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

–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 Serial Bus (USB) drive bundle.

For the location information about the internal drives or drive bays, see “Server components” on page

25.For information about the RDX USB drive bundle and instructions on how to install it, refer to the

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.

Expansion slots

The server has four expansion slots on the system board. For detailed information, see “System board components” on page 42.

Input/Output (I/O) features

•One Video Graphics Array (VGA) DB-15 connector on the rear panel

•Six USB 2.0 connectors (two on the front panel and four on the rear panel)

•Two RJ-45 Ethernet connectors on the rear panel

•Two serial connectors (one fully-functional serial connector on the rear panel and one internal serial connector on the system board for optional use)

For the location information about the connectors, refer to the related topic in “Locations” on page 13.

Video subsystem

An integrated graphics controller in the Baseboard Management Controller (BMC) chip on the system board to support a VGA DB-15 connector on the rear panel for connecting video devices

Ethernet connectivity

The server comes with an integrated Intel Gigabit Ethernet controller as well as an Ethernet physical layer (PHY) of the Open Systems Interconnection model (OSI model). They provide the server with the ability to support two Ethernet connectors on the rear panel with 10 Mbps, 100 Mbps, or 1000 Mbps network connectivity. For more information, see “Rear view of the server” on page 19.
