I'm studying the picture on page 161 of the OSA-Express Implementation Guide http://publib-b.boulder.ibm.com/Redbooks.nsf/9445fa5b416f6e32852569ae006bb65f/78796993019dfafe85256c38006f1d4e?OpenDocument&Highlight=0,osa
Right now I have a two levels of routers/firewalls in out penguin farm. One single "master" router on the top level and four second level routers/firewalls for each of the guest lans. The master level router has the OSA dedicated to it via the VM user directory. I want to get rid of the master level router because it does burn quite a few cycles handling all the traffic and with the coming virtual switches in VM 4.4 (yahoo!) I think a redesign and a re-think of our external network interface is needed. So, page 161 shows a picture of four Linux machines connected to a single OSA (port). Since the OSA supports trunking and zLinux can handle it as well, I want to set up VLANs - like in the picture. How do I share the OSA between four (or more) Linux guest images? Are we talking IODF/IOCDS changes? Creating more CHIPDs/devices to be deicated to each Linux? When I read the text, the implementation doesn't jump out at me.
