Google Transfer Appliance is a high-capacity storage server that enables enterprises to transport large volumes of data to Google Cloud Storage. The physical device is designed to reduce the lengthy transfer times, and potential security risks, that come with migrating data over the internet and into the public cloud. To use Transfer Appliance, a customer requests the appliance from Google, who then ships it to the customer's location. The customer then transfers their data onto the appliance and ships it back to Google, who uploads that data into its Google Cloud Storage service. After the process is complete, Google wipes the appliance. The Google Transfer Appliance is available in two sizes: 100 TB and 480 TB. Each appliance can potentially store up to 200 TB and 1 PB, respectively, depending on the deduplication and compression ratio of the customer's data. Enterprises can choose between a rackable or standalone appliance. Google recommends that enterprises use Transfer Appliance in cases where it would take them over a week to upload data to the cloud via the internet, or when an enterprise needs to migrate over 60 TB of data. |
