Light path diagnostics:
Light path diagnostics provides LEDs to help you diagnose problems. For more
information about the light path diagnostics, see
“Light path diagnostics panel” on page 16
and the
Problem Determination and Service Guide
on the IBM
System x Documentation
CD.
•
PCI adapter capabilities:
The server has two PCI interface slots (one supports low-profile cards, and one
supports half-length, full-height cards). Both slots can support PCI Express or PCI-X adapters through an
optional PCI riser card. See
“Installing an adapter” on page 66
for detailed information.
•
Active Energy Manager:
The IBM Active Energy Manager solution is an IBM Systems Director plug-in
that measures and reports server power consumption as it occurs. This enables you to monitor power
consumption in correlation to specific software application programs and hardware configurations. You
can obtain the measurement values through the systems-management interface and view them, using
IBM Systems Director. For more information, including the required levels of IBM Systems Director and
Active Energy Manager, see the IBM Systems Director documentation on the IBM
Systems Director CD
, or
http://www.ibm.com/systems/software/director/resources.html
•
Redundant connection:
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.
•
Redundant cooling and optional power capabilities:
The server supports a maximum of two 675-watt
or 460-watt hot-swap power supplies and six dual-motor hot-swap fans, which provide redundancy and
hot-swap capability for a typical configuration. The redundant cooling by the fans in the server enables
continued operation if one of the fans fails. The server comes with one 675-watt or 460-watt hot-swap
power supply and five fans.
You must install the sixth fan when you install the second microprocessor in the server. You can order the
second optional power supply for power redundancy.
Note:
You cannot mix 460-watt and 675-watt power supplies, high-efficiency and non-high-efficiency
power supplies, or ac and dc power supplies in the server.
•
ServeRAID support:
The ServeRAID adapter provides hardware redundant array of independent disks
(RAID) support to create configurations. The standard RAID adapter provides RAID levels 0, 1, and 1E. An
optional RAID adapter is available for purchase.
•
Systems-management capabilities:
The server comes with an integrated management module (IMM).
When the IMM is used with the systems-management software that comes with the server, you can
manage the functions of the server locally and remotely. The IMM also provides system monitoring, event
recording, and network alert capability. The system-management connector on the rear of the server is
dedicated to the IMM. The dedicated system-management connector provides additional security by
physically separating the management network traffic from the production network. You can use the
Setup utility to configure the server to use a dedicated systems-management network or a shared
network.
•
TCP/IP offload engine (TOE) support:
The Ethernet controllers in the server support TOE, which is a
technology that offloads the TCP/IP flow from the microprocessor and I/O subsystem to increase the
speed of the TCP/IP flow. When an operating system that supports TOE is running on the server and TOE
is enabled, the server supports TOE operation. See the operating-system documentation for information
about enabling TOE.
Note:
As of the date of this document, the Linux operating system does not support TOE.
