Drives overview

You can replace a drive in either a 12-drive, 24-drive, or 60-drive controller shelf or drive shelf.

12-drive or 24-drive shelves

The figures show how the drives are numbered in each type of shelf (the shelf's front bezel or end caps have been removed).

Note: Your E2812, E2824, EF280 storage array might include one or more SAS-2 legacy expansion drive trays, including the DE1600 12-drive tray, the DE5600 24-drive tray, or the DE6600 60-drive tray.

60-drive shelves

Both the E2860 controller shelf and the DE460C drive shelf consist of five drive drawers that each contain 12 drive slots. Drive drawer 1 is at the top, and drive drawer 5 is at the bottom.

For both an E2860 controller shelf drawer and a DE460C drive shelf drawer, drives are numbered from 0 to 11 in each drive drawer within the shelf.
