[Scst-devel] FC target question(s)

[Joe L. <la...@sc...>]

Hi folks:

   This is more of a high level use case question for the FC targets, I 
want to make sure I have my mind wrapped correctly around this.

   We are looking at how to provision multiple FC targets for users. 
The  connectivity we have envisioned for this is something like this

[ storage box with FC ] <----> { FC switch } <----> ( FC initiator )

Question 1: The FC target(s) is(are) visible over the FC connection, and 
not the IB/GbE/10GbE connection ... is this correct?  I know there is 
work going on w.r.t. FCoE and related.  Its tangential to this right 
now, but I presume we'd be able to leverage that atop the scst core as 
well (at some point)?

Question 2: We can use FC8 as well as FC4 HBAs I presume?  Is there any 
benefit to multiple HCAs for scst?  Load balance, etc?

Question 3: It looks like the Qlogic series are fairly well supported. 
Is there a list of supported HBAs and how well they are known to work?

Question 4: Is there anything preventing us from having multiple FC 
targets per storage box, or mixed FC/iSCSI/SRP targets per box (ignoring 
performance issues, I am talking specifically about the scst core itself)?

As I said, just trying to wrap my mind around this for some end user 
cases we are being asked to configure.  Thanks!
