NEW QUESTION 26
You are adding a Linux host running Oracle to a Dell Unity XT Hybrid array. The customer requires the Oracle application to have low I/O latency and be deployed on available 10K SAS or NL-SAS drives. Which Dell Unity XT feature would meet the customer requirements?

Quotas

FAST Cache

FAST VP

Dynamic pools

NEW QUESTION 27
Which sizer option supports configuration of a Midrange solution with hybrid dynamic pools?

Advanced Performance

Quick Configuration

System Designer

Simple Performance

When using theDell Unity XT Sizer Tool(or Dell’s Midrange Sizer), theSystem Designeroption is the one that supports advanced configurations, including hybrid dynamic pools.
#System Designer Features:
Detailed Sizing- Allows you to customize configurations at a granular level, including disk pool type, RAID configurations, and hybrid dynamic pools.
Hybrid Dynamic Pools- These pools combine SSD and HDD tiers to create a cost-effective and performance- optimized storage environment, which is a typical design for Dell Unity XT systems.
Workload Modeling- Offers more precise performance and capacity recommendations for mixed workloads.
#Why not the other options?
A). Advanced Performance- This isn’t a standalone sizer option; rather, performance considerations are built into System Designer.
B). Quick Configuration- Designed for fast sizing with minimal inputs, and it doesn’t support detailed hybrid pool configuration.
D). Simple Performance- This is not a recognized option in Dell’s Unity XT sizing tools.
#Documentation Reference:
Dell EMC Unity XT Sizer User Guide- Outlines the functionality of System Designer and confirms it’s the module to use for hybrid dynamic pool configurations.
Dell EMC Unity XT Best Practices Guide- Confirms that hybrid pools are best configured using detailed sizing, not quick configuration.

NEW QUESTION 28
A customer has invested much time using the Dell PS Series Host Integration Toolkit (HIT) to integrate SAN snapshot protection with Microsoft SQL Server native snapshot technology. The customer expresses concern about whether Dell EMC SC Series cross-platform replication supports that capability.
What should be your response?

Recreate integration on the SC Series array and use only SC-to-SC replication for those volumes.

Leverage the integration investment and use only PS-to-PS replication on those volumes.

Cross-platform replication works with SC Series HIT integrations.

Cross-platform replication works with PS Series HIT integrations.

NEW QUESTION 29
Which Dell EMC Midrange storage platforms support NVMe SCM drives?

PowerStore T and SC Series only

PowerStore T and PowerStore X

PowerStore T, Unity XT, and SC Series

PowerStore X, Unity XT, and SC Series

NEW QUESTION 30
Which statement is true about dynamic node affinity?

Maintains relatively consistent utilization, latency, and performance between both nodes.

Automatically moves NAS servers to the peer node to balance the workload.

Trespass affected block volumes between nodes.

Dynamic node affinity in Dell Unity XT systems is designed to maintain relatively consistent utilization, latency, and performance between both nodes. This mechanism ensures that workloads are balanced across the storage processors, optimizing system performance and resource utilization. By dynamically adjusting the workload distribution, it helps in maintaining stable performance and reducing latency.

NEW QUESTION 31
What is the purpose of the NVMe NVRAM drives in a Dell EMC PowerStore 9000 array?

Read cache and vaulting

Read cache and base OS

Write cache and base OS

Write cache and vaulting

Reference: https://www.delltechnologies.com/en-us/collaterals/unauth/white- papers/products/storage/h18149-dell-emc-powerstore-platform-introduction.pdf (12)

NEW QUESTION 32
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.

NEW QUESTION 33
What is a non-uniform distribution of I/O over storage capacity in Dell Unity XT Systems?

Latency

Response time

Skew

Throughput

NEW QUESTION 34
A technical architect is helping a customer prepare for a data center maintenance window. All applications must failover to the disaster recovery site. The customer also wants to test their disaster recovery plan. What PowerStore Manager replication option should be used to address the customer’s need, and from which site should the option be run?

Planned failover from target site

Planned failover from source site

Failover from source site

Failover from target site

For a customer preparing for a data center maintenance window and wanting to test their disaster recovery plan, the recommended PowerStore Manager replication option is a planned failover from the source site. This process involves initiating the failover from the source site, ensuring a controlled transition of applications and services to the disaster recovery site. Planned failover allows for testing the disaster recovery plan while maintaining data integrity.

NEW QUESTION 35
A customer must provision file systems on a Dell Unity XT 480F for a test environment A dynamic pool will be configured with RAID 5……
What is the minimum drive count necessary to create to create this pool?

NEW QUESTION 36
When designing a Metro Volume, what configuration must be implemented to avoid unnecessary storage and compute resource usage?

Use MRU for PSP.

Use DRS affinity rules.

Place witness at a third site.

Use storage containers.

When designing a Metro Volume, placing the witness at a third site is crucial to avoid unnecessary storage and compute resource usage. The witness helps in maintaining quorum and ensuring the consistency of the Metro Volume in case of a site failure. Here’s how it works:
* Witness at Third Site:Placing the witness at a separate, third site ensures that it can independently verify the status of the primary and secondary sites, maintaining high availability and failover capabilities without consuming significant resources.
* Avoids Resource Usage:By offloading the witness function to a third site, the primary and secondary sites can focus their resources on storage and compute tasks without the overhead of managing quorum.

* Dell Entry-Level and Mid-Range Storage Community

NEW QUESTION 37
Where in PowerSizer can a solution architect find guidance for choosing the appropriate storage solution?

Support

Quick Size

Recent Projects

Sizing and Build Tools

NEW QUESTION 38
How many writes per day are SAS Flash 4 drives rated at?

SAS Flash 4 drives in Dell Unity XT arrays are rated at 1 write per day. This rating indicates the drive’s endurance level and how many times the entire drive capacity can be written to per day over its warranty period. This level of endurance is designed to balance performance, cost, and reliability for general-purpose workloads.

NEW QUESTION 39
What is skew?

Uniform distribution of I/O over storage capacity

Sustained per-port IOPS

Bursty per-port IOPS

Non-uniform distribution of I/O over storage capacity

Skew refers to the non-uniform distribution of I/O over storage capacity. In storage systems, skew is an important factor to consider as it indicates that certain areas of the storage receive more I/O operations than others. This can lead to performance hotspots and affect the overall efficiency of the storage system.
Managing skew is essential to ensure balanced performance across the storage array. Reference:Dell Midrange Storage Performance Guide
