BigTwin®: Industry-leading Multi-node Architecture

Supermicro X13 BigTwin® systems provide maximum performance and serviceability in a multi-node architecture, with dual 5th Gen Intel® Xeon® processors per node and a hotswappable tool less design.

Optimized for density (2U4N) or storage (2U2N), BigTwin systems with shared components can be more cost-effective than standard 1U servers, with Supermicro’s Resource Saving Architecture of shared power and cooling reducing TCO and TCE. A range of storage configurations are also available, with up to 24 hot-swap 2.5” NVMe drives in a 2U rackmount chassis.
