Inside The IBM “Denali” Power E1080 System

November 8, 2021 Timothy Prickett Morgan

With Big Blue not really shipping its Power10-based big, bad “Denali” Power E1080 system in full volume and with full configurations until December, we knew we would have some time to dig down into the architecture of the Denali systems. And with other things out of the way, which also needed to be covered, including our initial coverage on the Power E1080 machine on September 8 and some follow-on stories, we are now eagerly taking the lid off the Denali machine and taking a hard look at it for you.

Seriously. Here is the machine with the lid off of …

Power9 Prime Previews Future Power10 Memory Boost

September 30, 2019 Timothy Prickett Morgan

Customers who are deploying Linux on Power Systems iron from Big Blue are about to get a very substantial boost in memory bandwidth as IBM is getting ready to launch the Power9’ (that’s a prime symbol, not an apostrophe or a typo, after the 9) processor. As we previewed back in March 2018, the Power9’ chip will feature a substantially upgraded memory subsystem that has a new, faster SERDES signaling technology, normally used for various kinds of system and accelerator interconnect, that has been tweaked to support memory buffers and therefore DDR4 and future memories.

There is no technical …

Power Systems Not Getting 3D XPoint Memory Anytime Soon

April 1, 2019 Timothy Prickett Morgan

A lot of people don’t remember this, but Intel was founded in 1968 as a maker of semiconductor main memory for mainframes, and in the early 1970s the company commanded almost as much market share in main memory as it does in datacenter compute today. But as competitors in Japan did a better job ramping up new technologies, by the early 1980s Intel’s market share dropped to somewhere between 2 percent and 3 percent, and it had no way to easily or affordably get back into the game, and by 1984 it had to wind down its memory operations. …

I Dare You To Keep Track Of Power Systems Memory Prices

November 5, 2018 Timothy Prickett Morgan

One of the great things about IBM is that, thanks to a series of antitrust lawsuits that it settled with the U.S. Department of Justice’s Antitrust Division – after much, much legal grief and heaven only knows how much expense – back in the 1960s and 1980s, the company has created systems that tell customers about its products, how they change an evolve, and what they cost at any given time.

All vendors should be required by law to publish list prices, because they provide a ceiling to the negotiations. A point above which you know a vendor is not …

IBM Readies Big Iron With “Cumulus” Power9 Chips

July 30, 2018 Timothy Prickett Morgan

The Power Systems lineup has been updated top to bottom on single-socket and dual-socket machinery based on the “Nimbus” variants of the Power9 chip, which sport up to 24 cores per die and have up to four threads per core. These Nimbus chips are used in all kinds of machines, including those that can run IBM i, either alongside AIX or Linux using the PowerVM hypervisor or in what is made to look like a bare metal IBM i setup but which is really a PowerVM machine with one partition. (Shhhhh.) The Nimbus processors are also deployed in …

IBM Hikes Memory Prices On Power8 And Power9 Iron

June 11, 2018 Timothy Prickett Morgan

It is a problem that all server makers are facing: Raw DRAM and flash memory prices have been rising for the past year and a half, yet they are loath to raise their own prices because such rude spikes will actually curtail demand for servers given the sizes of the slices of the server cost pie that main memory and now flash memory comprise. When memory prices started rising at the end of 2016, most people thought it would not last for more than a few quarters, but the DRAM and flash makers are happy to make more dough doing …
