The Unity XT family has been certified for SAP HANA using the SAP HANA-HWC-ES-1.1 certification scenario. For more information, see the Certified and Supported SAP HANA Hardware Directory.
Both all-flash and hybrid Unity XT models can be used for SAP HANA. With hybrid models, however, the storage pool for the SAP HANA persistence (data and log) must reside on a single tier consisting of flash disks.
Customers can now choose between two connectivity protocols for the SAP HANA nodes: FC and NAS (NFS). Both these connectivity protocols have been certified for SAP HANA. For information about the host and network requirements for these protocols, see Network design considerations.
For an SAP HANA TDI deployment on a Unity XT array, to determine the correct array model, the number and type of front-end I/O modules, and the disk configuration, you will need to know:
An SAP HANA node can be either a single (scale-up) SAP HANA server or an SAP HANA worker node which is part of an SAP HANA multihost cluster. Multiple SAP HANA nodes can be connected to a Unity XT storage array provided the maximum number of SAP HANA nodes, as specified in Table 2, is not exceeded.
For more information, see SAP HANA capacity requirements.
Dell Technologies performed extensive testing using the SAP HANA-HWC-ES-1.1 certification scenario to determine the scalability of the Unity XT family. The following table shows the number of SAP HANA nodes that are supported on a specified Unity XT array model. These numbers represent the maximum number of SAP HANA production nodes that can be connected to the Unity XT while still meeting the SAP performance KPIs.
Protocol | 380/380F | 480/480F | 680/680F | 880/880F |
FC | 8 | 16 | 20 | 24 |
NAS (NFS) | 6 | 12 | 16 | 20 |
Achieving these numbers in a customer environment requires:
