Parent article: A tale of two SCSI targets

Thanks for the writeup. Even for those of us who are close to the action, it is difficult to get an overview. One small criticism: the title should be "A tale of two iSCSI targets". Explaining the term "SCSI target" is difficult and the definitive document (SAM-5) does not help in that regard. iSCSI is one of many SCSI transports (and recently a new one was proposed: SOP (SCSI over PCIe)). So I question this statement: "The most common implementation of the SCSI target subsystem is an iSCSI server, ...". IMO USB (storage) keys are the most common (and worst) implementation of the SCSI target subsystem.

I suspect that he meant a SCSI target implemented in linux. I could be wrong, but I doubt those USB storage keys are running linux (yet), are they?

SCSI target, iSCSI target or SCSI target framework ?

Maybe A tale of two SCSI target frameworks would be a better title ? While LIO started as an iSCSI target (and its source code still shows this), SCST has been designed from the start as a generic SCSI target framework.

But isn't SCSI target framework about much more than iSCSI? Like Solaris's COMSTAR http://hub.opensolaris.org/bin/view/Project+comstar/WebHome ?
