2.4 HUAWEI CLOUD ServicesFor large enterprises, it helps them address problems in cloud transformation andenables them to take better advantages of business opportunities in the future.For small and medium enterprises, it provides suitable infrastructure services andaccompanies their growth.

For details of the service portfolio, see HUAWEI CLOUD product portfolio.

● Elastic Cloud Server (ECS)ECS is provided for you to obtain scalable cloud servers by self-service at anytime to build a reliable, secure, flexible, and efficient application environmentto ensure the stable and continuous running of your services.SAP NetWeaver instances are deployed on ECSs.For details, see Elastic Cloud Server Overview.

● Elastic Volume Service (EVS)EVS provides persistent block storage for services such as ECS and Bare MetalServer (BMS). With advanced data redundancy and cache accelerationcapabilities, EVS offers high availability and durability with an extremely lowlatency. In a similar way for traditional hard disks on servers, you can formatEVS disks that are attached to ECSs, create file systems on EVS disks, andstore data into them persistently.All SAP NetWeaver ECSs have EVS disks attached.For details, see Elastic Volume Service Overview.

● Virtual Private Cloud (VPC)VPC enables you to provision logically isolated, configurable, and manageablevirtual networks on HUAWEI CLOUD. You have full control over your virtualnetworks, for example, assigning EIPs, allocating bandwidth, creating subnets,and configuring DHCP and security groups.All SAP NetWeaver ECSs locate in the same VPC. They are isolated using VPCsubnets and network groups for network security.For details, see Virtual Private Cloud User Guide.

● Image Management Service (IMS)IMS manages images. IMS allows you to create ECSs using images. An imageis an ECS template that contains an OS and may also contain proprietarysoftware and application software, such as database software.When creating an SAP NetWeaver ECS, select a proper public image, seeOperating Systems for supported OS types.For details, see Image Management Service User Guide.

2.6 NetworkYou can configure what is known as a VPC service with HUAWEI CLOUD, whichenables you to control your virtual network environment. By using functions fornetwork security and security groups, you thus increase your own networksecurity. You can set up a public IP address for your VPC in order to connect it witha public network via the Elastic IP (EIP) service.

For details, see Virtual Private Cloud User Guide.

Options for VPC connectivity on HUAWEI CLOUD

HUAWEI CLOUD provides certain options to connect the users and on-premisessystems with SAP systems running on HUAWEI CLOUD.

● Direct Internet connectionThis is a quick and easy way to connect to your SAP systems running onHUAWEI CLOUD.For details, see Direct Internet on HUAWEI CLOUD.Use cases: Recommended for Demo, Training and PoC systems

● Direct ConnectDirect Connect allows you to set up a dedicated network connection betweenthe public cloud system and your local data center, office, or collocationenvironment. This helps reduce network latency and provides a moreconsistent and reliable network experience than Internet-based connections.For details, see Direct Connect on HUAWEI CLOUD.Use cases: Recommended for customers who require dedicated networkconnection with greater bandwidth and lower latency

● VPNFor a secure connection between your on-premises systems and the systemsrunning on HUAWEI CLOUD, use a VPN via Internet.For details, see VPN on HUAWEI CLOUD.Use cases: Recommended for any SAP scenario including production, whichrequires VPN integration with on-premise environment

2.7 SecurityHUAWEI CLOUD ensures end-to-end security and privacy.

HUAWEI CLOUD security services are built on the basis of many years ofexperience with managing data centers for different customers, and ensure theseparation of data access. We support you with documenting and using thesefeatures, allowing you to build up a secure application environment on HUAWEICLOUD that ensures the availability, confidentiality and integrity you need for yoursuccessful business.

As with an on-premises infrastructure, you are responsible for using these featuresand creating a secure application environment.

Shared responsibility environment

https://support.huaweicloud.com/intl/en-us/usermanual-vpn/vpn_04_0501.html

Huawei and the customer share responsibility for the security of systems runningon HUAWEI CLOUD.

Huawei manages, controls and operates the physical security of the facilities inwhich the services run up to the components of the host operating system. Thereis a valid security approval for the HUAWEI CLOUD, and all security measuresfrom the strong Huawei group directives are fulfilled.

The customer is responsible for the security (including updates and securitypatches) of guest operating systems, the configuration of HUAWEI CLOUD VPCand HUAWEI CLOUD security groups as well as the firewall setup.

The network resources within a HUAWEI CLOUD VPC are totally separate, and theresources are used exclusively within this VPC.

● Access control

You can set up multi-dimensional access protection using security groups andfirewalls, and thus suitably restrict access to sensitive data. This functionalityis especially in demand within the enterprise environment.

● Software-defined network

The network configuration and the configuration of Dynamic HostConfiguration Protocol (DHCP) enable you to connect a VPN to othernetworks, as well as to the Internet, of course. These configurations becomeeffective automatically and are immediately active.

2.8 ECS FlavorsA special configuration of CPU, memory, storage, I/O and network capabilities isappropriate for each use case. Consult the corresponding SAP Note 2582296 forinformation about the certified ECS types. A list of the certified ECS types isincluded in this documentation.

For specific details about running SAP NetWeaver on HUAWEI CLOUD, refer toSAP notes mentioned in Using SAP Notes.

2.10 DatabasesThe installation, configuration, and management of the underlying database torun SAP NetWeaver application server ABAP and Java on HUAWEI CLOUD issimilar to a physical or virtual server. For SAP NetWeaver application server ABAPand Java, you must use one of the databases certified by SAP for HUAWEI CLOUDlisted in SAP Note mentioned in Using SAP Notes.

Database Licenses

The Bring Your Own License (BYOL) model for database licenses is implementedfor SAP NetWeaver application server ABAP and Java Solutions on HUAWEICLOUD. You are responsible for holding the required database license andcomplying with the database vendor's licensing terms and conditions.



2.11 StorageWith EVS disks, HUAWEI CLOUD provides scalable virtual block storage devices.You can create EVS disks online and attach them to the ECS. You can use EVS disksin the same manner as conventional hard disks. Compared with conventional harddisks, the EVS disks are easier to handle and have better I/O throughput andreliability.

With Object Storage Service (OBS), HUAWEI CLOUD offers a RepresentationalState Transfer (REST) API-compatible object-oriented storage.

EVS disk types

● Ultra-high I/O EVS diskEVS disks that use solid state disk (SSD). These EVS disks provide ultra-highI/O and low latency.IOPS: up to 20,000; data throughput rate: up to 320 MB/s; response period: 1to 3 ms.

● High I/O EVS diskEVS disks that use serial attached SCSI (SAS). These EVS disks provide highI/O and low latency.IOPS: up to 3,000; data throughput rate: up to 120 MB/s; response period: 6 to10 ms

2.12 SAP Support and MonitoringFor full support of SAP NetWeaver solutions running on HUAWEI CLOUD, theguidelines in SAP Note mentioned in Using SAP Notes must be met.

By default, the Data Provider for SAP has been installed on an ECS which iscreated using the public image for SAP. For details about how to manually installor uninstall the Data Provider for SAP, see Data Provider for SAP User Guide.

To enable SAP monitoring (SAPOSCOL) to obtain configuration and resourceutilization information from the underlying HUAWEI CLOUD infrastructure, DataProvider for SAP collects monitoring data from various sources to meet SAPrequirements. The Data Provider is already included in the OS image. The onlything you need to do is to define the access permissions in an agency. Every SAPNetWeaver ECS needs to run it during the whole lifecycle.

1. The process status could be checked by:ps -ef | grep dataprovider | grep python3If information similar to the following is displayed, the dataprovider anddataprovider_update processes are running properly:

When the process statuses are not displayed as expected, the processes couldbe restarted manually by running the following commands:systemctl restart hwdataproviderp3



https://support.huaweicloud.com/intl/en-us/dpug-sap/sap_01_0001.html

systemctl status hwdataproviderp32. Run the following command to obtain the log file of Data Provider:

/var/log/huawei/dataprovider/3. Run the following command to obtain the XML file that stores all indicator

information:wget http://localhost:8888/information.xml

2.13 SAP Installation MediaIn general, there are two options for copying SAP installation media to HUAWEICLOUD:

● Download from SAP official website to HUAWEI CLOUD ECS.Connect to the SAP official website from the ECS and download the requiredinstallation media.

● Copy from your network to HUAWEI CLOUD ECS.Connect to an ECS within your VPC and copy the required installation mediadirectly.

You can create a specific disk to store all your installation media. Then you canattach this disk to various ECSs. For parallel use of the disk we offer snapshottechnology, this enables you to attach the disk to different ECSs at the same time,with this you can improve the overall deployment time.

4.1 Deploying SAP Systems on HUAWEI CLOUD

4.1.1 Creating a HUAWEI CLOUD AccountTo implement an SAP system on the HUAWEI CLOUD, you need an account forthe HUAWEI CLOUD. With this account, you are able to use all HUAWEI CLOUDservices, but you are only charged for the services used. This implementationfollows the "Pay-per-use" concept.

Registering a HUAWEI CLOUD account

1. Visit the HUAWEI CLOUD website at https://www.huaweicloud.com/intl/en-us/.If you have registered on HUAWEI CLOUD, you can log in and click Consoleto switch to the management console.

2. In the upper right corner of the page, click Register.3. The registration page is displayed. Enter required information according to the

prompts to register an account. After the registration, the systemautomatically redirects you to your personal information page.

4.1.2 Configuring Network EnvironmentTo create an SAP environment on HUAWEI CLOUD, you need to first configure anetwork where your SAP application servers can run. On the cloud console, youwill find the button "Virtual Private Cloud" to configure your VPC, manage accessto your VPC, and create and configure security groups.

For details, see the following documents:

Virtual Private Cloud User Guide

Virtual Private Cloud API Reference

4.1.3 Creating and Configuring an ECSThe next step is to create ECSs for the SAP Cloud solution. Depending on theenvironment you want to build, you will need ECSs with different configurations of

CPUArchitecture

The value can be x86 or Kunpeng.● x86: The x86-based CPU architecture uses Complex

Instruction Set Computing (CISC). Each instruction can beused to execute low-level hardware operations, and thelength of each instruction is different. Therefore, the numberof instructions is large and they are complex. Executingthese instructions is complex and time-consuming.

● Kunpeng: The Kunpeng-based CPU architecture usesReduced Instruction Set Computing (RISC). RISC is amicroprocessor that executes fewer types of computerinstructions but at a higher speed than CISC. RISC simplifiesthe computer architecture and improves the running speed.Compared with the x86-based CPU architecture, theKunpeng-based CPU architecture has a more balancedperformance and power consumption ratio. Kunpengfeatures high density, low power consumption, and highcost-effectiveness.

4.1.4 Installing an SAP SystemAfter an ECS is created and configured on HUAWEI CLOUD, you need modify theconfigurations on the ECS where SAP NetWeaver is deployed and then start theinstallation of the SAP system. Follow the standard SAP installation processrecorded in the SAP installation guide. The installation process on an ECS is thesame as that on any other physical or virtual server. For more information aboutusing SAP Software Provisioning Manager, see SAP WIKI Software ProvisioningManager.

Procedure

Step 1 Log in to the ECS where the SAP application software is deployed as user root.

Step 2 Comment out manage_etc_hosts: localhost in the configuration file.

1. Run the following command to open the Cloud-Init configuration file /etc/cloud/cloud.cfg:vi /etc/cloud/cloud.cfg

2. Comment out manage_etc_hosts: localhost in the configuration file and savethe modification.Example: #manage_etc_hosts: localhost

Step 3 Delete "127.0.0.1 host name host name" from the /etc/hosts file.

1. Run the following command to open the /etc/hosts file:



https://wiki.scn.sap.com/wiki/display/SL/Software+Provisioning+Manager+1.0

https://wiki.scn.sap.com/wiki/display/SL/Software+Provisioning+Manager+1.0

vi /etc/hosts2. Delete "127.0.0.1 host name host name" from the /etc/hosts file and save

the modification.

Step 4 Restart the SAP application on the ECS where the SAP application has beeninstalled. If the SAP application has not been installed on the ECS, perform thepreceding operations and install the SAP software.

----End

4.1.5 Performing Post-Installation OperationsWhen the installation process is finished, start the required post installation stepsas described in https://help.sap.com/viewer/nwguidefinder.

4.1.6 (Optional) Creating a Backup for a Custom VMYou should create an image of the VM when you have completed the SAPinstallation and post-installation steps. For details, see Image ManagementService User Guide.

4.2 (Optional) Migrating an Existing SAP System toHUAWEI CLOUD

You can migrate a system copy to the HUAWEI CLOUD. There are two possiblemethods for performing a system copy to the HUAWEI CLOUD. The first is the



https://help.sap.com/viewer/nwguidefinder



database-independent method using the SAP tool SWPM (Software ProvisioningManager). This method is also suitable for homogenous and heterogeneoussystem copies.

Step 1 Use SWPM to export all the SAP objects on your source system to a database-independent format.

Step 2 Set up the target system on HUAWEI CLOUD as described in the installation guidefor SAP.

Step 3 Transfer the export files to the ECS on HUAWEI CLOUD.

Step 4 Use SWPM to import the export files to the target system.

Step 5 Perform the post migration steps.

----End

Another method is to perform a database-specific system copy. This is usually thefaster way to copy the system. The rough steps are:

Step 1 Create a database backup on the source system.
