2017 OFA Workshop

About the Workshop

March 27 - 31, 2017
Hyatt Regency Austin
Austin, TX. U.S.A

An ongoing collaboration between OpenFabrics Software (OFS) producers and users is necessary to address difficult network challenges. The 13th Annual OpenFabrics Alliance (OFA) Workshop is a key industry event encouraging a dialogue that is geared toward strengthening high-performance networks end-to-end and represents a joint effort among open source networking community members.

The Workshop is driven by the needs and interests of the attendees and, as a result, the audience profiles continue to expand. Attending software developers and distributors are now joined by a growing number of OFS consumers including:

• Application end users
• Enterprise data center managers
• Network technology researchers
• Networking middleware developers
• Operating system vendors
• Storage vendors
• System & network administrators
• System OEMs, architects & integrators
