Optimizing Network Throughput on Azure M-series VMs
Tuning the network card interrupt configuration in Azure M-series VMs can substantially improve network throughput and lower CPU consumption. This blog discusses how to optimize Network Performance on Linux. The same concepts may also apply to Windows. SAP HCMT or other network test tools fail or produce lower than expected values.Optimize HANA deployments with Azure NetApp Files application volume group for SAP HANA
This article describes the value and use cases for Azure NetApp Files (ANF) volume provisioning using Azure NetApp Files application volume group (AVG) for SAP HANA. The article refers to a series of videos, which explain the pre-requisites as well as the different deployment scenarios in detail.SAP on Azure NetApp Files Sizing Best Practices
This article provides guidelines for properly sizing SAP deployments on Azure NetApp Files (ANF) to achieve optimal performance and cost-effectiveness. It emphasizes the importance of accurate capacity and performance estimation to avoid overprovisioning or underutilization of resources. The article introduces the "SAP on Azure NetApp Files Sizing Estimator" tool, which automates the sizing process and helps customers and partners to make informed decisions. By following these sizing guidelines and leveraging the tool, customers and partners can optimize their SAP landscapes on ANF for improved efficiency, reliability, and cost-effectiveness.SAP on Azure General Update – November 2020
Latest news, updates and certification updates for SAP on Azure. Updated SAP on Azure Documentation, Linux OMS Agent support for Python3, High LOGWRITE time for SQL TDE databases, Oracle Linux PTP, CLI for Python3, Suse License Key Issues and Azure Monitor for SAPUsing Azure NetApp Files AVG for SAP HANA to deploy HANA with multiple partitions (MP)
For larger HANA systems such as the new 24TiB VM's a single data volume does not deliver enough performance and capacity. For such a scenario SAP supports "Multiple partitions" (MP) where the SAP HANA database, stripes I/O across multiple data volumes. Application Volume Group (AVG) for SAP HANA optimizes the ANF volume deployment for SAP HANA for single data volumes but can also be tailored to deploy multiple data volumes.SAP on Azure General Update August 2022
Woolworths Australia goes live on Azure, new recommendations for SAP on Oracle direct from Oracle themselves. Disk Bursting and VM Bursting and new SSD v2 in preview. SQL Server 2022, ODBC 18 and Windows 2022 News for Windows customers and news for Linux customers Important guidance for sizing boot disks on Linux.Implementing Azure NetApp Files with Kerberos
Kerberos with ANF for SAP HANA Encryption is a very big topic when it comes to data security especially in public clouds. Azure NetApp Files (ANF) supports DES, Kerberos AES 128, and Kerberos AES 256 encryption types (from the least secure to the most secure). If you enable AES encryption, the user credentials used to join Active Directory must have the highest corresponding account option enabled that matches the capabilities enabled for your Active Directory.Architectural Decisions to maximize ANF investment in HANA N+M Scale-Out Architecture - Part 1
Do you have a large performance-sensitive SAP HANA footprint in Microsoft Azure? Are you looking to leverage SAP’s native resilience solution? Is operational flexibility at the top of your mind? If so, then look no further. This blog covers and answers the above-mentioned questions with Microsoft’s newer (since May 2019) PaaS storage service in partnership with NetApp, called Azure NetApp Files (ANF). In this blog series, I will focus on the technical execution aspects of running SAP HANA scale-out N+M on Azure NetApp Files from a Solution Architect’s point-of-view. More specifically, I will focus on how a solution architect would design, build, and operate the infrastructure, backup/recovery, and HA/DR components for a 2+1 scale-out scenario running on RHEL OS.Proximity Placement Groups in Azure : Testing the Impact on Query Performance in HANA
Hello All, I am into SAP Performance Optimization since many years and would like to share one of my case study about a performance issue on Azure. Sharing here for the benefit of other users in similar area. Network Latency in SAP Environments: Network latency is a very important metric to be measured, which has a direct impact on runtime of jobs or transactions run by users. Many SAP applications ( custom and standard ) run queries as part of application logic which requires multiple round-trips to database sometimes based on the program design. Examples could be a SELECT … UPTO 1 ROWS in a loop etc. A slight increase in latency can multiply as the number of times the loop is run and fetching records from database. During a migration of SAP to a IaaS or on-premise provider, it is difficult to identify these changes from an application level if the change is very insignificant per record, however it can multiply many fold if the logic is run in a loop. If the change is too big, it could be picked up my many metrics from Solman like increase in DB response time etc,so it can be identified easily. the detailed case study is published on SAP Blogs at https://blogs.sap.com/2020/09/23/proximity-placement-groups-in-azure-testing-the-impact-on-query-performance-in-hana/
