Creating Offload Groups

The vStor Group Offloading feature allows you to create an offload group between multiple vStor servers.

Group offloading provides a simple way to set up and manage offloading for multiple volumes. Instead of creating individual offload relationships between volumes on different vStor servers, you can add volumes to a group and efficiently schedule and offload them together.

Creating an Offload Group

Note. The vStor servers must already have partnerships established before creating a group offloading.

To create a new offload group:

1. Select Offload from the sidebar.

2. Click Create group in the Offload Relationships section to open the Create Group dialog.

1. Specify the following information:

   • Name: Enter a name for the offload group.

   • Partner: Select the IP address of the partner vStor server.

   • Replication Bandwidth Settings: Select the replication priority. This setting is only applicable when Bandwidth limit is set in System Settings (see Replication), and it determines how much of the bandwidth is consumed by each task when they coincide.

   • Remote pool: Select the target pool on the partner server. This pool will be used as the target only for volumes without a defined offload relationship.

   • (optional) Select volumes: Select volumes from the dropdown list to add to the group. Only compatible volumes will be listed. If volumes with already defined relationships are selected, their target offload pool will remain unaffected by the selection in the Create Group window.

1. Click Save to create the offload group.

Note. You can only group volumes connected to the same Partner IP address.

The selected volumes will be offloaded as a group according to the configured schedule and settings.

Scheduling Group Offloading

After creating an offload group, you can configure a schedule for offloading the volumes within the group.

To schedule group offloading:

1. In the Offload Relationships section, hover over an offload group and click Schedule.

1. Follow the steps as in Scheduling an Offload.

2. Click Save to save the schedule.

The volumes in the group will now be offloaded according to the configured schedule.

You can also manually trigger offloading for an offload group by hovering over the group and clicking Synchronize.

Additional Group Offloading Options

To use additional options, Hover over an offload group and click More Actions (...). It gives you access to the following options:

• Edit: Modify the group name or volumes in the group.

• Ungroup: Remove the group but keep the offload relationships intact.

• Delete: Delete the group and all offload relationships within it.

vStor CLI for Group Offloading

To create a new offload group using the vStor CLI, use the following command:

vstor offload group create --name <name> --partner_id <partner_id> --bandwidth_priority <priority> --remote_pool_id <pool_id> --local_vol_ids <vol_ids>

To update an existing offload group using the vStor CLI, use the following command:

vstor offload group update --id <id> --name <name> --bandwidth_priority <priority> --remote_pool_id <pool_id> --local_vol_ids <vol_ids>

Tip. For more commands and parameters, use the --help flag at any level, e.g:

vstor offload group --help vstor offload group create --help
