IBM updates its mainframe processor to help AI

IBM has introduced a new CPU for its Z Series mainframe that’s designed for transactions like banking, training, insurance, customer interactions, and fraud detection.The Telum processor was unveiled at the annual Hot Chips conference and has been in development for three years to provide high-volume, real-time inferencing needed for artificial intelligence.The Telum design is very different from its System z15 predecessor. It features 8 CPU cores, on-chip workload accelerators, and 32MB of what IBM calls Level 2 semi-private cache. The L2 cache is called semi-private because it is used to build a shared virtual 256MB L3 connection between the cores on the chip. This is a 1.5x growth in cache size over the z15.To read this article in full, please click here

What is firewall as a service?

So what’s firewall as a service? Firewall as a service, or FWaaS, relies on technology in the cloud. A user or application connects to the FWaaS via the internet, and the service applies domain rules, URL filtering, and other security that physical firewall appliances use. The idea is to replace the multitude of hardware firewalls you’d need to secure all of your business’ traffic from all of its different operational sites with secure internet connections to the service.What’s wrong with firewall appliances? Possibly nothing. Physical firewalls are still quite popular, particularly for businesses without a lot of different locations and without a lot of remote workers. They even have some advantages over FWaaS, like different cost profiles. On-prem firewalls are a capex expenditure up-front but tend to be cheaper over time. They also have lower latency.To read this article in full, please click here

Private 5G: Tips on how to implement it, from enterprises that already have

We hear a lot about private 5G, meaning 5G networks deployed and owned by individual enterprises. A lot online, anyway; of 177 enterprises I've talked with this year, only three said they even knew how to build a private 5G network, and these three learned by doing it. The three discovered an important, but usually unrecognized, question, which is, “What do I it run on?” 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises One reason private 5G gets a lot of attention is that vendors have to talk about something, and one choice is to say something exciting and, well, maybe less than factual. The other is to say something factual and utterly uninteresting. Guess which gets said? The three enterprises that built private 5G networks had to educate themselves with a material from a variety of sources, including the O-RAN alliance, and one of the three characterized this as learning another language, with a dozen or Continue reading

Worth Listening: Heidi Roizen

Project AI+Compassion just interviewed Heidi Roizen about compassion in IT; it’s worth listening to. From the show notes—

Storytelling is a powerful way for humans to connect and for humans to move other humans to action. To understand your story and understand the stories of others, we can develop a lot more compassion for people when we understand that everybody has a story. Everybody story is important. So, don’t dismiss other people’s stories. Take the time to get to know everyone has a story.

Sharing Failure as a Learning Model

Earlier this week there was a great tweet from my friends over at Juniper Networks about mistakes we’ve made in networking:

It got some interactions with the community, which is always nice, but it got me to thinking about how we solve problems and learn from our mistakes. I feel that we’ve reached a point where we’re learning from the things we’ve screwed up but we’re not passing it along like we used to.

Write It Down For the Future

Part of the reason why I started my blog was to capture ideas that had been floating in my head for a while. Troubleshooting steps or perhaps even ideas that I wanted to make sure I didn’t forget down the line. All of it was important to capture for the sake of posterity. After all, if you didn’t write it down did it even happen?

Along the way I found that the posts that got significant traction on my site were the ones that involved Continue reading
