Business and technology considerations influence the sizing of the hardware infrastructure. Consult with your Dell EMC representative to determine a solution design that includes business requirements for performance, response times, availability, data protection, and disaster recovery for the SAP systems.
The following table describes the sequence of steps that are involved in sizing the infrastructure requirements for your TDI deployments:
Table 9. Infrastructure sizing steps
Step |
Activity |
Performed by |
1 |
Determine the number of SAP production systems and SAP HANA systems that are required. |
Dell EMC performs these steps when collecting your business requirements.
|
2 |
Define the SAP system landscapes. Typically, each SAP production system (enterprise resource planning or ERP, business warehouse or BW, customer relationship management or CRM, and so on) has its own SAP system landscape, consisting of a development (DEV), quality assurance (QAS), sandbox (SBX), and production (PRD) environment. |
|
3 |
Determine if virtualization is to be used. |
|
4 |
Determine the high availability requirements. |
|
5 |
Determine the DR requirements and the number of data centers or sites involved. |
|
6 |
Consider data protection requirements for backing up the SAP HANA systems. |
|
7 |
Determine an expected annual data growth and the required number of years of maintenance. |
|
8 |
Size each of the SAP HANA systems and system landscapes using the SAP Quick Sizer tool on your production systems. |
Customer performs this step and then provides the results to Dell EMC. |
9 |
Calculate the total compute requirements and determine the number and models of PowerEdge servers (SAPS, CPU, memory) that are required to support the SAP HANA systems in the TDI deployments |
Dell EMC performs these steps using the information that the customer provides in step 8.
|
10 |
Calculate the total storage requirements based on capacity or IOPS, or both, and determine which Dell EMC enterprise storage system is best suited to meet the customer’s business needs. |
|
11 |
Determine the backup capacity requirements. |
|
12 |
Set up the SAP HANA infrastructure and use HWCCT/HCOT to check that the SAP HANA TDI KPIs are met. |
Customer or Dell EMC Professional Services performs this step. |
13 |
Install the SAP HANA software. |
Customer or Dell EMC Professional Services performs this step. Note: Only SAP HANA certified personnel can perform the installation. |
