概述Overview

可将安装于多台本地计算机上的数据管理网关与门户中的单个逻辑网关相关联。You can associate data management gateways that are installed on multiple on-premises machines with a single logical gateway from the portal. 这些计算机称为 节点These machines are called nodes. 至多可将 4 个节点与一个逻辑网关相关联。You can have up to four nodes associated with a logical gateway. 一个逻辑网关配多个节点(已安装网关的本地计算机)的好处如下:The benefits of having multiple nodes (on-premises machines with gateway installed) for a logical gateway are:

  • 本地和云数据存储之间的数据移动性能提高。Improve performance of data movement between on-premises and cloud data stores.
  • 如果某个节点出于某种原因发生故障,则其他节点仍可用于移动数据。If one of the nodes goes down for some reason, other nodes are still available for moving the data.
  • 如果某个节点需要脱机进行维护,则其他节点仍可用于移动数据。If one of the nodes need to be taken offline for maintenance, other nodes are still available for moving the data.

还可配置可在节点上运行的 并发数据移动作业数,提升本地与云数据存储之间移动数据的能力。You can also configure the number of concurrent data movement jobs that can run on a node to scale up the capability of moving data between on-premises and cloud data stores.

通过使用 Azure 门户,可以监视这些节点的状态,有助于决定是否要从逻辑网关添加或删除节点。Using the Azure portal, you can monitor the status of these nodes, which helps you decide whether to add or remove a node from the logical gateway.

体系结构Architecture

下图概述了数据管理网关的可伸缩性和可用性功能的体系结构:The following diagram provides the architecture overview of scalability and availability feature of the Data Management Gateway:

数据管理网关 - 高可用性和可伸缩性

逻辑网关是向 Azure 门户中数据工厂添加的网关。A logical gateway is the gateway you add to a data factory in the Azure portal. 之前,只能将逻辑网关与一台已安装数据管理网关的本地 Windows 计算机相关联。Earlier, you could associate only one on-premises Windows machine with Data Management Gateway installed with a logical gateway. 这个本地网关计算机被称为节点。This on-premises gateway machine is called a node. 现在,可至多将 4 个物理节点与一个逻辑网关相关联。Now, you can associate up to four physical nodes with a logical gateway. 包含多个节点的逻辑网关被称为多节点网关。A logical gateway with multiple nodes is called a multi-node gateway.

所有这些节点均处于活动状态。All these nodes are active. 它们均可处理数据移动作业,在本地和云数据存储间移动数据。They all can process data movement jobs to move data between on-premises and cloud data stores. 其中一个节点同时充当调度程序和辅助角色。One of the nodes act as both dispatcher and worker. 组中的其他节点作为辅助角色节点。Other nodes in the groups are worker nodes. 调度程序节点从云服务请求数据移动任务/作业,然后将其分派给辅助角色节点(包括其本身)。A dispatcher node pulls data movement tasks/jobs from the cloud service and dispatches them to worker nodes (including itself). 辅助角色节点执行数据移动作业,在本地和云数据存储间移动数据。A worker node executes data movement jobs to move data between on-premises and cloud data stores. 所有节点均为辅助角色。All nodes are workers. 只有一个节点可同时作为调度程序和辅助角色。Only one node can be both dispatch and worker.

通常以一个节点开始,然后随现有节点无力处理数据移动负载而逐渐扩展添加更多节点。You may typically start with one node and scale out to add more nodes as the existing node(s) are overwhelmed with the data movement load. 还可通过 增加 节点上允许运行的并发作业数来增强网关节点的数据移动能力。You can also scale up the data movement capability of a gateway node by increasing the number of concurrent jobs that are allowed to run on the node. 此功能也适用于单节点网关(即便未启用可伸缩性和可用性功能)。This capability is also available with a single-node gateway (even when the scalability and availability feature is not enabled).

包含多个节点的网关可在所有节点间使数据存储凭据保持同步。A gateway with multiple nodes keeps the data store credentials in sync across all nodes. 如果存在节点到节点连接问题,则凭据可能不同步。设置使用网关的本地数据存储的凭据时,会在调度程序/辅助角色节点上保存凭据。If there is a node-to-node connectivity issue, the credentials may be out of sync. When you set credentials for an on-premises data store that uses a gateway, it saves credentials on the dispatcher/worker node. 调度程序节点与其他辅助角色节点同步。The dispatcher node syncs with other worker nodes. 此过程称为 凭据同步。节点之间的信道可以通过公共 SSL/TLS 证书进行 加密This process is known as credentials sync. The communication channel between nodes can be encrypted by a public SSL/TLS certificate.

    数据管理网关 - 添加节点菜单

    按照上一节中的说明来设置节点。Follow instructions from the previous section to set up the node.

安装最佳做法Installation best practices

  • 在主机上为网关配置电源计划,从而让计算机无法休眠。Configure power plan on the host machine for the gateway so that the machine does not hibernate. 如果主机计算机进入休眠状态,则网关不响应数据请求。If the host machine hibernates, the gateway does not respond to data requests.
  • 备份与网关关联的证书。Back up the certificate associated with the gateway.
  • 确保所有节点的配置类似(建议),以获得理想性能。Ensure all nodes are of similar configuration (recommended) for ideal performance.
  • 添加至少两个节点来确保高可用性。Add at least two nodes to ensure high availability.

TLS/SSL 证书要求TLS/SSL certificate requirements

下面是用于保护集成运行时节点间通信的 TLS/SSL 证书的相关要求:Here are the requirements for the TLS/SSL certificate that is used for securing communications between integration runtime nodes:

  • 证书必须是公共可信的 X509 v3 证书。The certificate must be a publicly trusted X509 v3 certificate. 建议使用公共(即第三方)证书颁发机构 (CA) 颁发的证书。We recommend that you use certificates that are issued by a public (third-party) certification authority (CA).
  • 每个集成运行时节点都必须信任此证书,以及运行凭据管理器应用程序的客户端计算机。Each integration runtime node must trust this certificate, as well as the client machine that is running the credential manager application.

    备注

    通过复制向导/Azure 门户安全设置凭据时,使用凭据管理器应用程序。Credential manager application is used while securely setting credential from Copy Wizard/ Azure Portal. 这可能是从与本地/专用数据存储位于同一网络的任何一台计算机触发。And this can be fired from any machine within the same network as the on-premises/ private data store.

  • 支持通配符证书。Wild card certificates are supported. 如果 FQDN 名称为 node1.domain.contoso.com,则可以使用 *. domain.contoso.com 作为证书的使用者名称。If your FQDN name is node1.domain.contoso.com, you can use *.domain.contoso.com as subject name of the certificate.
  • 不建议使用 SAN 证书,因为鉴于当前限制,只会使用使用者可选名称的最后一项,其他所有项都会遭忽略。SAN certificates are not recommended since only the last item of the Subject Alternative Names will be used and all others will be ignored due to current limitation. 例如E.g. 有一个 SAN 证书,其中 SAN 为 node1.domain.contoso.com 和 node2.domain.contoso.com,那么只能在 FQDN 为 node2.domain.contoso.com 的计算机上使用此证书。you have a SAN certificate whose SAN are node1.domain.contoso.com and node2.domain.contoso.com, you can only use this cert on machine whose FQDN is node2.domain.contoso.com.
  • 支持 Windows Server 2012 R2 支持的任何密钥大小的 TLS/SSL 证书。Supports any key size supported by Windows Server 2012 R2 for TLS/SSL certificates.
  • 不支持使用 CNG 密钥的证书。Certificate using CNG keys are not supported.

FAQ:何时禁用此加密?FAQ: When would I not enable this encryption?

启用加密会增加一定的基础结构成本(拥有公用证书)。因此,在下列情况下,可以跳过启用加密:Enabling encryption can add certain cost to your infrastructure (owning public certificate) hence you may skip enabling encryption in the below cases:

  • 当集成运行时在受信任的网络上运行,或在采用透明加密(如 IP/SEC)的网络上运行时。When the integration runtime is running on a trusted network, or a network with transparent encryption like IP/SEC. 由于这种通道通信仅在受信任的网络中受限,因此可能无需其他加密。Since this channel communication is only limited within your trusted network, you may not need additional encryption.
  • 当集成运行时不是在生产环境中运行时。When the integration runtime is not running in a production environment. 这样有助于降低 TLS/SSL 证书成本。This can help in reducing TLS/SSL certificate cost.

监视多节点网关Monitor a multi-node gateway

多节点网关监视Multi-node gateway monitoring

在 Azure 门户中,可以查看每个节点上资源使用情况(CPU、内存、网络(进/出)等)的近乎实时的快照以及网关节点状态。In the Azure portal, you can view near-real time snapshot of resource utilization (CPU, memory, network(in/out), etc.) on each node along with statuses of gateway nodes.

数据管理网关 - 多节点监视

可在“网关”页中启用“高级设置”以查看网络(进/出)、角色和凭据状态等高级指标,这有助于调试网关问题以及并发作业数(运行中/上限),可在性能优化期间相应地更改并发作业数。You can enable Advanced Settings in the Gateway page to see advanced metrics like Network(in/out), Role & Credential Status, which is helpful in debugging gateway issues, and Concurrent Jobs (Running/ Limit) which can be modified/ changed accordingly during performance tuning. 下表介绍“网关节点”列表中的列:The following table provides descriptions of columns in the Gateway Nodes list:

监视属性Monitoring Property 说明Description
名称Name 逻辑网关和与网关关联的节点的名称。Name of the logical gateway and nodes associated with the gateway.
状态Status 逻辑网关和网关节点的状态。Status of the logical gateway and the gateway nodes. 示例:联机/脱机/受限/等。有关这些状态的信息,请参阅 网关状态 部分。Example: Online/Offline/Limited/etc. For information about these statuses, See Gateway status section.
VersionVersion 显示逻辑网关和每个网关节点的版本。Shows the version of the logical gateway and each gateway node. 逻辑网关的版本根据组中多数节点的版本而决定。The version of the logical gateway is determined based on version of majority of nodes in the group. 如果逻辑网关安装程序中的节点版本不同,只有与逻辑网关的版本号相同的节点能正常运行。If there are nodes with different versions in the logical gateway setup, only the nodes with the same version number as the logical gateway function properly. 其他节点将处于受限模式,需要手动进行更新(仅当自动更新失败时)。Others are in the limited mode and need to be manually updated (only in case auto-update fails).
可用内存Available memory 网关节点上的可用内存。Available memory on a gateway node. 此值为近实时快照。This value is a near real-time snapshot.
CPU 使用率CPU utilization 网关节点的 CPU 使用率。CPU utilization of a gateway node. 此值为近实时快照。This value is a near real-time snapshot.
网络(进/出)Networking (In/Out) 网关节点的网络利用率。Network utilization of a gateway node. 此值为近实时快照。This value is a near real-time snapshot.
并发作业数(运行中/上限)Concurrent Jobs (Running/ Limit) 每个节点上运行的作业或任务数。Number of jobs or tasks running on each node. 此值为近实时快照。This value is a near real-time snapshot. 上限表示每个节点的最大并发作业数。Limit signifies the maximum concurrent jobs for each node. 此值根据计算机大小定义而来。This value is defined based on the machine size. 在 CPU/内存/网络未充分利用,但活动超时的高级方案中,可以增加限制以增加并发作业的执行。此功能也适用于单节点网关 (,即使未启用) 的可伸缩性和可用性功能也是如此。You can increase the limit to scale up concurrent job execution in advanced scenarios, where CPU/ memory/ network is under-utilized, but activities are timing out. This capability is also available with a single-node gateway (even when the scalability and availability feature is not enabled). 有关详细信息,请参阅扩展注意事项部分。For more information, see scale considerations section.
角色Role 角色有两种类型:调度程序和辅助角色。There are two types of roles – Dispatcher and worker. 所有节点均为辅助角色,表示它们可用于执行作业。All nodes are workers, which means they can all be used to execute jobs. 只有一个调度程序节点,用于从云服务中请求任务/作业,并分派到其他辅助节点(包括其本身)。There is only one dispatcher node, which is used to pull tasks/jobs from cloud services and dispatch them to different worker nodes (including itself).

扩展注意事项Scale considerations

向外扩展Scale out

如果“可用内存较低”且“CPU 使用量较高”,添加新节点有助于跨计算机提高负载。When the available memory is low and the CPU usage is high, adding a new node helps scale out the load across machines. 如果活动因超时或网关节点处于脱机状态而失败,则向网关添加节点会有所作用。If activities are failing due to time-out or gateway node being offline, it helps if you add a node to the gateway.

纵向扩展Scale up

如果可用内存和 CPU 未充分利用,但空闲容量为 0,应通过增加节点上可运行的并发作业数进行纵向扩展。When the available memory and CPU are not utilized well, but the idle capacity is 0, you should scale up by increasing the number of concurrent jobs that can run on a node. 此外,活动因网关重载而超时时,可能也需要进行扩展。You may also want to scale up when activities are timing out because the gateway is overloaded. 如下图所示,可以增加节点的最大容量。As shown in the following image, you can increase the maximum capacity for a node. 建议从加倍开始。We suggest doubling it to start with.

数据管理网关 - 扩展注意事项

已知问题/重大更改Known issues/breaking changes

  • 目前,单个逻辑网关最多可有 4 个物理网关节点。Currently, you can have up to four physical gateway nodes for a single logical gateway. 出于性能原因,如果需要四个以上的节点,请将电子邮件发送到 DMGHelp@microsoft.comIf you need more than four nodes for performance reasons, send an email to DMGHelp@microsoft.com.
  • 不能使用其他逻辑网关中的身份验证密钥重新注册网关节点以从当前逻辑网关进行切换。You cannot re-register a gateway node with the authentication key from another logical gateway to switch from the current logical gateway. 若要重新注册,请从节点中卸载网关,重新安装网关,并使用适用于其他逻辑网关的身份验证密钥进行注册。To re-register, uninstall the gateway from the node, reinstall the gateway, and register it with the authentication key for the other logical gateway.
  • 如果所有网关节点都需要 HTTP 代理,请在 diahost.exe.config 和 diawp.exe.config 中设置代理,并使用服务器管理器确保所有节点都具有相同的 diahost.exe.config 和 diawip.exe.config。有关详细信息,请参阅 配置代理设置 部分。If HTTP proxy is required for all your gateway nodes, set the proxy in diahost.exe.config and diawp.exe.config, and use the server manager to make sure all nodes have the same diahost.exe.config and diawip.exe.config. See configure proxy settings section for details.
  • 若要在网关配置管理器中更改节点到节点通信的加密模式,请在门户中保留一个节点并删除其他所有节点。To change encryption mode for node-to-node communication in Gateway Configuration Manager, delete all the nodes in the portal except one. 然后,在更改加密模式后重新添加节点。Then, add nodes back after changing the encryption mode.
  • 如果选择对节点到节点的通信通道进行加密,请使用官方 TLS 证书。Use an official TLS certificate if you choose to encrypt the node-to-node communication channel. 自签名证书可能导致连接问题,因为相同的证书在其他计算机上的证书验证机构中可能不受信任。Self-signed certificate may cause connectivity issues as the same certificate may not be trusted in certifying authority list on other machines.
  • 如果节点版本低于逻辑网关版本,则不能向逻辑网关注册网关节点。You cannot register a gateway node to a logical gateway when the node version is lower than the logical gateway version. 从门户中删除逻辑网关的所有节点,以便可以注册较低版本节点(降级)。Delete all nodes of the logical gateway from portal so that you can register a lower version node(downgrade) it. 如果删除逻辑网关的所有节点,请向该逻辑网关手动安装并注册新节点。If you delete all nodes of a logical gateway, manually install and register new nodes to that logical gateway. 在这种情况下,不支持快速安装。Express setup is not supported in this case.
  • 快速安装不能用于向现有逻辑网关安装节点,该网关仍使用云凭据。You cannot use express setup to install nodes to an existing logical gateway, which is still using cloud credentials. 可在“设置”选项卡上查看网关配置管理器中存储凭据的位置。You can check where the credentials are stored from the Gateway Configuration Manager on the Settings tab.
  • 快速安装不能用于向现有逻辑网关安装节点,该网关已启用节点到节点加密。You cannot use express setup to install nodes to an existing logical gateway, which has node-to-node encryption enabled. 由于设置加密模式涉及手动添加证书,因此不能选择快速安装。As setting the encryption mode involves manually adding certificates, express install is no more an option.
  • 对于本地环境中的文件副本,不得再使用 \localhost 或 C:\files,因为 localhost 或本地驱动器可能无法通过所有节点进行访问。For a file copy from on-premises environment, you should not use \localhost or C:\files anymore since localhost or local drive might not be accessible via all nodes. 相反,请使用 \ ServerName\files 来指定文件的位置。Instead, use \ServerName\files to specify files' location.

从预览版回退Rolling back from the preview

若要从预览版回退,请保留一个节点、删除所有其他节点。To roll back from the preview, delete all nodes but one node. 删除的节点并不重要,但请确保逻辑网关中至少有一个节点。It doesn't matter which nodes you delete, but ensure you have at least one node in the logical gateway. 可通过在计算机上卸载网关或使用 Azure 门户来删除节点。You can delete a node either by uninstalling gateway on the machine or by using the Azure portal. 在 Azure 门户中的“数据工厂”页,单击“链接的服务”以启动“链接的服务”页。In the Azure portal, in the Data Factory page, click Linked services to launch the Linked services page. 选择网关以启动“网关”页。Select the gateway to launch the Gateway page. 在“网关”页中,可以查看与网关关联的节点。In the Gateway page, you can see the nodes associated with the gateway. 该页面将允许从网关删除节点。The page lets you delete a node from the gateway.

删除后,在相同的 Azure 门户页中单击“预览版功能”,然后禁用预览版功能。After deleting, click preview features in the same Azure portal page, and disable the preview feature. 已将网关重置为 GA(正式发布)单节点网关。You have reset your gateway to one node GA (general availability) gateway.
