Keyword: Licence policy of Adaptec. According to BSDI, the reason that the 3940UW is not supported is not a Adaptec issue, but in fact a BSDI issue. When you are thinking you are purchasing a "Grade A" OS, you expect to be able to run "Grade A" hardware. : -) Your posting shows up a major missunderstanding of the way SCSI works. : I'm pretty sure, that my systems provided with three SCSI controllers : will show up a better performance. I am very familiar with the way SCSI works. And having 3 controllers will do me no good considering I cannot find a motherboard with more than 4 PCI slots. Currently, I have 1 PCI slot for a scsi controller, one for a video card, and 2 for my ethernet devices. : I really want to see a SCSI bus having 15 working scsi devices on one chain. : By the way: You said "all the spools" Sorry, but what news software do : you want to use ? Or do you think about the ccd(4) driver ? I am referring to INND. Currently we have about 17gigs of HD space from 6 HD's. I want one chain to have sd0 (/ , /usr , /var) and sd1 (/var/news/etc). The other chain I would like to have my news spools (/var/news/spool, /var/news/spool/alt, /var/news/spool/ etc..etc..etc..) using 4gig(scsi). I have seen SCSI chains with 15 "working" scsi devices, and if you would like to make a trip to Chicagoland, I would be happy to get you a tour. : -) There are supported RAID systems. Yes, I have seen some RAID setups on BSD, unfortunately in order to get it to work properly, you have to jump up and down 3 times on one foot, while breathing through your nose, and bark like a dog 12 times to get it setup right. : -) BSD/OS is a real professional and commercial unix system. : In the unix market it's common FIRST to decide the unix version you want : to use. : If you choose HP-UX, you'll go and buy a HP system, ... (to be continued) : If you choose BSD/OS, you are strongly advised to buy the hardware : supported by BSDi. I bought BSDI before the adaptec cards were even really support well. I used buslogic for a couple years before migrating to adaptec. Yes, this is a commercial unix system, and BSDI has a responsibility to it's owners to keep up with technology. : -) Read the great papers written by Paul Vixie about good hardware for : BSD/OS systems. : -) If you really think, that a Linux driver will give you the throughput a : 3940UW can manage, continue with your dream. I was being sarcastic by saying I would use linux. I would never use linux. I did install freebsd on a system, and I am getting great performance out of the 3940UW, and is ready to go into production very soon. Ive read the papers by Paul Vixie, but it just comes down to what I believe to be acceptable performance for my network. DB
