It will register:

•Platform’s:

–Worldwide node name (node name for the platform - same for all channels)

–Platform type (host computer)

–Platform name (includes vendor ID, product ID, and vendor specifi c data from the node descriptor)

•Channel’s:

–Worldwide port name (WWPN)

–Node port identifi cation (N_PORT ID)

–FC-4 types supported (always 0x1B and additionally 0x1C if any Channel-to-Channel (CTC) control units are defi ned on that channel)

–Classes of service support by the channel

Platform registration is a service defi ned in the Fibre Chan- nel - Generic Services 4 (FC-GS-4) standard (INCITS (ANSI) T11 group).

Platform and name server registration applies to all of the FICON Express4, FICON Express2, and FICON Express features (CHPID type FC). This support is exclusive to System z10 and is transparent to operating systems.

Preplanning and setup of SAN for a System z10 environment

The worldwide port name (WWPN) prediction tool is now available to assist you with preplanning of your Storage Area Network (SAN) environment prior to the installation of your System z10 server.

This standalone tool is designed to allow you to setup your SAN in advance, so that you can be up and running much faster once the server is installed. The tool assigns WWPNs to each virtual Fibre Channel Protocol (FCP) channel/port using the same WWPN assignment algo- rithms a system uses when assigning WWPNs for channels utilizing N_Port Identifi er Virtualization (NPIV).

The tool needs to know the FCP-specifi c I/O device defi ni- tions in the form of a .csv fi le. This fi le can either be cre- ated manually, or exported from Hardware Confi guration Defi nition/Hardware Confi guration Manager (HCD/HCM). The tool will then create the WWPN assignments, which are required to set up your SAN. The tool will also create a binary confi guration fi le that can later on be imported by your system.

The WWPN prediction tool can be downloaded from Resource Link and is applicable to all FICON channels defi ned as CHPID type FCP (for communication with SCSI devices). Check Preventive Service Planning (PSP) buck- ets for required maintenance.

Extended distance FICON – improved performance at extended

distance

An enhancement to the industry standard FICON architec- ture (FC-SB-3) helps avoid degradation of performance at extended distances by implementing a new protocol for “persistent” Information Unit (IU) pacing. Control units that exploit the enhancement to the architecture can increase the pacing count (the number of IUs allowed to be in fl ight from channel to control unit). Extended distance FICON also allows the channel to “remember” the last pacing update for use on subsequent operations to help avoid degradation of performance at the start of each new operation.

Improved IU pacing can help to optimize the utilization of the link, for example help keep a 4 Gbps link fully utilized at 50 km, and allows channel extenders to work at any dis- tance, with performance results similar to that experienced when using emulation.
