Whether 'old' or 'new' OSA Express 1000BASE-T features, its always been the case i.e. one CHPID for 2 ports.
When it comes to 'FICON' features, there has been a change with the latest feature i.e. FICON Express16S+. See below. For both OSA and FICON features, the 'old' ones had a different form factor. When the PCIe architecture was introduced. the form factor changed and the number ports were halved. All OSA/FICON and Crypto features with an 'S' are the 'new' form factor. OSA Express4S and newer, FICON Express8S and newer have the newer form factor. OSA Express4S 1000BASE-T and newer, 2 ports/one CHPID OSA Express4S 1 GbE and newer, 2 ports/one CHPID. These features are either LX or SX. OSA Express4S 10 GbE and newer, 1 port/one CHPID. These features are either LR or SR. FICON Express8S and FICON Express16S, 2 ports/2 CHPIDs. Each Port can be either TYPE=FC or FCP or both can be TYPE=FC or FCP For the latest FICON Express16S+, 2 ports/2 CHPIDs. The main change here is that BOTH ports have to be either TYPE=FC or FCP. Can't have a 'mix' of TYPEs on the same physical card. In addition all FICON features are either LX or SX. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
