For details about these preset modes, and all other performance and power efficiency UEFI settings offered in the SR675 V3, see the paper "Tuning UEFI Settings for Performance and Energy Efficiency on AMD Processor-Based ThinkSystem Servers", available from https://lenovopress.lenovo.com/lp1267.

The SR675 V3 uses Lenovo TruDDR5 memory operating at up to 6000 MHz with 5th Gen AMD EPYC processors, and up to 4800 MHz with 4th Gen AMD EPYC processors. The server supports up to 24 DIMMs with 2 processors. The processors have 12 memory channels and support 1 DIMM per channel. The server supports up to 3TB of memory using 24x 128GB DIMMs and two processors.

Lenovo TruDDR5 memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned to maximize performance and reliability. From a service and support standpoint, Lenovo TruDDR5 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The following table lists the memory options supported in the SR675 V3 with 5th Gen AMD EPYC processors.

The following table lists the memory options supported in the SR675 V3 with 4th Gen AMD EPYC processors.

9x4 RDIMMs (also known as Optimized or EC4 RDIMMs) are a lower-cost DDR5 memory option supported in ThinkSystem V3 servers. 9x4 DIMMs offer the same performance as standard RDIMMs (known as 10x4 or EC8 modules), however they support lower fault-tolerance characteristics. Standard RDIMMs and 3DS RDIMMs support two 40-bit subchannels (that is, a total of 80 bits), whereas 9x4 RDIMMs support two 36-bit subchannels (a total of 72 bits). The extra bits in the subchannels allow standard RDIMMs and 3DS RDIMMs to support Single Device Data Correction (SDDC), however 9x4 RDIMMs do not support SDDC. Note, however, that all DDR5 DIMMs, including 9x4 RDIMMs, support Bounded Fault correction, which enables the server to correct most common types of DRAM failures.

Figure 13. Locations of slots

All GPU and I/O slots are enabled using plug-in or cabled riser cards. Ordering information is shown in the following table.

1. The direct x16 riser (feature BR7Q) has four x16 connections (64 lanes total, implemented using eight x8 cables) for connecting to the system processors. This provides a direct 1:1 connection to all four GPUs.
2. The switched riser with GPUDirect RDMA (feature BR7S) it allows the implementation of NVIDIA GPUDirect RDMA. Designed specifically for the needs of GPU acceleration, GPUDirect RDMA provides direct communication between NVIDIA GPUs in remote systems. This eliminates the system CPUs and the required buffer copies of data via the system memory, resulting in 10X better performance. The riser provides a x16 connection directly to I/O slots.
3. The direct x8 riser (feature BR7R) has four x8 connections (32 lanes total, implemented using four x8 cables) for connecting to the system processors. This provides a direct 1:1 connection to all eight GPUs.
4. The NVIDIA SXM5 CX7 Mezz Carrier Board (feature BR7P) provides a networking interface including four NVIDIA ConnectX-7 VPI network controllers for the Nvidia SXM5 baseboard. This provides an OSFP connection to the Front IO riser. The riser allows GPU direct connections for the network only.

5. The SXM5 PCIe Switch Riser (feature BR9D) supports 4-Way SXM5 4-GPU baseboard. The switched riser allows the implementation of NVIDIA GPU Direct. This eliminates the system CPUs and the required buffer copies of data via the system memory, resulting in better performance. BR9D provides two x16 connection to the Front IO riser that are NVIDIA GPU Direct.

   In a dual socket configuration, the riser provides four x16 connections to the CPUs (a 1:1 connection for GPU to CPU), but no direct rear I/O connections. No additional GPU Direct connections.

   Use of the GPU risers is as follows:

   • The 8-DW GPU model uses 2 switched GPU risers or 2 direct GPU risers.
     • The switched GPU riser configuration provides x16 connection for eight GPUs using a 1:2 subscription.
     • The direct GPU riser configuration provides x8 connection for eight GPUs using a 1:1 subscription.
   • The 4-DW GPU model can use either
     • A direct x16 riser (1:1) or a switched x16 riser (1:2) to provide connections for four GPUs. Each GPU gets a x16 connection. The choice of GPU riser is based on what other I/O risers are used in the configuration.
   • The SXM GPU model can use either:
     • A PCIe switch riser or a ConnectX-7 4-chip VPI PCIe Gen5 Mezz Controller to provide connection to the NVIDIA HGX H100 80GB 700W 4-GPU Board. The HGX 4-GPU board gets four x16 connection. The choice of GPU riser is based on the need for NVIDIA GPU Direct and the I/O Front network connections.

   The slots at the rear of the server are 2-slot risers. The mechanical cage has a third slot at the top which does not support an adapter, but is instead of use either for a serial port or for a RAID adapter supercap. Adapter slots are as follows:

   • Riser BR7N has one PCIe 5.0 x16 slots
   • Riser BR7L has two PCIe 5.0 x16 slots. It supports PCIe 5.0 on the bottom slot (slot 15 and slot 20). It supports PCIe 5.0 on top slot depending on configuration*
   • Riser BR7M has one PCIe 5.0 x16 slot (bottom slot) and one PCIe 4.0 x8 slot (top slot - slot 21)

   *Slot 21 exhibits a maximum compatibility with Gen4 in select configurations: 3, 4, 8, 12, 18, 22, 23, 26, 28, and 31

   The following figure shows the rear riser.

   
   Figure 14. Rear riser

The SR675 V3 supports the following graphics processing units (GPUs), depending on the front shuttle selected. All GPUs installed must be identical. 

*CN, Hong Kong and Macao only

Configuration rules:

• Some NVIDIA A Series GPUs are available as two feature codes, one with a CEC chip and one without a CEC chip (ones without the CEC chip have "w/o CEC" in the name). The CEC is a secondary Hardware Root of Trust (RoT) module that provides an additional layer of security, which can be used by customers who have high regulatory requirements or high security standards. NVIDIA uses a multi-layered security model and hence the protection offered by the primary Root of Trust embedded in the GPU is expected to be sufficient for most customers. The CEC defeatured products still offer Secure Boot, Secure Firmware Update, Firmware Rollback Protection, and In-Band Firmware Update Disable. Specifically, without the CEC chip, the GPU does not support Key Revocation or Firmware Attestation. CEC and non-CEC GPUs of the same type of GPU can be mixed in field upgrades.

• The table includes a Controlled GPU column. If a GPU is listed as Controlled, that means the GPU is not offered in certain markets, as determined by the US Government. If a GPU is listed as No, that means the GPU is not controlled and is available in all markets.
• The double-wide GPUs also support the installation of an NVLink bridge between adjacent pairs of GPUs. H200 NVL GPUs use either one NVLink 2-way bridge per pair or one NVLink 4-way bridge per set of 4 GPUs. H100 GPUs use three NVLink bridges per pair. A40 and A30 GPUs support one NVLink bridge per pair. Ordering information in the following table.
• The H200 (C3V2, C3V3) GPUs are available with the 5th Gen AMD EPYC processors (Turin) server models only.

For information about these GPUs, see the ThinkSystem GPU Summary, available at:
https://lenovopress.com/lp0768-thinksystem-thinkagile-gpu-summary

When adding a double-wide GPU as a field upgrade, you will need an additional GPU auxiliary power cable as listed in the following table.

The server has a dedicated OCP 3.0 SFF slot with either a PCIe 4.0 x8 or x16 host interface, depending on the server configuration as described in the Configurations section. See Figure 3 for the location of the OCP slot.

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 SR675 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 SR675 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.

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

   VTT AI: The NetApp AIPod with Lenovo for NVIDIA OVX
   
   

   AI, for some organizations, is out of reach, due to cost, integration complexity, and time to deployment. Previously, organizations relied on frequently retraining their LLMs with the latest data, a costly and time-consuming process. The NetApp AIPod with Lenovo for NVIDIA OVX combines NVIDIA-Certified OVX Lenovo ThinkSystem SR675 V3 servers with validated NetApp storage to create a converged infrastructure specifically designed for AI workloads. Using this solution, customers will be able to conduct AI RAG and inferencing operations for use cases like chatbots, knowledge management, and object recognition.
   
   Topics covered in this VTT session include:
   •  Where Lenovo fits in the solution
   •  NetApp AIPod with Lenovo for NVIDIA OVX Solution Overview
   •  Challenges/pain points that this solution solves for enterprises deploying AI
   •  Solution value/benefits of the combined NetApp, Lenovo, and NVIDIA OVX-Certified Solution
