- Login to the source (primary) SoftNAS Cloud® Instance.
After login, to add storage, select Add Storage Devices from the Getting Started Checklist, then click Configure Now, or select Disk Devices from the Storage Administration pane.
The Disk Devices tab will open. Click Add Device.
Important: You may notice a disk on your instance labelled ‘Azure Ephemeral Disk’. This is NOT a disk to be used as storage. This disk is used for caching to improve performance.
4. From the Add Disk Device wizard, select the second option, Microsoft Cloud Disk Extender. Click Next.
Provide the service administration account created earlier, to provide access to both the subscription and the storage accounts within the resource group.
Note: If your storage account is a Premium storage account, your disk size selections will be limited to 128GB, 512GB, and 1023 GB. If standard, you will be able to type any size.
Click Create Disk.
Note: SoftNAS displays "Creating..." in the Device Usage column until the Adding Disk process is complete. The process is complete when Device Usage reads 'Available to Assign'.
It is very simple to add a new disk to your SoftNAS instance using the SoftNAS UI. You can now use your newly added disks to create pools and volumes.
Click Create to set up your storage pool.
Upon clicking Create, the The Add Storage Pool dialog will be displayed.
- Standard - If Standard is selected, our patented original SNAP HA™ methodology will be implemented, replicating your block storage across two nodes, with minute by minute updates to ensure parity.
- Shared Storage - If Shared Storage is selected, SNAP HA will initiate a Dual Controller HA™ configuration, which will instead propagate the configuration files of your storage pool to both nodes (each acting as a controller in this scenario) in the HA pairing, allowing the shared storage pool to be nearly immediately imported in the event of primary node failure.
Click Next to begin creating your pool via the Create a New Storage Pool dialog box.
Note: Regardless of the option selected here, the process for configuring High Availability with SNAP HA™ remains unchanged. Dual Controller HA™ is a simple add-on to SNAP HA™. SNAP HA™ will recognize automatically which method to use based on the selection made above, and will configure high availability according to the storage pool settings. Each instance can support both standard SNAP HA™ and Dual Controller HA™ configurations in a mixed environment.
Upon clicking Next, the Create a New Storage Pool wizard wizard will open. Fill in the required information based on the directions to follow:
- Provide a unique alphanumeric name for the pool.
- Determine software RAID level. If not using software RAID for your POC (or if this were a VMware deployment in which hardware RAID was being used) you would select select No Raid, JBOD. For this deployment , we will be using RAID 1/10 also referred to as , striped mirrors.
- Select the number of disks required for your RAID selection. As we selected RAID 1/10 in the step example above, this will require 2 disks. Remember, do NOT use the ephemeral storage disk. Refer to Disk Devices if you are not sure which disk this is.
- Note: If another selection is made, be sure to provide an adequate number of disks for your RAID selection. See SoftNAS’ Software RAID considerations for more detail.
(Optional) Check the box for Forced Creation if you wish to overwrite any pre-existing pools.
- (Optional) SoftNAS supports LUKS encryption, allowing you to establish additional security for your storage. Check the box if you wish LUKS encryption to be applied, and supply a username and password.
- Sync Mode allows you to change synchronization settings for your data. This is an advanced setting. Altering this setting can change performance for better or worse, and can also compromise data security, so it improve performance byThis is an advanced setting and should not be altered without full understanding of the consequences. See valid reason. See Working with Storage Pools for for more information on Sync Mode.
Once settings have been chosen, click click Create. In a few short moments, the storage pool will generate. Be sure to make note of the selections made, as you will repeat this process on the second instance.
