Internal drives
Internal drives are devices that your server uses to read and store data. The internal drives supported
by your server vary by model.
• Hard disk drive
Note:
You can install Serial Advanced Technology Attachment (SATA) hard disk drives, Serial Attached
SCSI (SAS) hard disk drives (SCSI is the acronym for Small Computer System Interface), and solid-state
drives into the same server.
– Up to eight 3.5-inch hot-swap SATA hard disk drives, SAS hard disk drives, or solid-state drives
– Up to eight 2.5-inch hot-swap SATA hard disk drives, SAS hard disk drives, or solid-state drives
– Up to sixteen 2.5-inch hot-swap SATA hard disk drives or SAS hard disk drives. If you install 2.5-inch
solid-state drives and hard disk drives into the same server, you can install up to two 2.5-inch
solid-state drives for this configuration.
– Support PCI Express solid-state drives
The following server models also are available:
– Server models without hard disk drives or solid-state drives
– Server models without hard disk drives, solid-state drives, backplanes, RAID cards, and related cables
• Optical drive
– One slim SATA optical drive in some models
External drives
If your server has a Host Bus Adapter installed, an external tape drive can be connected to store data on
tapes. To connect an external tape drive, see “Connecting an external tape drive” on page 139.
