NEW QUESTION 33
A systems administrator has deployed a Dell Unity XT 380F system with 15x 1.92 TB SSD drives, in a RAID 5 dynamic pool. Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density. What will happen if the administrator adds 4x 3.84 TB SSD drives?

The full capacity of the drives will be available.

Only half of the capacity of the new drives will be available.

Three of the drives will be added with a fourth reserved as spare.

The mixing of drive types is not supported, and the operation will fail.

When the administrator adds 4x 3.84 TB SSD drives to a RAID 5 dynamic pool in a Dell Unity XT
380F system, the full capacity of the new drives will be available. Dell Unity XT systems support mixing different drive sizes within a dynamic pool, allowing administrators to expand the storage capacity seamlessly.

NEW QUESTION 40
For a PowerStore 3200T running Block Workloads, which two options does Sizer take into consideration to equate the performance for each workload? (Select 2)

Throughput

Frontend Performance Saturation

Response Time

Storage Performance Saturation

For a PowerStore 3200T running block workloads, the Sizer tool takes into consideration several factors to equate the performance for each workload. The two main options are:
Throughput: This refers to the amount of data that can be processed by the system in a given period. It is a critical measure of the storage system’s capability to handle large volumes of data efficiently.
Response Time: This metric measures the time taken to complete an I/O operation from the moment it is initiated. It is essential for assessing the performance of latency-sensitive applications.
These parameters help ensure that the storage solution is designed to meet the performance requirements of the workload, balancing between high throughput and low response times.

NEW QUESTION 43
Which two statements are correct for a PowerStore 5200T with mixed SSD and SCM drive combination? (Select 2)

Expansion Enclosures are supported.

NVMe drives are not used for Caching and Vaulting.

SSD drives are used for metadata tiering.

SCM drives do not add to usable capacity.

For a PowerStore 5200T system with a mixed SSD and SCM (Storage Class Memory) drive combination, the following statements are correct:
Expansion Enclosures are supported: PowerStore 5200T supports expansion enclosures, allowing for the addition of more drives to increase storage capacity and performance. This flexibility is crucial for scaling the storage system to meet growing data requirements.
SCM drives do not add to usable capacity: SCM drives in the PowerStore 5200T are primarily used for caching purposes rather than for adding to the system’s usable capacity. These drives improve performance by accelerating data access times but do not contribute directly to the overall storage capacity.
