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
– Five to eight 3.5-inch hot-swap Serial Advanced Technology Attachment (SATA) or Serial Attached
SCSI (SAS) hard disk drives (SCSI is the acronym for Small Computer System Interface)
– Up to eight 2.5-inch hot-swap SAS hard disk drives
– Up to four 3.5-inch hot-swap SATA or SAS hard disk drives
– Up to four 3.5-inch non-hot-swap SATA hard disk drives
Note: For server models with more than four hard disk drives or models that use SAS hard disk drives,
there must be a required RAID card installed. See “RAID card” on page 33
.
• Optical drive
– Up to two 5.25-inch SATA optical drives (DVD-ROM or DVD Burner / CD-RW Rambo 8)
– The lower optical drive bay is installed with a 5.25-inch SATA optical drive (DVD-ROM or DVD Burner /
CD-RW Rambo 8). The upper optical drive bay is for a Removable Disk Technology (RDX) Universal

documentation that comes with the RDX USB drive bundle. In your server, the P6 power connector of the
power supply is for the RDX USB drive bundle. You can purchase this option directly from Lenovo. The
option name is Lenovo Removable Disk Technology (RDX) USB Drive Bundle. The RDX technology combines
the characteristics of tape backup with disk storage to help you protect and archive data.
