Dell Compellent Hard Drives
Replace a Compellent hard drive with the same -CML part number, or failing that the same capacity, speed, interface and form factor. Compellent drives come in three spindle classes, 15K, 10K and 7.2K nearline SAS, in 2.5-inch and, for 15K and nearline, 3.5-inch sizes, running at 6Gb/s or 12Gb/s and with self-encrypting (SED) versions. Each drive is tested before it ships, and drives in stock are eligible for same-day dispatch.

Compellent drive types
Compellent SC Series hard drives fall into three spindle classes, and Dell's Storage Center groups drives by speed into as many as three tiers, from the fastest (Tier 1) to the slowest (Tier 3):
| Drive type | Form factors | SAS interface | Typical Storage Center tier (Dell) |
|---|---|---|---|
| 15K SAS | 2.5-inch and 3.5-inch | 6Gb/s or 12Gb/s | Tier 1 when the system has no SSDs, otherwise Tier 2 or 3 |
| 10K SAS | 2.5-inch | 6Gb/s or 12Gb/s | Tier 2 |
| 7.2K nearline SAS | 3.5-inch, with some 2.5-inch models | 6Gb/s or 12Gb/s | Tier 3, or Tier 1 only when it is the only drive type |
Drive types mix within one system because each type lands in its own tier. Dell's SC Series RAID paper also has the array assign hot spares itself: one spare for every drive class in 2U enclosures, and one for every 21 drives in 5U enclosures.
Why Compellent arrays take -CML drives
Compellent drives are bought by part number because Dell specifies the drives its SC Series systems run: the SC5020 owner's manual states that the system ships with, and supports, Dell Enterprise Plus drives. The -CML suffix marks the Dell drive versions sold for Compellent SC Series arrays, so a matching -CML part number is the safest replacement for a failed drive. If the original part number is not listed, send it with your quote request and we will identify the closest match by capacity, speed and interface.
Enclosures and bay formats
Bay size is fixed by the enclosure, so check it before ordering:
| Enclosure (Dell) | Drive bays |
|---|---|
| SC5020 and SC7020 storage systems | Up to 30 internal 2.5-inch SAS drives |
| SC420 expansion enclosure | Up to 24 hot-swappable 2.5-inch 12Gbps SAS drives |
| SC400 expansion enclosure | Up to 12 hot-swappable 3.5-inch 12Gbps SAS drives |
| SC460 expansion enclosure | Up to 60 3.5-inch 7.2K 12Gbps SAS drives in 4U |
On an SC5020, one SAS chain takes up to sixteen SC400, eight SC420 or three SC460 enclosures, and the system supports up to 222 drives in total. Drive trays are listed separately under Drive Caddies and Trays.
Other Compellent parts
SSD tiers for the same arrays are on Compellent SSDs, controllers on Compellent Controllers, and complete systems on Dell Compellent arrays. For how these SAS drives differ from SATA drives, see SAS vs SATA.
