HPE ASE HPE0-J68 Syllabus Exam Questions Answers

When adding a new virtual volume on an HPE 3PAR StoreServ array, the minimum required information includes:

Size: The size of the volume must be specified to define how much storage will be allocated.

CPG (Common Provisioning Group): The CPG defines the storage pool from which the space for the new volume will be allocated. It is essential to specify this to ensure the volume is created with the correct provisioning settings.

Other options like Persona type, Domain, and Host are additional configurations but not mandatory for the initial creation of the volume.

After determining that a new tier of SSD drives should be installed in the HPE 3PAR StoreServ 8400, the following actions should be recommended:

Configure Adaptive Optimization (AO): AO automatically moves data between storage tiers based on real-time I/O patterns. By configuring AO, the most frequently accessed data will be moved to the new SSD tier, optimizing performance and improving efficiency.

Configure scheduled tunesys tasks: Tunesys is a command used to optimize the storage layout on the HPE 3PAR array. By scheduling regular tunesys tasks, the data is redistributed across the available drives, ensuring that the array maintains optimal performance as the storage environment evolves.

During an Intelligent (One-Click) Update on HPE Alletra dHCI, VMware vCenter is one of the components that will need to be updated manually. While the One-Click Update feature automates the updating process for various components like HPE Storage Connection Manager, Array OS, and VMware ESXi, vCenter requires a manual update because it serves as the central management hub for the VMware environment. Ensuring that vCenter is up-to-date is crucial for maintaining compatibility and stability across the entire infrastructure.

HPE StoreVirtual VSA’s Adaptive Optimization feature is ideal for addressing the challenge of intermittent heavy disk I/O in mission-critical applications. Adaptive Optimization dynamically adjusts the storage tiering based on real-time workloads, ensuring that the most frequently accessed data is moved to faster storage tiers like SSDs, without the need for manual intervention. This feature allows the customer to benefit from SSD performance when needed, without permanently dedicating SSD resources, thus optimizing both performance and cost.
