2 SM Axiom All problems are SM problems until proven otherwise

3 OpenSM  IB router infrastructure  Router port handling  Extend PathRecord & MCMemberRecord  Subnet Administration (SA) Enhancements  SA database dump/restore  InformInfo improvements  InformInfoRecord  Possibly other optional records currently not supported (SMInfoRecord, SwitchInfo, …)  MultiPathRecord 1.2 errata support Done Jan 2007 Dec 2006 Jan 2007 TBD Aug 2007 Now

4 OpenSM  Modular routing for multicast  Additional routing algorithms  Eitan’s algorithm  Simula (torus routing)  Weighting support for link load balancing  SDR/DDR, 1x/4x/12x  Daemon improvements  Command line interface  Local events handling ?  NodeDescription changed trap handling TBD Dec 2006 Mar 2007 Jun 2007 TBD

5 OpenSM  Quality of Service Manager  Performance Manager  Advanced Failover  Berkeley DB as backend ? Aug 2007 TBD

6 Diagnostics  LID and GUID on output of diag to make it easier to grep  Peer port characteristic checking  ibportstate enhancements  Detect additional fabric inconsistencies  Ibdiagui  New Mellanox contribution Apr 2007 TBD Apr 2007 Done Apr 2007

7 Summary and Shameless Plug  My good fortune for over 2 ½ years  DoE  Voltaire  SC and other metrics  Upcoming year challenges  Many consumers/testers/environments now and growing all the time  More (developer) contributors needed

8 Backup

9 OpenSM Daemon Mode  Stdout/stderr redirection  Merge with logging  Daemon attributes  Terminal detaching  Session leadership  Reforking to background  Handle log rotation while running  Unified and refreshable configurations  Rather than cached options  Better threads handling especially termination and synchronization

10 OpenSM Command Line Interface  Unification with diags tools  Common getopt() wrapper  Unified extension per utility for specific options  Command line/config for OpenSM  Command line options/config parameters unification into single config module with different interfaces  Command line  Config file  Console  Future possibilities  SMTP  GUI  getopt() wrapper (as command line interface)  Config parser, loader, and reloader  Support for dynamic config parameter changing in OpenSM

11 Assumptions for IB Router Simplification  Assumptions for simplest static router  Similar Pkeys  Similar SLs  Well known MGIDs
