Understand Azure NetApp Files application volume group for SAP HANA

  • Статия

This article helps you understand the use cases and key features of Azure NetApp Files application volume group for SAP HANA.

Application volume group for SAP HANA enables you to deploy all volumes required to install and operate an SAP HANA database according to best practices. Instead of individually creating the required SAP HANA volumes (including data, log, shared, log-backup, and data-backup volumes), application volume group for SAP HANA creates these volumes in a single "atomic" call. The atomic call ensures that either all volumes or no volumes at all are created.

Application volume group for SAP HANA provides technical improvements to simplify and standardize the process to help you streamline volume deployments for SAP HANA. As a result, you can focus on your application demands instead of managing technical settings such as individual QoS or sizes for volumes.

Key features

Application volume group for SAP HANA is supported for all regions where Azure NetApp Files is available. It provides the following key features:

  • Supporting SAP HANA configurations for both single and multiple host setups, including:

    • Volumes for a single or primary SAP HANA database
    • Volumes for an SAP HANA System Replication (HSR) secondary system
    • Volumes for a disaster recovery (DR) scenario using cross-region replication

  • Creating the following volumes:

    • SAP HANA data volumes (one for each database host)
    • SAP HANA log volumes (one for each database host)
    • SAP HANA shared volumes (for the first SAP HANA host only)
    • Log-backup volumes (optional)
    • File-based data-backup volumes (optional)

  • Creating volumes in a manual QoS capacity pool. The volume size and the required performance (in MiB/s) are proposed based on user input for the memory size of the database.

  • The application volume group GUI and Azure Resource Manager (ARM) template provide best practices to simplify sizing management and volume creation. For example:

    • Proposing volume naming convention based on SAP System ID (SID) and volume type
    • Calculating the size and performance based on memory size

Application volume group for SAP HANA helps you simplify the deployment process and increase the storage performance for SAP HANA workloads. Some of the new features are as follows:

  • Use of proximity placement group (PPG) instead of manual pinning.

    • You anchor the SAP HANA VMs using a PPG to guaranty lowest possible latency. The PPG enforces the creation of data, log, and shared volumes in the close proximity to the SAP HANA VMs. See Best practices about Proximity Placement Groups for details.

  • Creation of separate storage endpoints (with different IP addresses) for data and log volumes.

    • This deployment method provides better performance and throughput for the SAP HANA database.

Extension 1 features (preview)

Application volume group for SAP HANA extension one offers support for:

  • Availability zone volume placement

    Designating the same availability zone for the volumes ensures that virtual machines and Azure NetApp Files volumes reside in the same availability zone and meet the latency requirements for SAP HANA. This improvement simplifies the deployment process, avoiding the manual AvSet pinning process and eliminating the requirement for availability sets.

  • Standard network features

    Application volume group for SAP HANA now supports selecting Standard network features for all volumes in the volume group. The availability of Standard network features simplifies deployment, avoiding the manual process for AvSet pinning and eliminating the need for availability sets.
