If you want to use the hardware HiperSockets to talk between LPARs, that will almost certainly give you the best network performance between those two nodes. Understand, however, that you will be limited to only so many connections. Even if you use the hardware HiperSockets, you will still probably want to use VSWITCH so that your Linux guests can talk to the rest of the network. If you get z/Journal, there is an article in the latest issue on planning and implementing VSWITCH for Linux guests. It includes all the z/VM setup so that things are "permanent."

I have Z/VM running with three Linux guests (sles9) sharing an OSA card in qdio mode. I also have hypersockets working within the zvm and one linux and two Z/OS 1.6 lpars. I need to add several more linux guest, but I do not want to keep sharing the osa card. I have been reading about the network setup using virtual lans, virtual switches, and just defining a hipersockets nic. I believe using hipersockets will give me better performance. Any one know differently? Would I be better off just defineing the nic with hiper and forget about all the virtual lan stuff? I read that you can do this, but it did not say how. If so How do I do this...be specific ...I'm new at all of this, Linux and VM. I know I can do these commands when logon as maint on vm, but where do I place them to be permanent. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
