• PCI Express Gen3 adapter capabilities
The server provides up to twelve PCIe Gen3 adapter slots. See "Installing an adapter" on page 83 for
more details and information about installing adapters.
• Redundant connection
The dual-port and quad-port Ethernet controller provides failover capability to a redundant Ethernet
connection with the applicable application installed. If a problem occurs with the primary Ethernet
connection and another Ethernet adapter is installed in the server, all Ethernet traffic that is associated
with the primary connection is automatically switched to an secondary Ethernet connection. If the
applicable device drivers are installed, this switching occurs without data loss and without user
intervention.
• Redundant cooling and optional power capabilities
The server supports up to 10 fan packs (two fans in each fan pack) with dual-motor, counter-rotating,
speed-controlled hot-swap fans, which provide redundancy and hot-swap capability for a full
configuration. The redundant cooling by the fans in the server enables continued operation if one of the
fan motors fails.
The server comes with one 900-watt or one 1400-watt hot-swap power supply. The server supports a
maximum of four 750-watt -48 volt to -60 volt dc power supplies, four 900-watt, or four 1400-watt hot-
swap power supplies.
For redundancy support, two or four 900-watt or 1400-watt power supplies must be installed in the server.
Two or four 900-watt or 1400-watt power supplies enables continued operation if any of the power
supplies fail or are taken off line. For the 750-watt -48 V dc power supply, the server only supports a four
power-supply configuration.
• Remote presence and blue-screen capture features
The remote presence and blue-screen capture features are integrated functions of the integrated
management module (IMM). The remote presence feature provides the following functions:
– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz, regardless of the system
state
– Remotely accessing the server, using the keyboard and mouse from a remote client
– Mapping the USB flash drive on a remote client, and mapping ISO and diskette image files as virtual
drives that are available for use by the server
– Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive
The blue-screen capture feature captures the video display contents before the IMM restarts the server
when the IMM detects an operating-system hang condition. A system administrator can use the blue-
screen capture feature to assist in determining the cause of the hang condition.
See "Using the remote presence and blue-screen capture features" on page 134 for additional
information.
• ServerGuide Setup and Installation DVD
The Lenovo ServerGuide™ Setup and Installation DVD, which you can download from the web, provides
programs to help you set up the server and install a Windows operating system. The ServerGuide program
detects installed optional hardware devices and provides the correct configuration programs and device
drivers. For more information about the ServerGuide Setup and Installation DVD, see "Using the
ServerGuide Setup and Installation DVD" on page 121.
• ServeRAID support
A ServeRAID™ adapter provides hardware redundant array of independent disks (RAID) support to create
configurations. The server comes with an integrated RAID controller, which provides RAID levels 0, 1 and
10. Additional optional RAID adapters, RAID cache cards, and Features on Demand software RAID are
available for RAID levels 5, 6, 50, and 60 upgrade.
