I'd like specifics (ie: controller >card, raid level, raid subsystem - # drives, type of drives, and also >what you use it for). <SNIP> A follow-up to my own post to share some info. I've read through archived mailing list posts at www.freebsd.org and have found the following: 1) DPT drivers may/may not be coming out any day now... 2) Adaptec drivers are already available (ie 2940U/UW) Stable? 3a) In order to implement SCSI: a) You will need a supported SCSI controller card (ie, adaptec 2940UW) b) A SCSI-to-SCSI raid controller (ie mylex DAC960SU) c) connect the two together along with any associated cabling/chassis/etc... Voila! now you have RAID. 3b) The reason for SCSI-to-SCSI solution is due to the fact there exists no direct support for a RAID SCSI controller card. The Mylex DAC960SU/SUI seems like a good choice as any for a scsi-to-scsi configuration. Any comments on this info? TIA Susan10
