HPE ASE HPE0-J68 HP Study Notes

When upgrading from an MSA 2040 to an MSA 2050, the customer can physically move the existing SFF drives to the new MSA 2050 system. However, both systems need to be offline during the process to ensure data integrity and a smooth migration. This approach is efficient for customers using virtual pools, as it allows them to transition to the new hardware without complex data migration processes.

When proposing a Primera array and ensuring high availability with an existing HPE 3PAR array, there are specific RMC (Recovery Manager Central) Peer Copy prerequisites that need to be addressed:

Check that the 3PAR OS version is supported (Option D): It is crucial to verify that the HPE 3PAR OS version is compatible with the RMC version being used. Incompatibility between the OS versions can lead to failures in replication or other high availability features.

RMC 6.2 (Option F): RMC 6.2 is the required version for ensuring compatibility with the features necessary for Peer Copy between Primera and 3PAR arrays. Ensuring that this version is installed and correctly configured is essential for successful implementation.

These prerequisites help ensure that the high availability setup between the Primera and 3PAR arrays functions correctly and that the data protection mechanisms are reliable.

In the scenario presented, the customer requests an increase in Random Write IOPS for their HPE Primera solution. To achieve this, adding more disks of smaller capacity is the most effective approach (Option A). By increasing the number of disks, the storage system can distribute the write operations across more disks, thereby reducing the write latency and improving the overall Random Write IOPS performance. Smaller capacity disks typically allow for better IOPS performance per GB due to their higher spindle speed and lower data density, which reduces seek times.

This strategy also aligns with best practices in storage design, where increasing the number of spindles (disks) generally enhances the performance of random workloads, particularly in write-intensive environments.
