Lenovo Infrastructure Solutions Group has just announced the new ThinkSystem V2 family of two-socket servers, based on the third-generation Intel Xeon Scalable processors. Learn about the eight new servers.


Lenovo Infrastructure Solutions Group announces the next-generation Lenovo ThinkSystem servers showcasing a unique balance of performance, security and efficiency – all built on 3rd Gen Intel® Xeon® Scalable processors and PCIe Gen4.

As companies of all sizes continue to work on solving real-world challenges – they require powerful infrastructure solutions to help them gain faster insights and remain competitive. With this new generation of ThinkSystem solutions, Lenovo introduces innovations for real-world workloads including high performance computing (HPC), artificial intelligence (AI), modeling and simulation, cloud, virtual desktop infrastructure (VDI) and advanced analytics.

The new servers can be divided into two groups based on customer workload:

  • Mainstream servers in rack, tower and blade form factor offering enhanced performance, reliability, flexibility and security:
    • ThinkSystem SR650 V2 - 2U rack server
    • ThinkSystem SR630 V2 - 1U rack server
    • ThinkSystem ST650 V2 - tower server
    • ThinkSystem SN550 V2 - blade server
  • HPC/AI performance-optimized servers that provide massive computing power in minimal floor space with reduced energy consumption:
    • ThinkSystem SR670 V2 - 3U GPU-optimized air-cooled server
    • ThinkSystem SD650 V2 - water-cooled CPU-optimized server
    • ThinkSystem SD650-N V2 - water-cooled GPU-optimized server
    • ThinkSystem SD630 V2 - air-cooled 2U4N dense compute nodes

ThinkSystem SR670 V2

This highly versatile acceleration platform is designed for HPC and AI training workloads, supporting the NVIDIA Ampere datacenter GPU portfolio. With six base configurations that support four high-performance SXM4 GPUs or up to eight PCIe double-wide GPUs, the SR670 V2 allows customers the flexibility to GPUs and supporting I/O that they need. SXM4 configurations feature the Lenovo Neptune liquid-to-air heat exchanger that provides the benefits of liquid cooling without the adding plumbing.

ThinkSystem SD650 V2

Based on industry-acclaimed fourth generation, Lenovo Neptune cooling technology, utilizes a highly reliable copper loop and cold plate architecture removing up to 90% of the systems heat (1). The ThinkSystem SD650 V2 is built to tackle compute-intensive workloads such as HPC, AI, cloud, grid and advanced analytics.

ThinkSystem SD650-N V2

Expanding the Lenovo Neptune platform, direct water-cooling technology for GPUs, this server combines two 3rd Gen Intel Xeon Scalable processors with four NVIDIA A100 SXM4 GPUs to deliver maximum performance in a dense 1U package. A rack of Lenovo ThinkSystem SD650-N V2 delivers enough compute performance to place in the top 300 of the TOP500 list of supercomputers (2)

ThinkSystem SD630 V2

This ultra-dense, ultra-agile server handles twice the workloads per server rack unit of rack space vs. traditional 1U servers. By leveraging Lenovo Neptune Thermal Transfer Modules, the SD630 V2 supports processors up to 250W, driving 1.5 times the performance of the previous generation in the same rack space (3).

ThinkSystem security

With the ThinkSystem V2 servers, Lenovo is now enhancing security aspects of the servers, both in the manfacturing supply chain and in the delivery of firmware updates.

Intel Transparent Supply Chain

With Intel ThinkSystem servers and Intel Transparent Supply Chain, you can add a layer of protection in your data center and have peace of mind that the server hardware you bring into it is safe authentic and with documented, testable, and provable origin.

Lenovo has one of the world’s best supply chains, as ranked by Gartner Group, backed by extensive and mature supply chain security programs that exceed industry norms and US Government standards. Now we are the first Tier 1 manufacturer to offer Intel® Transparent Supply Chain in partnership with Intel, offering you an unprecedented degree of supply chain transparency and assurance.

For more information on this offering, see the paper Introduction to Intel Transparent Supply Chain on Lenovo ThinkSystem Servers, available from

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 systems 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 systems 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).

Tip: If Secure Boot is not enabled in the factory, it can be enabled later by the customer. However once Secure Boot is enabled, it cannot be disabled.
