SMB3 Interoperability Lab

SMB3 Plugfest

The SNIA SMB3 Interoperability (IO) Lab will take place Monday, September 18 through Thursday, September 21, 2023, co-located with the Storage Developer Conference (SDC) in Fremont, CA.  The purpose of the IO Lab is for vendors to bring their implementations of SMB3 to test, identify, and fix bugs in a collaborative setting with the goal of providing a forum in which companies can develop interoperable products.  The SNIA provides and supports networks and infrastructure for the IO Lab, creating a collaborative framework for testing.  The participants of the IO Lab work together to define the testing process, assuring that objectives are accomplished. There are several new features that have recently been added to the SMB3 protocol:

  • SMB over QUIC support for mutual authentication.
  • Server Notification update for logon session scenario (when server discards a logon session before client).
  • Significant Windows security behavior defaults updates in certain Windows releases:
    • SMB Signing required by default.
    • Auth rate limiter on by default.
    • Guest auth fallback now off by default.
    • Mailslots off by default and SMB1 now disabled in all Windows releases.
  • And other SMB security updates and features…

The IO Lab is an opportunity to learn about these new features and test your implementation with Microsoft Windows protocol test suites.  During the IO Lab you have the opportunity to directly engage with Windows Protocol Support, Test Suite Development, and members of the Windows development team as well as network with other professionals from all over the world.

In addition the SNIA SMB3 IO Lab offers access to:

  • The latest Windows client and server software from Microsoft, including test suites that help verify interoperability on various features of SMB3 protocols
  • Technical support from SMB3 engineers to look at traces and help with diagnosing problems
  • IO Lab participants are covered by a non-disclosure agreement and access is restricted to registrants only
  • As in previous years, we will open the Interoperability Lab to all SDC attendees for a reception on Monday evening, as an open house for an insider’s view

If you are reluctant to participate because you feel that your SMB implementation is "not ready", you should still participate! The SMB IO Lab is also a development opportunity, not just a testing opportunity. Implementations still in development are encouraged to participate.  It's a great opportunity to get help and learn from the experts!

How Your Company Can Participate

A primary representative from each company that wishes to participate must complete the SNIA SMB3 IO Lab Company Registration.  The fee to participate in the SMB3 IO Lab is $695 for each IO Lab participant. This includes full access to the Storage Developer Conference sessions and meals. This special discounted rate is limited to participants that will actively participate and test, working with the other SMB3 IO Lab participants. If any of your IO Lab Engineers already have an SDC Conference pass from being a speaker or through sponsorship then there is no fee for them to participate, however the SNIA SMB3 IO Lab Company Registration form still needs to be completed.

Once the online registration form has been completed the company primary representative will be sent a registration code which will allow the company’s IO Lab Engineers to register for SDC at the special discounted rate.
