5086346.
v Integrated network support
The server comes with an integrated Emulex BE3 Ethernet controller that
supports embedded dual-port 1 Gb connections and the optional dual-port 10
Gb-T and the optional dual-port 10Gb SFP+Fiber Ethernet adapters. The
Ethernet controller supports connection to a 10 Mbps, 100 Mbps, or 1000 Mbps
network. For more information, see “Configuring the Ethernet controller” on
page 156.
v Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores
private and public secure keys. It provides the hardware support for the Trusted
Computing Group (TCG) specification. You can download the software to
support the TCG specification, when the software is available. See
http://www.ibm.com/servers/eserver/xseries/scalable_family.html for details
about the TPM implementation. You can enable TPM support through the Setup
utility under the System Security menu choice (see“Using the Setup utility” on
page 142).
v Large data-storage capacity and hot-swap capability
The server can support a maximum of sixteen 2.5-inch drives, thirty-two 32
1.8-inch drives, or a combination of both 2.5-inch and 1.8-inch drives when you
use the supported SAS/SATA backplane configurations. The server supports
2.5-inch hot-swap Serial Attached SCSI (SAS) hard disk drives or hot-swap Serial
ATA (SATA) hard disk drives, 2.5-inch hot-swap solid state drives (SSD), or
1.8-inch hot-swap solid state drives.
With the hot-swap feature, you can add, remove, or replace hard disk drives
without turning off the server.
v Large system-memory capacity
The server can support up to 1.5 TB of system memory. The server base system
board provides 24 dual inline memory module (DIMM) connectors for up to 768
GB of memory. For additional memory capacity, an optional microprocessor and
memory expansion tray is available for purchase that provides 24 DIMMs for up
to 768 GB of additional memory (depending on the DIMM size) and two
additional microprocessor sockets. The server memory controller supports error
correcting code (ECC) for up to 48 industry-standard PC3-12800R 1600 MHz,
PC3L-10600R-999 1333 MHz or PC3L-10600 1333 MHz Load Reduced (LR),
single-rank, dual-rank, or quad-rank, DDR3 (third-generation double-data-rate),
registered, synchronous dynamic random access memory (SDRAM) DIMMs.
v Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more
information about light path diagnostics and the LEDs, see “Light path
diagnostics” on page 19 and “Light path diagnostics LEDs” on page 174.
v Memory mirroring
Memory mirroring provides a redundant copy of all code and data that are
addressable in the configured memory map. Through the microprocessor
memory controller chip set, memory mirroring replicates and stores data across
DIMMs on two or four memory channels simultaneously. If a failure occurs, the
memory controller switches from the DIMMs on the primary channel to the
DIMMs on the backup channel. To enable memory mirroring through the Setup
utility, select System Settings → Memory → Memory Mode → Mirroring. For
