Alan, I wonder why you make your final point below.
4. Reduces the temptation to share OSA ports (VSWITCH + TCPIP) What's the downside of sharing an OSA between the z/VM IP stack and the VSWITCH? Regards, Mike Wawiorko Global z/OS Connectivity and Service Management Barclays Bank Email: mailto:[email protected] P Please consider the environment before printing this e-mail -----Original Message----- From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Alan Altmark Sent: 16 February 2010 20:55 To: [email protected] Subject: Re: VSWITCH Billy, if you haven't already done so, please look at the z/VM Connectivity book. I suggest that TCPIP be given a virtual NIC on the VSWITCH rather than dedicating an OSA for these reasons: 1. VSWITCH has better OSA stall detection than TCPIP 2. No need for dynamic routing daemon and VIPA 3. No need for additional IP addresses 4.
