server enables continued operation if one of the fans fails. The server comes
with one 750-watt or 900-watt hot-swap power supply and two fans.
You must install fan 2 when you install the second microprocessor in the server.
You can order the optional fan 4, 5, and 6 for cooling redundancy. You can order
the second optional power supply for power redundancy.
Notes:
1. You cannot mix 750-watt and 900-watt power supplies in the server.
2. The server is not running in power redundant mode with two 225W GPUs
installed, two 900-watt power supplies are required.
v
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 10. An optional RAID adapter is available for purchase.
v
Systems-management capabilities
The server comes with an integrated management module II (IMM2). When the
IMM2 is used with the systems-management software that comes with the server,
you can manage the functions of the server locally and remotely. The IMM2 also
provides system monitoring, event recording, and network alert capability. The
system-management connector on the rear of the server is dedicated to the
IMM2. 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.
Reliability, availability, and serviceability
Three important computer design features are reliability, availability, and
serviceability (RAS). The RAS features help to ensure the integrity of the data that
is stored in the server, the availability of the server when you need it, and the ease
with which you can diagnose and correct problems.
Your server has the following RAS features:
v
3-year parts and 3-year labor limited warranty for machine type 7383
v
Automatic error retry and recovery
v
Automatic restart on nonmaskable interrupt (NMI)
v
Automatic restart after a power failure
v
Backup basic input/output system switching under the control of the Integrated
Management Module II (IMM2)
v
Built-in monitoring for fan, power, temperature, voltage, and power-supply
redundancy
v
Chipkill memory protection
v
Diagnostic support for ServeRAID and Ethernet adapters
v
Error correcting code (ECC) L2 cache and system memory
v
Simple-swap cooling fans with speed-sensing capability
v
Hot-swap hard disk drives
v
Information and light path diagnostics LED panels
v
Integrated Management Module II (IMM2)
v
Menu-driven setup, system configuration, and redundant array of independent
disks (RAID) configuration programs
v
Microprocessor built-in self-test (BIST), internal error signal monitoring,
configuration checking, and microprocessor and voltage regulator module failure
identification through light path diagnostics
v
Memory mirrored channel support (memory mirrored channel are mutually
exclusive of each other)
