什么是 Data Box Gateway?What is Azure Data Box Gateway?

Azure Data Box Gateway 是一种可以将数据无缝地发送到 Azure 的存储解决方案。Azure Data Box Gateway is a storage solution that enables you to seamlessly send data to Azure. 本文概述了 Azure Data Box Gateway 解决方案、优势、关键功能以及可以部署此设备的场景。This article provides you an overview of the Azure Data Box Gateway solution, benefits, key capabilities, and the scenarios where you can deploy this device.

Data Box Gateway 是一种虚拟设备,基于在虚拟化环境或虚拟机监控程序中预配的虚拟机。Data Box Gateway is a virtual device based on a virtual machine provisioned in your virtualized environment or hypervisor. 该虚拟设备驻留在本地,可以使用 NFS 和 SMB 协议将数据写入其中。The virtual device resides in your premises and you write data to it using the NFS and SMB protocols. 然后,设备会将你的数据传输到 Azure 块 blob、页 blob 或 Azure 文件。The device then transfers your data to Azure block blob, page blob, or Azure Files.

用例Use cases

可利用 Data Box Gateway 将数据传输到云,例如云存档、灾难恢复,或根据需要以云规模处理数据。Data Box Gateway can be leveraged for transferring data to the cloud such as cloud archival, disaster recovery, or if there is a need to process your data at cloud scale. 下面是可以使用 Data Box Gateway 来传输数据的各种场景。Here are the various scenarios where Data Box Gateway can be used for data transfer.

  • 云存档 - 使用 Data Box Gateway 以安全有效的方式将数百 TB 的数据复制到 Azure 存储。Cloud archival - Copy hundreds of TBs of data to Azure storage using Data Box Gateway in a secure and efficient manner. 对于存档场景,可以一次性或持续地引入数据。The data can be ingested one time or an ongoing basis for archival scenarios.

  • 持续数据引入 - 无论数据大小如何,都能够将数据持续引入到设备中,以复制到云端。Continuous data ingestion - Continuously ingest data into the device to copy to the cloud, regardless of the data size. 在将数据写入网关设备时,设备会将数据上传到 Azure 存储。As the data is written to the gateway device, the device uploads the data to Azure Storage.

  • 初始批量传输后进行增量传输 - Data Box 用于在脱机模式下进行批量传输(初始播种),Data Box Gateway 用于在网络上进行增量传输(持续馈送)。Initial bulk transfer followed by incremental transfer - Use Data Box for the bulk transfer in an offline mode (initial seed) and Data Box Gateway for incremental transfers (ongoing feed) over the network.

优点Benefits

Data Box Gateway 具有以下优势:Data Box Gateway has the following benefits:

  • 轻松传输数据 - 可以轻松地将数据移入和移出 Azure 存储,就像使用本地网络共享一样简单。Easy data transfer- Makes it easy to move data in and out of Azure storage as easy as working with a local network share.

  • 高性能 - 通过与 Azure 之间的高性能传输,避免了网络数据传输的麻烦。High performance - Takes the hassle out of network data transport with high-performance transfers to and from Azure.

  • 营业时间的快速访问和高数据引入率 - Data Box Gateway 有一个本地缓存,可以在预配虚拟设备时将其定义为本地容量大小。Fast access and high data ingestion rates during business hours - Data Box Gateway has a local cache that you define as the local capacity size when the virtual device is provisioned. 数据磁盘大小应该按虚拟设备最低要求进行指定。The data disk size should be specified as per the virtual device minimum requirements. 本地缓存具有以下优势:The local cache provides the following benefits:

    • 可以通过本地缓存高速引入时间。The local cache allows data ingestion at a high rate. 在高峰营业时间引入大量数据时,可以由缓存来存储该数据并将其上传到云。When high amount of data is ingested during peak business hours, the cache can hold the data and upload it to the cloud.
    • 可以通过本地缓存进行快速读取访问,直至达到特定的阈值。The local cache allows fast read access until a certain threshold. 在设备达到 50-60% 的容量之前,从设备进行的所有读取都是通过缓存来访问的,因此速度更快。Until the device is 50-60% full, all the reads from the device are accessed from the cache making them faster. 在设备上使用的空间超出此阈值后,设备就会开始删除本地文件。Once the used space on the device goes above this threshold, then the device starts to remove local files.
  • 带宽用量受限 - 即使在营业高峰期网络用量受限,也能将数据写入 Azure。Limited bandwidth usage - Data can be written to Azure even when the network is throttled to limit usage during peak business hours.
