How Much Does NVM-Express Flash Really Boost IBM i Performance?

November 9, 2020 Timothy Prickett Morgan

With the NVM-Express protocol, a storage overlay for the PCI-Express peripheral bus that allows flash to be addressed in a parallel fashion as flash in its own right and not as emulated disk storage using a SATA or SCSI protocol, the idea is to get those vintage storage drivers out of the way and let the operating system kernel speak directly to the flash. This is done so the impressive – and seemingly always growing – I/O bandwidth of flash can actually be brought to bear to speed up applications.

Flash in general, and NVM-Express flash in particular, has been …

Tweaks To Power System Iron Complement TR Updates

October 12, 2020 Timothy Prickett Morgan

Back in July, IBM upgraded the peripheral I/O on several of its Power9-based servers with more PCI-Express 4.0 bandwidth capacity, and now IBM is offering the increased bandwidth on several machines tuned up for running SAP HANA in addition to making a number of other hardware enhancements and withdrawals.

In announcement letter 120-054 you will get the feeds and speeds of the updated Power H922, a two-socket, 2U server, and in announcement letter 120-055 you will get the feeds and speeds of the updated Power H924, a two-socket, 4U system. As far as I can tell, the machines are essentially …

IBM Revamps Entry Power Servers With Expanded I/O, Utility Pricing

July 14, 2020 Timothy Prickett Morgan

Believe it or not, but it has been two and a half years since the first Power9 server shipped and it has been more than two years since the entry Power Systems machines – that would be the Power S914, the Power S922, and the Power S924 machines, code-named “ZZ” after the country-rock-blues band from Houston – were first announced. And today, these machines are getting an I/O makeover.

And specially for IBM i shops, IBM is rolling out a single-core version of the Power S922 that will offer better bang for the buck as well as lower acquisition cost …

The Skinny On NVM-Express Flash And IBM i

November 4, 2019 Timothy Prickett Morgan

A couple of weeks ago, buried in the October Power Systems announcements, we told you about the new NVM-Express flash cards that Big Blue brought to the Power iron and that are specifically enabled in the IBM i 7.4 release with Technology Refresh 1, or TR1. We didn’t have a lot of detail back then about the new drives other than some capacities and pricing, but we know more now and we are going to tell you what we know.

We will circle back with Big Blue and have a discussion about what the addition of NVM-Express flash means – …

Power Systems Refreshes Flash Drives, Promises NVM-Express For IBM i

April 29, 2019 Timothy Prickett Morgan

There was a time after Mark Olsen retired a few years back when the presentations concerning Power Systems hardware as it related to the IBM i platform were not as detailed as we were used to. But a new team of people are running the show now, and they are getting better and that helps us all understand what Big Blue is doing on the hardware front even better.

As part of the April 23 announcements, IBM added a bunch of new storage and networking peripherals to its Power8 and Power9 system lineup. You can read all about it in …

Melding System Monitoring And Capacity Planning

April 24, 2019 Timothy Prickett Morgan

(Sponsored Content) Installing a modern system to run enterprise applications is a pretty tough task, but the job is not done once the iron is in and the databases and applications are up and running. Sophisticated organizations, whether they are large or small, do sophisticated application and system monitoring to keep an eye on how things are running, they have job schedulers that synchronize work to optimize for performance as well as drive up system utilization, and they use all of the information gathered to better plan for the kinds of systems they will need in the future …

2019 Predictions: IBM i Trend Spotting

January 23, 2019 Alex Woodie

What will happen in the IBM i community this year? Maybe IBM will launch a public cloud service? Or IBM i shops will find the budget to get busy with application modernization? It’s really anybody’s guess, which is why IT Jungle solicited predictions from prominent names in the community to get their take on what will happen this year.

The wider IT community is moving quickly to adopt next-gen development methodologies, and those will increasingly find their way into the IBM i community in 2019, predicts Dan Magid, vice president of solution sales with Rocket Software.

“2019 will bring …

IBM Expands Flash Drives For Power8 Iron

November 27, 2017 Timothy Prickett Morgan

Back in October, IBM announced a new lineup of small form factor disk drives with 1.8-inch and 2.5-inch form factors as well as updates for 2.5-inch flash drives that were a little bit on the beefy size. We suspect that these drives were intended to be co-launched with Power9-based servers, as well as some new, skinnier flash drives that were announced just before the Thanksgiving holiday in the United States.

On November 21, in announcement letter 117-108, Big Blue rolled out the new 2.5-inch flash drives that are based on 3D NAND flash memory and are rated at …

More Power7 And Power8 Features To Bite The Rust

October 30, 2017 Timothy Prickett Morgan

The Power Systems catalog just keeps getting skinnier as the Power9 systems launch in early 2018 keeps getting closer. Ironically, as IBM pulls the plug on older Power Systems machines and their features, it is a good indication that Big Blue really is preparing the way for Power9. It is also a way to get customers who have no intention of spending on Power9 iron to buy something on their older gear before the features go away.

I saw a new abbreviation in announcement letter 917-177, which came out on October 24, and that was LTB – short for …
