Ingrasys GB2281A
Ingrasys, the data centre arm of Foxconn, builds this as its AMD accelerator node: eight Instinct MI355X modules on a UBB 2.0 universal baseboard connected by Infinity Fabric mesh. The dimensions give away who it is for. At 524.3 mm wide and 93.5 mm high it is an Open Compute 21 inch node at two OpenU, not a 19 inch rack unit, which is how these reach hyperscale buyers rather than enterprise racks. Storage is sixteen E1.S NVMe bays, expansion eight PCIe Gen5 x16 slots, management an AST2600, and cooling is direct liquid to the accelerators with four 80 mm fans in N+1 for everything else. Ingrasys publishes no power figure and no throughput for the node. It does quote 2.3 TB of HBM3E and 64 TB/s of aggregate bandwidth, but for the AMD platform rather than for this product, so those are on the linked platform entry where AMD publishes them.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.

Frequently asked questions
How much does the GB2281A cost?
Ingrasys sells the GB2281A on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 8 Instinct MI355X accelerators separately at the cheapest live rate Flopper tracks, $5.99 per GPU-hour across 1 provider, comes to about $47.92 an hour for the equivalent capacity.

How much power does the GB2281A require?
Ingrasys has not published a power figure for the GB2281A, and Flopper does not derive one from the accelerator count because the rest of the system draws power too.
How many GPUs are in the GB2281A?
8. The GB2281A carries 8 AMD Instinct MI355X OAM accelerators in a rack form factor, and every throughput figure on this page is the total across them. Instinct MI355X specifications →
