With your permission (I hope :-), I am forwarding this question to the FreeBSD-SCSI group, too. A patch against current can be found in ftp://nomis.i-connect.net/crash. Pick up the patch of the 13th, not the 14th (which is buggy). You can find a boot floppy in the various release builds in /FreeBSD, in the usual place. The source should have been committed long ago and is quite stable. Maybe in the next few days. No, there is no web page as I do not know how to create one. Too lazy to learn too :-( The current driver supports all the DPT PCI controllers shipping currently, does not support the software RAID (so you cannot span controllers and cannot create multi-driver RAID-1. These can be acomplished easily and probably almost as well with ccd. Initial support for multi-initiator and distributed/shared I/O is present and this support will increase daily in the next week or two. There is an Alpha release of a DLM included in the patch, but the connection between the two is still missing. Thsi iwill be closed in the next few weeks. The driver (aside from the MI code, is rather stable, went through extensive code review and is capable of about 1,742 I/O operations per second per HBA, when talking to a PM3334UW. Now you know :-) --- If Microsoft Built Cars: There would be an "Engine Pro" with bigger turbos, but it would be slower on most existing roads.
