OIF Adopts Common Management Interface Specification (CMIS) Work Initiated by QSFP-DD Multi-Source Agreement
Taking on the CMIS work reinforces and increases OIF’s significant value to the ecosystem
Fremont, Calif.—January 5, 2022 – OIF is expanding its role in driving industry interoperability through the addition of the Common Management Interface Specification (CMIS) work initiated by the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA).
CMIS may be used by pluggable or on-board modules, such as QSFP Double Density (QSFP-DD), OSFP, COBO, QSFP, and future module developments like co-packaged optics with host to module management communication based on a two-wire interface. This specification is targeted to systems manufacturers, system integrators and suppliers of CMIS compliant optical and copper modules.
“The QSFP-DD MSA initiated the CMIS effort to address an industry need for commonality in managing pluggable modules, and it has been broadly and successfully adopted across the industry,” said Mark Nowell, Cisco, QSFP-DD MSA Group founding member and MSA co-chair. “OIF is very well suited to maintain and extend the development of this effort and I look forward to seeing their progress.”
“Adopting CMIS from the QSFP-DD MSA, with the goal to build on and extend the specification is an ideal expansion of OIF’s work,” said Nathan Tracy, OIF VP of Marketing and TE Connectivity. “OIF is where the cloud gets its work done and extending CMIS is a giant step forward and an integral linkage to the other work that OIF members are doing to enable an interoperable ecosystem.”
In August, OIF announced the new Physical & Link Layer (PLL) Working Group Management track to include the transition of ownership and maintenance of CMIS from the QSFP-DD MSA to OIF and a project to focus on CMIS extensions for co-packaging implementations. OIF will take over the ongoing CMIS revisions and further enhancements and CMIS extensions under this track. This track is co-vice-chaired by Gary Nicholl, Cisco and Ian Alderdice, Ciena.
“OIF’s value to the industry is deep, as proven by the industry’s support and endorsement of this transfer of the CMIS work to OIF,” continued Tracy.
The current CMIS and prior revisions (from QSFP-DD MSA) are now available to members on the OIF website. “Archived Non-OIF Generated Specifications” can be found on the home page, on the “Documents” pull-down menu.
