An organization plans to migrate 300 TB of on-premises data to Google Cloud Storage.

Order a Google Cloud Transfer Appliance, copy the data locally over the internal network using NFS or SMB, and ship it to Google for ingestion.: What Transfer Appliance is Transfer Appliance is a high-capacity, ruggedized hardware storage server supplied by Google Cloud that enables organizations to securely migrate large volumes of data (tens to hundreds of terabytes or petabytes) offline when network bandwidth is constrained or migration timelines are tight. How it meets the project requirements Bandwidth calculation: At an outbound network speed of 100 Mbps, transferring data online yields approximately 1.08 TB per day under ideal conditions without network overhead. Uploading 300 TB over a 100 Mbps connection requires roughly 278 days (over 9 months), which severely violates the 21-day timeline. Local transfer speed: Transfer Appliance connects directly to the local data center network via high-speed interfaces (such as 10 GbE / 40 GbE) and supports local protocols like NFS and SMB, allowing data capture at gigabytes per second. Time constraint compliance: The end-to-end turnaround time—including device delivery, local data copying, return shipping, and Google data ingestion—typically takes 1 to 3 weeks, allowing the 300 TB migration to complete comfortably within the 21-day deadline. Key advantages of Transfer Appliance Bypasses internet bandwidth bottlenecks: Eliminates reliance on slow or congested wide-area network (WAN) links. Built-in encryption and security: Employs hardware-level AES-256 encryption managed by customer keys to secure data in transit. Native file share support: Seamlessly mounts to existing enterprise storage via standard NFS, SMB, or CIFS protocols. Automated ingestion: Google technicians upload the encrypted dataset directly into the specified Cloud Storage bucket upon receipt. Why this is optimal When data transfer calculations indicate that an online migration would exceed the required time window—specifically when transfer times stretch into months—offline physical migration with Transfer Appliance is the Google-recommended approach to guarantee timely completion.

What Transfer Appliance is

Transfer Appliance is a high-capacity, ruggedized hardware storage server supplied by Google Cloud that enables organizations to securely migrate large volumes of data (tens to hundreds of terabytes or petabytes) offline when network bandwidth is constrained or migration timelines are tight.

How it meets the project requirements

Bandwidth calculation: At an outbound network speed of 100 Mbps, transferring data online yields approximately 1.08 TB per day under ideal conditions without network overhead. Uploading 300 TB over a 100 Mbps connection requires roughly 278 days (over 9 months), which severely violates the 21-day timeline.
Local transfer speed: Transfer Appliance connects directly to the local data center network via high-speed interfaces (such as 10 GbE / 40 GbE) and supports local protocols like NFS and SMB, allowing data capture at gigabytes per second.
Time constraint compliance: The end-to-end turnaround time—including device delivery, local data copying, return shipping, and Google data ingestion—typically takes 1 to 3 weeks, allowing the 300 TB migration to complete comfortably within the 21-day deadline.

Key advantages of Transfer Appliance

Bypasses internet bandwidth bottlenecks: Eliminates reliance on slow or congested wide-area network (WAN) links.
Built-in encryption and security: Employs hardware-level AES-256 encryption managed by customer keys to secure data in transit.
Native file share support: Seamlessly mounts to existing enterprise storage via standard NFS, SMB, or CIFS protocols.
Automated ingestion: Google technicians upload the encrypted dataset directly into the specified Cloud Storage bucket upon receipt.
