Q

What is Snowball Edge?

General

AWS Snowball Edge | Storage

A

Snowball Edge is a 100TB data transfer device with on-board storage and compute power for select AWS capabilities. In addition to transferring data to AWS, Snowball Edge can undertake local processing and edge-computing workloads. Features include an S3-compatible end-point on the device, a file interface with NFS support, a cluster mode where multiple Snowball Edge devices can act as a single, scalable, storage and compute pool with increased durability, and the ability to run Lambda functions as data is copied to the device.

Q

How does Snowball Edge work?

General

AWS Snowball Edge | Storage

A

You start by requesting one or more Snowball Edge devices in the AWS Management Console based on how much data you need to transfer or process. The buckets and Lambda functions you select are automatically configured, encrypted and preinstalled on your devices before they are shipped to you. Once a device arrives, connect it to your local network and set the IP address either manually or automatically with DHCP. The same is true for setting up a cluster. Then use the Snowball Edge client software, job manifest, and unlock code to verify the integrity of the Snowball Edge device or cluster, and unlock it for use. The manifest and unlock code are uniquely generated and crypto-logically bound to a designated Snowball Edge to help ensure that both cannot be used with any other devices. Data copied to Snowball Edge is automatically encrypted and stored in the buckets you specify.

All logistics and shipping is done by Amazon so when copying is complete and the device is ready to be returned, the E Ink shipping label will automatically update the return address to help ensure that the Snowball Edge device is delivered to the correct AWS facility. Once the device ships, you can receive tracking status via messages sent by Amazon Simple Notification Service (Amazon SNS), generated texts and emails, or directly from the console.

All of the management for your Snowball Edge resources can be performed in the AWS management console and these operations require no on-site system engineers.

Q

Who should use Snowball Edge?

General

AWS Snowball Edge | Storage

A

Snowball Edge is the optimal data transfer choice if you need to securely and quickly transfer terabytes to petabytes of data to AWS. You can use Snowball Edge if you have a large backlog of data to transfer or if you frequently collect data that needs to be transferred to AWS and your storage is in an area where high-bandwidth Internet connections are not available or cost-prohibitive. You can also use Snowball Edge to run edge computing workloads such as performing local analysis of your data using Lambda functions, backed by a Snowball Edge cluster with increased durability and an S3-compatible endpoint. You can streamline it into existing workflows leveraging built-in capabilities such as the NFS file interface and migrate files to the device while maintaining file metadata. Snowball Edge can operate in remote locations or harsh operating environments, such as factory floors, oil & gas rigs, mining sites, hospitals, and on moving vehicles. Snowball Edge is pre-configured and does not have to be connected to the internet, so processing and data collection can take place within isolated operating environments. Snowball Edge allows you to run the same software at the edge and access select AWS capabilities as you do when you have full connectivity to AWS.

Q

How does Snowball Edge help digitally secure my data?

Security

AWS Snowball Edge | Storage

A

Snowball Edge is designed with security in mind for the most sensitive data. All data is encrypted by keys provided by you through AWS Key Management Service (KMS). The keys are not permanently stored on the device and are erased after loss of power. Applications and Lambda functions run in a physically isolated environment and do not have access to storage. Lastly, after your data has been transferred to AWS, your data is erased from the device using standards defined by National Institute of Standards and Technology. Snowball Edge devices are hardened against attack and all configuration files are encrypted and signed with keys that are never present on the device.

Q

How do I use the file interface on Snowball Edge?

File Interface

AWS Snowball Edge | Storage

A

Once the Snowball Edge arrives at your site and has been unlocked, each of the S3 buckets is made available to your applications as an NFS export visible on the network to which the Snowball Edge is connected. You can use the local LCD display on the Snowball Edge to disable/enable the file interface. You can mount these NFS exports on your server, and your applications can read and write files as they would any other network shared file system. You can monitor the file interface status, and open a support channel through the LCD display.

Q

What use cases does the file interface on Snowball Edge enable?

File Interface

AWS Snowball Edge | Storage

A

The file interface enables multiple use cases. It lets you ingest existing files into Amazon S3 as objects using a common file protocol (NFS), and preserves associated file metadata as object metadata. This offline bulk data transfer enables you to seed file data into S3, and use it for in-cloud workloads, such as Big Data processing. Alternatively, the transferred file data can be accessed from your sites for hybrid applications or workflows by using AWS Storage Gateway.

Q

Can I use both the file interface and the Amazon S3 Adapter for Snowball to write to a bucket on an AWS Snowball Edge appliance?

File Interface

AWS Snowball Edge | Storage

A

We recommend against writing to buckets on an AWS Snowball Edge appliance both directly and through the file interface. If you directly overwrite or update an object previously written by the file interface, it will result in undefined behavior when the object is accessed through the file interface. Concurrent modification of the same object (e.g. via the file interface and the Amazon S3 Adapter for Snowball) will lead to unpredictable results.

34
Q

Should I use the file interface to load data into the Snowball Edge or the Amazon S3 Adapter for Snowball?

File Interface

AWS Snowball Edge | Storage

A

You can use file interface when your existing workflow is file-based or you want to access objects in S3 as files using standard filesystem operations. You can use the Amazon S3 Adapter for Snowball when your application doesn’t require file system operations and can manage data transfer directly.

35
Q

How does the file interface on Snowball Edge compare with the AWS Storage Gateway?

File Interface

AWS Snowball Edge | Storage

A

The file interface on Snowball Edge enables you to easily ingest data into S3 in an “off-line” mode. This is useful when you need to import sets of files that don’t need to be immediately available in S3, or from locations with insufficient bandwidth to transfer the data over the network.

AWS Storage Gateway enables you to put file data into S3 over the Internet or AWS Direct Connect, making your uploaded files instantly available.

36
Q

Can I access files migrated via the file interface on Snowball Edge from Amazon EFS?

Clustering

AWS Snowball Edge | Storage

A

No. Files migrated via the file interface on Snowball Edge can be accessed directly as objects in S3 or as files through the AWS Storage Gateway.

Once the Snowball Edge devices have all arrived at your location, you need to power them on, connect them to the same network, download the manifest file and unlock code, download the Snowball client, and “unlock” the cluster.

47
Q

Can I issue management commands and reads/writes to any node in a cluster?

Clustering

AWS Snowball Edge | Storage

A

Yes. Each Snowball Edge node in the cluster is capable of both reads and writes using S3 commands. You can also mount each node separately and perform simultaneous reads and writes across the cluster. Snowball Edge commands can be used across any node of a cluster to perform management functions like unlock, describe, etc.

48
Q

How do I unlock my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

Before starting the unlock process, please ensure that you have at least N-2 nodes of your cluster available to you, where N is the maximum number of nodes in the cluster.

Clustering

AWS Snowball Edge | Storage

A

No. You can unlock all nodes in a cluster by issuing the “unlock-cluster” command to a single node in your cluster.

50
Q

Can I unlock certain nodes of my Snowball Edge cluster before I receive all devices or do I need to wait until I have all devices in my possession?

Clustering

AWS Snowball Edge | Storage

A

We do not recommend you start your Snowball Edge cluster with less than the number of nodes that the cluster job is provisioned with since you may, or may not, be able to read and/or write durably to the cluster depending on the number of nodes.

51
Q

How do I know what the total number of nodes are in my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

After configuring your client, you can run a simple command to learn more about the number of nodes that are available in your Snowball Edge cluster.

Cluster Association Status: Indicates whether a device is associated with a cluster.

Extending Nodes in an AWS Snowball Edge Cluster

53
Q

Is my Snowball Edge cluster expandable in size by adding nodes?

Clustering

AWS Snowball Edge | Storage

A

You can add a new node to your Snowball Edge cluster if you have removed an unhealthy node from the cluster, or if you are adding another node for increased local storage. To add a new node, you first need to order a replacement. Ordering a replacement node can be done from the console, from the AWS CLI, or from one of the AWS SDKs.

Replacing Nodes in an AWS Snowball Edge Cluster

54
Q

Can I remove a node from my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

You can remove a node from your Snowball Edge cluster if you intend to replace it. You may want to do this if one of your nodes is unhealthy, is not powering on, or is defective. To remove a node, you can power it off and use a simple disassociate command.

55
Q

How do I replace a node in my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

To order a replacement node in your Snowball Edge cluster, you can go to the AWS Console page, and order a replacement device. Once you receive the replacement device, you need to follow a few steps:

Remove the unhealthy device from the cluster by powering it off and use the “disassociate-device” command.

Plug-in the replacement Snowball Edge device and wait about 10 minutes for it to boot. If DHCP is being used then the device will obtain an IP address automatically. If you are using a static IP address then you will need to manually assign an IP address.

Add the replacement Snowball Edge device and “associate” it.

56
Q

What happens if I remove more than one Snowball Edge device from my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

You cannot remove more than one Snowball Edge device from a Snowball Edge cluster at any time.

57
Q

Can I continue to use the Snowball Edge cluster while I am replacing a Snowball Edge device?

Clustering

AWS Snowball Edge | Storage

A

Yes. You can continue to use the Snowball Edge cluster even when you are replacing a Snowball Edge device. Until all the nodes are ASSOCIATED and REACHABLE, the cluster will run in a reduced durability mode.

58
Q

What will happen to stored data once I replace a node from my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

Once you replace a node, the Snowball Edge cluster will repartition the data amongst the remaining nodes so that it can still be used as durable storage.

59
Q

Can I choose different job settings (Address, Shipping speed, Lambda functions, IAM roles, KMS keys, SNS notifications) in my replacement node than what was set when I ordered the Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

No. Each replacement node is pre-configured to use the same job configurations that came with the Snowball Edge cluster.

60
Q

Can I choose a different Lambda function in my replacement node?

Clustering

AWS Snowball Edge | Storage

A

Yes. You can choose a different Lambda function as long as it uses the same S3 bucket that was originally configured with the Snowball Edge cluster.

61
Q

Can I use the same Snowball Edge cluster manifest key and unlock code as before after ordering a replacement node?

Clustering

AWS Snowball Edge | Storage

A

No. A new cluster manifest and unlock code is generated after your order of a replacement device which must be used with any future operations of the Snowball Edge cluster.

AWS Snowball Edge Cluster Management

62
Q

What happens if one of my nodes is not available?

Clustering

AWS Snowball Edge | Storage

A

You can continue to use the Snowball Edge cluster even if it runs in a reduced durability level. Immediately order a replacement Snowball Edge device so that you can replace this node with a newer device.

63
Q

What happens if two of my nodes are not available?

Clustering

AWS Snowball Edge | Storage

A

You can continue to use the Snowball Edge cluster but note that it will be running in a read-only mode and existing data on the cluster is at risk. Immediately order two replacement devices so that you can replace these nodes with newer Snowball Edge devices.

64
Q

What happens if three or more of my nodes are not available?

Clustering

AWS Snowball Edge | Storage

A

You cannot use the Snowball Edge cluster anymore and existing data on the cluster is at risk. Contact AWS support immediately if three or more Snowball Edge devices are non-functional.

65
Q

How long can I keep a Snowball Edge cluster on premise at my location?

Clustering

AWS Snowball Edge | Storage

A

The maximum duration a Snowball Edge cluster can be kept on premise at your location is 360 days from the day the order was created. After that, the certificates in the cluster expires and either all the Snowball Edge devices in the cluster must be returned or you should order new devices.

66
Q

Can I pre-order replacement devices for my Snowball Edge cluster?

Clustering

AWS Snowball Edge | Storage

A

Yes. To pre-order replacement devices, you need to create a Snowball Edge cluster job and then create a job to order replacement Snowball Edge devices. The replacement devices do not need to be connected to the original Snowball Edge cluster until one of the devices is unhealthy. Once a Snowball Edge device is unhealthy, you can remove the device and then add the replacement device.

Ingesting Data with AWS Snowball Edge Clustering

67
Q

Can a Snowball Edge cluster come preloaded with data from an existing S3 bucket?

Clustering

AWS Snowball Edge | Storage

A

No. However, you can place an order for two Snowball jobs – one cluster job and one export job. The Snowball Edge cluster will come empty from AWS but the export job can be a Snowball (or a Snowball Edge) device that can be used to import data into the Snowball Edge cluster.

Q

Can I ingest data from the entire Snowball Edge cluster back to AWS using individual nodes of my cluster?

Clustering

AWS Snowball Edge | Storage

A

No. A Snowball Edge cluster can only be used for on-premise storage and compute. It cannot be used to import data into AWS. To import data from your cluster, you will need to order additional AWS Snowball (or AWS Snowball Edge) devices and then connect them to the same network as the Snowball Edge cluster and transfer your data from the cluster. Depending on the total amount of data used in the cluster, you may have to order multiple import devices to ship the data back to AWS.

69
Q

When writing data into a cluster, does the network throughput of data transfer increase depending on the number of nodes?

Clustering

AWS Snowball Edge | Storage

A

Yes. The read and write throughput can be higher if you read and write from several devices in parallel.

Q

Does compute capacity scale as I scale my cluster?

Clustering

AWS Snowball Edge | Storage

A

Yes. With more devices, you increase the compute capacity of your cluster.

71
Q

Can I update my Lambda function in my Snowball Edge cluster while it is on premise?

AWS Greengrass

AWS Snowball Edge | Storage

A

No. You cannot update your Lambda function on premise.

72
Q

What is AWS Greengrass?

AWS Greengrass

AWS Snowball Edge | Storage

A

Snowball Edge comes with an embedded version of AWS Greengrass which allows you to execute Python-language AWS Lambda functions in response to S3 PUT object events.

73
Q

What AWS Greengrass features are available on Snowball Edge?

AWS Greengrass

AWS Snowball Edge | Storage

A

Greengrass Core running on Snowball Edge enables you to deploy Python-based Lambda functions to Snowball Edge devices and trigger those Lambdas through MQTT messages. When you create a job for a Snowball Edge with at least one Lambda function pre-loaded, the Snowball Edge is provisioned as a Greengrass Core device by default. Whenever the Snowball Edge is connected to the internet, you can update, add, or remove Lambda functions on the device through the Greengrass console. You can even host Lambda functions that are triggered by MQTT messages other than an S3 PUT. Additionally, you can also update the associated Greengrass group in the Greengrass console and use the device in your group as any other Greengrass Core device.

74
Q

What are some possible use cases for Greengrass on Snowball Edge?

AWS Greengrass

AWS Snowball Edge | Storage

A

Using Greengrass Core on Snowball Edge, you can write custom Lambda functions to provide local processing or pre-processing of data as it is written to the Snowball Edge device via S3 PUT operations and the S3-compatible endpoint available. You can also use the Snowball Edge as the core of your Greengrass group of IoT things. This allows you to do things like collect and analyze sensor data streams or compress images in-real time.

75
Q

How do I use Greengrass on Snowball Edge?

AWS Greengrass

AWS Snowball Edge | Storage

A

Using the AWS Snowball Management Console or the Job Management API, you can map new or existing Lambda functions to pre-configured S3 buckets on a Snowball Edge device before it is shipped to you. Once the device arrives, unlock it and connect it to the internet so Greengrass in the cloud can send the Snowball Edge the certificates it needs to operate as the core of your Greengrass group.

76
Q

What happens if I use AWS Greengrass on a Snowball Edge cluster?

AWS Greengrass

AWS Snowball Edge | Storage

A

You can use Greengrass on a Snowball Edge cluster just as you would with a single Snowball Edge, with each cluster node being its own unique AWS Greengrass core device.

77
Q

How many Lambda functions can there be for each job?

AWS Greengrass

AWS Snowball Edge | Storage

A

At job creation, each Lambda function can be associated with a single S3 bucket on the Snowball Edge. Once you’ve received the device, unlocked it, and connected it to the internet, you can add, remove, or update Lambda functions as you see fit. If you allocated 128 MB of memory to each of your functions, you could have up to 7 Lambda functions at a time.

78
Q

Can I use Greengrass on Snowball Edge from any AWS Region?

Billing

AWS Snowball Edge | Storage

A

Currently, you must use Greengrass on a Snowball Edge in the regions are supported by the Greengrass service. For a list of Greengrass supported regions, see the Region Table. In regions that only support AWS Snowball Edge and not AWS Greengrass, you can still create jobs for Snowball Edge devices, however they won’t have access to the compute functionality.

79
Q

How much does it cost to use Snowball Edge?

Billing

AWS Snowball Edge | Storage

A

Each Snowball Edge job costs a flat fee of $300 for device handling and operations at AWS data centers. The $300 job fee includes 10 day of use at your site. The day that the device is received and the day that the device is shipped are not counted towards these 10 days. Beyond that, a Snowball Edge costs $30/day for each extra day that it is at your site. Data transferred into AWS does not incur any data transfer fees, and Standard Amazon S3 pricing applies for data stored. Exporting data starts at $0.03/GB. In addition, shipping charges are calculated based on standard carrier rates for the shipping location and shipping option (e.g. 2-day, overnight) you choose. The default shipping option is 2-day.

Pricing Example:

The pricing example below illustrates what you can expect to pay for a 90TB data transfer into AWS using a single 100TB Snowball Edge device, where you kept the device for a total of 15 days (received the device on day 1 and returned the device on day 15).

The day the device is received and the day the device is shipped back to AWS are considered shipping days, and are not counted toward the 10 free days in this case. This means you had the device onsite for a total of 13 days, and 10 out of those days are free. Therefore you used 3 extra days to transfer your data.

Service fee: $300

Daily charges (3 days x $30/day): $90

Shipping charges: vary by distance

Data transfer cost: $0

Q

Am I charged for Amazon S3 usage if I use the S3-compatible endpoint on Snowball Edge?

Billing

AWS Snowball Edge | Storage

A

No, you don’t incur additional charges for using the S3-compatible endpoint on Snowball Edge. If your Snowball Edge transfers data into Amazon S3, standard S3 request and storage charges will apply.
