IBM Fires a Shot at Intel with its Latest POWER Roadmap

June 17, 2016

In case you worry that IBM will abandon hardware in the pursuit of its strategic initiatives focusing on cloud, mobile, analytics and more; well, stop worrying. With the announcement of its POWER Roadmap at the OpenPOWER Summit earlier this spring, it appears POWER will be around for years to come. But IBM is not abandoning the strategic initiatives either; the new Roadmap promises to support new types of workloads, such as real time analytics, Linux, hyperscale data centers, and more along with support for the current POWER workloads.

Specifically, IBM is offering a denser roadmap, not tied to technology and not even tied solely to IBM. It draws on innovations from a handful of the members of the Open POWER Foundation as well as support from Google. The new roadmap also signals IBM’s intention to make a serious run at Intel’s near monopoly on enterprise server processors by offering comparable or better price, performance, and features.

Google, for example, reports porting many of its popular web services to run on Power systems; its toolchain has been updated to output code for x86, ARM, or Power architectures with the flip of a configuration flag. Google, which strives to be everything to everybody, now has a highly viable alternative to Intel in terms of performance and price with POWER. At the OpenPOWER Summit early in the spring, Google made it clear it plans to build scale-out server solutions based on OpenPower.

Don’t even think, however, that Google is abandoning Intel. The majority of its systems are Intel-oriented. Still, POWER and the OpenPOWER community will provide a directly competitive processing alternative.  To underscore the situation Google and Rackspace announced they were working together on Power9 server blueprints for the Open Compute Project, designs that reportedly are compatible with the 48V Open Compute racks Google and Facebook, another hyperscale data center, already are working on.

Google represents another proof point that OpenPOWER is ready for hyperscale data centers. DancingDinosaur, however, really is interested most in what is coming from OpenPOWER that is new and sexy for enterprise data centers, since most DancingDinosaur readers are focused on the enterprise data center. Of course, they still need ever better performance and scalability too. In that regard OpenPOWER has much for them in the works.

For starters, POWER8 is currently delivered as a 12-core, 22nm processor. POWER9, expected in 2017, will be delivered as 14nm processor with 24 cores and CAPI and NVlink accelerators. That is sure to deliver more performance with greater energy efficiency.  By 2018, the IBM roadmap shows POWER8/9 as a 10nm, maybe even 7nm, processor, based on the existing micro-architecture.

The real POWER future, arriving around 2020, will feature a new micro-architecture, sport new features and functions, and bring new technology. Expect much, if not almost all, of the new functions to come from various OpenPOWER Foundation partners,

POWER9, only a year or so out, promises a wealth of improvements in speeds and feeds. Although intended to serve the traditional Power Server market, it also is expanding its analytics capabilities and bringing new deployment models for hyperscale, cloud, and technical computing through scale out deployment. This will include deployment in both clustered or multiple formats. It will feature a shorter pipeline, improved branch execution, and low latency on the die cache as well as PCI gen 4.

Expect a 3x bandwidth improvement with POWER9 over POWER8 and a 33% speed increase. POWER9 also will continue to speed hardware acceleration and support next gen NVlink, improved coherency, enhance CAPI, and introduce a 25 GPS high speed link. Although the 2-socket chip will remain, IBM suggests larger socket counts are coming. It will need that to compete with Intel.

As a data center manager, will a POWER9 machine change your data center dynamics?  Maybe, you decide: a dual-socket Power9 server with 32 DDR4 memory slots, two NVlink slots, three PCIe gen-4 x16 slots, and a total 44 core count. That’s a lot of computing power in one rack.

Now IBM just has to crank out similar advances for the next z System (a z14 maybe?) through the Open Mainframe Project.

Ubuntu Linux (beta) for the z System is Available Now

April 8, 2016

As recently as February, DancingDinosaur has been lauding IBM’s bolstering of the z System for Linux and support for the latest styles of app dev. As part of that it expected Ubuntu Linux for z by the summer. It arrived early.  You can download it for LinuxONE and the z now, hereubuntu-logo-300x225

Of course, the z has run Linux for over a decade. That was a customized version that required a couple of extra steps, mainly recompiling, if x86 Linux apps were to run seamlessly. This time Canonical and the Ubuntu community have committed to work with IBM to ensure that Ubuntu works seamlessly with IBM LinuxONE, z Systems, and Power Systems. The goal is to enable IBM’s enterprise platforms to play nicely with the latest app dev goodies, including NFV, containers, KVM, OpenStack, big data analytics, DevOps, and even IoT. To that end, all three parties (Canonical, the Ubuntu community, and IBM) commit to provide reference architectures, supported solutions, and cloud offerings, now and in the future.

Ubuntu is emerging as the platform of choice for organizations running scale-out, next-generation workloads in the cloud. According to Canonical, Ubuntu dominates public cloud guest volume and production OpenStack deployments with up to 70% market share. Global brands running Ubuntu at scale in the cloud include AT&T, Walmart, Deutsche Telecom, Bloomberg, Cisco and others.

The z and LinuxONE machines play right into this. They can support thousands of Linux images with no-fail high availability, security, and performance. When POWER 9 processors come to market it gets even better. At a recent OpenPOWER gathering the POWER 9 generated tremendous buzz with Google discussing its intentions of building a new data center server  based on an open POWER9 design that conforms to Facebook’s Open Compute Project server.

These systems will be aimed initially at hyperscale data centers. OpenPOWER processors combined with acceleration technology have the potential to fundamentally change server and data center design today and into the future.  OpenPOWER provides a great platform for the speed and flexibility needs of hyperscale operators as they demand ever-increasing levels of scalability.

According to Aaron Sullivan, Open Compute Project Incubation Committee Member and Distinguished Engineer at Rackspace. “OpenPOWER provides a great platform for the speed and flexibility needs of hyperscale operators as they demand ever-increasing levels of scalability.” This is true today and with POWER9, a reportedly 14nm processor coming around 2017, it will be even more so then. This particular roadmap looks out to 2020 when POWER10, a 10nm processor, is expected with the task of delivering extreme analytics optimization.

But for now, what is available for the z isn’t exactly chopped liver. Ubuntu is delivering scale-out capabilities for the latest development approaches to run on the z and LinuxONE. As Canonical promises: Ubuntu offers the best of open source for IBM’s enterprise customers along with unprecedented performance, security and resiliency. The latest Ubuntu version, Ubuntu 16.04 LTS, is in beta and available to all IBM LinuxOne and z Systems customers. See the link above. Currently SUSE and Red Hat are the leading Linux distributions among z data centers. SUSE also just announced a new distro of openSUSE Linux for the z to be called openSUSE Factory.

Also this week the OpenPOWER Foundation held its annual meeting where it introduced technology to boost data center infrastructures with more choices, essentially allowing increased data workloads and analytics to drive better business results. Am hoping that the Open Mainframe Project will emulate the Open POWER group and in a year or two by starting to introducing technology to boost mainframe computing along the same lines.

For instance OpenPOWER introduced more than 10 new OpenPOWER servers, offering expanded services for high performance computing and server virtualization. Or this: IBM, in collaboration with NVIDIA and Wistron, revealed plans to release its second-generation OpenPOWER high performance computing server, which includes support for the NVIDIA Tesla Accelerated Computing platform. The server will leverage POWER8 processors connected directly to the new NVIDIA Tesla P100 GPU accelerators via the NVIDIA NVLink, a high-speed interconnect technology.

In the same batch of announcements TYAN announced its GT75-BP012, a 1U, POWER8-based server solution with the ppc64 architecture. The ppc64 architecture is optimized for 64-bit big-endian PowerPC and Power Architecture processors.  Also of interest to DancingDinosaur readers may be the variation of the ppc64 that enables a pure little-endian mode with the POWER8 to enable the porting of x86 Linux-based software with minimal effort. BTW, the OpenPOWER-based platform, reportedly, offers exceptional capability for in-memory computing in a 1U implementation, part of the overall trend toward smaller, denser, and more efficient systems. The latest TYAN offerings will only drive more of it.
