Answer:

"You can use describe-device command from the Snowball client to monitor how much block storage is been used on the device. When you create a volume, all of the storage capacity requested is allocated to it based on the available capacity." Question 2: "Q: How long can I have a Snowball Edge for a specific job?"

Answer:

"Snowball Edge devices must be returned within 360 days of the Snowball Edge's preparation." Question 3: "Q: How do I launch an instance manually?"

Answer:

"Each AMI has an AMI ID associated with it. You can use run-instance command to start the instance by providing this ID. Running this command returns an instance-id value that can be used to manage this instance." Question 4: "Q: How do I get started with block storage on Snowball Edge?"

Answer:

"By default, all Snowball Edge devices are now shipped with the block storage feature. Once you unlock the device you can use AWS CLI or SDK to create volumes and attach them to an Amazon EC2 instance. You can attach multiple volumes to each EC2 instance, however, a single volume can only be

attached to a single instance at any time." Question 5: "Q: How are my AMIs protected while in transit?"

Answer:

"Snowball Edge encrypts all data, including AMIs, with 256-bit encryption. You manage your encryption keys by using the AWS Key Management Service (KMS). Your keys are never stored on the device and you need both the keys and an unlock code to use the device on-premises. In addition to using a tamper-evident enclosure, Snowball Edge uses industry-standard Trusted Platform Modules (TPM) designed to detect any unauthorized modifications to the hardware, firmware, or software. AWS visually and cryptographically inspects every device for any signs of tampering." Question 6: "Q: Which Amazon Machine Images can I use on Snowball Edge to utilize block storage?"

Answer:

"Any Amazon Machine Image (AMI) running on Snowball Edge can access up to 10 block storage volumes at once. Generic AMIs provided by AWS and custom AMIs can access any block storage volume. There are no special requirements to make the block storage volumes work. However, certain operating systems perform better with specific drivers. Please see Snowball Edge's technical documentation for details." Question 7: "Q: How long does it take to transfer my data?"

Answer:

"Data transfer speed is affected by a number of factors including local network speed, file size, and the speed at which data can be read from your local servers. The end-to-end time to transfer up to 80 TB of data into AWS with Snowball Edge is approximately one week, including the usual shipping and handling time in AWS data centers." Question 8: "Q: In what regions are Snowball Edge available?"

Answer:

"Check the Regional Service Availability pages for the latest information." Question 9: "Q: What network interfaces does Snowball Edge support?"

Answer:

"Some Snowball Edge Storage Optimized devices - used for compute jobs currently - include a 10GBase-T network connection, 10/25Gb SFP28 and 40Gb QSFP+ copper, and optical networking for fast data transfer rates.Some Snowball Edge Storage Optimized devices - used for data transfer jobs currently - include a 10GBase-T network connection, 10/25Gb SFP28 and 100Gb QSFP+ copper.The Snowball Edge Compute Optimized includes a 10GBase-T network connection, 10/25Gb SFP28 and 100Gb QSFP+ copper, for running latency-sensitive applications in disconnected environments."

Question 10: "Q: Can I install more than one instance on a device?"

Answer:

"Yes. You can run multiple instances on a device as long as the total resources used across all instances are within the limits for your Snowball Edge device." Question 11: "Q: What happened with the original 50 TB and 80 TB AWS Snowball devices?"

Answer:

"The original Snowball devices were transitioned out of service and Snowball Edge Storage Optimized are now the primary devices used for data transfer." Question 12: "Q: Are the volumes encrypted by default?"

Answer:

"Snowball Edge is designed with security in mind for the most sensitive data. All data written into block volumes is encrypted by keys provided by you through AWS Key Management Service (KMS). All volumes are encrypted using the same keys selected during Snowball Edge job creation. The keys are not permanently stored on the device and are erased after loss of power." Question 13: "Q: Is there a way to easily track my data transfer jobs?"

Answer:

"Snowball Edge uses an innovative, E Ink shipping label designed to ensure the device is automatically sent to the correct AWS facility. When you have completed your data transfer job, you can track it by using Amazon SNS generated text messages or emails, and the console." Question 14: "Q: When can I delete the data on my disk(s) after I've copied the data onto Snowball Edge and shipped the Snowball Edge back to AWS?"

Answer:

"Wait to confirm that the Snowball Edge has been received by AWS and your data has successfully been transferred into appropriate S3 buckets prior to you deleting any data on your disk(s). While AWS verifies the integrity of files copied to Snowball Edge during the S3 transfer, it is your responsibility to verify the integrity of data before deleting it from your disk(s). AWS is not liable for any lost or corrupted data during copy or transit." Question 15: "Q: How do I transfer my data to the Snowball Edge?"

Answer:

"After you have connected and activated the Snowball Edge, you can transfer data from local sources to the device through the S3-compatible endpoint or the NFS file interface, both available on the device.You can also use the Snowball client to copy data. To learn more, please refer to the Snowball Edge documentation."

Question 16: "Q: How do I terminate an existing instance?"

Answer:

"You can terminate a running instance using the terminate-instance command." Question 17: "Q: Can a Snowball Edge be shipped to an alternate AWS region?"

Answer:

"No. Snowball Edge devices are designed to be requested and used within a single AWS region. It may not be requested from one region and returned to another. Snowball Edge devices used for imports or exports from an AWS region in the EU may be used with any of the 28 EU countries. Check the Regional Service Availability pages for the latest information." Question 18: "Q: How is my data secured when I use the S3 Adapter?"

Answer:

"The S3 Adapter writes data using the same advanced encryption mechanism that the Snowball Client provides." Question 19: "Q: What is the difference between the Snowball Edge Storage Optimized and Snowball Edge Compute Optimized options?"

Answer:

"Snowball Edge Storage Optimized is the optimal choice if you need to securely and quickly transfer dozens of terabytes to petabytes of data to AWS. It is also a good fit for running general purpose analysis such as IoT data aggregation and transformation. It provides up to 80 TB of usable HDD storage, 40 vCPUs, 1 TB of SATA SSD storage, and up to 40 Gb network connectivity to address large scale data transfer and pre-processing use cases. We recommend using Snowball Edge Compute Optimized for use cases that require access to powerful compute and high-speed storage for data processing before transferring it into AWS. It features 52 vCPUs, 7.68 TB of NVMe SSD, and up to 100 Gb networking to run applications such as high-resolution video processing, advanced IoT data analytics, and real-time optimization of machine learning models in environments with limited connectivity. For more details, see the documentation." Question 20: "Q: How can I use the GPU with AWS Snowball Edge's SBE instances?"

Answer:

"The GPU option on AWS Snowball Edge Compute Optimized comes with SBE-G instances that can take advantage of the onboard GPU for accelerating the application performance. After receiving the device, select the option to use the SBE-G instance in order to use the on-board GPU with your application."
