VLAN, VSWITCH, HiperSockets
I'd like to move all of our internal communications internally. Basically this consists of TCP/IP for z/VM and several z/VSEs. This includes PNET between z/VSEs. What would you recommend? I'm leaning toward HiperSockets. Pros Cons? Frank M. Ramaekers Jr. Systems Programmer MCP, MCP+I, MCSE RHCE American Income Life Insurance Co.

Re: VLAN, VSWITCH, HiperSockets
If the VSE's are guests on zVM - use VSWITCH. If they are LPARs -- then either hipersockets or maybe a shared OSA port (which can be uncabled).. Scott On Thu, Oct 29, 2009 at 9:31 AM, Frank M.

Re: VLAN, VSWITCH, HiperSockets
If the VSE's are running in the same z/VM system then use the VSWITCH. If they are not, but in the same CEC, use hipersockets. Frank M.

Re: VLAN, VSWITCH, HiperSockets
If they're VM guests, use VSWITCHes. Only use hipersockets if you have to cross LPARs. Hipersockets are a giant PITA to define and maintain. On 10/29/09 4:31 PM, Frank M.

For others, or for backlevel systems that can't do layer 2, use IP. The ethernet ones tend to use a little more CPU since the ARP processing has to be done in each virtual machine vs having it suppressed in the IP type VSWITCH. If you do (or plan to do) IPv6, then you're going to want the layer 2 stuff.
Re: VLAN, VSWITCH, HiperSockets
I can find no indication that z/VSE supports ETHERNET (layer 2) mode yet. Frank M. Ramaekers wrote: ETHERNET or IP? Advantages/disadvantages? Frank M.
