Overview
Four independent dual-socket servers share one BigTwin chassis, its power and its cooling in the SYS-621BT-HNTR. Each node takes 4th or 5th Gen Xeon Scalable processors, including Xeon CPU Max parts with on-package high-bandwidth memory, plus its own memory bank and AIOM networking. HPC clusters, hyperconverged compute-plus-storage and dense virtualisation are where it lands — anywhere rack space and per-node cost matter more than GPU slots, which this model does not offer. Every unit we quote is new, sourced to order from our partners in China and brought together at the Shenzhen warehouse, where each node is checked against the configuration and its serials are logged. 1-yr hardwaresys RTB + vendor’s own warranty is the cover. Air cooling supports only the lower processor bins on this model; the top parts need the liquid-cooled build. Tell us which processors you want and whether your room has a coolant loop, then request a quote.

Common problems when buying rack servers
"In stock" that isn't
We quote real availability — In Shenzhen — ready, or build-to-order with a date — never a stock status we can't hold.
Grey-market boxes with no history
Every unit is QC-tested with a documented report; you see the checks before it ships.
Refurb that's really e-waste
Grade A refurbished only, same one-year warranty as new — or we tell you to buy new instead.
