EMC Vmax Architecture : Detailed ExplanationCurrently there are 3 types of EMC Vmax available EMC Vmax 10K,EMC Vmax 20K andEMC Vmax 40K !his arti"le des"ribin# the #eneral ar"hite"ture of Vmax models

$ymmetrix Vmax is EMC%s presti#ious produ"tCompared to the previous models,

Vmax has been optimi&ed for in"reased availability,performan"e and "apa"ity utili&ationon all tiers 'ith all ()*+ typesVmax%s enhan"ed devi"e "on#uration and repli"ationoperations results in easier,faster and more e-"ient mana#ement of lar#e virtual andphysi"al environment
