EISA RAID controller a while back, I was fascinated when I ran across the following: (from http://www.adaptec.com/sales/AHA3985Features.html) (snip)---------------------------------------------------------------- Adaptec AHAŽ-3985 PCI RAID Adapter Delivers high performance through innovative multiprocessing RAID architecture Provides three independent SCSI I/O channels Supports multiple RAID levels 5, 1, 0, 0/1 (snip)---------------------------------------------------------------- The unit looks a little pricey ($750ish) but that's not entirely out of line for a 3-channel controller, considering the 3940's around $400. Does anybody have any further information about this? (is anybody looking to write a device driver for it???) All FreeBSD needs now is a PrestoServe type solution (the one advantage of the Compaq controller) ... I can just see it now. Pentium, of Borg, materializes, saying "Sun is Irrelevant", holding a FreeBSD 2.2 CDROM and a FreebieServe Cache Accelerator card :-) ...
