大型实例的其他网络要求Additional network requirements for large instances

Azure 上的 SAP HANA 大型实例部署可能有其他网络要求。You might have additional network requirements as part of a deployment of large instances of SAP HANA on Azure.

添加更多 IP 地址或子网Add more IP addresses or subnets

可以使用 Azure 门户、PowerShell 或 Azure CLI 添加多个 IP 地址或子网。Use either the Azure portal, PowerShell, or the Azure CLI when you add more IP addresses or subnets.

将新的 IP 地址范围作为新范围添加到虚拟网络地址空间,而不要生成新的聚合范围。Add the new IP address range as a new range to the virtual network address space, instead of generating a new aggregated range. 向 Microsoft 提交此更改。Submit this change to Microsoft. 这样就可以从新的 IP 地址范围连接到客户端中的 HANA 大型实例单元。This enables you to connect from that new IP address range to the HANA large instance units in your client. 可以发起 Azure 支持请求来添加新的虚拟网络地址空间。You can open an Azure support request to get the new virtual network address space added. 收到确认后,请执行后续步骤。After you receive confirmation, perform the next steps.

要从 Azure 门户创建其他子网,请参阅使用 Azure 门户创建虚拟网络To create an additional subnet from the Azure portal, see Create a virtual network using the Azure portal. 要通过 PowerShell 创建子网,请参阅使用 PowerShell 创建虚拟网络To create one from PowerShell, see Create a virtual network using PowerShell.

添加虚拟网络Add virtual networks

首次连接一个或多个 Azure 虚拟网络后,可能需要连接其他用于访问 Azure 上的 SAP HANA(大型实例)的虚拟网络。After initially connecting one or more Azure virtual networks, you might want to connect additional ones that access SAP HANA on Azure (large instances). 首先,提交 Azure 支持请求。First, submit an Azure support request. 请在请求中包含指明特定 Azure 部署的特定信息。In that request, include the specific information identifying the particular Azure deployment. 此外请包含 IP 地址空间范围或 Azure 虚拟网络地址空间的范围。Also include the IP address space range or ranges of the Azure virtual network address space. 然后,Microsoft 上的 SAP HANA 服务管理部门将提供所需的信息用于连接其他虚拟网络和 Azure ExpressRoute。SAP HANA on Microsoft Service Management then provides the necessary information you need to connect the additional virtual networks and Azure ExpressRoute. 对于每个虚拟网络,需要使用唯一授权密钥连接到 HANA 大型实例 ExpressRoute 线路。For every virtual network, you need a unique authorization key to connect to the ExpressRoute circuit to HANA large instances.

提高 ExpressRoute 线路带宽Increase ExpressRoute circuit bandwidth

咨询 Microsoft 上的 SAP HANA 服务管理部门。Consult with SAP HANA on Microsoft Service Management. 如果他们建议提高 Azure 上的 SAP HANA(大型实例)ExpressRoute 线路的带宽,请创建 Azure 支持请求。If they advise you to increase the bandwidth of the SAP HANA on Azure (large instances) ExpressRoute circuit, create an Azure support request. (可以请求将单条线路的带宽提高到最大 10 Gbps)。完成该操作后,会收到通知;无需执行任何操作即可在 Azure 中提高速度。(You can request an increase for a single circuit bandwidth up to a maximum of 10 Gbps.) You then receive notification after the operation is complete; you don't need to do anything else to enable this higher speed in Azure.

添加其他 ExpressRoute 线路Add an additional ExpressRoute circuit

咨询 Microsoft 上的 SAP HANA 服务管理部门。Consult with SAP HANA on Microsoft Service Management. 如果他们建议添加其他 ExpressRoute 线路,请创建 Azure 支持请求(包含获取连接到新线路的授权信息的请求)。If they advise you to add an additional ExpressRoute circuit, create an Azure support request (including a request to get authorization information to connect to the new circuit). 提出请求之前,必须定义虚拟网络上使用的地址空间。Before making the request, you must define the address space used on the virtual networks. 之后,Microsoft 上的 SAP HANA 服务管理部门才能提供授权。SAP HANA on Microsoft Service Management can then provide authorization.

创建新线路并且 Microsoft 上的 SAP HANA 服务管理部门完成配置后,会收到通知,其中包含继续下一步所需的信息。When the new circuit is created, and the SAP HANA on Microsoft Service Management configuration is complete, you receive a notification with the information you need to proceed. 如果 Azure 虚拟网络已连接到同一 Azure 区域中的另一条 Azure 上的 SAP HANA(大型实例)ExpressRoute 线路,则无法连接到此附加线路。You are not able to connect Azure virtual networks to this additional circuit if they are already connected to another SAP HANA on Azure (large instance) ExpressRoute circuit in the same Azure region.

删除子网Delete a subnet

可以使用 Azure 门户、PowerShell 或 Azure CLI 来删除虚拟网络子网。To remove a virtual network subnet, you can use the Azure portal, PowerShell, or the Azure CLI. 如果 Azure 虚拟网络 IP 地址范围或地址空间是一个聚合范围,则不需要与 Microsoft 协调。If your Azure virtual network IP address range or address space was an aggregated range, there is no follow up for you with Microsoft. (不过,需要注意的是,虚拟网络仍会传播包含已删除子网的 BGP 路由地址空间。)可能已经将 Azure 虚拟网络地址范围或地址空间定义为多个 IP 地址范围,其中一个已分配给已删除的子网。(Note, however, that the virtual network is still propagating the BGP route address space that includes the deleted subnet.) You might have defined the Azure virtual network address range or address space as multiple IP address ranges, of which one was assigned to your deleted subnet. 请确保从虚拟网络地址空间中删除该子网。Be sure to delete that from your virtual network address space. 然后通知 Microsoft 上的 SAP HANA 服务管理部门,以将其从 Azure 上的 SAP HANA(大型实例)能够进行通信的范围中删除。Then inform SAP HANA on Microsoft Service Management to remove it from the ranges that SAP HANA on Azure (large instances) is allowed to communicate with.

有关详细信息,请参阅删除子网For more information, see Delete a subnet.

删除虚拟网络Delete a virtual network

有关信息,请参阅删除虚拟网络For information, see Delete a virtual network.

Microsoft 上的 SAP HANA 服务管理部门会删除对 Azure ExpressRoute 线路上的 SAP HANA(大型实例)的现有授权。SAP HANA on Microsoft Service Management removes the existing authorizations on the SAP HANA on Azure (large instances) ExpressRoute circuit. 它还会删除与 HANA 大型实例进行通信的 Azure 虚拟网络 IP 地址范围或地址空间。It also removes the Azure virtual network IP address range or address space for the communication with HANA large instances.

删除虚拟网络后,请提出 Azure 支持请求并提供要删除的 IP 地址空间范围。After you remove the virtual network, open an Azure support request to provide the IP address space range or ranges to be removed.

若要确保删除所有内容,请删除 ExpressRoute 连接、虚拟网络网关、虚拟网络网关公共 IP 和虚拟网络。To ensure you remove everything, delete the ExpressRoute connection, the virtual network gateway, the virtual network gateway public IP, and the virtual network.

删除 ExpressRoute 线路Delete an ExpressRoute circuit

若要删除某个附加的 Azure 上的 SAP HANA(大型实例)ExpressRoute 线路,请向 Microsoft 上的 SAP HANA 服务管理部门提出 Azure 支持请求。To remove an additional SAP HANA on Azure (large instances) ExpressRoute circuit, open an Azure support request with SAP HANA on Microsoft Service Management. 请求删除该线路。Request that the circuit be deleted. 在 Azure 订阅中,可以根据需要删除或保留虚拟网络。Within the Azure subscription, you may delete or keep the virtual network, as necessary. 但是,必须删除 HANA 大型实例 ExpressRoute 线路与链接的虚拟网络网关之间的连接。However, you must delete the connection between the HANA large instances ExpressRoute circuit and the linked virtual network gateway.
