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, the /hana/shared file system, which is used to store installation binary files, trace files, and so on.
Review the SAP HANA capacity requirements before allocating the pools, LUNs, or file systems in the Unity XT system.
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 relevant Unity XT technical documentation.
When creating a storage pool for the SAP HANA persistence, adhere to the following 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 UI to create storage pools. From the dashboard, select Storage > Pools, and then click the + sign.
