Amazon Elastic Block Store (Amazon EBS) provides persistent, block-level storage volumes for use with Amazon EC2 instances in the AWS SoftNAS®. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect from component failure, offering high availability and durability. Amazon EBS and Buurst's SoftNAS® provide access to store and retrieve any amount of data, at any time, from anywhere on the web. It gives anyone access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to customers.

As an example: For 1 TB of usable storage with RAID Redundancy for increased performance and data redundancy, one potential configuration could be:

  • Two 1 TB EBS volumes, configured as RAID 1 mirrors
  • Five 250 GB EBS volumes, configured as RAID 5 (four data, single parity)
  • Seven 250 GB EBS volumes, configured as RAID 6 with a spare (four data, dual parity, one spare)

S3 Cloud Disks for Cloud Storage

Use S3 Cloud Disks to manage up to 4 petabytes of Amazon S3 cloud storage per device. For more information on Cloud Disks, refer to the SoftNAS®S3 Disk Overview section of this guide.

Instance Tags and Key Pairs secure data and verify ownership. Properly set up, these layers of validation protect EC2 Instances from accidental or unauthorized users.

Status Checks & Alarms

Status Checking

In order to know that instance is successfully launched, check its status.

  1. Click Instances in the left panel.
    All the instances related to the specific region will be displayed.
  2. When SoftNAS® is fully booted and is ready for initial configuration and use, the Status Checks column will show a green checkmark with the message that 2/2 checks passed: 

  3. At this point, SoftNAS® instance is operational. 

Status Check Monitoring

Set CloudWatch alarms in order to be notified automatically whenever the metric data reaches a pre-defined level. 

Create a status check alarm

  1. On the EC2 Dashboard, click the Instances option in the left panel.
  2. Select the instance to which to add CloudWatch alarm.
  3. Navigate to the Status Checks tab.

    The Status Checks tab displays the information on the system status checks and instance status checks.

Status Check Alarm

  1. Click Create Status Check Alarm. This will prompt the Create Alarm dialog.

  3. Click Create Topic to specify email addresses for all contacts involved. If only the admin needs to be notified, keep the default choice NotifyMe.

  4. Check the box behind the Take the Action field to initiate the action to be taken in case of the metric reaching a certain level. Also check the box for the type of the action to be initiated as Stop or Terminate this instance. 
  5. Select the condition for defining the required metric from the Whenever drop down list and then from the description drop down list.

  6. The Is field is static at the setting Failing.

  7. Continue the condition for the number of executions for a period.
