HPE0-J68 HPE Storage Solutions Free Practice Exam Questions (2025 Updated)

When expanding an HPE StoreVirtual VSA-based cluster with two additional VSA instances, it is crucial that the new instances have equal or greater capacity compared to the existing instances. This requirement ensures that the cluster maintains balanced performance and storage capacity, preventing any potential bottlenecks or imbalances that could affect the overall performance of the cluster.

HPE StoreVirtual VSA is designed to scale out by adding more instances with equal or greater capacity, allowing for seamless expansion while maintaining performance and reliability.

When adjusting the Adaptive Flash Cache (AFC) configuration in HPE 3PAR StoreServ, particularly when increasing the cache size, the correct procedure involves first removing the existing flash cache for all Virtual Volumes (VVs). After this step, you should recreate the flash cache to reflect the new increased capacity. This ensures that the system properly recognizes and utilizes the additional cache space, optimizing performance according to the new configuration.

To calculate the required capacity for snapshots after one week for an HPE Alletra 9000, we start by understanding the customer’s requirements:

Base volume size: 100TB

Snapshots: 168 snapshots per week

Daily change rate: 15%

The snapshot capacity requirement can be calculated by taking 15% of the base volume size per day, and multiplying it by the number of days (7 days in a week) and the number of snapshots per day.

Daily change: 15% of 100TB = 15TBTotal change over a week: 15TB * 7 days = 105TB

Thus, the capacity needed for snapshots after one week is 105TB.
