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 4.
• 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 Chinese Mainland, integrated TPM is not supported. However, customers in
Chinese Mainland can install a Trusted Cryptographic Module (TCM) adapter or a Lenovo-qualified TPM
adapter (sometimes called a daughter card).
• Large data-storage capacity and hot-swap capability
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. 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 comes with a QR code on the system service label, which is on the cover of the server, that you
can scan with 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.
• Active Energy Manager
Lenovo XClarity Energy Manager is a power and temperature management solution for data centers. You
can monitor and manage the power consumption and temperature of Converged, NeXtScale, System x,
ThinkServer and ThinkSystem servers, and improve energy efficiency with Lenovo XClarity Energy
Manager.
• Redundant networking connection
The Lenovo XClarity Controller provides failover capability to a redundant Ethernet connection with the
applicable application installed. If a problem occurs with the primary Ethernet connection, all Ethernet
traffic that is associated with the primary connection is automatically switched to the optional redundant
Ethernet 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 redundant cooling by the fans in the server enables continued operation if one of the fans fails.
• ThinkSystem RAID support
The ThinkSystem RAID 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.
