HP HPE0-J68 Practice Test - Questions Answers, Page 18

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 = 15TB Total change over a week: 15TB * 7 days = 105TB

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

For HPE GreenLake for Block Storage systems, particularly when equipped with two enclosures or cages, and considering a high availability (HA) level for drives, the maximum set size value that can be manually set is 6+2. This configuration means there are six data drives and two parity drives, ensuring that the system can withstand the failure of two drives while still protecting the data.

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.

V The NAND memory controller is the component responsible for wear leveling in SSDs. Wear leveling is a process used to extend the lifespan of NAND flash memory by ensuring that write and erase cycles are distributed evenly across the memory cells. This prevents any single cell from being overused, which could lead to premature failure. The NAND memory controller plays a crucial role in managing this process, ensuring the reliability and longevity of the SSD.

This feature cannot be retroactively applied to existing backup devices; it must be configured at the time of setup to ensure that all data written to the storage device is encrypted. This hardware-assisted encryption feature is critical for enhancing the security of stored data, protecting it from unauthorized access in the event of physical theft or unauthorized access.
