Use Table 5 and Table 6 to estimate the initial number of SAP HANA production nodes that can be connected. The guidelines in Table 5 and Table 6 are based on our performance tests on a Unity 400 model and a Unity 350F model using the SAP hwcct tool. The tests were executed without competing workloads.
The SAP HANA node numbers listed in Table 5 and Table 6 are an initial guideline to help you determine the number of SAP HANA worker nodes that can be connected to the Unity array for an existing or planned SAP HANA production environment. The actual number of production SAP HANA nodes that can be connected in a customer environment might be higher or lower, depending on the workload. In customer environments, use the SAP HANA hwcct tool with scenario HANA-HWC-ES 1.1 to validate the SAP HANA performance and determine the maximum number of SAP HANA hosts on a specified storage array.
Dell EMC recommends running regular SAP HANA health checks to verify the performance of the underlying storage environment. SAP HANA configuration mini-checks are described in the following:

Note: We determined the scalability of other Unity x00(F) models by extrapolating the Unity 400 test results using the performance characteristics of the other models.
