System x3650 M3 Types 4255, 7945, and 7949: Installation and User's Guide
The server comes with two integrated Broadcom Gigabit Ethernet controllers,
which support connection to a 10 Mbps, 100 Mbps, or 1000 Mbps network. For
more information, see "Configuring the Gigabit Ethernet controller" on page 172
The server supports up to eight or sixteen 2.5-inch hot-swap hard disk drives in
the hot-swap bays (depending on the model and optional devices installed).
With the hot-swap feature, you can add, remove, or replace hard disk drives
without turning off the server.
Light path diagnostics provides LEDs to help you diagnose problems. For more
information, see the section about light path diagnostics in the Problem
Determination and Service Guide.
The server supports up to four PCI interface slots. For more information, see
"Installing a PCI adapter" on page 53
Memory mirroring improves the availability of memory by writing information
to the main memory and redundant locations in a mirrored pair of DIMMs.
The addition of the optional Ethernet daughter card provides failover capability
to a redundant Ethernet connection with the applicable application installed. If a
problem occurs with the primary Ethernet connection and the optional Ethernet
daughter card is installed on the server, all Ethernet traffic that is associated
with the primary connection is automatically switched to the optional redundant
Ethernet daughter card connection. If the applicable device drivers are installed,
this switching occurs without data loss and without user intervention.
hot-swap fans, which provide redundant cooling. Redundant cooling enables
continued operation if one of the fans fails. The server supports a maximum of
two 675-watt or 460-watt hot-swap power supplies, which provide redundancy
and hot-swap capability for a typical configuration. The server comes with one
675-watt or 460-watt hot-swap power supply. You can order the second optional
power supply for power redundancy. If the maximum load on the server is less
than 675-watts (or 460-watt, depending on what kind of power supply you use)
and a problem occurs with one of the power supplies, the other power supply
can meet the power requirements.
Note: If the maximum load on the server is greater than 675-watts (or 460-watt,
depending on what kind of power supply you use) and a problem occurs with
one of the power supplies, Active Energy Manager can act to minimize the load
somewhat so that the server can function with the remaining power supply.
The server supports an internal ServeRAID SAS controller, which is required for
you to use the hot-swap hard disk drives and to create redundant array of
independent disks (RAID) configurations.
The server contains an integrated management module (IMM) which enables
you to manage the functions of the server locally and remotely. The addition of
the optional IBM Virtual Media Key provides remote presence and blue-screen
capture capability. The IMM also provides system monitoring, event recording,
and dial-out alert capability.
