This week, Gigabyte announced the availability of a new product line of multi-node servers. The company has made 2U 4-node servers for many years, but it is now going into the market of even higher-density designs based on both AMD EPYC and Intel Xeon. It has also shown off liquid-cooled blade server designs.
Gigabyte B363 Multi-Node Servers
The Gigabyte B363 was at Computex, but these are officially coming to market. The Gigabyte B363 has both AMD EPYC 4005 / Ryzen 9000 series and Intel Xeon 6300 series versions that fit 10x single-socket nodes in 3U. The initial versions have dual 1GbE NICs, but let us just say I think there is a good reason for Gigabyte to offer faster onboard networking as well.
In the rear, Gigabyte has four power supplies for redundant power, and also has shared chassis management NICs. The feature that may be easily overlooked here are the OCP NIC 3.0 slots. There are three slots that can be used with multi-host NICs. Instead of consolidating networking and cabling using a chassis switch, one can use multi-host NICs which actually reduces complexity by removing a layer of switching.
The Gigabyte B343-C40 is the AMD version while the B343-X40 is the Intel version. While the specs say the systems support three OCP NIC 3.0 multi-host adapters, it appears as though the systems have five slots.
For dedicated hosting companies, this type of deployment model is great because it allows for shared power supplies, chassis, and cooling thereby lowering the total CapEx cost to get nodes online.
Gigabyte B683 6U Blade Servers at Computex 2025
At Computex 2025, there were a few early Gigabyte B683 blade servers. These are 6U 10-node designs.
Making these notable is not just having multi-node systems. The company is also working on liquid cooled designs. If you look at the prototype nodes below, you can see not just CPU and memory liquid cooling, but the rear nozzles are for an internal manifold which means each node does not need external warm and cool liquid cooling connections to a rack manifold.
That may not seem like a big deal to some, but 20x 500W TDP CPUs in a 6U chassis would be around 10kW, making the total system power in-line and sometimes denser than modern 8-GPU air-cooled AI servers.
Final Words
We cannot go into more details around unreleased products, but Gigabyte has more versions of these multi-node systems in the works. Given the popularity of the multi-node form factors in the entry Intel Xeon and AMD EPYC markets, those make a lot of sense. Also, liquid cooling blade servers is going to become a more mainstream option as AI data centers transition to liquid cooling in 2026.
Stay tuned to STH for more on these soon.
