In a Dell Unity XT system, SSD wear alerts are issued at 180-, 90-, 60-, and 30-day periods before the predicted end of life.
What is automatically initiated on the spare drive at 30 days?

  1. Predictive Copy Operations
  2. Protective Copy Operations
  3. Preemptive Copy Operations
  4. Proactive Copy Operations

Answer(s): D

Explanation:

SSD Wear Alerts in Unity XT:

Dell Unity XT systems monitor SSD wear and issue alerts at various intervals (180, 90, 60, and 30 days) before the predicted end of life.

Action at 30 Days:

At the 30-day alert, the system automatically initiates Proactive Copy Operations to copy data from the wearing SSD to a spare drive, ensuring data integrity and continuity.

Proactive Copy Operations:

This proactive measure helps prevent data loss and maintains system performance by preparing for SSD replacement in advance.

Which two workload parameters are required to proceed with sizing for a PowerStore solution? (Select 2)

  1. Response time
  2. IOPS
  3. Effective Capacity
  4. Data reduction ratio

Answer(s): B,C

Explanation:

Sizing for PowerStore Solutions:

Accurate sizing for PowerStore solutions requires specific workload parameters to ensure that the storage system meets performance and capacity requirements.

Required Parameters:

IOPS (Input/Output Operations Per Second): A key performance metric indicating the number of read/write operations the system must handle. Essential for determining the required performance capability.

Effective Capacity: The usable storage capacity after considering data reduction technologies like compression and deduplication. Critical for ensuring the system can accommodate the data volume.

Other Parameters:

Response Time: While important for performance, it is not typically required to proceed with sizing.

Data Reduction Ratio: Influences effective capacity but is not a direct input for initial sizing.

What is the minimum number of drives in a RAID 6 dynamic pool?

  1. 8
  2. 9
  3. 6
  4. 7

Answer(s): A,B

Explanation:

RAID 6 Dynamic Pool Configuration:

RAID 6 provides high data protection by using double parity, allowing for two drive failures without data loss.

Minimum Number of Drives:

A RAID 6 dynamic pool in Dell Unity XT systems requires a minimum of 8 drives to configure. This includes 2 drives for parity and 6 drives for data storage.

Drive Configuration:

The minimum configuration ensures that the system can provide the necessary data protection and redundancy while maintaining performance.

What is Dell's recommendation for scheduling FAST VP relocation?

  1. Before backups or nightly batch processing
  2. During backups or nightly batch processing
  3. After backups or nightly batch processing
  4. Before and After backups or nightly batch processing

Answer(s): A

Explanation:

Dell recommends scheduling FAST VP (Fully Automated Storage Tiering for Virtual Pools) relocations before backups or nightly batch processing to ensure optimal performance. This scheduling helps to avoid conflicts and performance degradation that can occur if relocation tasks compete for resources during critical data operations such as backups. Pre-scheduling these relocations ensures that the storage system is balanced and ready for intensive operations without impacting performance.
