DR Series Expansion Shelf

Each DR Series system appliance supports the installation and connection of up to two Dell PowerVault MD1200 data
storage expansion shelf enclosures. Each expansion shelf contains 12 physical disks in an enclosure, which provides
additional data storage capacity for the basic DR Series system. The supported data storage expansion shelves can be
added in 1 Terabyte (TB), 2 TB, or 3 TB hard drive capacities.
The physical disks in each expansion shelf are required to be Dell-certified Serial Attached SCSI (SAS) drives, and the
physical drives in the expansion shelf uses slots 1–11 configured as RAID 6, with slot 0 being a global hot spare (GHS).
When being configured, the first expansion shelf is identified as Enclosure 1 (in the case where two enclosures are
added, these would be Enclosure 1 and Enclosure 2). Adding an expansion shelf to support the DR Series system
requires a license. For more information, see
supported storage enclosures, see support.dell.com/manuals.
NOTE: The 300 Gigabyte (GB) drive capacity (2.7 TB) version of the DR Series system does not support the addition
of expansion shelf enclosures.
NOTE: If you are running a DR4000 system with an installed release of system software prior to 2.0, and you intend
to upgrade to release 2.0 system software and install an external expansion shelf (or shelves), Dell recommends
that you observe the following best practice sequence of operations to avoid any issues:
• Upgrade the DR4000 system with the release 2.0 system software
• Power off the DR4000 system (required for 2.0 with Dell OpenManage 7.1)
• Connect the external expansion shelf (or shelves) with cabling to the DR4000 system
• Power on the external expansion shelf (or shelves)
• Power on the DR4000 system
NOTE: If you install an expansion shelf enclosure to support a DR Series system, each shelf must use physical
disks that have a capacity equal to or greater than each DR Series system internal drive slot capacity (0–11) that
they are supporting.
