What chunk size of data is identified and moved temporarily to FAST Cache within Unity?
C
Explanation:
FAST Cache Mechanism:
FAST (Fully Automated Storage Tiering) Cache in Dell Unity systems temporarily holds frequently
accessed data to improve read and write performance.
The data moved to FAST Cache is managed in chunks to optimize storage efficiency and performance.
Chunk Size for FAST Cache:
Dell Unity systems use a chunk size of 128 KB for data moved to FAST Cache. This size is optimized for
balancing performance and storage management overhead.
Smaller chunks, such as 32 KB or 64 KB, might increase management overhead, while larger chunks
like 256 KB could reduce the granularity of data movement and efficiency.
Dell Midrange Storage Reference:
Dell Unity XT documentation provides detailed explanations on FAST Cache operations, including the
specific chunk sizes used.
Additional technical resources from Dell Technologies offer insights into performance tuning and
cache management.

What can be done to provide best performance on Dell Unity iSCSI connections?
A
Explanation:
To provide the best performance on Dell Unity iSCSI connections, configuring Jumbo frames end-to-
end is recommended. Jumbo frames allow for larger packet sizes than the standard 1500 bytes,
typically up to 9000 bytes. This reduces the number of packets transmitted, decreases CPU
utilization, and improves overall network efficiency. Here’s how to configure Jumbo frames:
Switch Configuration: Enable Jumbo frames on all network switches that will handle iSCSI traffic.
Network Interface Configuration: Configure all network interfaces (NICs) on the storage system and
the iSCSI hosts to support Jumbo frames.
End-to-End Consistency: Ensure that Jumbo frames are configured consistently across the entire
network path from the storage system to the hosts to avoid fragmentation and performance
degradation.

Which two parameters avoid bottlenecks and improve performance when sizing Dell Unity XT
storage solutions? (Select 2)
B
Explanation:
When sizing Dell Unity XT storage solutions, avoiding bottlenecks and improving performance can be
achieved by considering the following parameters:
Port Utilization: Ensuring that the storage system’s ports are utilized efficiently helps in distributing
the workload evenly across available resources, preventing any single port from becoming a
bottleneck.
Workload Types: Understanding and categorizing different workload types (e.g., random vs.
sequential, read vs. write) allows for better allocation of resources and tuning of the storage system
to handle specific performance requirements.

What benefit do higher capacity drives provide in a Dell Unity All Flash array?
B
Explanation:
Higher capacity drives in a Dell Unity All Flash array provide the benefit of using less physical space.
This is particularly advantageous in data centers where space is at a premium. By utilizing higher
capacity drives, more storage capacity can be achieved within the same physical footprint, leading to
greater efficiency and potential cost savings. Here’s why higher capacity drives are beneficial:
Space Efficiency: Higher capacity drives allow for more data to be stored in fewer drives, conserving
rack space.
Cost Savings: Fewer drives can reduce power and cooling requirements, leading to operational cost
savings.
Scalability: Higher capacity drives enable easier scalability as storage needs grow, without requiring
additional physical space.
