No. It means that HiperSockets support VLANs, allowing you to segregate traffic on a single HiperSocket chpid. There is no OSA-HiperSocket bridge in the VSWITCH. > Also IB announced "Layer two Switch Support" "You can now integrate > hipersockets-connect operating systems into external network, without > requiring intervening network routing overhead... which can > transparently bridge traffic between a HiperSockets internal LAN and an > external OSA-Express network.. > this support can make the internal HiperSockets network address > connection appear as if it was directly connected to the external network". > > Doesn't this mean a seamless subnet from host on real switch to host on > lpar b going through a vsiwtch to lpar a through a hipersocket to lpar b? No. It means seamless subnet using the "Layer two Switch Support" in Linux. Do not confuse a Linux-based layer 2 switching function with the z/VM VSWITCH. This used to be known as the HiperSockets Network Concentrator, and is the same function as z/OS's Hipersocket Accelerator. Neither of the announcements affects the VSWITCH.
