Differential vs. Single-Ended is a cable electrical signal issue, no a softwae issue. Any controller which the vendor build in differentical as well as single ended will work. Some new controllers use what is known as ``low voltage differential'' with means the controller (correct name is HBA) will ``talk'' differential to differential devices, single-ended to SE devices. Most DPT (http://www.dpt.com) controllers are available either way, with the PM3335UDW giving you RAID and 3 SCSI busses in a single PCI slot. > > Thanks!! > > -- > Eddie Fry > EAZNet Internet Services > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-scsi" in the body of the message Sincerely Yours, Shimon@Simon-Shapiro.ORG 770.265.7340 Simon Shapiro Unwritten code has no bugs and executes at twice the speed of mouth To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
