Most PERC PCI SCSI RAID controllers are AMI. Motherboard and SATA are often adaptec (or there are some low-end Promise pseudo-RAID SATA too). > Does HP, IBM, or anyone else provide a 1u rack mount server with > hardware raid that is fully supported by OpenBSD? HP RAID cards are usually ciss(4) with some support in 3.8 but no bioctl yet. IBM mostly use Adaptec for RAID. Fujitsu-Siemens have MegaRAID PCI cards. Motherboard generally mpt(4), marco@ recently put out a call for hardware to work on the raid part of mpt (IM 'intelligent mirroring'), though a recent poster here said that adding RAM (or was it BBU..can't remember) to the motherboard RAID on the F-S turns it into an ami(4) for much less cost than a PCI card. Looks like Sun v20z and x4100 onboard is mpt(4), as above. They also do MegaRAID PCI cards. You might see a pattern forming: you mostly need a PCI raid card for support by existing OpenBSD code. Look at the -current manpage or OpenBSD website for a better list of ami(4) cards than previously available. > Or do I have to go to each vendor and get them to tell me the chipset > for each part? If you find something you think you'll buy, it wouldn't hurt to get vendor confirmation about this (and anything else you're concerned about - e.g. motherboard chipset).
