Introducing: the 21” OAM (OCP Acceleration Module) reference system

On September 26 at the OCP Regional Summit in Amsterdam, Inspur rolled out an all new OCP Acceleration Module (OAM) Reference System, which delivers a multi-OAM Universal Baseboard (UBB) supporting various interconnect topologies simplifying the interconnection communication links among ASIC or GPU based modules.

Let’s back up to March earlier this year, when OCP first announced the OCP Accelerator Mezzanine Module design specification at the OCP Global Summit. It defines the form factor and common specifications for a compute accelerator module, a compliant base board design enabling interoperability across multiple ASIC or GPU based mezzanine modules, and a baseboard design plan. The mezzanine module form factor facilitates scalability across accelerators by simplifying the system solution when interconnecting communication links among modules in comparison with a PCIe Add-in card form factor.

The Universal Baseboard (UBB) team was then formed, led by Inspur, Hyve, ZT Systems, and Inventec, and completed the UBB specifications that allow protocol agnostic interconnects between accelerators to scale up. Inspur proceeded to develop the OCP Acceleration Module (OAM) Reference System, in response to the increasing demands from AI applications and the need for interoperability across multiple ASIC or GPU based modules.

Fast forward to now: Inspur’s OAM system is a 21-inch Open Rack V2 OAM OCP compliant solution providing inter-module communication for scale-up and input/output bandwidth for scale-out. These features support disparate network architectures through OAM direct connect, delivering increased efficiency, flexibility and manageability.

Inspur OAM system has the capability to build 16, 32, 64, and 128 OAM clusters and has the flexible architecture to support multi-host infrastructures. Inspur can also deliver 19-inch OAM systems upon customer demand.

As a longtime sponsor and advocate for OCP and standardized server systems, Inspur continues to take major next steps to broaden the global OCP ecosystem with this OAM solution.
