Before adding EBS disks, and creating your storage pools and volumes, there are many considerations specific to creating volumes and pools for EBS disks. Review the AWS EBS considerations found in Amazon EBS RAID Considerations.
How to Add Amazon EBS Disks
- In SoftNAS StorageCenter, choose Disk Devices from the main menu.
- The Disk Devices panel appears.
- From Disk Devices, click on Add Device.
- From Add Device screen, select Amazon EBS Disk.
- Complete the Amazon EBS Disk form as described in the table below.
Add Amazon Disk Reference Table
Use IAM If checked, SoftNAS will use your IAM role and policies to create and add your storage to the SoftNAS instance. If checked, the fields for the AWS Access Key ID and Secret Access Key will be grayed out to prevent confusion.
AWS account credentials
Enter the AWS account credentials used to access Amazon Web Services.
Note: If AWS account credentials are unavailable (grayed out), an Amazon IAM Role was specified at SoftNAS® instance creation. Creating a SoftNAS® IAM user from the Amazon Web Services Dashboard is the recommended approach for a more secure connection to AWS.

EBS Disk Options
Maximum Disk Size:
Must be between 1-1024 GB.
Check this option and provide a Disk Password to encrypt the contents of the EBS disk to ensure its contents cannot be accessed, except via this EBS Disk.
General Purpose SSD:
General Purpose (SSD) volumes offer cost-effective storage that is ideal for a broad range of workloads. These volumes deliver single-digit millisecond latencies, the ability to burst to 3,000 IOPS for extended periods of time, and a base performance of 3 IOPS/GiB. General Purpose (SSD) volumes can range in size from 1 GiB to 1 TiB.
Provisioned IOPS (SSD):
Provisioned IOPS (SSD) volumes are designed to meet the needs of I/O-intensive workloads, particularly database workloads, that are sensitive to storage performance and consistency in random access I/O throughput. Specify an IOPS rate (using the dropdown provided when the option is selected) when the volume is created, and Amazon EBS delivers within 10 percent of the provisioned IOPS performance 99.9 percent of the time over a given year.
Magnetic volumes provide the lowest cost per gigabyte of all Amazon EBS volume types. Magnetic volumes are backed by magnetic drives and are ideal for workloads performing sequential reads, workloads where data is accessed infrequently, and scenarios where the lowest storage cost is important. These volumes deliver approximately 100 IOPS on average, with burst capability of up to hundreds of IOPS, and they can range in size from 1 GiB to 1 TiB. Magnetic volumes can be striped together in a RAID configuration for larger size and greater performance.
- Click on Create SSD Disk.
The EBS Disk is created and automatically partitioned and ready for use.
The next step is to create a Storage Pool which uses the EBS disk.
Note: Ensure sufficient licensed capacity in SoftNAS® to accommodate the amount of storage capacity that will be added.
