SMB3 Multi-Channel in Samba ... Now Really!

Event: sambaXP 2016

Submission Type: Presentation

Category: Developer

Abstract:

Multi-Channel is arguably the most universally useful feature of SMB3
that can be enabled as a capability: It applies to both clustered and
non-clustered servers and is the prerequisite for supporting RDMA
transport with SMB Direct.

I have presented about SMB3 Multi-Channel in Samba a couple of times
by now, have presented on ideas, designs and even demoed early
prototypes. Now the impending version 4.4 of Samba wil finally bring
Multi-Channel to the filed! (Small print: The majorty of the code
has been merged upstream, and we are currently working hard to
complete the missing pieces for Samba 4.4.0.)

After recapping teh basics of Multi-Channel, the talk will explain
Samba's implementation, addressing challenges and how they have been
solved. It then details on the recent developments in the area.
Also, the challenges of integrating Multi-Channel with Samba's
CTDB clustering are discussed. The presentation will contain a demo
of the latest code.
