I'm the driver writer for the QLogic FC cards in FreeBSD. It works, with varying success, with Vixel, Gadzoox and other hubs in private loop mode (for Qlogic 2100s and 2200s). It works in public loop and point-to-point topologies with Brocade and Ancor SA-8 fabric switches. Both the Brocade && Ancor doing aliasing, so the 2100 should work on fabrics as does the 2200. However, your mileage may vary on that one. FC-IP should be integrated in the next month os so. The same driver also supports Ultra, Ultra2 and Ultra3 cards. Target mode is supported, but not well shaken out in SPI. I have not had the opportunity to try the EMC hardware to validate how well this works or not. Typically, the problems often revolve around firmware issues in the QLogic card that can't often be gotten around. I have a sample LSI-Logic Fibre Channel card that I hope to have a driver in FreeBSD for in a couple of months. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
