News for AWS, GCP and MS Azure

🎯 GCP has certified the first Emerald Rapids SP instances - c4-highmem (2024-08-14)
🎯 MS Azure has certified Msv3 + Mdsv3-series with max. 1792 vCPUs and 30TB RAM (2024-09-02)
🥇 AWS is the leader in the virtualized instance type category
🥇 GCP is the leader in the bare metal instance type category

total by RAM statistic:
1. GCP : x4-megamem-1920-metal: 32.768 GiB
2. MS Azure: M896ixds_32_v3 / M1792ixds_32_v3: 30.400GiB
3. AWS: u7in-24tb.224xlarge: 24.576GiB

🌇 As MS Azure's S-Series (HANA Large Instance service) is in sunset mode, there are no bare metal instances left which you can order.

HANA OS maintenance
von Jens Gleichmann 27 Sept., 2024
Please notice that when you want to run HANA 2.0 SPS07, you need defined OS levels. As you can see RHEL7 and SLES12 are not certified for SPS07. The SPS07 release of HANA is the basis for the S/4HANA release 2023 which is my recommended go-to release for the next years. Keep in mind that you have to go to SPS07 when you are running SPS06 because it will run out of maintenance end of 2023.

RISE with SAP: Roles & Responsibilities
von Jens Gleichmann 24 Mai, 2024
For every possible RISE with SAP customer it is essential to know the difference of the status quo system construct (on-prem self managed / hosted or managed by a MSP) and the RISE offering with a lot of excluded tasks or tasks with additional costs. If you don't need this tasks, it might be a perfect solution, but our experience is that most customers need some of the services with extra costs.
Performance degradation after upgrade to SPS07
von Jens Gleichmann 29 Apr., 2024
With SPS06 and even stronger in SPS07 the HEX engine was pushed to be used more often. This results on the one hand side in easy scenario to perfect results with lower memory and CPU consumption ending up in faster response times. But in scenarios with FAE (for all entries) together with FDA (fast data access), it can result in bad performance. After some customers upgraded their first systems to SPS07 I recommended to wait for Rev. 73/74. But some started early with Rev. 71/72 and we had to troubleshoot many statement. If you have similar performance issues after the upgrade to SPS07 feel free to contact us! Our current recommendation is to use Rev. 74 with some workarounds. The performance degradation is extreme in systems like EWM and BW with high analytical workload.

SUM tooling with target HANA
von Jens Gleichmann 18 März, 2024
Numerous IT projects such as S/4HANA projects or HANA migrations will go live over the Easter weekend. Mostly this tasks will be controlled by the SAP provided SUM tool. The SUM is responsible for the techn. migration/conversion part of the data. Over the past years it become very stable and as long as you face no new issues nearly every technical oriented employee at SAP basis team can successfully migrate also bigger systems. In former times you needed a migrateur with certification which is no longer required. As long as all data could be migrated and the system is up and running the project was successful. But what does the result look like? Is it configured according to the best recommendation and experience? Is it running optimized and tuned?No, this is where the problem begins for most companies. The definition of the project milestone is not orienting on KPIs. It is simply based on the last dialog of the SUM tool, which states that the downtime has ended and all tasks have been executed successfully.
Abstract SQL Plans
von Jens Gleichmann 13 Dez., 2023
The feature plan stability is not a new one, but can help you in case of an revision update/upgrade, if you recognize big performance degradations. But you have to activate this feature at least 1-2 weeks before the maintenance to capture the SQLs and the execution plan. You can compare the plan performance and apply the execution plan with the best performance. You can also use it as always on feature in daily operations. This may be required due to changes in data over time which may cause the query optimizer to propose different execution plans which may have a negative impact on performance and memory consumption of a query. An additional preparation step can be used to apply filters so that only specific queries are captured. In the background execution statistics are recorded so that the performance of the query can be measured and the best execution plan can
