多种网络连接选项：使用 10Gbps RJ45 接口或 40Gbps QSFP+ 接口，将数据从您的设备快速移动到 Transfer Appliance。
通过多个设备实现扩容：您可以订购多个设备来对转移进行扩容，从而提高转移速度。
全球分布式处理：缩短设备在您与 Google 之间的往返时间，确保数据快速转移到 Cloud Storage。
最少的软件：对于 Linux 和 Apple macOS 系统，使用系统上已安装的常见软件，通过将设备上公开的 NFS 共享装载到工作站将数据直接复制到 Transfer Appliance。对于 Microsoft Windows 系统，请使用 SCP 将数据从工作站直接复制到 Transfer Appliance。

For Transfer Appliance\ncapacities and requirements, refer to the\n[Specifications page](/transfer-appliance/docs/4.0/specifications). \n\nHow it works\n------------\n\nSecurity features\n-----------------\n\nYour data and network security is important. Transfer Appliance helps\nensure that you're connecting a trusted device to your equipment and\nnetwork, and secures your data from end to end so that it is read by people\nyou trust.\n\nTo ensure Transfer Appliance is trusted and safe to connect to your\ndevices, Transfer Appliance offers the following features:\n\n- **Tamper resistant**: Bad actors cannot easily open\n Transfer Appliance's physical case. We also apply\n tamper-evident tags to the shipping case, so that you can visually inspect\n each appliance's integrity prior to opening the package.\n\n- **Ruggedized**: Transfer Appliance's shipping container is\n ruggedized, ensuring your data arrives safely.\n\n- **Trusted Platform Module (TPM) chip**: We validate the TPM's Platform\n Configuration Registers to ensure that the immutable root filesystem and\n software components haven't been tampered with.\n\n- **Hardware attestation**: We use a remote attestation process to validate\n the appliance before you can connect it to your device and copy data to it.\n If anything is amiss, we work with you to quickly send you a new appliance.\n\nTo ensure your data is safe during and after transit,\nTransfer Appliance uses the following features to protect you:\n\n- **AES 256 encryption**: Your data is encrypted with industry-standard\n encryption to keep it safe.\n\n- **Customer-managed encryption keys**: We use encryption keys that you manage\n using Cloud Key Management Service (Cloud KMS), enabling you to control and secure\n your data prior to shipping an appliance back to us.\n\n- **NIST 800-88 compliant data erasure**: We securely erase your data from\n Transfer Appliance after uploading your data to\n Cloud Storage. You can request a wipe certificate to verify that we've\n wiped your data.\n\nFor more information, refer to\n[Security and encryption](/transfer-appliance/docs/4.0/security-and-encryption).\n\nPerformance\n-----------\n\nTo enable you move data quickly and efficiently,\nTransfer Appliance has the following performance features:\n\n- **All SSD drives**: Increased reliability over hard disk drives to ensure\n your transfer is smooth.\n\n- **Multiple network connectivity options**: Quickly move data from your\n devices to Transfer Appliance, using either a 10Gbps RJ45 interface\n or a 40Gbps QSFP+ interface.\n\n- **Scalability with multiple appliances**: You can scale your transfers by\n ordering multiple appliance to increase your transfer speed.\n\n- **Globally distributed processing**: Reduced shipping times to and from\n Google ensures your data transfer to Cloud Storage is quick.\n\n- **Minimal software**: For Linux and Apple macOS systems, copy directly\n to Transfer Appliance by mounting the exposed NFS share on\n the appliance to your workstation, using common software already installed\n on the system. For Microsoft Windows systems, copy directly to\n Transfer Appliance from your workstation using SCP.\n\nOnline capabilities\n-------------------\n\nEnabling online mode allows you to perform online transfers by streaming data\ndirectly to your Cloud Storage bucket after copying it to your appliance.\nOnline transfers offer the following benefits:\n\n- **Quickly transfer data to Cloud Storage with low latency**: Online\n transfers are an accelerated method of transferring your data to\n Cloud Storage, omitting the need to wait for your appliance to be shipped\n back to Google before the data is copied to your destination bucket.\n\n- **Connect to multiple appliances**: Online mode allows parallel connectivity\n to multiple appliances.\n\n- **Cost-effective**: Online capability is offered as a low-cost, fully-managed\n method for transferring your data.\n\n- **Secure connection**: Your data is encrypted during online transfers,\n ensuring end-to-end security. After the transfer is complete, your data is\n removed from the appliance.\n\n- **Easy to enable or disable** : You can toggle between online and offline mode\n using simple commands. For more information on how to enable or disable online\n mode, refer to the\n [Online/offline transfer](/transfer-appliance/docs/4.0/online-transfer) page.\n\nIs Transfer Appliance suitable for me?\n--------------------------------------\n\nTransfer Appliance is a good fit for your data transfer needs if:\n\n- You are an existing Google Cloud customer.\n- Your data resides in locations that Transfer Appliance is [available](#location-availability).\n- It would take more than one week to upload your data over the network.\n\n### Other transfer options\n\nOther Google Cloud transfer options include:\n\n- [Storage Transfer Service](/storage-transfer/docs/overview) to move data to a\n Cloud Storage bucket from other cloud storage providers or from your\n [on-premises](/storage-transfer/docs/key-terms#on-prem) storage.\n\n- [BigQuery Data Transfer Service](/bigquery/transfer) to move data from software as a\n service (SaaS) applications to BigQuery.\n\n- [Transfer service for on-premises data](/storage-transfer/docs/on-prem-overview) to move data from your\n on-premises machines to Cloud Storage.\n\nWhere is Transfer Appliance available?\n--------------------------------------\n\nTransfer Appliance is available in the following locations:\n\nFor a complete list of countries where Transfer Appliance is available, refer to the Order Appliance page on the Google Cloud console. If you don't find your country listed, reach out to Support at data-support@google.com.\n\nData transfer speeds\n--------------------\n\nWith a typical network bandwidth of 100 Mbps, 300 terabytes of data takes about\n9 months to upload. However, with Transfer Appliance, you can\nreceive the appliance and capture 300 terabytes of data in under 25 days. Your\ndata can be accessed in Cloud Storage within another 25 days, all without\nconsuming any outbound network bandwidth.\n\nExample use cases\n-----------------\n\n### Data collection\n\nIf you need to transfer data from researchers, vendors, or other sites to\nGoogle Cloud, Transfer Appliance can move that data for you. Once\ntransferred to [Cloud Storage](/storage) or [BigQuery](/bigquery),\nyour data is accessible via our Dataflow processing service for machine\nlearning projects. Google Cloud Machine Learning Engine is a managed service\nthat enables you to easily build machine learning models, that work on any type\nof data, of any size.\n\n### Data replication\n\nTransfer Appliance can assist you in taking advantage of hybrid\narchitectures, supporting current operations with existing on-premises\ninfrastructure while experimenting with the cloud. By transferring a copy of\nyour data to Google Cloud, you can decommission duplicate datasets, test cloud\ninfrastructure, and expose your data to machine learning and analysis.\n\n### Data migration\n\nOffline data transfer is suited for moving large amounts of existing backup\nimages and archives to Cloud Storage, which can be stored in ultra low-cost,\nhighly-durable, and highly available storage classes such as\n[Archive Storage](/storage/docs/storage-classes#archive). For structured and\nunstructured data sets, whether they are small and frequently accessed or huge\nand rarely referenced, Google offers solutions like Cloud Storage,\nBigQuery, and Dataproc to store and analyze that data.\n\nData handling for the European Union\n------------------------------------\n\nFor customers in the EU, appliances are shipped from Belgium. When\ndata capture is complete, you ship the appliance to Belgium for data upload.\nYour data is then uploaded to a Cloud Storage location in a region\nthat you have specified. If you choose a destination region within the EU, your\ndata never leaves the boundaries of the European Union during any part of the\ndata transfer process.\n\nWhat's next?\n------------\n\n- [Request Transfer Appliance](https://console.cloud.google.com/transfer/appliance).\n- [Learn more about Transfer Appliance pricing](/transfer-appliance/pricing).\n- [Review the procedure for using Transfer Appliance](/transfer-appliance/docs/4.0/procedure-guide)."]]
