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 ST50 V3 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 ST50 V3 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 ambient temperature must be 35°C or lower if the server has any of the following components:

• M.2 drives (960 GB or below)

NOTE

When the ambient temperature is greater than the supported temperature, the server will shut down. The server will not power on again until the ambient temperature falls within the supported temperature range.

Acoustical noise emissions

The server has the following acoustic noise emissions declaration:

• Sound power level (L_WAd)
  • Idling: 3.4 Bel (Typical), 4.0 Bel (Max.)
  • Operating 1: 3.4 Bel (Typical), 4.0 Bel (Max.)
  • Operating 2: 4.8 Bel (Typical), 5.4 Bel (Max.)
• Sound pressure level (L_pAm):
  • Idling: 20.3 dBA (Typical), 27.6 dBA (Max.)
  • Operating 1: 20.3 dBA (Typical), 27.6 dBA (Max.)
  • Operating 2: 35.1 dBA (Typical), 40.6 dBA (Max.)

NOTE

• These sound levels were measured in controlled acoustical environments according to procedures specified by ISO 7779 and are reported in accordance with ISO 9296. Testing was conducted at 23°C ± 2°C to align with ISO7779 procedures.

• Idling mode is the steady state in which the server is powered on but not operating any intended function. Operating mode 1 is 50% CPU TDP. Operating mode 2 is 100% CPU TDP.

• The declared acoustic sound levels are based on the following configurations, which may change depending on configuration/conditions:
  • Typical: 1x 80W CPU, 1x 16GB DIMM, 1x 3.5" HDD, 1x Slim SATA ODD, 1x 300W fixed PSU
  • Maximum: 1x 95W CPU, 4x 32 GB DIMM, 3x 3.5" HDD, 1x 2.5" SSD, 1x Slim SATA ODD, 1x 5350-8i RAID, 1x 1G NIC, 1x 500W fixed PSU
• Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employee's location in relation to the equipment. Further, compliance with such government regulations depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.

The following specifications indicate the limits of particulates that the system can tolerate:

• Reactive gases:
  • The copper reactivity level shall be less than 200 Angstroms per month (Å/month)
  • The silver reactivity level shall be less than 200 Å/month
• Airborne particulates:
  • The room air should be continuously filtered with MERV 8 filters.
  • Air entering a data center should be filtered with MERV 11 or preferably MERV 13 filters.
  • The deliquescent relative humidity of the particulate contamination should be more than 60% RH
  • Environment must be free of zinc whiskers

For additional information, see the Specifications section of the documentation for the server, available from the Lenovo Documents site, https://pubs.lenovo.com/

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spare parts.

Lenovo Services is a dedicated partner to your success. Our goal is to reduce your capital outlays, mitigate your IT risks, and accelerate your time to productivity.

Here’s a more in-depth look at what we can do for you:

• Asset Recovery Services

  Asset Recovery Services (ARS) helps customers recover the maximum value from their end-of-life equipment in a cost-effective and secure way. On top of simplifying the transition from old to new equipment, ARS mitigates environmental and data security risks associated with data center equipment disposal. Lenovo ARS is a cash-back solution for equipment based on its remaining market value, yielding maximum value from aging assets and lowering total cost of ownership for your customers. For more information, see the ARS page, https://lenovopress.com/lp1266-reduce-e-waste-and-grow-your-bottom-line-with-lenovo-ars.

• Assessment Services

  An Assessment helps solve your IT challenges through an onsite, multi-day session with a Lenovo technology expert. We perform a tools-based assessment which provides a comprehensive and thorough review of a company's environment and technology systems. In addition to the technology based functional requirements, the consultant also discusses and records the non-functional business requirements, challenges, and constraints. Assessments help organizations like yours, no matter how large or small, get a better return on your IT investment and overcome challenges in the ever-changing technology landscape.

• Design Services

  Professional Services consultants perform infrastructure design and implementation planning to support your strategy. The high-level architectures provided by the assessment service are turned into low level designs and wiring diagrams, which are reviewed and approved prior to implementation. The implementation plan will demonstrate an outcome-based proposal to provide business capabilities through infrastructure with a risk-mitigated project plan.

• Basic Hardware Installation

  Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.

• Deployment Services

  When investing in new IT infrastructures, you need to ensure your business will see quick time to value with little to no disruption. Lenovo deployments are designed by development and engineering teams who know our Products & Solutions better than anyone else, and our technicians own the process from delivery to completion. Lenovo will conduct remote preparation and planning, configure & integrate systems, validate systems, verify and update appliance firmware, train on administrative tasks, and provide post-deployment documentation. Customer’s IT teams leverage our skills to enable IT staff to transform with higher level roles and tasks.

• Integration, Migration, and Expansion Services

  Move existing physical & virtual workloads easily, or determine technical requirements to support increased workloads while maximizing performance. Includes tuning, validation, and documenting ongoing run processes. Leverage migration assessment planning documents to perform necessary migrations.
