What is the maximum number of SDSs per protection domain of the PowerFlex rack?

Show Suggested Answer Hide Answer
Suggested Answer: D

When migrating a vTree for a snapshot to a different storage pool in PowerFlex, one of the restrictions is that the migration cannot occur between storage pools with different data layouts if multiple volumes are involved in the vTree. This is because the data layout is fundamental to how data is organized and managed within the storage pool, and migrating multiple volumes with different data layouts could lead to inconsistencies and potential data integrity issues.

Here's a more detailed explanation:

Data Layout Compatibility: For a successful migration, the source and target storage pools should have compatible data layouts. Migrating vTrees that span multiple volumes between storage pools with different data layouts is restricted because it could disrupt the organization and accessibility of the data1.

Single Volume Migration: While it is possible to migrate a single volume vTree between storage pools with different data layouts, doing so with multiple volumes in the vTree is not supported due to the complexity and risk involved1.

This restriction ensures that the integrity of the data is maintained during the migration process and that the storage system continues to operate reliably. It is important to consult the PowerFlex documentation, such as the ''Configure and Customize Dell PowerFlex'' guide, for detailed information on supported migration scenarios and restrictions1.

Okay, I've got a strategy here. I'll start by thinking through what a "protection domain" is in the context of the PowerFlex rack, and then I'll try to reason out the maximum number of SDSs that can be supported.

I've got a good strategy here. I'll start by eliminating the options that seem clearly wrong, then focus on the ones that seem more plausible. B and C seem like the most likely correct answers.
