Gregory: It does help. As a VSWITCH it can be protected by RACF hence the VLANs can be RACF protected too. Another advantage is that it uses only one hipersocket triplet whereas dedicated hipersocket will end up using one triplet per Linux virtual. You can even use the same hiper triplet on each LPAR. There is a limit to how many LPARs can connect to the hiper. I've been scalded by this a few times. David

HiperSocket VSWITCH Bridge will not help when it comes to isolation, right? Vswitch simply acts as a bridge for hipersocket network using using one of the real hipersocket devices as one of its own interfaces (bridge port). Via this bridge Hipersocket network gets access to external network but doesn't give more control on who can talk to who inside of CEC, does it? thanks Gregory 2015-11-20 0:47 GMT-05:00 Alan Altmark <alan_altm...@us.ibm.com>: > On Thursday, 11/19/2015 at 08:35 GMT, Grzegorz Powiedziuk > <gpowiedz...@gmail.com> wrote: > > I thought about doing vswitch but then AFIK I would end up with with > > virtual hipersockets on linux guest. > > Linux guests can use real HiperSockets with the HiperSocket VSWITCH bridge > on z/VM.
