Virtual Server for SAP

Functions Included

• Compute

  • Enabling/disabling of an environment

    Specify a project and availability zone, and set whether to enable the virtual server for SAP environment.

    Note: If you disable this environment, you must delete all created virtual servers for SAP, images, and network resources in the project.

  • A virtual server for SAP

    • Creating/deleting a virtual server for SAP
    • Startup/termination of a virtual server for SAP
    • Restarting a virtual server for SAP
    • Acquiring information for a virtual server for SAP

  • OS provision service

    Use the images provided in List of Available OS of Virtual Server for SAP to create a virtual server for SAP.

    You can use Windows Server Update Services and Windows Activation (KMS), which are common network services.

  • Software support service

    The available functions and charge systems comply with Compute > Standard Services > Software Support Services.

  • Auto recovery of a virtual servers (Automatic failover)

    If the server stops during an operation due to issues such as failure of the physical host machine at the data center, the virtual server that was operating on that host machine is automatically moved to a different host machine and the server operates there.

    Note:

    • The automatic failover (automatic recovery) function is always enabled (it cannot be disabled). When automatic failover is completed, a notification email is sent to the overall administrator of the project the target resource belongs to. For details on notification emails, refer to Automatic Failover Notification Messages.

    • If Auto-Failover is performed while virtual servers are being started or stopped, they may have a different power status from the assumed status.

      In such cases, manually perform the power operation for the virtual server. If the power status does not change within around 10 minutes, perform the power operation again.

  • Image management

    Create private images from an existing virtual server for SAP and delete private images that have been created.

    Tip: A private image that has been created can be used only in the activity zone in which it was created.

    Choose to disclose a created private image either within the project or within the domain.

• Storage

  • Storage Type

    There are the following types of storage.

    Table 1. List of Storage Types

    Class	Storage Type
    Standard Type	M1
    High Performance Type	H2

    Note: The storage type can be selected when adding a disk to a virtual server. You cannot change the storage type after a disk has been added.

    • Standard Type

      The standard type is efficient in cost performance.

      Table 2. Purposes and Disk Sizes of the Standard Type

      Storage Type	Purpose	Disk Size
      M1	When you deploy application data that requires frequent file access (reading and writing) When you handle a lot of large data files	0.1 - 2047 GB (in units of 0.1 GB)

    • High Performance Type

      For high performance type, the performance of the storage improves, as the disk size increases.

      Table 3. Purposes and Disk Sizes of the High Performance Type

      Storage Type	Purpose	Maximum IOPS/GB	Disk Size
      H2	For small-scale or medium-scale DBs, when storing application data that requires data throughput.	5 IOPS/GB *1	512 - 2047 GB (in units of 1 GB)

      *1: IOPS is calculated with a block size of 16 KB. Performance varies depending on the operating environment and other factors. There is no guarantee for a certain level of performance.

      Note:

      • The high performance type cannot be specified for the following. These are fixed as standard type.

        • System storage
        • Additional storage created when creating a virtual server
      • Storage performance varies in proportion to the disk size. Therefore, a disk with a small storage size may not produce enough storage performance.

  • System Storage

    System storage is provided as a system region for starting the OS. The size of system storage is determined according to the OS image selected in the OS provision service.

    Standard type storage is used for system storage.

    Table 4. List of System Storage Sizes (Eastern Japan Region 1, Western Japan Region 2)

    OS Type	OS Provided	Size
    Windows	Windows Server 2016 SE 64bit English Version	180 GB
    	Windows Server 2012 R2 SE 64bit English Version	180 GB
    	Windows Server 2008 R2 SE SP1 64bit English Version	180 GB
    	Windows Server 2016 SE 64bit Japanese Version	80 GB
    	Windows Server 2012 R2 SE 64bit Japanese Version	80 GB
    	Windows Server 2008 R2 SE SP1 64bit Japanese Version	80 GB

  • Additional storage

    Additional storage is provided for data archiving.

    When adding storage to a virtual server, it is possible to select the storage type.

    Table 5. Selectable Additional Storage Types and Sizes

    Storage Type	Size
    Standard Type	0.1 - 2047 GB
    High Performance Type	512 - 2047 GB

    Number of Storage Systems	1 - 55

  • Snapshot function

    This function is used to take, restore, and delete snapshots for existing virtual servers for SAP.

    Note: If you delete a virtual server for SAP in which snapshots are taken, the snapshots will also be deleted.

    Table 7. List of Limiting Values Related to Snapshots

    Item	Limiting Values
    Number of Snapshots Taken	Maximum 10 generations

• Network

  • Network resource management

    For virtual networks and subnets that have been created, you can assign and release network resources for the virtual server for the SAP environment.

    Tip: You can use private IP addresses and gateway IP addresses by assigning network resources.

  • Adding/deleting ports

    Note:

    • If you add or delete ports, also modify the network adapter settings on the OS as appropriate.
    • You cannot use security group functions.
