IBM upgrades Linux mainframe, boosting availability and AI efficiency


Had been you unable to attend Remodel 2022? Take a look at the entire summit classes in our on-demand library now! Watch right here.

The mainframe, the {hardware} stalwart that has existed for many years, is constant to be a pressure for the fashionable period.

Among the many distributors that also construct mainframes is IBM, which at present introduced the most recent iteration of its Linux-focused mainframe system dubbed the LinuxOne Emperor 4. IBM has been constructing LinuxOne techniques since 2015, when the primary Emperor mainframe made its debut, and has been updating the platform on a roughly two-year cadence.

The LinuxOne Emperor 4 is predicated on the IBM z16 mainframe that was introduced by IBM in April. Whereas the z16 is optimized for IBM’s z/OS working system, the LinuxOne, not surprisingly, is all about Linux and to a big extent the Kubernetes cloud-native platform for container orchestration as nicely.

“It solely runs Linux and it’s actually meant to fulfill the wants of the individuals who run Linux-based infrastructure within the knowledge facilities by offering them a brand new paradigm round find out how to drive a Linux atmosphere that’s extra environment friendly and extra scalable,” Marcel Mitran, IBM Fellow, CTO of cloud platform, IBM LinuxONE, instructed VentureBeat.

IBM continues to construct out non-x86 {hardware} for enterprises

The LinuxOne is a part of IBM’s general {hardware} portfolio, which is aggressive in opposition to different silicon architectures, most notably x86, which is developed by Intel and AMD.

IBM additionally builds the Energy-based structure, which additionally will be optimized for Linux deployments. In July, IBM introduced a new lineup of Power10 servers for enterprise use circumstances. Throughout its mainframe and Energy techniques portfolio, IBM reported income progress in its most up-to-date monetary quarter with mainframe revenues up by 69%.

Mainframes and, specifically, the LinuxOne are persevering with to search out adoption inside monetary providers organizations around the globe. Amongst IBM’s LinuxOne customers is Citibank, which makes use of the mainframe system alongside the MongoDB database to energy a few of its mission-critical monetary providers.

Contained in the LinuxOne Emperor 4

The brand new LinuxOne Emperor 4 system helps 32 IBM Telum processors, that are constructed on a 7 nm course of. The system offers as much as 40 TB of RAIM (Redundant Array of Impartial Reminiscence) and has been designed with quantum-safe cryptographic algorithms to assist present a excessive diploma of safety.

Picture supply: IBM.

Mitran famous that the LinuxOne Emperor 4 offers “seven nines” of availability (99.99999), which interprets into solely three seconds of downtime in a yr.

The excessive availability is enabled by numerous progressive applied sciences together with the usage of self-healing RAIM reminiscence. Mitran stated that the brand new system additionally has a function that can allow a system core to failover to an accessible core when wanted, straight away.

“There’s built-in expertise to do knowledge middle failover, each from a compute and storage perspective, utilizing new expertise known as GDPS [Geographically Dispersed Parallel Sysplex] hyperswap expertise,” Mitran stated. “That and a lot extra of what’s engineered into these techniques is how we ship on the design for seven nines of availability.”

AI inference match for an emperor

Among the many new capabilities within the LinuxOne Emperor 4 is built-in synthetic intelligence (AI) inference that’s embedded on the {hardware} layer.

AI inference is the a part of the method that makes a prediction or a choice. Mitran stated that the built-in inference with LinuxOne Emperor 4 allows the inferencing to be performed as a part of a transaction. With out the mixing, inference is completed in a separate course of, which may enhance latency. 

One frequent use case the place built-in inference may assistance is with fraud detection, which may now be performed faster, with out unnecessarily delaying a transaction.

“By having the AI accelerator on the chip, making it extraordinarily quick, we’re capable of now run the inferencing as a part of transactional workloads,” Mitran stated.
