Perform periodic physical inspection of your connections and cabling

Damaged cables and loose connections may cause functional issues with your storage solution.
Dell recommends a physical equipment audit two times a year or anytime after re-cabling or re-
deploying your storage hardware.

The PowerVault MD1xxx Family enclosures represent Dell JBOD offering. This includes both the
MD1000 and MD1120 enclosures (see Table 2). These are feature-optimized storage expansion
enclosures that use the latest industry standard storage interconnect technology, Serial Attached
SCSI (SAS). These enclosures support between 2 and 24 physical SAS drives. Along with Dell
host-based RAID controllers, PERC 5/E and PERC 6/E, the PowerVault MD1xxx Family
