SAP HANA Nodes

SAP poses specific requirements on HANA ECSs depending on application scenarios.

NOTE:

The time zone of the server on which SAP NetWeaver is deployed must be the same as that of SAP HANA nodes, excepting the specifications described in this section.

Specifications in SoH Scenario

In SoH scenario, SAP HANA works with SAP business suites, such as ERP or CRM. In this scenario, SAP HANA provides OLTP functions. The SAP HANA process latency is the key concern.

Table 1 lists the requirements on HANA ECSs in SoH scenario.

Specifications in BWoH Scenario

In BWoH scenario, SAP HANA works with SAP Business Warehouse. In this scenario, SAP HANA provides OLAP functions and supports rapid computing and analyzing on massive data. The SAP HANA processing performance and the network bandwidths between SAP HANA nodes are the key concern.

Table 2 lists the requirements on HANA ECSs in BWoH scenario.
