Features

Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of

your server. These design features make it possible for you to customize the system hardware to meet your

needs today and provide flexible expansion capabilities for the future.

Your server implements the following features and technologies:

• Lenovo XClarity Controller (XCC)

The Lenovo XClarity Controller is the common management controller for Lenovo ThinkSystem server

hardware. The Lenovo XClarity Controller consolidates multiple management functions in a single chip on

the server system board.

Some of the features that are unique to the Lenovo XClarity Controller are enhanced performance, higher-

resolution remote video, and expanded security options. For additional information about the Lenovo

XClarity Controller, see:

http://sysmgt.lenovofiles.com/help/topic/com.lenovo.systems.management.xcc.doc/product_page.html

• 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.

• Active Energy Manager

ThinkSystem SR950 Setup Guide

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 and optional power capabilities

The server supports a maximum of four 1100-watt (110V or 220V ac) or 1600-watt (220V ac) hot-swap

power supplies and six or twelve hot-swap fans, depending on the server configuration. The redundant

cooling by the fans in the server enables continued operation if a fan fails.

Note: You cannot mix power supply types in the server.

Lenovo XClarity Administrator

Lenovo XClarity Administrator is a centralized, resource-management solution that simplifies infrastructure

management, speeds responses, and enhances the availability of Lenovo server systems and solutions. It

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.

To obtain the latest version of the Lenovo XClarity Administrator, see:

https://datacentersupport.lenovo.com/documents/LNVO-LXCAUPD

Lenovo XClarity Energy Manager

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).

Chapter 2. Server components

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.

QR code

In addition, the service label that is located at the top rear of the compute system board inside the server,

provides a quick reference (QR) code for mobile access to service information. (You must disconnect all

server power cords before attempting to access the compute system board.) You can scan the QR code with

a mobile device using a QR code reader application and get quick access to the Service Information web

page (https://support.lenovo.com/p/servers/sr950). The Service Information web page provides additional

information for parts installation and replacement videos, and error codes for server support.

Figure 2. Service label and QR code

Network access label

The xClarity Controller (XCC) network access label is on the front of the server and must be removed before

operating the system. The label provides the default IPv4 host name and default IPv6 link local address of the

XCC.
