Hi Diego,
Your suggestion is much appreciated, and very much along my same line of thinking to look at Power11.
Our S924G's will soon reach the end of their standard maintenance, and extended support is so horrendously expensive that potentially the cost of a new Power11 is on a par with the extended support cost. No surprises there though.
We collect and monitor performance on a daily basis, with regular analysis, so no issue using the latest data to help size a new system. And if anything, we expect negative growth with a roadmap to migrate the application's functions (on IBM i) to other non-IBM i/Power systems. (Go figure :-( ) But it remains a critical business application with no clear end date for the migration. So we come back to the cost of extended support vs. upgrade. Totally agree - "...buy the most amazing machine you will never get from an Intel or AMD vendor :-)"
May have to resort to providing System Plans and current performance data to IBM or a Business Partner to size and quote a new system(s).
Thanks heaps Diego,

Hi Jozsef,
The workload estimator starts from a performance analysis on each LPAR, so you can get the real amount of resources you need.
Sometimes it is easier to get the same amount of CPUs, use the % of compute power increase as an improvement to your infrastructure, and add the % of memory based on compute power increase.
The drawback with this approach is, if you have more than enough resources today, you will buy and waste money on useless resources in a more expensive box than your actual system.
If you go on the 1st approach, using performance tools to get the amount of CPU, Memory and disk, you can read the IBM Power Performance Report and create your own chart comparing rPerf (AIX) or CPWs (IBM i)
My suggestion: Your system was GA in 2020 and withdrawn from marketing in 2023, S1024 was GA in 2024, so it is next to be EOM , so even when the S1124 or S1122 could look close in performance to the S1024, you could get more standard support years with the Power11 system.
Rule of thumb for Power9 to Power11 upgrade: you could get ~65% performance increase (could vary based on configuration and OS), and that could be even higher with new IBM Storage boxes.
Now, for consolidation:
- S924G can have up to 24 Power9 cores and was withdrawn from marketing in 2023.
- S1024 can have up to 48 Power10 cores and 4TB of memory and was launched in 2023.
- S1124 can add up to 60 Power11 Cores and 8TB of memory, a really amazing box and was launched this year.
- S1122 is similar to S1024, but IBM I LPARs with VIOS are limited to a maximum of 4 cores, but AIX LPARs are not limited.
Take a look at the Performance Report and compare compute power, add the X years growth you need, and buy the most amazing machine you will never get from an Intel or AMD vendor :-)

Hi Jozsef,
I am not sure, but I think this tool is withdrawn.
What do you need to do?

Subject: Where is the IBM Systems Workload Estimator
Hello,
I am having trouble locating the IBM Systems Workload Estimator, either web based or as a download.
When I try https://www.ibm.com/links?l=https%3A%2F%2Fwle.mybluemix.net%2Fwle%2FEstimatorServlet, it directs me to https://wle.mybluemix.net/wle/EstimatorServlet, which when I click that URL results in 504 DNS look up failed.
Is the IBM Systems Workload Estimator no longer available, and is there an alternative?
Thank you,
Jozsef
