In fact, nearly all of the testing I do is *with* fabric. This has led me to miss a couple of FC-AL bugs. Oops. THe 2100 actually can work on any switch that support both public loop &AND& provide aliasing (Brocades && Ancors do). The 2100 only has hardware to insert 8 bit AL_PAs (the low 8 bits of a D_ID) into frames, but the switches add the rest. The QLA2200 is supported (and has full 24 bit D_ID addressing), and that also is known to work with the above switches and even the McData (which requires you to do an FC4 login). The switches must support the SNS subcommand of GET ALL NEXT - that's how the fabric is probed. Also, the login policy is in the HBA, not in the upper layers, and is a "First Come, First Logged into" policy. There's room for 253 devices in the QLogic 2X00. The 2100, or the 2200 in FL-port configuration, can only support fabric devices from ids 129..255 (the way this works is that the QLogic f/w automatically logs into local loop members- but fabric devices you have to explicitly log into), but the 2200, connected as an F-port, can also use up slots 0..125. -matt On Thu, 24 May 2001, Lauri Laupmaa wrote: > Hi > > Is there any fibrechannel cards which have switch fabric support under > FreeBSD ? > I know that qla2100 has fc-al support... > > -- > L. > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-scsi" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
