Kaytus KR1280 V3
Two Intel Xeon 6 with 8,000 MT/s MCR memory and ten NVMe bays in a single rack unit — compute density without the compromises.
From £1,819 ex. VAT — final price depends on configuration. Built to order, typical 4-week lead time confirmed on your quotation.
Maximum compute, minimum rack space.
Every rack unit you save is power, cooling and colocation money back in your budget. The KR1280 V3 packs two Intel Xeon 6 processors — up to 288 efficiency cores per node — into 1U, with MCR memory running at up to 8,000 MT/s where standard 2U platforms sit at 6,400. Ten hot-swap 2.5" bays take NVMe, SAS or SATA, power is redundant, and cooling is air or cold plate. For dense private clouds, HPC nodes and CDN edges, it simply does more per U than a 2U ever will.

Who is KAYTUS?
KAYTUS is a global provider of IT infrastructure — open, energy-efficient server platforms for cloud, AI and edge, backed by three factories, two R&D centres and operations across more than 70 countries. The name comes from K2, the mountain climbers rate the hardest on earth — a fair summary of the engineering standard these machines are built to. Bytehaus is KAYTUS's UK Gold Partner: every server is configured, quoted and supported locally.

MCR (Multiplexer Combined Ranks) DIMMs deliver up to 8,000 MT/s — roughly 25% more memory bandwidth than standard DDR5-6400. In dense nodes where every core competes for bandwidth, that's the difference between cores that scale and cores that stall.
No — hot-swap drives, redundant PSUs and tool-less rails are all standard. The 1U form factor trades PCIe expansion, not serviceability: GPU-heavy builds usually step up to the KR2280 V3 instead.
Every KAYTUS server is built to order against your exact configuration. Typical lead time is four weeks from order, confirmed on your formal quotation — and we'll flag anything that affects it before you commit.
Every server includes a manufacturer-backed 3-year warranty and UK-based technical support from Bytehaus, covering pre-sales sizing through to post-deployment. Extended cover is available on request.
