You can define multiple network interfaces, of various types, for any one Linux system. This may be desirable for things such as routing some traffic over a HiperSocket to z/OS or z/VSE, while routing other traffic only between the Linux guests via a "private" guest LAN or disconnected VSWITCH, and the remaining traffic outside of the box. There are lots of possibilities there. > For z/OS we have one VIP and several OSA cards.

Yes, but primarily useful for LPAR installs, not on z/VM. With z/VM, you can get similar benefits to VIPA without all the hassle. If you have a need for more network bandwidth than can be delivered via one real OSA, then you need to have z/VM 5.3 installed for the network link aggregation support it can provide. The only real caveat there is that any OSA port involved in link aggregation cannot be shared with other LPARs.
