Hey, if someone here had all the answers already then there was no need for 4 people 5 weeks in Poughkeepsie... a few cents of mine: You can use HiperSockets to do IP between your LPARs. You could also do that with an OSA Express card shared between the LPARs but the HiperSockets is faster and does not cost your devices on the OSA. You need someone else to tell if these MVS versions do that. One OSA Express gets you up to 83 IP stacks, so plenty to give each Linux image its own, however: - virtualisation of the QDIO by z/VM is relatively expensive at low bandwidth - root can set the IP address of the Linux image, not something you want to give away to customers maybe - the qeth driver is still object code only which means you must run a kernel for which IBM supplies a working driver So it may be wise to set up a virtual router (Linux or VM TCP/IP) to provide access to your Linux images. You could do Guest LAN to let the Linux images talk to the virtual router and (if you can live with the OCO issue) or IUCV of virtual CTC connections. If Linux images have very high bandwidth requirements it might make sense to give them their own OSA device. If some Linux images talk a lot to each other it may help to have a private p2p connection for that rather that burn cycles in your virtual router. > Are there any good presentations that will help me????? I hope so, in La Hulpe - but that's not for me to judge ;-) Rob
