Dell DR series, Administrator'S Manual

Page: 29 / 188

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 DR Series system with an installed release of system software prior to 2.1, and you
intend to upgrade to release 3.x system software and add an external expansion shelf (or shelves), Dell
recommends that you observe the following best practice sequence of operations to avoid any issues:
• Upgrade the DR Series system with the release 3.x system software
• Power off the DR Series system
• Connect the external expansion shelf (or shelves) with cabling to the DR Series system
• Power on the external expansion shelf (or shelves)
• Power on the DR Series 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.
