• 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/systems/x/hardware/enterprise/index.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 107).
• 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.
• Large system-memory capacity
The memory bus supports up to 384 GB of system memory when registered DIMMs are installed. The
server supports up to 64 GB if unbuffered DIMMs are installed. The memory controller supports error
correcting code (ECC) for up to 24 industry-standard PC3-8500 (DDR3-1066), PC3-10600 (DDR3-1333),
or PC3-12800 (DDR3-1600), DDR3 (third-generation double-data-rate), synchronous dynamic random
access memory (SDRAM) dual inline memory modules (DIMMs).
• 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 LEDs” on page 135.
• 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 information about installing DIMMs for memory mirroring, see “Memory
module installation” on page 60 for more information.
• Memory sparing
The server supports memory sparing. Memory sparing reserves memory capacity for failover in the
event of a DIMM failure, and the reserved capacity is subtracted from the total available memory.
Memory sparing provides less redundancy than memory mirroring does. If a predetermined threshold
of correctable errors is reached, the contents of the failing DIMM are copied to the spare memory, and
the failing DIMM or rank is disabled. To enable memory sparing through the Setup utility, select
System

Sparing . For information about installing DIMMs for memory
sparing, see “Memory module installation” on page 60.
• Mobile access to Lenovo Service Information website
The server provides a QR code on the system service label, which is on the cover of the server, that you
can scan using a QR code reader and scanner with a mobile device to get quick access to the Lenovo
Service Information website. The Lenovo Service Information website provides additional information for
parts installation and replacement videos, and error codes for server support. For the QR code, see QR
code information on page Chapter 1 “The Lenovo System x3500 M4 Type 7383 server” on page 1.
• Multi-core processors
The server supports up to two Intel Xeon™ E5-2600 series multi-core microprocessors. The server
comes with only one microprocessor installed.
• PCI adapter capabilities
