Understanding Write-Order-Consistency:
Write-order-consistency ensures that all writes are completed in a specific order to maintain data integrity, particularly important for applications that rely on consistent data states across multiple volumes.
Consistency Groups in PowerStore:
Consistency Groups in Dell PowerStore allow multiple volumes to be managed together as a single entity.
When snapshots are taken of a Consistency Group, all member volumes are captured simultaneously with write-order-consistency, ensuring data integrity across the group.
Other Options:
Volume Groups: Typically used to group volumes for management purposes but do not ensure write-order-consistency for snapshots.
Snapshot Groups: Focus on managing snapshots but without the guaranteed consistency across multiple volumes.
Data Groups: Not a feature in Dell PowerStore specific to this requirement.
Dell Midrange Storage References:
Dell PowerStore documentation provides detailed guidelines on using Consistency Groups for applications requiring write-order-consistent snapshots.
Additional resources from Dell Technologies' support and community forums further validate this feature.
