Components
The main hardware components of Lenovo Hybrid AI platforms are Compute nodes and the Networking infrastructure. As an integrated solution they can come together in either a Lenovo EveryScale Rack (Machine Type 1410) or Lenovo EveryScale Client Site Integration Kit (Machine Type 7X74). Topics in this section:
AI Compute Node SR675 V3 Service Nodes SR635 V3 Cisco Networking Lenovo EveryScale Solution AI Compute Node SR675 V3 The AI Compute Node leverages the Lenovo ThinkSystem SR675 V3 GPU-rich server.
Figure 4. Lenovo ThinkSystem SR675 V3 in 8DW PCIe Setup The SR675 V3 is a 2-socket 5th Gen AMD EPYC 9005 server supporting up to 8 PCIe DW GPUs with up to 5 network adapters in a 3U rack server chassis. This makes it the ideal choice for NVIDIA’s 2-8-5 configuration requirement.

Figure 5. Lenovo ThinkSystem SR675 V3 in 8DW PCIe Setup The SR675 V3 is configured as the 285 AI compute node as shown in the figure below.
Figure 6. AI Compute Node Block Diagram
Lenovo Hybrid AI 285 with Cisco Networking
4
The AI Compute node is configured with two AMD EPYC 9535 64 Core 2.4 GHz processors with an all-core boost frequency of 3.5GHz. Besides providing consistently more than 2GHz frequency this ensures that with 7 Multi Instance GPUs (MIG) on 8 physical GPUs there are 2 Cores available per MIG plus a few additional Cores for Operating System and other operations.
With 12 memory channels per processor socket the AMD based server provides superior memory bandwidth versus competing Intel-based platforms ensuring highest performance. Leveraging 64GB 6400MHz Memory DIMMs for a total of 1.5TB of main memory providing 192GB memory per GPU or a minimum of 1.5X the H200 NVL GPU memory.
The GPUs are connected to the CPUs via two PCIe Gen5 switches, each supporting up to four GPUs. With the NVIDIA H200 NVL PCIe GPU , the four GPUs are additionally interconnected through an NVLink bridge, creating a unified memory space. In an entry configuration with two GPUs per PCIe switch, the ThinkSystem SR675 V3 uniquely supports connecting all four GPUs with an NVLink bridge for maximized shared memory, thereby accommodating larger inference models, rather than limiting the bridge to two GPUs. With the RTX PRO 6000 Blackwell Server Edition, no NVLink bridge is applicable, same applies to configurations with the L40S.
Key difference from the base platform : For the 2-8-5 architecture with Cisco networking the AI Compute node leverages NVIDIA CX-7s for both the East-West and the North South communication. This is a key difference in the AI compute node configuration compared to the base 285 platform with NVIDIA networking. This is done primarily because, as of now, Cisco switching does not work with NVIDIA’s dynamic load balancing technology within Spectrum-X, leveraged by their Bluefield-3 cards. This will change in future updates of this document as that technology is onboarded by Cisco and Lenovo brings in the new Silicon One 800GbE switch.
The Ethernet adapters for the Compute (East-West) Network are directly connected to the GPUs via PCIe switches minimizing latency and enabling NVIDIA GPUDirect and GPUDirect Storage operation. For pure Inference workload they are optional, but for training and fine-tuning operation they should provide at least 200Gb/s per GPU.
Finally, the system is completed by local storage with two 960GB Read Intensive M.2 in RAID1 configuration for the operating system and four 3.84TB Read Intensive E3.S drives for local application data.
GPU selection
The Hybrid AI 285 platform is designed to handle any of NVIDIA’s DW PCIe form factor GPUs including the new RTX PRO 6000 Blackwell Server Edition, the H200 NVL, L40S and the H100 NVL.
NVIDIA H200 NVL
The NVIDIA H200 NVL is a powerful GPU designed to accelerate both generative AI and highperformance computing (HPC) workloads. It boasts a massive 141GB of HBM3e memory, which is nearly double the capacity of its predecessor, the H100. This increased memory, coupled with a 4.8 terabytes per second (TB/s) memory bandwidth, enables the H200 NVL to handle larger and more complex AI models, like large language models (LLMs), with significantly improved performance. In addition, the H200 NVL is built with energy efficiency in mind, offering increased performance within a similar power profile as the H100, making it a cost-effective and environmentally conscious choice for businesses and researchers.
NVIDIA provides a 5-year license to NVIDIA AI Enterprise free-of-charge bundled with NVIDIA H200 NVL GPUs.
NVIDIA RTX PRO 6000 Blackwell Server Edition
Built on the groundbreaking NVIDIA Blackwell architecture, the NVIDIA RTX PROTM 6000 Blackwell Server Edition delivers a powerful combination of AI and visual computing capabilities to accelerate enterprise data center workloads. Equipped with 96GB of ultra- fast GDDR7 memory, the NVIDIA RTX PRO 6000 Blackwell provides unparalleled performance and flexibility to accelerate a broad range of use cases- from agentic AI, physical AI, and scientific computing to rendering, 3D graphics, and video.

Service Nodes SR635 V3
When deploying the Hybrid AI 285 platform in a sizing beyond beyond 2 AI compute nodes additional service nodes are recommended to manage the overall AI cluster environment.
Key difference from the base platform: Because the architecture for this platform does not yet leverage Spectrum-X, there is no need for Bluefields within the service nodes. For this reason the customer can leverage the lower cost SR635 V3 instead of the SR655 V3.
Two Management Nodes provide a high-availability for the System Management and Monitoring provided through NVIDIA Base Command Manager (BMC) as described further in the AI Software Stack chapter.

Lenovo EveryScale Solution
The Server and Networking components and Operating System can come together as a Lenovo EveryScale Solution. It is a framework for designing, manufacturing, integrating and delivering data center solutions, with a focus on High Performance Computing (HPC), Technical Computing, and Artificial Intelligence (AI) environments.
Lenovo EveryScale provides Best Recipe guides to warrant interoperability of hardware, software and firmware among a variety of Lenovo and third-party components.
Addressing specific needs in the data center, while also optimizing the solution design for application performance, requires a significant level of effort and expertise. Customers need to choose the right hardware and software components, solve interoperability challenges across multiple vendors, and determine optimal firmware levels across the entire solution to ensure operational excellence, maximize performance, and drive best total cost of ownership.
Lenovo EveryScale reduces this burden on the customer by pre-testing and validating a large selection of Lenovo and third-party components, to create a “Best Recipe” of components and firmware levels that work seamlessly together as a solution. From this testing, customers can be confident that such a best practice solution will run optimally for their workloads, tailored to the client’s needs.
In addition to interoperability testing, Lenovo EveryScale hardware is pre-integrated, pre-cabled, pre-loaded with the best recipe and optionally an OS-image and tested at the rack level in manufacturing, to ensure a reliable delivery and minimize installation time in the customer data center.
Scalability
A fundamental principle of the solution design philosophy is its ability to support any scale necessary to achieve a particular objective.
In a typical Enterprise AI deployment initially the AI environment is being used with a single use case, like for example an Enterprise RAG pipeline which can connect a Large Language Model (LLM) to Enterprise data for actionable insights grounded in relevant data.
In its simplest form, leveraging the NVIDIA Blueprint for Enterprise RAG pipeline involves three NVIDIA Inference Microservices: a Retriever, a Reranker, and the actual LLM. This setup requires a minimum of three GPUs.
Lenovo Hybrid AI 285 with Cisco Networking
11
Figure 13. NVIDIA Blueprint Architecture Diagram
As the deployment of AI within the company continues to grow, the AI environment will be adapted to incorporate additional use cases, including Assistants or AI Agents. Additionally, it has the capacity to scale to support an increasing number of Microservices. Ultimately, most companies will maintain multiple AI environments operating simultaneously with their AI Agents working in unison.
The Lenovo Hybrid AI 285 with Cisco Networking platform has been designed to meet the customer where they are at with their AI application and then seamlessly scale with them through their AI integration. This is achieved through the introduction of the following:
Entry and AI Starter Kit Deployments Scalable Unit Deployment Custom Deployment
A visual representation of the sizing and scaling of the platform is shown in the figure below.
Lenovo Hybrid AI 285 with Cisco Networking

Figure 14. Lenovo Hybrid AI 285 with Cisco Networking Scaling
Entry and AI Starter Kit Deployments
Entry deployment sizings are for customers that want to deploy their initial AI factory with 4-16x GPUs. Entry deployments have one or two SR675 V3 servers, with 8x GPUs per server (AI Compute Nodes). With two servers configured, the two servers are connected directly via the installed NVIDIA ConnectX-7 or NVIDIA BlueField adapters.
If additional networking is required or additional storage is required, then use the AI Starter Kit deployment, which supports up to 4x servers and up to 32x GPUs. The AI Starter Kit uses NVIDIA networking switches and ThinkSystem DM or DG external storage.
The following sections describe these deployments:
Entry sizing AI Starter Kits
Entry sizing
Entry sizing starts with a single AI Compute node, equipped with four GPUs. Such entry deployments are ideal for development, application trials, or small-scale use, reducing hardware costs, control plane overhead, and networking complexity. With all components on one node, management and maintenance are simplified.
Entry sizing can also support two AI Compute nodes, directly connected together and without the need for external networking switches, to scale up to 16 GPUs if fully populated (2 nodes, 8x GPUs per node). The two nodes connect to the rest of your data center using existing networking in your data center.

Compute Network adapters per server
4-8x GPUs 1x SR675 V3 Minimum ratio of 1 CX7 per 2 GPUs
8-16x GPUs 2x SR675 V3 Minimum ratio of 1 CX7 per 2 GPUs
AI Starter Kits
For customers who want storage and/or networking in the Entry sizing, Lenovo and Cisco worked to develop AI Starter Kits with Cisco networking which allows up to 32 GPUs across 4 nodes, slightly more than the base 285 starter kit sizing which allows for up to only 24 GPUs. This sizing is for customers who do not plan to scale above 32 GPUs in the near future but still need an end-to-end solution for compute and storage.
Networking between the nodes is implemented using the Cisco 9332D-GX2B 200GbE switches and NVIDIA ConnectX-7 dual-port 200Gb adapters in each server.
Storage is implemented using either ThinkSystem DM or ThinkSystem DG Storage Arrays. Features include:
Easy to deploy and scale for performance or capacity Unified file, object, and block eliminates AI data silos High performance NVMe flash and GPUdirect enable faster time to insights Confidently use production data to fine tune models with advanced data management features

Scalable Unit Deployment
For configurations beyond two nodes, it is advisable to deploy a full Scalable Unit along with the necessary network and service infrastructure, providing a foundation for further growth in enterprise use cases.
The fist SU consists of up to four AI Compute nodes, minimum five service nodes, and networking switches. When additional AI Compute Nodes are required, additional SUs of four AI Compute Nodes can be added.
Figure 17. Scalable Unit Deployment
Networking is implemented using Cisco 93108TC-FX3P switches and CX-7 adapters in the AI Compute Nodes. The combination of these two pieces allows the user to take advantage of NVIDIA’s Spectrum-X networking, an Ethernet platform that delivers the highest performance for AI, machine learning, and natural language processing.
The networking decision depends on whether the platform is designed to support up to three Scalable Units in total, and whether it will handle exclusively inference workloads or also encompass future fine-tuning and retraining activities. Subsequently, the solution can be expanded seamlessly without downtime by incorporating additional Scalable Units, ultimately reaching a total of three as needed.
Custom Deployment
For high-end scenarios requiring more than eight scalable units, the network can be custom designed to any required size. Lenovo will develop a fully bespoke solution tailored to match the workflow and workload requirements in that case.
