Replacing hard drives

The Dell EMC Storage MD1280 enclosure supports hot‐swappable hard drives and supports up to 84 hard drives in 3.5-inch carriers, which

are installed in a two‐drawer, three‐row, 14‐column conguration. Hard drives are connected to a backplane by using Disk Drive in Carrier

(DDIC) hard drive carriers.

Numbering hard drive

Hard drives are numbered in the secli, starting with 0. Dell EMC Storage MD1280 DDIC slots are numbered 1–42 in drive drawer 0, from

front to back and left to right, and 43–84 in drive drawer 1.

NOTE

: The enumeration of hard drives in the secli software is zero-based. The physical enclosure enumerates hard drives

starting from 1.
