A customer has started to load their HPE 3PAR 8450 with data, but are not sure what data reduction they are achieving. They ask you to run analysis and estimate the deduplication ratio of data currently on a virtual volume (VV).
Which CLI command should you use to understand data reduction ratios?

A customer is monitoring an existing HPE 3PAR array, which is doing synchronous replication to a remote site. The customer notices that controller utilization regularly exceeds 60% on all nodes. An HPE 3AR OS upgrade to 3.3.1 MU2 is planned in the near future to support compression on the array.
What should you inform the customer before performing the upgrade?

A customer has two data centers in a metropolitan areA. The link between the data centers is IP-based and satisfies the bandwidth and latency requirements. They have the following requirements:
* Transparently and automatically failover and fall back between sites
* Provide block and file access
* Block access must provide connectivity for fibre channel and iSCSi hosts
* All-Flash storage solution
You plan to propose a design based on HPE 3PAR storage arrays.
What would be the most cost-effective model that meets the customer needs?

A customer has a pair of HPE 3PAR arrays with Synchronous Replication enabled. They need recommendations for deploying the Quorum Witness when implementing Peer Persistence.
What should you recommend to the customer?

A customer has two HPE Nimble arrays that are replication partners. The replication schedule is set to every hour.
After replication completed at 1:00pm, the array at the primary site suffers a power failure.
Applications were failed over successfully by the administrators, and production continued on the secondary site array as designed.
At 3:00pm, the power was restored to the primary site array.
What does the administrator need to do first to restore services in the primary site?
