Architect SAP on Azure


HANA Sizing

SAP HANA sizing

  • SAP HANA has some very specific requirements regarding CPU, memory, networking, and storage

  • For green field implementations, SAP Quick Sizer is available to calculate memory requirements of the implementation of SAP software on top of HANA

  • Consider more cost-optimized solutions for at least some of your non-production

CPU and memory requirements

  • SAP HANA database sizing is primarily focused on the amount of memory required

  • Based on the required memory, customers can choose a certified platform to run the database workload in Azure

SAP-certified Azure HANA large instances

  • VMs with up to 6 TB of memory imminently, and availability of VMs with 12 TB of memory 

  • Bare-metal Azure HANA Large instances using Intel Optane memory, including a 4-socket 9 TB instance and an 8-socket 18 TB instance

Network requirements

Client Zone:

Connects to database including the HTTP communication when using the SAP HANA XS engine


Internal Zone:

Internal communication between SAP HANA instances, for example in a System Replication scenario or in Scale-Out deployment

Storage Zone:

For accessing data and log files that are stored on SAN or NAS

The recommended configurations with Azure premium storage for production

Configuration for SAP /hana/data volume

Storage layout for virtual machines using Ultra SSDs

Storage requirements

For HANA VMs, you must build the SAP HANA storage configuration manually based on the four disk types available in Azure

Standard HDD:

A storage solution based on HDD disks, should not be used with SAP HANA

Standard SSD:

SSD disks, offers similar throughput as the Standard HDD storage, but improves the data access latency.

Not used for production HANA instances

Premium SSD:

A solution based on high performance SSD, and the recommended storage for M series and Mv2 series VMs when used for SAP HANA and combined with the Write Accelerator

Ultra SSD:

A solution based on ultra performance SSD, the only supported storage for Ev3 series VMs, and gradually being supported on M series and Mv2 series
