HP0-J73 · Question #314
Your customer has an HP MSA P2000 G3 with 48 x 600GB LFF SAS drives. The customer asks you for an upgrade path to the new HP MSA 2040 Storage. What is the recommended upgrade path?
The correct answer is B. Use HP Peer Motion data on the existing HP MSA P2000 G3 and tier it to a new MSA 2040.. HP Peer Motion is the recommended upgrade path from the MSA P2000 G3 to the MSA 2040 because it enables non-disruptive, online data migration between the two arrays.

Why each option
HP Peer Motion is the recommended upgrade path from the MSA P2000 G3 to the MSA 2040 because it enables non-disruptive, online data migration between the two arrays.
The HP MSA P2000 G3 and MSA 2040 use incompatible controller architectures and form factors, so a data-in-place controller swap is not a supported upgrade option.
HP Peer Motion is a built-in MSA feature that allows data to be moved online and non-disruptively between HP MSA arrays, enabling the customer to migrate workloads from the P2000 G3 to the new MSA 2040 without application downtime. It leverages the existing 600GB SAS drives' data in place during the transition and is the HP-recommended method for migrating between MSA generations. This approach minimizes risk and business disruption compared to any offline migration method.
Purchasing a new MSA 2040 and performing a manual data migration requires scheduled downtime and does not leverage HP's built-in non-disruptive migration tools, making it a less efficient and riskier path.
Repurposing P2000 G3 disks in a new MSA 2040 chassis is not a documented or supported upgrade procedure and bypasses the data integrity protections that a proper migration process provides.
