Creating ECSs for SAP NetWeaver

Scenarios

SAP NetWeaver runs on ECSs. Create one or more ECSs based on the deployment mode.

Determine the number of ECSs and related planning information based on sections "Solution Introduction" and "Data Planning".

Procedure

1. On the public cloud management console, click in the navigation pane on the left, and choose Computing > Elastic Cloud Server to switch to the Elastic Cloud Server page.
2. Click Buy ECS on the right. A page for creating ECSs is displayed.
3. Configure the parameters listed in Table 1.

   Table 1 SAP NetWeaver 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 the ECS is located. Select 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	Set the type of SAP NetWeaver ECSs to High-performance computing. Set the ECS specifications based on Recommended ECS Planning or site requirements.
   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	Plan the system disk and data disk by referring to section Recommended ECS Planning. Plan the file systems based on scenarios and recommended file system planning in section Solution Introduction.

4. Click Next: Configure Network.
   Configure network information for the SAP NetWeaver ECS as prompted.

   Table 2 SAP NetWeaver ECS network configuration

   Parameter	Description
   Network	Choose the VPC and subnet in specified in Creating a Subnet and Configuring a Security Group.
   Extension NIC	Create an NIC by referring to section Network Planning.
   Security Group	Use the security group in section Creating a Subnet and Configuring a Security Group.
   EIP	Do not bind an EIP to an ECS. The SAP NetWeaver ECS on the private subnet can be accessed through the NAT server.

5. Click Next: Configure Advanced Settings.
   Configure parameters in advanced settings of the SAP NetWeaver ECS as prompted.

   Table 3 SAP NetWeaver ECS advanced configuration

   Parameter	Description
   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 SAP-Dev in ECS Name, the first ECS is SAP-Dev-0001, and the second ECS is SAP-Dev-0002.
   Login Mode	Select Key pair.
   Key Pair	This parameter is available only when the Login Mode is set to Key pair. The SSH key certificate will be used for logging in to an SAP NetWeaver ECS. Ensure that the ECSs where SAP NetWeaver and NAT server are to be deployed use the same key. Otherwise, SAP NetWeaver installation will fail. 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 ECS. Click Create Key Pair. On the Key Pair page that is displayed, 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. The following options are provided: 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	Specify an SAP NetWeaver ECS group. When you create ECSs, the system will allocate the ECSs in the same server group to different physical servers to ensure the running reliability of these ECSs. Determine the policy of an SAP NetWeaver ECS group based on the deployment mode: Standardized deployment: You do not need to specify an ECS group. Distributed HA deployment: All SAP NetWeaver ECSs must belong to the same ECS group. NOTE: Perform the following operations to create an ECS group: 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. You need to specify the DataproviderAccess agency for the SAP NetWeaver ECS to interconnect with Data Provider. For details about how to create an agency, see the Data Provider for SAP User Guide.

6. Click Next: Confirm.
   Confirm the configuration information about the SAP NetWeaver ECS.

   Table 4 SAP NetWeaver ECS configuration information

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

7. Click Next and complete the payment as prompted.
8. 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.
9. After the SAP NetWeaver ECS is created, you can view the ECS from the ECS list on the right of the page.
10. Create other SAP NetWeaver ECSs as required.
11. Change the root password for logging in to all SAP NetWeaver ECSs.
    Properly keep the root password. In addition, ensure that all SAP ECSs use the same root password.

    1. Use the key to log in to the SAP NetWeaver ECSs.
    2. Run the following command to change the password for user root:

       passwd

       Enter the password as prompted for confirmation.
