Once FlexFiles Settings have been configured, it is time to configure the volume for transition to the target node. The Lift and Shift Process is broken up into 5 key steps. To begin these steps, select Lift and Shift from the Storage Administration pane.
Step 1 - Naming the Data Flow
Once Lift and Shift is selected, select Create New from the Lift and Shift pane.
Enter a name for the Flow you are creating. Click Next.
Note: In older versions of SoftNAS Cloud, an additional step might be required: selecting the platform. If this appears, you would select the platform you are running: Microsoft Azure, Amazon Web Services, or VMware.
Step 2 - Enter Node information
Enter the IP address, username and password for the target node.
Once the appropriate information is entered, you need to select Verify login to assure credentials entered for the target node are correct. If login is successful, the Next button in the lower right will become active. Select Next and Lift and Shift will begin setting up the communication between the Source and Target.
Note: If the login fails after selecting Next, the credentials for the “cloud connection” needs to be checked.
Note: This process will take several minutes so be patient. If the process takes over 5 minutes without completing, it is a good idea to double check your 9443 and 8081 settings for both the Source and Target and make sure they are correct.
Once the setup of FlexFiles on the Target is complete, and FlexFiles is restarted successfully, you will automatically be transferred to Step 4.
Step 4 - Configure Volumes
Next, you will specify the volumes to be "lifted" as well as the target to which the volumes will be "shifted".
- If the volumes you intend to move are hosted on a separate file server, you will need to specify that fileserver via DNS.
- If you are moving volumes hosted on a fileserver, you will need to specify the protocol they are using - NFS or CIFS. If CIFS is selected, the domain, username and password will need to be provided. These fields will appear upon selecting the CIFS radio button. Click Mount Volumes once the required information is entered.
- If the volumes are hosted on the SoftNAS Cloud instance you are initiating Lift and Shift from (the Source instance), they will appear in "Select Volumes to Lift and Shift". Select the volume or volumes you intend to 'lift'.
- Once the volume is specified, it is time to configure the target volume that will receive the data. Specify the Cloud Disk Type from the available options, based on the target instance and the type of storage that is available and appropriate (ie: Amazon EBS Disk or S3 for AWS, Azure Blob for Azure, etc.)
- Once the Cloud Disk type is specified, select from the options available for that type - in the above example, Amazon EBS Disk was selected. The options available for this selection include General Purpose (SSD), Provisioned IOPS (SSD), Magnetic, Throughput Optimized HDD, and Cold HDD.
- Delete on termination is an option that is unlikely to be used in a Lift and Shift environment - if this option is selected, it means that the volume created will not be persistent - if the host instance is terminated, the volume will be deleted, and therefore unrecoverable.
- Encryption allows you to encrypt the volume to be created.
- RAID Level allows you to select the software RAID level you wish to apply to the pool/volume to be created. It is a good idea to mirror the settings of the source volume. Raid Level will dynamically create the necessary disks to create a pool/volume of the selected RAID level.
- Here you will select the size of the pool to be created. It must be at least large enough to host the volume from the source instance.
- Enter the name of the pool to be created on the target instance.
- You can enable compression for your target volume.
- You can also enable Deduplication.
Once you have selected the desired settings, you can select Create Target Storage to move to Step 5.
You can also use the advanced configuration wizard to configure your target storage. The advanced configuration method allows you more granular control of the pools and volumes created, as well as how they are labelled.
- Select the type of disk you wish to create, based on the target instance type.
- Enter the required account credentials (or storage account credentials for Azure) you want to use.
- Enter in the size of the disk(s) and number you want to create on the Target.
Note: It is recommended you increase the size of the target disk devices by 20% to ensure adequate space for any overhead.
Helpful Hint: Before you select Create, go to the Target and make sure you have enough disk resources available to build the number of drives you have specified.
- After you target disk(s) have been created, select Target Pools to create the pools to use on the target node. Enter the Pool name, then select and add the newly created disks.
- Select Target Volumes to proceed to creating the actual volumes on the Target.
- Enter the Volume name and select the magnifying glass to get a list of the available Storage Pools.
- Enter the type of volume as well as other volume options you may want on the Target.
Select Create to create the Target Volume and Next to proceed to Step 5.
Step 5 - Configure (Map) Source to Target
Having specified the pools and volumes to be shifted, and configured the target node to receive the data, it is now time to verify the operation is properly configured. Simply click Verify to test your configuration.
If properly configured, you will see "passed" in the status column. You can now click Finish. The Lift and Shift configuration should now be complete.
All that remains is to run the operation. Click Verify Config to perform a final validation.
Finally, click Start Data Flow to begin the Lift and Shift operation.
Lift and Shift to a Target configured with HA
A Lift and Shift operation in which the target is an HA pairing is the same process as with a standard create target operation. However, when the Lift and Shift flow is created, the target node selected MUST be the primary node of the HA pair. An error will be received if an attempt is made to configure the secondary node as the target. There are a few things that must be considered as well:
If an HA failure occurs, the Lift and Shift flow will stop. The flow will resume once contact is re-established with the primary node.
If a catastrophic failure occurs on the primary node, it will need to be replaced with a new VM, and the flow will have to be reconfigured and started from scratch. If this occurs, you may want to contact support to determine if the already lifted and shifted data can be recovered, and have the Lift and Shift flow resume from where it left off.
