilka har testats och godk\u00e4nts av verksamheten i f\u00f6rv\u00e4g. M\u00e5nga f\u00f6retag har egna testmilj\u00f6er f\u00f6r detta \u00e4ndam\u00e5l.
\n- drift
\nDenna del omfattar operat\u00f6rernas drift och \u00f6vervakning av det faktiska datorsystemet i datacentret. P\u00e5 grund av de tekniska framstegen i operativsystemen har deras arbete f\u00f6r\u00e4ndrats avsev\u00e4rt. M\u00e5nga av de ursprungliga uppgifterna har blivit f\u00f6r\u00e5ldrade p\u00e5 grund av automatiseringen av processerna. M\u00e4nniskan m\u00e5ste dock forts\u00e4tta att s\u00e4kerst\u00e4lla viktiga funktioner i samspelet med maskinen, s\u00e4rskilt i h\u00e4ndelse av systemavvikelser eller fel (undantag).<\/p>\n

S\u00e4kerhet
\nSom du kan se \u00e4r s\u00e4kerheten h\u00f6gsta prioritet i ett datacenter, av f\u00f6rst\u00e5eliga sk\u00e4l med tanke p\u00e5 den dyra tekniken som installeras d\u00e4r. F\u00f6rutom restriktiva tilltr\u00e4desregler l\u00e4ggs stor vikt vid brandskyddet. Detta b\u00f6rjar redan med de strukturella \u00e5tg\u00e4rderna, genom att rummen \u00e4r f\u00f6rnuftigt separerade eller har dubbla v\u00e5ningar, vilket g\u00f6r det m\u00f6jligt att kyla maskinerna ytterligare underifr\u00e5n. H\u00f6gk\u00e4nsliga r\u00f6kdetekteringssystem anv\u00e4nds f\u00f6r att kunna uppt\u00e4cka en eventuell brand i ett tidigt skede. De anst\u00e4llda i ett RZ f\u00e5r ocks\u00e5 en aktiv utbildning i anv\u00e4ndningen av l\u00e4mpliga brandsl\u00e4ckare f\u00f6r att snabbt kunna reagera p\u00e5 mindre incidenter. Vid behov s\u00e4tts ocks\u00e5 automatiska sl\u00e4ckningssystem i drift, som bek\u00e4mpar branden genom att avge speciella sl\u00e4ckgaser.
\nOm ett datacenter skulle g\u00e5 helt s\u00f6nder i h\u00e4ndelse av en katastrof har m\u00e5nga operat\u00f6rer ett backup-datacenter redo, som \u00e4r bel\u00e4get p\u00e5 en annan plats. Backup-datacentret \u00e4r byggt p\u00e5 samma s\u00e4tt f\u00f6r att m\u00f6jligg\u00f6ra en s\u00e5 smidig drift som m\u00f6jligt. D\u00e4rf\u00f6r investerar man mycket i datacentrets s\u00e4kerhet, vilket \u00e4r helt logiskt n\u00e4r man bet\u00e4nker att till exempel en finanskoncern skulle vara tvungen att upph\u00f6ra med sin verksamhet helt och h\u00e5llet om det skulle uppst\u00e5 ett flera dagar l\u00e5ngt avbrott. Detta beror p\u00e5 att om handel och transaktioner inte skulle till\u00e5tas skulle det snabbt leda till en kollaps.<\/p>\n

Datas\u00e4kerhet
\nKund- och transaktionsuppgifter, vars v\u00e4rde \u00e4r n\u00e4stan lika stort som F\u00f6rlust<\/a> kan leda till en enorm prestigef\u00f6rlust och skada p\u00e5 ryktet. Kanske minns du ett exempel fr\u00e5n bankbranschen d\u00e4r kunduppgifter f\u00f6rlorades p\u00e5 grund av datast\u00f6ld, vilket ledde till stora snedvridningar p\u00e5 grund av f\u00f6rs\u00e4ljningen till skattemyndigheterna och de efterf\u00f6ljande kraven som detta utl\u00f6ste. Det \u00e4r uppenbart att inget f\u00f6retag kan och kommer att till\u00e5ta detta med sin Uppgifter<\/a> \u00e4r f\u00f6rem\u00e5l f\u00f6r handel. Sekretess och integritet f\u00f6r kund- och transaktionsuppgifter \u00e4r viktiga komponenter i dataskyddet. F\u00f6ljaktligen spenderas ocks\u00e5 mycket pengar p\u00e5 detta omr\u00e5de f\u00f6r att skydda mot obeh\u00f6rig \u00e5tkomst av anst\u00e4llda eller hackare genom krypteringsteknik och brandv\u00e4ggar.<\/p>","protected":false},"excerpt":{"rendered":"
