Overview
The BigTwin SYS-221BT-HNTR packs four hot-pluggable dual-Xeon nodes into a shared 2U enclosure, maximizing compute density per rack while keeping each node independently serviceable. Nexus Compute configures and validates the full enclosure to your virtualization or hyperconverged design, sourced through authorized Supermicro channels with manufacturer warranty.
Who This Solution Is For
Business Benefits
Four nodes per 2U
Shared power and cooling deliver dense compute that lowers rack, power, and cooling cost per node.
Independent serviceability
Each node hot-plugs from the rear, so one server can be serviced without disturbing the other three.
Efficient shared power
Shared Titanium-level PSUs improve power efficiency versus four discrete 1U servers.
Typical Business Use Cases
Hyperconverged infrastructure clusters
High-density server virtualization
Virtual desktop infrastructure at scale
Private cloud compute pools
Industry Applications
Technical Overview
The X13 BigTwin places four independent nodes in a 2U chassis, each with dual Socket E (LGA-4677) Xeon CPUs, 16 DDR5 DIMM slots, and six hot-swap NVMe/SAS bays. A shared cooling and 3000W Titanium redundant power design maximizes density and efficiency across the enclosure.

Frequently Asked Questions
Can nodes be configured differently?
Nodes in a BigTwin share a chassis but each is an independent server. We typically configure them identically for cluster uniformity, and can advise where mixed builds make sense.
Why choose BigTwin over four 1U servers?
BigTwin delivers the same four-node compute in 2U with shared, more efficient power and cooling, reducing rack space and operating cost while keeping each node serviceable.
Is it suited to hyperconverged software?
Yes. With per-node NVMe and high-speed networking it is a strong building block for VMware vSAN, Nutanix, and similar HCI stacks. We validate the configuration to your platform.
