IBM Is Running Out Of DDR4 Memory Faster Than It Thought

September 25, 2024 Timothy Prickett Morgan

Back in August, we told you about how Big Blue was shifting away from the DDR4 main memory chips and towards DDR5 main memory chips for Power10 systems, which were designed expressly to support both types of memory.

This is just like Power8 servers were designed to support both DDR3 and DDR4 memory, with the latter coming halfway through the Power8 product cycle. The Power9 machines used DDR4 memory solely, and the Power10 is getting support for DDR5 a little late in its cycle, given that we expect Power11 servers next year. Presumably the Power11 servers will just support DDR5 …

A Shot Across The Bow For Power8 Upgrades

November 29, 2021 Timothy Prickett Morgan

Sales of new Power8-based Power Systems machines by Big Blue have not been possible for years, but customers with existing Power8 iron have been able to get what IBM calls miscellaneous equipment specification, or MES, upgrades of their existing systems to add processing capacity to those vintage machines.

The Power8 lineup, launched in April 2014, and the entry machines in the Power8 lineup were withdrawn at the end of February in 2019, an announcement that IBM made in October 2018 to give customers fair warning. In February 2019, IBM said that it was going to withdraw high-end Power8 machinery …

Taking The Pulse Of The Used Server And Storage Market

February 3, 2021 Timothy Prickett Morgan

Those of us who buy certified pre-owned vehicles know a secret that some of our peers in the datacenter also know about buying certified pre-owned servers and storage: You can get a lot better bang for the buck by staying one generation behind, and not really sacrifice much in the way of performance and features.

And in the case of IT, unlike the situations with families buying vehicles, some customers have to stay two generations or more behind because of the limitations of their application software. And so they absolutely need to stay back on vintage iron. Even then, there …

Breathing New Life Into Your POWER7 And POWER7+ Systems

November 30, 2020 Timothy Prickett Morgan

This is a hard lesson for people to learn, but savvy IT organizations certainly do learn it – some decades ago, some only now. And that lesson is that not every application slowdown and performance bottleneck in a system is directly related to the clock speed or throughput of the central processor. While the processors are indeed central, a system is comprised of main memory, storage, and network I/O, and tuning up a machine as many times as not means bolstering these other components to help the CPU better do the job that is latent in its particular feeds and …
