[zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller ?
Does anyone know if the current OpenSolaris mpt driver supports the recent LSI SAS2008 controller? This controller/ASIC is used in the next generation SAS-2 6Gbps PCIe cards from LSI and SuperMicro etc, e.g.: 1. SuperMicro AOC-USAS2-L8e and the AOC-USAS2-L8i 2.

Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
I'm about to try it! My LSI SAS 9211-8i should arrive Monday or Tuesday. I bought the cable-less version, opting instead to save a few $ and buy Adaptec 2247000-R SAS to SATA cables. My rig will be based off of fairly new kit, so it should be interesting to see how 2009.06 deals with it all :) -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It won't, however, be detected by a 2009.06 installation, since that was based on build snv_111b, and the mpt_sas driver wasn't introduced until build snv_118.

Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
So I did manage to get everything to work after switching to the Dev repository and doing a pkg image-update, but what happens when 2010.$spring comes out? Should I wait a week or so after release and then change my repository back to standard and then image-update again? I'm new to Osol; sorry for the newbie-ish question and the slight derailment. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
Thanks a lot for the info James. For the benefit of myself and others then: 1. mpt_sas driver is used for the SuperMicro AOC-USAS2-L8e 2. mr_sas driver is used for the SuperMicro AOC-USAS2-L8i and LSI SAS 9211-8i And how does the maturity/robustness of the mpt_sas & mr_sas drivers compare to the mpt driver which I'm currently using for my LSI 1068-based AOC-USAS-L8i card? (in the default IT mode) It might be hard to answer that one, but I thought I'd ask anyway, as it would make choosing new kit for OpenSolaris + ZFS a bit easier.

I really don't have any specs re maturity or robustness, sorry, but I can tell you that (a) these two drivers were joint development efforts between Sun and LSI, (b) the requirements list that we had for the drivers is extensive, [note that MPxIO is on by default with mpt_sas] (c) we went through an insane amount of testing (and with some very rigorous tools) at every stage of the cycle before integration, and (d) we're confident that you'll find these drivers and chips to be up to the task. If you do come across problems, please bring it up in storage-discuss or zfs-discuss, and if necessary file a bug on bugs.opensolaris.org solaris/driver/mpt-sas, and solaris/driver/mr_sas are the two subcats that you'll need in that case.

I could always use the 'try before you buy' approach: others try it, and if it works, I buy it ;-) Thanks a lot.

Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
We tried the new LSI controllers in our configuration trying to replace Areca 1680 controllers. The tests were done on 2009.06 Unlike the mpt drivers which were rock solid (but obviously do not support the new chips), the mr_sas was a complete disaster. (We got ours from LSI website). Timeouts, missing drives, errors in /var/adm/messages. The driver may have stabilized since then, but I wouldn't use it in production yet. 2010/03 - may be, but not 2009.06 -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
Ouch. Was that on the original 2009.06 vanilla install, or a later updated build? Hopefully a lot of the original bugs have been fixed by now, or soon will be. Has anyone got any "from the trenches" experience of using the mpt_sas driver? Any comments?

Those aren't sorry for any misunderstanding. They are from the LSI site - http://lsi.com/storage_home/products_home/internal_raid/megaraid_sas/6gb_s_value_line/sas9260-8i/index.html since 2009.06 didn't have them integrated yet. What i was trying to say is that the current release of OS is not yet ready for those controllers. Dev versions/ 2010.03 may work great with them, but the current release doesn't. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Does OpenSolaris mpt driver support LSI 2008 controller
OK, gotcha. Relating to my request for robustness feedback of the other driver, I was referring in fact to the mpt_sas driver that James says is used for the non-RAID LSI SAS2008-based cards like the SuperMicro AOC-USAS2-L8e (as opposed to the RAID-capable AOC-USAS2-L8i & LSI SAS 9211-8i cards, which use the mr_sas driver). As far as I'm aware, the standard mpt driver is used for the card I already own, the LSI SAS1068E-based AOC-USAS-L8i etc. Cheers, Simon http://breden.org.uk/2009/05/01/home-fileserver-a-year-in-zfs/ -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
