U\u017e jste se ur\u010dit\u011b setkali s pojmem Object Storage. V pod\u00e1n\u00ed VMware tu m\u00e1me aktu\u00e1ln\u011b dva z\u00e1stupce, kter\u00e9 m\u016f\u017eeme takto ozna\u010dovat. Jedn\u00e1 se o vSAN a vVol (Virtual Volumes). Pozor nepl\u00e9st s AppVolumes, k tomu se n\u011bkdy p\u0159\u00ed\u0161t\u011b dostanu tak\u00e9.<\/p>\n

Oba dva z\u00e1stupci pracuj\u00ed na podobn\u00e9m pricipu. K jednotliv\u00fdm soubor\u016fm, nebo skupin\u00e1m soubor\u016f se p\u0159istupuje jako k objekt\u016fm.<\/p>\n

Co to objekt ale je?<\/h2>\n

Je to obdobn\u00e9 jako u programov\u00e1n\u00ed. Objekt je prvek, kter\u00fd m\u00e1 krom\u011b hodnoty, tak\u00e9 n\u011bjak\u00e9 vlastnosti a k n\u011bmu vzta\u017een\u00e9 metody (funkce).<\/p>\n

Kdy\u017e to tedy p\u0159evedeme na na\u0161e dva reprezentaty \u00falo\u017ei\u0161t\u011b, tak se budeme tak\u00e9 bavit o objektech, jeliko\u017e ka\u017ed\u00fd m\u00e1 n\u011bjak\u00e9 svoje hodnoty (samotn\u00e1 data, kter\u00e1 ukl\u00e1d\u00e1me) a vlastnosti, jako jsou datum vytvo\u0159en\u00ed, dostupnost, v\u00fdkon apod.<\/p>\n

Jak objekt \u0159\u00eddit?<\/h2>\n

T\u00edm se dost\u00e1v\u00e1me k tomu, jak takov\u00fd objekt m\u016f\u017eeme \u0159\u00eddit. Ve vSphere prost\u0159ed\u00ed k tomu vyu\u017e\u00edv\u00e1me techniku Storage Policy Based Management. Toto je tu ji\u017e n\u011bjaou dobu a ze za\u010d\u00e1tku to bylo v\u00edce reaktivn\u00ed, ne\u017e proaktivn\u00ed. Za\u010dalo se s pomoc\u00ed tag\u016f jednotliv\u00fdch datastore a na z\u00e1klad\u011b toho, jak jste nastavili politiku pro konkr\u00e9tn\u00ed VM se v\u00e1m doporu\u010dily Datastore, kter\u00e9 tyto tagy spl\u0148ovaly.<\/p>\n

Postupem \u010dasu se k tomu p\u0159idali i vendo\u0159i, kte\u0159\u00ed obohatili tagy i o n\u011bco smyslupln\u011bj\u0161\u00edho a to jsou r\u016fzn\u00e9 parametry pole na kter\u00fdch se dan\u00fd datastore nach\u00e1z\u00ed. SSD\/HDD, RAID, HA, RPM (ot\u00e1\u010dky disk\u016f), velikost cache \u2026.<\/p>\n

T\u00edm jste mohli „\u0159\u00eddit“, na jak v\u00fdkonn\u00e9m poli\/\u010d\u00e1sti pole, se bude VM nach\u00e1zet.<\/p>\n

Ale abychom se dostali k trochu proaktivn\u011bj\u0161\u00edmu \u0159e\u0161en\u00ed, tak je t\u0159eba se p\u0159en\u00e9st do skute\u010dn\u00e9ho Object Storage.<\/p>\n
