Tech Tips - Lenovo ThinkSystem SR950 V3 System Configuration Manual

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 Disk Operating System (DOS).
• 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 up to 128 TruDDR5 memory DIMMs operating at up to 4800 MHz. For more
information about the specific types and maximum amount of memory, see
page 3.
• 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.
Storage capacity is different depending on server model. See
more information.
• 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, 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,
and ThinkServer servers, and improve energy efficiency using 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
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, supporting RAID levels 0, 1, 5, 6, 10, 50, and 60.
