Right now there's no NetBSD driver for either SAS 5/iR or PERC 5/i. I have one
server with PERC 5/i so right now I'm forced to use FreeBSD on it (with pkgsrc
of course :-).

This is other hardware RAID we have here:

Dell PowerEdge 1800 (CERC 1.5/6ch = hardware SATA RAID)
-------------------------------------------------------
aac0 at pci3 dev 9 function 0: Dell CERC SATA RAID 1.5/6ch

All these were with Dell provided RAID controllers. Then we have also few
servers with add-on RAID cards like this:

Dell PowerEdge 2400 (Adaptec 3200S = hardware SCSI RAID)
--------------------------------------------------------
iop0 at pci1 dev 6 function 1: I2O adapter <ADAPTEC 3200S>
iop0: interrupting at irq 5
iop0: configuring...
dpti0 at iop0 tid 0: DPT/Adaptec RAID management interface
ld0 at iop0 tid 522: <ADAPTEC, RAID-1, 370F> direct access, fixed
ld0: 17366 MB, 8820 cyl, 64 head, 63 sec, 512 bytes/sect x 35565568 sectors
ld1 at iop0 tid 523: <ADAPTEC, RAID-1, 370F> direct access, fixed


All these servers are "rock solid" running NetBSD 3.1. The disk speed is good
and I have had zero problems with these controllers (and now only 1 broken disk
since 1999 -- this happened last week on the PE2400 where one 72 GB disk failed).
