2. How can I control cost?

 

You are responsible for operating your AWS account and paying for the hosting costs. A great way to minimize costs is to stop your instance when you are not using it. Starting your instance just takes a few minutes, so you can fire it up when you need it. To stop your instance, go to AWS EC2 console, right click the instance and choose "Stop" from the context menu. To start it again, choose "Start" from the same context menu.

 

Please note that even after stopping the EC2 instance, there are a few items that can still incur costs, such as EBS volumes. If you wish to stop using your HANA One instance, and do not want to pay related monthly bills, you will need to terminate your instance.

 

To terminate your instance, choose "Terminate" from your context menu. Once the instance is terminated, by default, only the root volume is deleted; other EBS volumes attached to the instance are not deleted automatically. If you wish to terminate your instance and no longer need your data, you may delete detached EBS volumes using AWS EC2 Console or AWS APIs to avoid storage charges for unused EBS volumes.

 

AWS also provides tools to monitor your usage, so there are no surprises when you get your monthly bill - from your "My Account / Console" menu on the top right corner of the screen onhttp://aws.amazon.com, choose "Account Activity" and you will see your activity for the current month.


3. How can I set billing alerts?

 

Billing alerts enable you to monitor your AWS usage charges and recurring fees automatically, making it easier to track and manage your spending on AWS. You can set up billing alerts to receive e-mail notifications when your charges reach a specified threshold. First 10 alerts are free. Please check AWS website for the latest services.

Please visit https://portal.aws.amazon.com/gp/aws/developer/account/index.html?ie=UTF8&action=billing-alerts&amp to setup billing alerts.



Getting Started and Deployment Considerations

 

 

1. What is the maximum database size for SAP HANA One?


There are few flavors of compute optimized instance available from SPS7 onwards -

 

    • cc2.8xlarge (Previous generation) 60.5 GB memory.
    • c3.8xlarge (Current generation) 60 GB memory. This type provides 32 performing processors.
    • c4.8xlarge  (Current generation) 60 GB memory. This type provides 36 performing processors

 

However, for optimal performance, we do not recommend exceeding the size of the database beyond the 30 GB in memory.

 

 

2. What do I do if I outgrow the maximum database size?

 

Consider using SAP HANA on-premise for database requirements that exceeds AWS’s current offering.

 

 

3. Can I use AWS clustering functionality?

 

This is not currently supported for SAP HANA One.

 

 

4. How do I load data to my SAP HANA One instance?

 

You can load data to your SAP HANA One instance by importing CSV files.

 

 

5. What is the performance on SAP HANA One as compared to SAP HANA on-premise?

 

For a similar number and type of CPU cores, memory and I/O configuration, SAP HANA One is comparable to SAP HANA on-premise. Your actual performance will vary based on the nature of workload.

 

 

6. If SAP or another source system is connecting from onsite to SAP HANA One, what is the network bandwidth?

Network bandwidth in this case is dependent on the bandwidth available at the onsite location.

 

 

7. What happens if there’s a hardware failure? Who is responsible, SAP or Amazon? What should a customer do?

If your SAP HANA One instance fails, you can start up again using the AWS Console or through an API call. All storage volumes associated with your instance are automatically attached to your new instance.

 

 

Security & Backup

 

1. How do I recover lost data?

 

SAP HANA One is configured to back up data and log to a separate 200 GB EBS volume from which data can then be recovered. Log backup is performed periodically as needed. We recommend performing data backup periodically. Additionally, backup should be done before any system upgrade to protect data and HANA artifacts.

 

2. What happens to my data when I shut down the SAP HANA One instance?

 

The SAP HANA One instances are backed up by persistent data stores and volumes and will remain attached until the user terminates the instance. Once the instance is terminated, by default, only the root volume is deleted. The data, log, and backup volumes are not deleted automatically. Those volumes can be attached to other instances if required. If the instance is not needed anymore, make sure to delete all the EBS volumes to avoid storage charges for unused EBS volumes.

 

 

3. How secure is the Amazon EC2 environment to run my SAP HANA Database?

 

AWS provides industry-standard security, and instances can be configured according to your specific needs. Please refer to AWS security features at http://http://aws.amazon.com/securityaws.amazon.com/security.  More advanced features like Virtual Private Cloud can provide more fine-grained control over security.



4. Can a SAP HANA One backup be restored into an on-premise instance of SAP HANA?

 

Yes, as long as SAP HANA One and SAP HANA on-premise licenses are valid, and the SAP HANA versions match, backup data can be transferred. Please follow your license agreements carefully before you transfer any data between SAP HANA One and SAP HANA on-premise.

 

5. Do I need to install Secure Backup media and administrative servers in order to do Cloud backup?

 

Special backup media is not required. The SAP HANA One instances are pre-configured with 200GB of

EBS volumes for data backups. We also provide option to backup on S3 as well. For added data security, snapshots of these volumes can be created on AWS.

 

 

6. If I would like to have additional backup is this possible other than the local EBS Volume?

 

Yes, In our new release we now have the option to backup in a S3 bucket. Simply select this option when taking a backup from the respective Console page of the HANA instance.
