Each of our z16s required 10 copper connections spread across 2 separate LANs / switches.
A1: Our z16s came with 2 HMAs (Hardware Management Appliance) in each z16, each redundantly takes care of the SE and HMC functions. As before there are two separate SEs, and now there are two HMCs for each z16. No cabling was required for connectivity between HMC and SE functions in a single HMA. A2: Each of our z16s has 10 copper network connections. Two for each of the HMCs (4 total), two for each of the SEs (4 total), and two additional for ETS ports assuming you are using an external time server. These ports are not in either of the HMAs, they are totally separate. Note that this functions used to be in the HMCs. I have a diagram I got from IBM that shows these 10 connections on the z16 and which network they get plugged into. A3: We can see all of our z16s from all of our HMCs, even though they ae spread across multiple sites. One of each of the HMC connections is to your intranet, and the IBM SSR made the definitions in the HMCs. Tom Chicklon Fifth Third Bank From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Radoslaw Skorupka Sent: Wednesday, December 18, 2024 12:27 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: z16 HMC LAN connections Good news: I'll be installing new z16 machines. :-) There is no longer physical HMC! Physically we have two x86 "pizza box" machines inside CPC cabinet, one is primary SE, the second is Secondary SE. And HMC as an virtual machine. To be precise HMC is an application working on machine's OS, while SE runs in guest machine. What about LAN ports? Q1. Connectivity between SE and HMC. Is it physical connection or some emulated internal LAN, more or less like Hipersockets? Q2. How to know what physical LAN port belongs to SE or HMC? Q3. How to connect SEs from two machines to create single logical network (both CPCs can be managed from single HMC)? I know how the things look like in case of old physical HMC, but virtual HMC changes physical connectivity. Any clue? Presentation? (yes, I have documentation) -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu<mailto:lists...@listserv.ua.edu> with the message: INFO IBM-MAIN This e-mail transmission contains information that is confidential and may be privileged.
