NetApp Hard Drives
Order NetApp hard drives by the X-part number of the drive you are replacing, because NetApp sells each drive under its own X-number. NetApp drives come as 10K and 15K SAS performance drives, 7.2K SAS and SATA capacity drives, NSE drives with NetApp Storage Encryption, and tandem carriers, which NetApp's DS4486 shelf uses to hold two drives per carrier. NetApp drives are tested in-house when they arrive and again before dispatch.

NetApp drive types
The X-number on the failed drive is the safest match because it fixes the capacity, speed, interface and carrier together; the drive types it can point to are these.
| Drive type | Interface | Matching rule |
|---|---|---|
| Performance SAS, 10K or 15K | SAS at 3, 6 or 12Gb/s | Match the X-number and the carrier size |
| Capacity SAS, 7.2K | SAS at 6 or 12Gb/s | Match the X-number |
| Capacity SATA, 7.2K | SATA | Match the X-number |
| NSE encrypting drive | SAS | Replace only with another NSE drive |
| Tandem carrier, two 7.2K drives (DS4486 shelf) | 6Gb/s | Match the X-number of the carrier |
NSE drives need NSE partners. For the drives NetApp calls FIPS drives, its knowledge base states that all drives, including those in the HA pair, must be NSE drives, and NSE and non-NSE drives cannot be mixed; so an NSE drive replaces an NSE drive, and a standard drive replaces a standard one. SSDs for NetApp systems are on NetApp SSDs, other array drives under Storage Array Hard Drives, and SAS vs SATA explains the two interfaces.
NetApp disk shelves and the drives they hold
The shelf fixes the drive form factor and the SAS generation, so check the shelf model as well as the X-number. NetApp's shelf documents describe the shelves this way.
| Shelf | I/O module | Drives (NetApp documentation) |
|---|---|---|
| DS4243 | IOM3 | Up to 24 drives |
| DS4246 | IOM6 | Up to 24 drives |
| DS212C | IOM12 | 3.5-inch drives, or 2.5-inch drives in carriers |
| DS224C | IOM12 | Up to 24 drives, all 2.5-inch |
| DS460C | IOM12 | 60 drives in drawers of 12, in 3.5-inch or 2.5-inch carriers |
NetApp does not support mixing IOM3 and IOM6 modules in one DS4243 or DS4246 shelf, and shelves with IOM12 modules must sit in a stack of their own. Drives for servers rather than NetApp shelves are on server hard drives.
NetApp hard drive questions
- Can NetApp drives be used in a regular server?
- Not as they come out of a NetApp system. NetApp's knowledge base shows ONTAP drives running at 520 bytes per sector, and ONTAP marks a drive set to 512 bytes per sector as failed, so the sector format belongs to the platform the drive runs in. Moving a drive between a NetApp shelf and a general-purpose server means changing that format first. For a NetApp system, order by X-number; for a server, buy a server drive.
- How do I find which drives my NetApp shelf supports?
- Look the shelf up in the NetApp Hardware Universe. NetApp's shelf guides say a replacement drive must be supported by the shelf and point to the Hardware Universe for the supported drives of each configuration, and its hot-add procedure uses the same tool to confirm the ONTAP version a shelf, its modules and its drives need. NetApp also advises installing the latest Disk Qualification Package before a drive swap, so the system recognizes newly qualified drives.
