All Unity XT arrays are available as all-flash models (F models) and hybrid models. Both model types can be used for SAP HANA. However, the capacity that is used for the SAP HANA persistence (data and log) must be allocated on storage pools with SSDs only and a single tier must be configured (no FAST VP and no FAST cache). HDDs on the hybrid models can be used for other SAP HANA capacity, that is, the /hana/shared file system, which is used to store installation binaries, trace files, and so on.
Before allocating the pools, LUNs, or file systems in the Unity XT, ensure that you review the SAP HANA capacity requirements.
Note: The following configuration recommendations for pools, LUNs, and file systems apply only to the SAP HANA persistence.
The Unity XT models use unified storage pools, which can source block LUNs, NAS file systems, and VMware Virtual Volumes. The pools can be dynamic pools or traditional pools. Traditional pools are available in both Unity XT hybrid and all-flash models while dynamic pools are available only in all-flash models. Some restrictions apply to the different pool types, but both types can be used for the SAP HANA persistence. For more information, see the Unity XT technical documentation.
When creating a storage pool for the SAP HANA persistence, adhere to these configuration guidelines:
Note: The number and size of the disks in the pool may depend on the overall SAP HANA capacity requirements.
Use the Unity XT Unisphere user interface (UI) to create storage pools. From the dashboard, select Storage > Pools, and then click the + sign.
