HPE HDR InfiniBand switches and adapters
200Gb/s InfiniBand switching and adapters for HPC and AI clusters.
- Who it's for
- Organisations building a multi-server GPU cluster
- Scale
- Level 5
Routers rather than switches: used where AI traffic has to travel between datacentres or between sites, instead of staying inside one room. Built on Juniper's custom silicon following HPE's acquisition of Juniper.
No payment is taken online. Every request is an enquiry answered by an engineer.
Where does this sit?
Rack-Scale & Supercomputing. Integrated racks where compute, interconnect, storage, power and liquid cooling are engineered as a single system. Typically bought by a datacentre operator, a national facility or a large ai platform. Datacentre with liquid cooling and high-density power.
