A few days ago I wrote about the Open Mainframe Summit 2023, which took place on community day of the IBM TechXchange conference, but I also had the rest of that conference to enjoy!
The first week I was with IBM I went to IBM TechU. Given the technical nature, the new IBM TechXchange conference feels like the spiritual successor to this event, so I was really happy to have the opportunity to attend this inaugural event. I will start out by saying it was personally a real pleasure to finally meet so many people I’ve worked with over the years in person, so it was a bit of a selfie extravaganza!
Naturally, after the event you realize how many people you didn’t get photos with, especially and paradoxically, if you spent a lot of time together! Next time, my friends.
To set the stage for the week I attended a few keynotes here and there. The first was In a world where AI writes code, what is the role of the developer? following much over-hyped discourse around the obsolesce of developers if AI is writing code. It has long struck me as an odd position to take, so it was nice to see IBM pushing hard against it and stressing how importance it is to have humans in the mix who can focus on the problems that computers simply can’t solve. We still get all the interesting work, and there will always be more of it. I’m looking forward to using AI-infused tools to help me write Ansible playbooks for scenarios that I’m not fully familiar with the syntax of yet.
The thing about the keynotes is that they’re recorded, so I could go back and watch them later. Since there were regular, unrecorded sessions happening during the keynotes, I generally preferred to take advantage of my on-site presence there to attend those instead. Since this was my first time at this event and it had been quite some time since I’d been to an IBM-focused event, I decided to focus on my particular area of interest, IBM Z and LinuxONE, rather than branching too much out into other sessions around Power or Quantum. Part of my role at this event was also as a room moderator, so there were several sessions that I was required to be at, thankfully the colleague who was assigning the room monitoring duty was aware of our interests and they were sessions I wanted to be in anyway.
Of particular note, were the sessions about the rack-mount IBM z16, and there were a pair of sessions that dove deep into this. The first was Explore IBM Z’s first-ever rack mount options for IBM z16 and IBM LinuxONE by the legendary Kenny Stine. It was a real pleasure to meet Kenny after years of me begging him for technical review and early access to IBM Z internals photos so I could prepare my technical “tour” blog posts that I publish on IBM Developer. Given that I’m already pretty deep into the technical territory here, including a blog post on the topic, I knew what I was getting into when I joined his session, but I always leave these with a few more tidbits than I knew before. In Kenny’s talk I really benefited from the historical perspective that he brought to the discussion as he was comparing the systems over time and explaining just how different the IBM z16 with the IBM Telum chip is from its predecessors.
Bonus, he had a Telum chip with him that he passed around the audience. It was my first time getting to hold one!
The other talk of note on this topic was Interactive Step-by-Step Planning for new rack mount format for IBM z16 and LinuxONE 4. This session featured hands-on experience from Jim Fyffe of Evolving Solutions, Inc. where they received a rack-mount z16 and shared the unboxing, installation, and general impressions of putting it into production. I listened to an IBM z/Action! podcast that he was on back in July, but I loved this presentation because it had photos of their installation process! And a lot more details than the 20 minute podcast. Plus, I learned about the IBM z16 Rack Mount Bundle (3932-AGZ) section of the documentation that has lots of cool documents around installation, port planning, and cabling best practices. I’m not even being sarcastic, I used to work in data centers and this stuff is pure gold when you’re planning a setup.
I went to several sessions around implementation of a hybrid cloud design, with the mainframe remaining a key component of the infrastructure while bringing in cloud-based services, and Kubernetes. One of the last sessions I went to of the entire event was even focused on breaking up the monolith, and clarity around the journey you’re about to embark on if you’re migrating very old systems that still work.
I was also invited to participate in an open source on IBM Z panel on Tuesday afternoon, “From Ansible to Zowe: Opening the mainframe for a modern, scalable, inclusive & secure enterprise.” Due to shifting travel schedules, the panelist lineup was shuffled up a bit last minute, so I was a late addition and we only had a single sync up call prior to the panel. Thankfully, Joe Winchester was a great moderator, all of us panelists seemed to work quite naturally together, and we had a thoughtful and engaging audience.
The event featured a “Sandbox” which was basically an Expo Hall where IBM, partners, and related organizations showed off their latest featured products. It was particularly fun for me though because I finally got to “meet” the life-size IBM z16 LEGO model! Since I first learned about it via Think 2023, I’ve been quite enamored with it and I even took some time to interview the masterminds behind it for a blog post on IBM community: All about the life-size IBM z16 LEGO® brick model!.
I even got my wish granted to flip the colors to “orange” so it was effectively an IBM LinuxONE (sans badge, bummer!).
It was also technically the first time I got to see an IBM z16 in person. I haven’t been traveling as much this year, so I haven’t made it to a client center or otherwise to see one, with the proper doors. This was the plexiglass version though, which has all the fun lights that allow you to see the internals.
It was the first event I’d been to since 2020 that lasted more than a couple days, so I received a fast refresher in what these longer conferences are like: tiring and inspiring! I walked away with a lot of notes based on conversations I had with people that inspired ideas and plans. Once this year’s IBM Z Day extravaganza is behind us and I have some breathing room, it’ll be great to get to work on those ideas.
