Creating an SAP HANA ECS

Procedure

1. Log in to the management console.
2. Click in the upper left corner and select the desired 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 information about the HANA ECS as prompted.

   Table 1 HANA 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. The AZ must support SAP HANA. Choose the 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	Click Large-memory. Select a specification based on section SAP HANA Nodes or as required.
   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	In single-node scenarios, regardless of whether HA is required, one system disk and multiple data disks are required. For details about disk requirements, see section SAP HANA Nodes. If additional disks are required, you can click Add Data Disk to add more disks.

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

   Table 2 HANA ECS network configuration

   Parameter	Description
   Network	Select the VPC and subnet provided in Creating a Subnet and Configuring a Security Group.
   Extension NIC	Determine the number of NICs according to the deployment plan provided in section Network Planning. If you need to add a NIC, click Add NIC. NOTE: In the single-node deployment mode where HA is not required, you do not need to add an extension NIC. In the single-node deployment mode where HA is required, add an extension NIC and deselect Security group disabled.
   Security Group	Use the security group in section Creating a Subnet and Configuring a Security Group.
   EIP	Select Not required.

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

   Table 3 HANA ECS advanced configuration

   Parameter	Description
   ECS Name	Specifies the ECS name. When you create ECSs in batches, the number in the ECS Name is generated automatically in ascending order based on the Quantity value that you filled in. For example, if you fill hana in ECS Name, the first ECS is hana-0001, and the second ECS is hana-0002. 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 HANA 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.
   ECS Group	Specifies a HANA ECS group. When you create ECSs, the system will allocate the HANA ECSs in the same server group to different physical servers to ensure the running reliability of these HANA ECSs. Determine the policy of a HANA ECS group based on the scenario: Single-node where HA is not required: You do not need to specify ECS Group. Single-node scenario where HA is required: The two HANA ECSs must belong to the same ECS Group. NOTE: If no ECS group is available, perform the following operations to create one: Click Create ECS Group. On the displayed page, click Create ECS Group, specify the ECS group name, and click OK.
   Advanced Options	Select Configure now.
   Agency	This parameter is available only when Advanced Options is set to Configure now. After the agency is specified, the delegated domain can obtain the credentials from the agency to temporarily access the public cloud. Data Provider is an SAP indicator collector on the public cloud platform to collect key performance data of ECSs and Cloud Eye in the SAP NetWeaver system and then surface the data to SAP applications. Specify the DataproviderAccess agency to ECSs where SAP HANA and SAP NetWeaver are all deployed. Before using the agency, log in to the public cloud management console as the tenant administrator and create the DataproviderAccess agency. For details about how to create an agency, see the Data Provider for SAP User Guide.

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

14. Create other HANA ECSs as required.
15. Change the password of user root for logging in to all HANA ECSs.
    Securely keep the password of user root. Ensure that the passwords of user root are the same for all HANA ECSs.

    1. Use the key to log in to the SAP HANA ECSs.
    2. Change the password of user root.

       passwd

       Enter the new password as prompted and confirm it.
