• UEFI-compliant server firmware
Lenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) 2.5 compliant. UEFI
replaces BIOS and defines a standard interface between the operating system, platform firmware, and
external devices.
Lenovo ThinkSystem servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support DOS (Disk Operating System).
• Active Memory
The Active Memory feature improves the reliability of memory through memory mirroring. Memory
mirroring mode replicates and stores data on two pairs of DIMMs within two channels simultaneously. If a
failure occurs, the memory controller switches from the primary pair of memory DIMMs to the backup pair
of DIMMs.
• Large system-memory capacity
The server supports synchronous dynamic random-access memory (SDRAM) registered dual inline
memory modules (DIMMs) with error correcting code (ECC). For more information about the specific types
and maximum amount of memory, see "Specifications" on page 3.
• Integrated network support
The server comes with one of several types of LOM adapter, which supports connection to one of the
following network types: 10GBASE-T (2–port or 4–port), 1GBASE-T (2–port or 4–port), or 2x 10Gb SFP+
(2–port or 4–port). An ML2 form factor network adapter is also supported.
• 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.
Note: For customers in the People's Republic of China, TPM is not supported. However, customers in the
People's Republic of China can install a Trusted Cryptographic Module (TCM) adapter (sometimes called
a daughter card).
• Large data-storage capacity and hot-swap capability
The server models support a maximum of 24 2.5-inch hard disk drives that are of the hot-swap Serial
Attached SCSI (SAS) or hot add/remove NVMe types (depending on system configuration).
With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.
• Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems and an LCD information display
panel that provides additional diagnostic information. For more information about the light path
diagnostics, see Light path diagnostics panel and Light path diagnostics LEDs.
• Mobile access to Lenovo Service Information website
The server provides a QR code on each system board 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, replacement videos, and
error codes for server support. See "QR code" on page 15 for information about accessing the QR code
label.
