Lenovo ThinkSystem SR650a V4: your first step towards in-house AI in 2U

Want to get started with your own artificial intelligence but do not want to build an entire data centre? Lenovo ThinkSystem SR650a V4 gives you the power for large language models in a 2U chassis that fits into any rack. Two NVIDIA RTX PRO 6000 Blackwell cards with 192GB of GPU memory handle models from 7 to 70 billion parameters and support dozens of users simultaneously. Your data stays safely within your company, response times are lightning-fast, and costs remain predictable. Whether you are building an internal AI assistant, a customer chatbot, or automation agents, the SR650a V4 is the perfect starting point. This configuration has been prepared by Alza based on the Lenovo AI Express programme.

  • 2× GPU RTX PRO 6000 Blackwell Server Edition — a total of 192GB GDDR7 ECC memory (96GB per card) for large language model inference, fine-tuning, as well as image and video generation.
  • Lenovo ThinkSystem SR650a V4 platform — 2U GPU server with space for up to 4 double-slot cards; the platform also features the SR650i V4 inference model.
  • 2× Intel Xeon 6530P — 2× 32 cores / 64 threads, 2.3GHz clock speed (up to 4.1GHz turbo), and 144MB cache per processor.
  • 512GB DDR5 ECC Registered (RDIMM) — 6400MT/s, utilising 16 modules of 32GB out of 32 available slots.
  • 2× 3.84TB NVMe SSD U.2 — enterprise-grade drives with PCIe 5.0 interface, complemented by 2× 960GB M.2 NVMe for the operating system.
  • Delivery in as little as 15 days — configuration from the Lenovo AI Express programme; RAM and SSD capacities can be customised on request.

Component details

2× RTX PRO 6000 Blackwell Server Edition
Two RTX PRO 6000 Blackwell Server Edition cards provide 96GB of memory per card, totalling 192GB. This is ideal for running models with tens of billions of parameters, long context windows, and concurrent requests. These passive cards are cooled by the server's powerful fans, with each card featuring a PCIe 5.0 x16 connection and power draw up to 600W. They are perfect for inference, fine-tuning models, generative AI, and visualisation. Want to know more: MIG technology lets you partition each card into isolated instances, allowing one server to support multiple teams or services.
2× Intel Xeon 6530P
Two Granite Rapids generation processors deliver a combined total of 64 cores and 128 threads, with a base clock of 2.3GHz and a turbo frequency of up to 4.1GHz. Featuring eight memory channels per processor, support for DDR5 6400MT/s, and a PCIe 5.0 interface, they supply data to both cards without delay. The processors pre-process data, handle requests, and accelerate non-GPU tasks with built-in AMX, QAT, DSA, IAA, and DLB engines.
512GB DDR5 ECC Registered + 2× 3.84TB NVMe
This system includes 16 modules of 32GB TruDDR5 RDIMM 6400MHz, providing 512GB RAM in total. You can easily add more capacity using the 16 free slots, as the platform supports up to 8TB. Store models and data on 2× 3.84TB U.2 SSDs with NVMe PCIe 5.0 x4 interface (totalling 7.68TB). The operating system runs on a pair of 960GB M.2 NVMe SSDs.
ThinkSystem SR650a V4
The SR650a V4 is engineered to deliver maximum GPU performance within a 2U chassis. The graphics cards are positioned at the front for fresh air intake, while six 24K fans keep them cool even under full load. Two 3200W Titanium power supplies provide redundancy, and the XClarity Controller 3 with a Premier license enables remote management, including KVM and virtual media. TPM 2.0 and Secure Boot complete the security features.

Questions

Frequently asked questions

Who is the Lenovo ThinkSystem SR650a V4 designed for?
For businesses starting out with their own AI: language model inference, internal assistants, chatbots, fine-tuning smaller models or generative applications. It is also suitable for visualisation and image and video processing.
What size language model can I run on the server?
According to the Lenovo AI Express (size S) classification, the system is designed for models with roughly 7 to 70 billion parameters and dozens of concurrent users at speeds of 30 or more tokens per second. Actual performance depends on quantisation, context length and the server application (e.g. vLLM, TensorRT-LLM).
How much GPU memory does the setup offer?
192GB (2×96GB). The memory does not aggregate into a single address space between the cards, but frameworks can distribute the model across both cards.
Do I need a special power supply?
Yes. The 3200W Titanium power supplies require a 230V feed. We recommend connecting them to two separate phases and verifying the capacity of your distribution board.
What is included in the delivery and how quickly will it arrive?
The server comes with power supplies, cables and rails. Thanks to the Lenovo AI Express programme, delivery is possible within 15 days from the distributor order (subject to meeting all requirements, such as the EUC document). The sales department will confirm the exact date.
Can the server be expanded?
Yes. The platform supports up to 8TB RAM (32 slots), 6 free bays for NVMe drives and additional GPUs (up to 2 dual-slot cards, depending on type and power consumption). Please consult us about any upgrades to maintain compatibility and warranty.

Lenovo is the world's largest computer maker, founded in 1984. Its original name was Legend. Later it was renamed to Legend Novo ("New Legend"), abbreviated Lenovo. In 2005 it took over IBM's computer division, which was among the largest computer makers in the world. It is similarly ambitious in the field of mobile phones, where it would like to surpass Apple and Samsung. As far as this goal goes, they acquired Motorola’s mobile division in January 2014 and have been ramping up production since. 

The company also produces tablets, monitors, televisions, and storage solutions. Overall, they are known for delivering quality products at reasonable prices.
