'''Open Platform Management Architecture''' (OPMA) is an open, royalty free standard for connecting a modular, platform hardware management subsystem (an "mCard") to a computer motherboard. Platform hardware management generally refers to the remote monitoring of platform hardware variables such as fan speed, voltages, CPU and enclosure temperatures along with a wide range of other sensors. It also implies the ability to remotely control the power state of the platform and to reset the system back into an operational state should it "hang". A significant advantage of OPMA over previous generation management subsystem attachment methods is that OPMA does not consume a PCI socket. OPMA cards are also smaller and lower cost than their PCI predecessors.

Coincident with the above, AMD was seeing a dramatic increase in interest for its [[Opteron]] series of server processors. As a result, AMD engineering teams were internally tasked with building server reference designs to support Opteron evaluation by customers. During these early internal server design efforts it was determined that a standard management card subsystem that was reusable across many platforms would decrease time to market while saving design and support costs for AMD reference design platforms in the field. Such an interface would also allow AMD to outsource the design and test of the management card to industry experts. AMD reasoned that external audiences would derive these same benefits as its internal engineering teams and so OPMA was documented and released. Since the initial release of the OPMA specification there has been [http://www.amd.com/us-en/Weblets/0,,7832_8366_7595~102307,00.html significant uptake]by the server industry platform and infrastructure providers.
