Recent Alert doc - ConnectX-2 IB HCA with later version of IB Switch firmware

edited Jul 22, 2015 11:49PM in Network Switch and Interconnect (MOSC)

For customers with Oracle/Sun Infiniband Switch, please be aware of the following Alert document (released in early June 2015) for a solution that may be helpful to customers with heavier load/traffic profiles:

Solaris 10, Solaris 11 and ZFS Storage Appliance (ZFSSA) Software May Experience InfiniBand Port Failure with InfiniBand Switch Software 2.1.3-4 During Heavy I/O Load (Doc ID 2017896.1)

The issue arises in conjunction with later versions of InfiniBand (IB) Switch firmware (revision 2.1.3-4 and later) which introduces a change that may cause certain patch and update levels of Solaris 10, Solaris 11 and ZFS Storage Appliance (ZFSSA) Software systems (as listed in the document), with older IB HCA ConnectX-2 Card revisions of firmware, to experience InfiniBand port failure, with the port going up and down repeatedly ('flapping') and causing performance issues during periods of heavy I/O load.

Howdy, Stranger!
