For more information about System Guard, see https://pubs.lenovo.com/xcc2/NN1ia_c_systemguard

Because Lenovo XClarity Administrator does not require any agent software to be installed on the managed endpoints, there are no CPU cycles spent on agent execution, and no memory is used, which means that up to 1GB of RAM and 1 - 2% CPU usage is saved, compared to a typical managed system where an agent is required.

Lenovo XClarity Administrator is an optional software component for the SR680a V3 B200. The software can be downloaded and used at no charge to discover and monitor the SR680a V3 B200 and to manage firmware upgrades.

If software support is required for Lenovo XClarity Administrator, or premium features such as configuration management and operating system deployment are required, Lenovo XClarity Pro software subscription should be ordered. Lenovo XClarity Pro is licensed on a per managed system basis, that is, each managed Lenovo system requires a license.

The following table lists the Lenovo XClarity software license options.

For more information, refer to the Lenovo XClarity Administrator Product Guide:
http://lenovopress.com/tips1200

For more information about all the available Lenovo XClarity Integrators, see the Lenovo XClarity Administrator Product Guide: https://lenovopress.com/tips1200-lenovo-xclarity-administrator

Topics in this section:

• Security features
• Platform Firmware Resiliency - Lenovo ThinkShield

Security features

The SR680a V3 with B200 server offers the following electronic security features:

• Secure Boot function of the Intel processor
• Support for Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) - see the Platform Firmware Resiliency section
• Firmware signature processes compliant with FIPS and NIST requirements
• System Guard (part of XCC Platinum) - Proactive monitoring of hardware inventory for unexpected component changes
• Administrator and power-on password
• Integrated Trusted Platform Module (TPM) supporting TPM 2.0
• Self-encrypting drives (SEDs) with support for enterprise key managers

The server is NIST SP 800-147B compliant.

Platform Firmware Resiliency - Lenovo ThinkShield

Lenovo's ThinkShield Security is a transparent and comprehensive approach to security that extends to all dimensions of our data center products: from development, to supply chain, and through the entire product lifecycle.

The ThinkSystem SR680a V3 with B200 includes Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which enables the system to be NIST SP800-193 compliant. This offering further enhances key platform subsystem protections against unauthorized firmware updates and corruption, to restore firmware to an integral state, and to closely monitor firmware for possible compromise from cyber-attacks.

PFR operates upon the following server components:

• UEFI image – the low-level server firmware that connects the operating system to the server hardware
• XCC image – the management “engine” software that controls and reports on the server status separate from the server operating system
• FPGA image – the code that runs the server’s lowest level hardware controller on the motherboard

The Lenovo Platform Root of Trust Hardware performs the following three main functions:

• Detection – Measures the firmware and updates for authenticity
• Recovery – Recovers a corrupted image to a known-safe image
• Protection – Monitors the system to ensure the known-good firmware is not maliciously written

These enhanced protection capabilities are implemented using a dedicated, discrete security processor whose implementation has been rigorously validated by leading third-party security firms. Security evaluation results and design details are available for customer review – providing unprecedented transparency and assurance.

The SR680a V3 B200 includes support for Secure Boot, a UEFI firmware security feature developed by the UEFI Consortium that ensures only immutable and signed software are loaded during the boot time. The use of Secure Boot helps prevent malicious code from being loaded and helps prevent attacks, such as the installation of rootkits. Lenovo offers the capability to enable secure boot in the factory, to ensure end-to-end protection. Alternatively, Secure Boot can be left disabled in the factory, allowing the customer to enable it themselves at a later point, if desired.

The following table lists the relevant feature code(s).

The SR680a V3 with B200 installs in a standard 19-inch rack cabinet. It is supported installed on a static L-shaped rail kit as listed in the following table.

The figure below shows the components of the rail kit.

Figure 8. ThinkSystem Toolless Fixed Rail Kit

Configuration rules:

• A maximum of 5x SR680a V3 with B200 servers can be installed in a single rack cabinet (42U or 48U)
• The rail kit is included in CTO orders by default, but can be removed if desired
• A cable management arm (CMA) is not supported

The following table summarizes the rail kit features and specifications.

Considering the weight of the trays in the server, an onsite material lift is required to allow service by a single person. If you do not already have a material lift available, Lenovo offers the Genie Lift GL-8 material lift as configurable option to the rack cabinets. Ordering information is listed in the following table.

Note: If neither the Genie Lift GL-8 nor the ServerLift SL-350x is available onsite when onsite service is required, the customer will be responsible for getting the system to a suitable work surface (with access to power) prior to service technician arrival and returning the system to the rack when service is complete prior to service technician departure.

The SR680a V3 with B200 supports the following operating systems:

• Red Hat Enterprise Linux 9.5
• Ubuntu 22.04 LTS 64-bit
• Ubuntu 24.04 LTS 64-bit
