I'm having a similar problem trying to get our X4240 servers to accept an SSD disk that I wanted to use as a log device for our ZFS filesystems...
The easiest way I've found to generate a lot of error messages on the console is to use the SSD disks as a lone disk in a ZFS pool, export it to another machine via NFS, and then on that remote machine untar the emacs-22.3.tar.gz archive (generates a lot of small files written :-). One thing to note though: It only fails when using the LSISAS1068E HBA. When using the Adaptec RAID HBA things seems to work fine! (but that card has other limitations that are a bit annoying) Ie, on machineA (an X4240): zpool create TEST c1t15d0 zfs set sharenfs=rw,root=machineB TEST chmod a+w TEST On machineB: mount machineA:/TEST /mnt cd /mnt /usr/sfw/bin/gtar zxf /home/build/gnu/emacs/emacs-22.3.tar.gz Wait a little while and then watch the disk errors scroll by on machineA's console I've tried to used both Intel X25-E (32GB) and Intel X25-M (80GB) SSDs devices. Both fail the same way. Note though that _reading_ data from the disks seems to work perfectly fine. I ran some tests using my own program and both drives seems to be able to read around 310MB/s (atleast for the first 8-10 gigabytes or so) when using the LSI SAS1068E HBA. Down to around 240MB/s when using the Adaptec HBA. The X4240 is now running Software 2.3 that was supposed to fix the SSD issues, but that didn't help for us atleast. - Peter -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
