Partial Population Configurations - Western Digital Ultrastar Data60 User Manual

User Guide
5.5.1 Partial Population Configurations
The Ultrastar Data60 supports partially-populated configurations that allow a user to increase the size of
storage based on their needs. There are specific requirements that must be followed to ensure that the
enclosure functions properly during operation. Partial population configurations that do not comply with
the requirements listed in this section may result in enclosure performance issues. The following section
details the requirements for HDD and HDD/SSD based configurations.
Minimum HDD Partial Population
The enclosure supports a minimum of 24 SAS or SATA HDDs for a partially-populated enclosure. The
enclosure does not support a mix of SAS and SATA drives. The enclosure must be populated starting with
the drives closest to the rear of the enclosure and work towards the front of the enclosure. If more drives
are installed into the enclosure, any unfinished rows must be completed with drive blanks. The image
below details the minimum required configuration for an HDD only configuration.
