Zextras PowerStore, savuk\u0101rt, \u013cauj atteikties no LVM izmanto\u0161anas un, pievienojot parastus cietos diskus, palielina pieejamo apjomu.

Pl\u0101not\u0101 datu nes\u0113ju mai\u0146a ir diezgan izplat\u012bta prakse starp SaaS pakalpojumu sniedz\u0113jiem, kuriem ir viegl\u0101k pl\u0101not profilaktisko p\u0101rtraukumu un iepriek\u0161 inform\u0113t klientus, nek\u0101 ciest zaud\u0113jumus un saboj\u0101t savu reput\u0101ciju izsist\u0101 ciet\u0101 diska d\u0113\u013c.<\/p>\n
