Supermicro Node Servers

Supermicro node servers are comporised of multiple nodes in one server, usually 2U in size. This means the nodes share a centralised power supply, cooling infrastructure and ofen storage, depending on model.

At ITinStock, we stock a comprehensive range of refurbished Supermicro node servers, including Supermicro BigTwin, FatTwin, TwinPro, GrandTwin, and MicroCloud systems. Browse our selection or contact us for help finding the right Supermicro node server for your business.

The Benefits of Supermicro Node Servers

Supermicro’s Twin family of node servers (the BigTwin, FatTwin, TwinPro, and MicroCloud) is built around one core principle, which is to deliver maximum compute density whilst minimising rack space, power consumption, and cost. These systems are specifically built for organisations running dense virtualisation, private and hybrid cloud infrastructure, high-performance computing (HPC), big data analytics, AI inferencing, and enterprise-grade workloads.

Some models, such as the MicroCloud, can provide 3x more node density than standard 1U rackmount servers, packing up to 10 CPU nodes into one 3U chassis. The BigTwin can house up to four hot-swappable, dual-socket nodes in just 2U. That can result in some hefty space saved, which is useful for constrained data centre environments. Added to Supermicro node servers’ building block structure, in which you can slot in and replace CPUs, memory (RAM) and network cards, these servers provide a flexible system that can scale with your business.

Why Refurbished Supermicro Node Servers from ITinStock?

We stock a wide range of refurbished Supermicro node servers, chassis, and modules at ITinStock, and are happy to discuss bespoke configurations with additional or alternative components to match your exact requirements. Every server undergoes rigorous testing to ensure it operates reliably before it leaves us. We work with our couriers to arrange fast delivery to the UK and worldwide. Our expert support team are on hand to assist with any requirements, from pre-purchase advice through to post-delivery support.

Complement Your Setup

Maximise your Supermicro node server infrastructure with these complementary IT components:

  • Network Cards (PCI Card) Expand connectivity across your Supermicro node chassis with additional network cards. The BigTwin and FatTwin support OCP 3.0 SFF AIOM add-in cards for flexible up to 100G networking options.
  • SSDs We provide a wide range of NVMe, SAS, and SATA SSDs compatible with Supermicro node servers, covering everything from all-flash performance storage to high-capacity hybrid storage.
  • Memory (RAM) We stock compatible DDR4 ECC RDIMM and LRDIMM modules to maximise the memory capacity of your Supermicro node servers. Why not take a look to fit your large-scale virtualisations, databases and HPC workloads?

Frequently Asked Questions

Which Supermicro node server models does ITinStock stock?
We stock refurbished Supermicro multi-node servers across the Twin family product lines. This includes BigTwin systems (2U, 2-node and 4-node configurations) such as the SYS-220BT-HNTR and SYS-221BT-DNTR, FatTwin systems (4U, 4-node and 8-node) such as the SYS-F629P3-RC1B, as well as MicroCloud and TwinPro models. Stock levels vary, so please contact our team for current availability or to discuss a specific configuration. We can also source models to order where required.

What is the difference between the Supermicro BigTwin, FatTwin, TwinPro, and MicroCloud?
Each product line within the Supermicro Twin family is optimised for different workload requirements and density targets. The TwinPro is the entry-level multi-node system, supporting up to four dual-socket nodes in 2U with up to 4TB DDR4 memory per node, which is ideal for cloud computing, virtualisation, and general data centre workloads. The BigTwin is the performance flagship, also in 2U but supporting up to four nodes with up to 6TB of memory per node, the most powerful Intel Xeon Scalable processors, and all-flash NVMe or hybrid NVMe/SAS storage suited for HPC, hyperconverged infrastructure, and big data analytics. The FatTwin scales to a 4U form factor with up to eight nodes, offering the highest compute density for large-scale cloud deployments. The MicroCloud is a 3U system offering up to 10 physically separated single-socket nodes, making it an economical choice for web hosting, dedicated hosting, and lightweight workloads requiring per-node physical isolation.

Do Supermicro node servers require shared infrastructure to operate, or can individual nodes run independently?
Each node in a Supermicro Twin family system is logically independent; it runs its own operating system, has its own CPUs, memory, and storage, and can be managed separately. However, nodes do rely on the shared chassis for power delivery and cooling. This means the chassis and its power supply units (PSUs) must be installed and operational for any node to function. Unlike Supermicro’s SuperBlade platform, Twin family nodes do not require separate connection blades or management modules; the architecture is simpler, with nodes connecting directly into the chassis midplane. If you are building out a new Supermicro node deployment or expanding an existing one, our team can advise on compatible chassis, PSU requirements, and node compatibility.

How do refurbished Supermicro node servers differ from new ones?
Refurbished Supermicro node servers are pre-owned units that have been fully inspected, cleaned, tested, and verified to be in complete working order before resale. At ITinStock, every server undergoes rigorous testing to ensure it meets enterprise operational standards. The primary differences from new units are a lower purchase price and the possibility of minor cosmetic wear on the chassis or node trays. Functionally, our refurbished Supermicro servers deliver the same enterprise-grade performance and hardware capabilities as new equivalents, often at a fraction of the cost. This makes them an excellent choice for businesses looking to build or scale high-density compute infrastructure cost-effectively.

Does ITinStock offer a warranty on refurbished Supermicro node servers?
Yes. All our refurbished Supermicro node servers are thoroughly inspected and tested before dispatch to ensure they are functioning as intended. In the event that a unit develops a fault or arrives damaged through no fault of the customer, we offer a 3-year warranty on all refurbished IT equipment covering repair or replacement (within reason). Please speak with our account managers and customer service team for full warranty terms and conditions.
