Broadcom/Avago has put out a new generation of mpt_sas parts that have what they call tri-mode support. In other words, SATA, SAS, and NVMe. We'd like to support this newer generation of parts, though we're not bothering with the NVMe related bits. This updates us to the MPI 2.6 specification (which is backwards compatible with the older parts).

This includes support for the following chipsets (that are MPI 2.6, not all are tri-mode):

  • SAS3216
  • SAS3224
  • SAS3408
  • SAS3416
  • SAS3508
  • SAS3616
  • SAS3708
  • SAS3716

For testing, we performed I/O and scrubbed on four different controllers:

  • 2008
  • 2308
  • 3008
  • 3408

I/O was performed with iostomp with a 128k record size and then after 10-20 minutes of I/O, a scrub was performed. For the 3408 I/O and scrubbing was performed over a 24 hour period.

In addition, we verified that the mpt_sas topo plugin worked and that the ses targets were functional and returned the same information as previously.

In addition, on the 3408, I did a lot of I/O testing while disk pulls were performed and verified that the system continued to function.
