Dell MD3420

This Dell PowerVault MD3420 is a barebones 2U direct-attached storage array chassis with a 24-bay small-form-factor drive layout. It serves as the base enclosure for an MD3420 storage configuration, supporting the drive carriers, controller modules, power supplies, fans, and external host cabling used by the array. Final configuration depends on the installed controller modules, 2.5-inch drive type and capacity, SAS host connectivity, cabling, power-supply set, and management/firmware requirements for the attached server environment.
