Question
A company has grown rapidly in a short period of time. This growth has led to an increase in the volume of data, the performance requirements for storage, and the memory and vCPU requirements for the company’s SAP HANA database that runs on AWS. The SAP HANA database is a scale-up installation. Because of the increased requirements, the company plans to change the Amazon EC2 instance type to a virtual EC2 High Memory instance and plans to change the Amazon Elastic Block Store (Amazon EBS) volume type to a higher performance volume type for the SAP HANA database.
The EC2 instance is a current-generation instance, both before and after the change. Additionally, the EC2 instance and the EBS volume meet all the prerequisites for instance type change and EBS volume type change. An SAP basis administrator must advise the company about whether these changes will require downtime for the SAP system.
Which guidance should the SAP basis administrator provide to the company?
A. The change in EC2 instance type does not require SAP system downtime, but the change in EBS volume type requires SAP system downtime.
B. The change in EC2 instance type requires SAP system downtime, but the change in EBS volume type does not require SAP system downtime.
C. Neither the change in EC2 instance type nor the change in EBS volume type requires SAP system downtime.
D. Both the change in EC2 instance type and the change in EBS volume type require SAP system downtime.
Answer
C. Neither the change in EC2 instance type nor the change in EBS volume type requires SAP system downtime.
Explanation
This is possible due to the hot-plug capability of both current-generation EC2 High Memory instances and the supported EBS volume types for SAP HANA.
