I just ran a test config for a full z16 A01 and it had the limits I mentioned. I am impressed! For the past few years upgrades have generally gone from 2 cables to 4 cables which can be a surprise for the facilities folks. I can't even comprehend 8 x 32 = 256 14 foot cables. A couple of

Kevin’s note is a great summary. FWIW, years ago when I worked for IBM (early 2000’s) we met with RedHat. During the introductions someone from IBM referred to them as an Open Source company. One of the RedHat execs corrected them and said, “We are a commercial software company that uses

Let me try to respond to some of this; keeping in mind that I know nothing of the business decisions here, and am speaking for myself, not IBM. 1. As far as I’m aware, IBM is still very separate from RedHat. Maybe things are different at the board level, but at my level, there is an

Re: Will z/OS be obsolete in 5 years?

z\OS containers being crucial? Absolutely. Some z\OS, DB/2, etc. upgrades require applications, subsystems, LPARs, Sysplexes, etc. At a certain stage before proceeding to the next stage. Hopefully these requirements can be limited to one or a small subset of containers. On Wed, Jul 19, 2023,

Yes, it is, because quantum computing enables solving classes of problems that current machines can't. But it is a very poor fit for the overwhelming majority of computing tasks today. Put another way: a z/Series vector facility isn't going to do much good computing payroll. Neither is a quantum

The "gift" is not containers but container tech... layering. Just lifting and shifting distributed tech onto mainframe, with no consideration of the extreme complexities is very wasteful. Container orchestration exists because some of those containers (or the hosts they may run on) may have a

Here's a dumb and bold prediction - the guts of RHEL (CoreOS) will be laid bare within zOS. USS becomes LSS. zOS native containers are actually normal containers that you see in the linux world. DSFS and zCX end up helping to blur the boundaries between zOS and LSS. zOS is not going away. But we
