VMware : "Configuration Maximums in Numbers" by JPerf
21. január 2010
Autor: Julo Kováč
Vrámci opakovania na VCP-410 som sa rozhodol upraviť dokument od VMware "Configuration Maximums" pre "VMware® vSphere 4.0 and vSphere 4.0 Update 1" na svoj obraz, a dúfam, že každému, kto sa o túto disciplínu bližšie zaujíma bude na úžitok.
