z10 EC Frame and I/O Configuration Content: Planning for I/O

The following diagrams show the capability and fl exibility built into the I/O subsystem. All machines are shipped with two frames, the A-Frame and the Z-Frame, and can have between one and three I/O cages. Each I/O cage has 28 I/O slots.

General Information:

•ESCON confi gured in 4-port increments. Up to a maxi- mum 69 cards, 1024 channels.

•OSA-Express2 can be Gigabit Ethernet (GbE), 1000BASE-T Ethernet or 10 GbE.

•OSA-Express can be Gigabit Ethernet (GbE), 1000BASE-T Ethernet or Fast Ethernet.

•If ICB-3 is required on the system, it will use up a single I/O slot for every 2 ICB-3 to accommodate the STI-3 card.

Note: In the fi rst and second I/O cage, the last domain in the I/O cage is normally used for ISC-3 and ICB-3 links. When the fi rst 6 domains in an I/O cage are full, additional I/O cards will be installed in the next I/O cage. When all the fi rst 6 domains in all I/O cages are full and no Coupling link or PSC cards are required, the last domain in the I/O cage will be used for other I/O cards making a total of 28 per cage.
