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.

The REST API (Option A) is a critical feature that allows HPE Primera, HPE Nimble, and HPE XP arrays to work with third-party management tools. REST APIs provide a standardized interface for programmatically accessing and controlling the storage arrays. This enables integration with various management platforms, automation scripts, and orchestration tools, allowing for greater flexibility and streamlined management in diverse IT environments.

By using REST API, organizations can integrate their HPE storage systems with existing management frameworks, ensuring a cohesive and efficient infrastructure management approach.

HPE Storage Management

When managing HPE Primera arrays, it's important to assess the current compaction ratios to understand how effectively data is being stored.

NinjaStars is an HPE tool specifically designed to analyze and report on data reduction technologies, including deduplication and compression, on HPE storage arrays like Primera. It helps in determining the compaction ratios, providing insights into how efficiently the storage capacity is being utilized.

The exhibit refers to a configuration scenario where properties of a volume set, specifically VMwareDatastores-GF, are being verified. The question focuses on identifying the RAID level used on this volume.

RAID 5 is a common configuration in many storage arrays because it provides a balance of performance, capacity, and data protection. In RAID 5, data is striped across multiple disks with parity information distributed among the disks. This parity allows for the recovery of data in the event of a single disk failure, making it a preferred choice for environments that require efficient storage utilization with a degree of fault tolerance.

HPE storage solutions, such as HPE Nimble Storage and HPE 3PAR, often employ RAID 5 for use cases involving virtualized environments like VMware datastores. These solutions are optimized for high performance and data protection, ensuring that even with a single drive failure, the data remains accessible and the system can continue to operate without significant performance degradation.

In a Fibre Channel (FC) SAN, the World Wide Name (WWN) serves as a unique identifier for devices within the network. The WWN is used in several critical functions:

Identification of zone members (Option A): WWNs are used to define and manage zones within a SAN. Zoning is a method of grouping devices, such as servers and storage arrays, to control access and ensure data security. By identifying zone members via their WWNs, administrators can control which devices can communicate within the SAN.

Identification of entities via Storage Name Server (SNS) (Option C): The WWN is registered with the Storage Name Server (SNS) in the SAN fabric. The SNS maintains a database of all devices within the SAN and their associated WWNs, enabling efficient routing of data frames to the correct destination.

These features make the WWN a fundamental element in the operation and management of a Fibre Channel SAN.
