Creating an SAP HANA Studio ECS

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. In the navigation plane on the left, click and choose Computing > Elastic Cloud Server.
4. On the right side of the page, click Buy ECS.
5. Configure basic settings of the SAP HANA Studio ECS as prompted.

   Table 1 SAP HANA Studio ECS basic configuration

   Parameter	Description
   Billing Mode	Select a billing mode based on the site requirements. The recommended billing mode is Yearly/Monthly.
   AZ	Specifies the AZ where ECSs are located. Choose an AZ as required.
   CPU Architecture	The value can be x86 or Kunpeng. x86: The X86-based CPU architecture uses Complex Instruction Set Computing (CISC). Each instruction can be used to execute low-level hardware operations, and the length of each instruction is different. Therefore, the number of instructions is large and they are complex. Therefore, executing such an instruction is complex and time-consuming. Kunpeng: The Kunpeng-based CPU architecture uses Reduced Instruction Set Computing (RISC). RISC is a microprocessor that executes fewer types of computer instructions but at a higher speed than CISC. RISC simplifies the computer architecture and improves the running speed. Compared with the x86-based CPU architecture, the Kunpeng-based CPU architecture has a more balanced performance and power consumption ratio. Kunpeng features high density, low power consumption, high cost-effectiveness.
   Specifications	Select All generations and s1.xlarge (4 vCPUs, 16 GB memory).
   Image	Select Marketplace image and click Select Image. In the displayed Select Marketplace Image dialog box, enter SAP in the search box and select the target image.
   System Disk	80 GB For details about disk requirements, see section Other Nodes.

6. Click Next: Configure Network.
7. Configure network information for the SAP HANA Studio ECS as prompted.

   Table 2 SAP HANA Studio ECS network configuration

   Parameter	Description
   Network	Choose the VPC and subnet created in Creating a VPC and Creating a Subnet and Configuring a Security Group.
   Extension NIC	Select the target NIC based on Network Planning.
   Security Group	Choose the security group created in section Creating a Subnet and Configuring a Security Group.
   EIP	Set the parameter as required.
   EIP Type	This parameter is available only when EIP is set to Auto assign. Set this parameter based on the site requirements. Dynamic BGP provides automatic failover and load balancing capabilities and makes better routing decisions based on optimal paths when a network connection fails. Static BGP gives you more control over the routes but route configuration and update are usually time-consuming and error-prone.
   Billed By	This parameter is available only when EIP is set to Auto assign. Billed by indicates the bandwidth billing mode of the purchased EIP, which includes the following options: Bandwidth: The billing will be based on the duration for which the bandwidth is used. Traffic: The billing will be based on the total traffic irrespective of the duration for which the bandwidth is used. Shared bandwidth: The bandwidth can be used by multiple EIPs. NOTE: A bandwidth can be shared between a limited number of EIPs. If the number of EIPs cannot meet service requirement, switch to a higher shared bandwidth or apply for expanding the EIP quota of the existing bandwidth. EIPs that are billed yearly/monthly do not support shared bandwidths. When a shared bandwidth that is billed yearly/monthly expires, the system automatically deletes the bandwidth configuration and creates a dedicated bandwidth billed by traffic for the EIPs sharing the deleted bandwidth configuration.
   Bandwidth Size	This parameter is available only when EIP is set to Auto assign. Set this parameter based on the site requirements.

8. Click Next: Configure Advanced Settings.
9. Configure advanced settings for the SAP HANA Studio ECS as prompted.

   Table 3 SAP HANA Studio ECS advanced configuration

   Parameter	Description
   ECS Name	Specifies the ECS name. For more details, see SAP Note 611361.
   Login Mode	Select Key pair.
   Key Pair	This parameter is available only when the Login Mode is set to Key pair. An SSH key certificate is used for authenticating users who attempt to log in to the ECSs. To create a key pair, click Create Key Pair. On the displayed Key Pair page, click Create Key Pair. Ensure that the HANA ECSs/ECSs where SAP HANA, SAP HANA Studio, and NAT servers are to be deployed use the same key. Otherwise, SAP HANA installation will fail. NOTE: If you choose an existing SSH key certificate from the drop-down list, make sure that you have saved the certificate locally. Otherwise, you may fail to log in to the HANA ECS or ECS. To create a key, do as follows: Click Create Key Pair. On the displayed Key Pair page, click Create Key Pair, specify the key pair name, and click OK. In the Information dialog box that is displayed, click OK. Then, you can query and save the private key as prompted.
   Cloud Backup and Recovery	Cloud Backup and Recovery (CBR) provides backup protection for EVS disks and ECSs, and uses backups to restore the EVS disks and ECSs. After you set Cloud Backup and Recovery, the system binds the target ECS to the cloud backup vault and associates the ECS with the selected backup policy to periodically back up the ECS. You can select one of the following three options for EIP as required: Auto assign Set the name of the cloud backup vault, which is a character string consisting of 1 to 64 characters, including letters, digits, underscores (_), and hyphens (-). For example, vault-f61e. The default naming rule is vault_xxxx. Enter the vault capacity, which is required for backing up the ECS. The vault capacity cannot be smaller than that of the ECS to be backed up. Its value ranges from the total capacity of the ECS to 10,485,760 in the unit of GB. Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one. Use existing Select an existing cloud backup vault from the drop-down list. Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one. Not required: This function is not required. If you require this function after purchasing the ECS, log in to the CBR console and bind the desired cloud backup vault to your ECS.

10. Click Next: Confirm.
11. Confirm the SAP HANA Studio ECS configuration as prompted.

    Table 4 SAP HANA Studio ECS configuration information

    Parameter	Description
    Enterprise Project	Select the name of a created enterprise project, for example, SAP.
    Service Duration	Set the duration based on the site requirements.
    Quantity	Set this parameter as required.
    Agreement	Select I have read and agree to Huawei Image Disclaimer.

12. Click Next and complete the payment as prompted.
13. The system returns to the Elastic Cloud Server page. Check the status of the created task in Task Status on the right of the page.

    After the ECS is created, you can view the ECS from the ECS list on the right of the page.
