System x3850 X6 and x3950 X6 Types 3837 and 3839: Installation and Service Guide
The server provides up to twelve PCIe Gen3 adapter slots. See "Installing an
adapter" on page 84 for more details and information about installing adapters.
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.
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.
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 139
for additional information.
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.
