Tony, Thanks for the correction. My mistake, I meant to say z9 BC and NOT z114.
As the Qs were related to channel type OSC and OSE, my answer was specific to the OSA-Express2 and 3 1000BASE-T (both supported by the z10 BC). Yes, there were other OSA features (10 GbE and 1 GbE) but these don't support channel type OSC. To avoid a 'chapter and verse' about OSA, in reality, by the time you take into consideration the different 'flavours' of the 10 GbE feature ( Long Reach and Short Reach) there were a total of 6 different 'bigger cards' (OSA-Express3) for the z10 BC. The bigger cards were actually 2 'small' cards with their own separate PCI-E adaptors. Each PCI-E adaptor supported 1 (10 GbE) or 2 ( 1 GbE/1000BASE-T) ports. The 2 port 1 GbE and 1000BASE-T features were a 'reduced cost' option for the z10 BC only with a single PCI-E adaptor - effectively making it a 'half' card (half full or half empty) but keeping the bigger card format. Irrespective of the number of 'ports' on the card, each PCI-E adaptor supported ONE PCHID/CHPID. I have also seen all the different I/O cards/features đŸ™‚ Regards Parwez Hamid​ ________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Tony Thigpen <[email protected]> Sent: 10 September 2021 17:12 To: [email protected] <[email protected]> Subject: Re: OSA Physical ethernet ports P H, z10 was generation before z114. It only supports the old/bigger cards. The large format OSAs came in four physical port layouts: 1 port at top (1 CHPID) 1 port at top and 1 port at bottom (2 CHPIDs) 2 ports at top only (1 CHPID) 2 ports at top and 2 ports at bottom (2 CHPIDs) (I have seen all 4.)
