The YouTube is excellent in promoting key strengths of z in a light hearted manner. With numerours z systems on the test floor during development, testing and product and stress testing the patch panel is key to enable 'any to any' configurations.

Thanks to youtube, the first IBM z I've seen was the z16 tour at https://youtu.be/ZDtaanCENbc. You say 192 slots or 384 ports. I understand slots being PCIe but was is ports? Is this fiber optic cables or does it somehow split a PCIe slot? > I've had to untangle some 150+ cable rats nests, but> for that one I'd just > say, Naw... I'm going home :) Towards the end of the video, they show the patch panels which are true rats nests. Looks like some of the network rooms I've seen. Some people don't mind dealing with a mess. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
