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.

(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.

8
ThinkSystem SR950 Setup Guide
runs as a virtual appliance that automates discovery, inventory, tracking, monitoring, and provisioning for
server, network, and storage hardware in a secure environment.
Lenovo XClarity Administrator provides a central interface to perform the following functions for all managed
endpoints:
Manage and monitor hardware. Lenovo XClarity Administrator provides agent-free hardware
management. It can automatically discover manageable endpoints, including server, network, and storage
hardware. Inventory data is collected for managed endpoints for an at-a-glance view of the managed
hardware inventory and status.
Configuration management. You can quickly provision and pre-provision all of your servers using a
consistent configuration. Configuration settings (such as local storage, I/O adapters, boot settings,
firmware, ports, and Lenovo XClarity Controller and UEFI settings) are saved as a server pattern that can
be applied to one or more managed servers. When the server patterns are updated, the changes are
automatically deployed to the applied servers.
Firmware compliance and updates. Firmware management is simplified by assigning firmware-
compliance policies to managed endpoints. When you create and assign a compliance policy to managed
endpoints, Lenovo XClarity Administrator monitors changes to the inventory for those endpoints and flags
any endpoints that are out of compliance.
When an endpoint is out of compliance, you can use Lenovo XClarity Administrator to apply and activate
firmware updates for all devices in that endpoint from a repository of firmware updates that you manage.
Operating System deployment. You can use Lenovo XClarity Administrator to manage a repository of
operating-system images and to deploy operating-system images to up to 28 managed servers
concurrently.
Service and support. Lenovo XClarity Administrator can be set up to collect and send diagnostic files
automatically to your preferred service provider when certain serviceable events occur in Lenovo XClarity
Administrator and the managed endpoints. You can choose to send diagnostic files to Lenovo Support
using Call Home or to another service provider using SFTP. You can also manually collect diagnostic files,
open a problem record, and send diagnostic files to the Lenovo Support Center.
Lenovo XClarity Administrator can be integrated into external, higher-level management and automation
platforms through open REST application programming interfaces (APIs). Using the REST APIs, Lenovo
XClarity Administrator can easily integrate with your existing management infrastructure. In addition, you can
automate tasks using the PowerShell toolkit or the Python toolkit.

Lenovo XClarity Energy Manager is a web-based power and temperature management solution designed for
data center administrators. It monitors and manages the power consumption and temperature of servers,
such as Converged, NeXtScale, System x, ThinkServer, and ThinkSystem servers, using the out-of-band
method. Lenovo XClarity Energy Manager models data center physical hierarchy and monitors power and
temperature at the server/group level. By analyzing monitored power and temperature data, Lenovo XClarity
Energy Manager greatly improves business continuity and energy efficiency.
With Lenovo XClarity Energy Manager, administrators can take control of power usage through improved
data analysis and lower the TCO (total cost of ownership). The tool optimizes data center efficiency by
allowing administrators to:
Monitor energy consumption, estimate power need, and re-allocate power to servers as needed via IPMI
or Redfish.
Track platform power consumption, inlet temperature, and component-level power consumption, such as
CPU and memory power consumption.
Visually check the layout of room, row and rack via 2D thermal map.
Show events and send e-mail or SNMP trap notifications when certain faults occur or certain thresholds
are reached.
Limit the consumed amount of energy of an endpoint by setting up policies.
Optimize energy efficiency by identifying hotspot or over-cooling servers to optimize cooling efficiency
and identifying low-usage servers to save energy.
Reduce the power consumption to the minimum level to prolong service time during emergency power
event (such as a data-center power failure).

Use the information in this section to learn about each of the components associated with your server.
Identifying your server
When you contact Lenovo for help, the machine type, model, and serial number information helps support
technicians to identify your server and provide faster service.
Figure 1 “Location of the ID label for the Lenovo ThinkSystem SR950” on page 15 shows the location of the
label containing the machine type, model, and serial number.
The model number, serial number, and a barcode of this server identification information are on the ID label
on the front of the server, as shown in the following illustration. You can also add other system information
labels to the front of the server in the customer label spaces (
1 in the following illustration).
Note: If any customer labels are placed on the removable front cover, make sure that the cover remains
installed on the same server where the labels were originally added.
