Hi, I don't get some DELL servers but I have one server with an Adaptec 5400s SCSI Raid Adapter.
Two years ago, I first began by installing Linux 2.4.x on this machine and got the worst problems of my Unix life. I could just install one Linux distribution ( Fedora, Mandrake, ... ) and after two minutes delay, I always had system crash. After a few reboots my filesystem was completely corrupted. So I decided to solve this problem and had long (very long ) discussions with the aac module driver developers and mainly with Alan Cox but the debugging was painfull. I tried many kernel snapshots without any stable solution. So, after 4 months, I decided to test FreeBSD 4.x because I urgently had to setup a website architecture and never got problem with it. So I can confirm that the FreeBSD aac driver implementation is the most stable until now.

However they only provide documentation if you sign an NDA, which is unacceptable for any free software. Second, all the PERC4 cards Dell uses are no longer Adaptec, but LSI Logic (unless they've changed again reciently), which is fully supported in OpenBSD, including completely open management utilities. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of > Jan Johansson > Sent: Tuesday, September 20, 2005 8:14 AM > To: Ryan Rothert > Cc: misc@openbsd.org > Subject: Re: Dell PowerEdge 2650 > > Ryan Rothert <[EMAIL PROTECTED]> wrote: > > 3.6 will install on it.
