D-PST-DY-01 vs D-PST-DY-23: What Changed in the Dell PowerStore Deployment Exam?

The most important change is that D-PST-DY-01 is more deployment-oriented. Instead of concentrating primarily on individual PowerStore storage functions, the new exam covers the broader lifecycle of deploying, integrating, configuring, validating, and maintaining a PowerStore environment.

PowerStore fundamentals now carry more weight

In D-PST-DY-23, PowerStore Concepts and Features accounted for only 5% of the exam. Candidates were expected to understand PowerStore systems, configurations, models, architecture, and hardware components.

D-PST-DY-01 increases the emphasis on these fundamentals to 12% under PowerStore Fundamentals. The new objectives include understanding PowerStore architecture and hardware components and validating architecture and hardware requirements for deployment.

This means candidates should not treat architecture as a minor introductory topic. Preparation should include:

●PowerStore architecture

●Appliance and cluster concepts

●Hardware components

●Deployment requirements

●PowerStore configurations and models

●Infrastructure prerequisites

A solid understanding of the platform's architecture provides the foundation for the practical deployment objectives that follow.

Implementation becomes the largest exam domain

One of the biggest differences is the expansion of PowerStore Implementation.

D-PST-DY-23 allocated 10% to implementation. Its objectives included Ethernet switching, initial system configuration, and licensing.

For D-PST-DY-01, PowerStore Implementation represents 30%, making it the largest individual domain.

The new objectives specifically emphasize practical deployment activities such as:

●Configuring Ethernet switches

●Installing and cabling PowerStore appliances

●Installing PowerStore using the Initial Configuration Wizard (ICW)

●Adding appliances to an existing cluster

●Using PowerStore Manager

●Using the PowerStore CLI

●Working with deployment scripts

This represents a significant shift in exam emphasis. Candidates should be prepared to understand how a PowerStore system is actually deployed, rather than focusing exclusively on what individual PowerStore features do.

Troubleshooting and validation become a separate focus

D-PST-DY-23 did not have a separate troubleshooting and validation domain.

D-PST-DY-01 introduces Troubleshooting and Validation at 16%.

This is particularly important because the objectives are closely connected to real-world deployment activities. Candidates need to understand how to validate an installation, identify configuration issues, and use available PowerStore management tools.

The exam specifically references:

●Ethernet switch configuration

●Appliance installation and cabling

●ICW-based installation

●Adding appliances to clusters

●PowerStore Manager

●PowerStore CLI

●Deployment scripts

Therefore, candidates should study not only the correct deployment procedure but also what can go wrong during deployment and how PowerStore tools can be used to investigate issues.

Storage provisioning moves into post-installation configuration

D-PST-DY-23 dedicated separate domains to storage provisioning:

●Block Provisioning 15%

●File Provisioning 15%

●VMware Provisioning 15%

D-PST-DY-01 reorganizes these capabilities into a broader Post-Installation Configuration domain worth 26%, while VMware integration is separately represented under External Integration.

The new exam expects candidates to understand tasks such as:

●Provisioning block storage

●Configuring host access

●Provisioning file storage

●Configuring NAS clients and permissions

●Deploying PowerStore NAS servers

●Creating and managing related file systems

●Configuring data protection policies

The underlying storage concepts from D-PST-DY-23 therefore remain valuable. However, candidates should study them from a deployment and post-installation perspective.

VMware moves into external integration

VMware was a significant component of D-PST-DY-23. The exam covered VMware storage provisioning, ESXi host access, and protection policies for virtual machines created on vVols.

D-PST-DY-01 places VMware-related objectives under External Integration, worth 8%.

The listed objectives include:

●Integrating PowerStore with VMware

●Adding vCenter to PowerStore

This suggests that candidates should understand the relationship between PowerStore and the VMware environment, particularly the integration and configuration process.

Candidates transitioning from D-PST-DY-23 should therefore retain their VMware and vVol knowledge while adding greater emphasis on vCenter integration and PowerStore deployment workflows.

Migration and import receive a smaller weighting

Migration was a major area in D-PST-DY-23, accounting for 15%.

D-PST-DY-01 includes Migration and Import at 8%.

The new objectives focus on:

●Importing customer data into a new system

●Configuring internal migration

Although the weighting is lower, migration remains an important PowerStore capability. Candidates should understand the migration process, supported sources, requirements, and configuration considerations.

Remote protection is no longer a standalone domain

D-PST-DY-23 allocated 15% to PowerStore Remote Protection and explicitly covered remote replication for:

●Block storage

●File storage

●VMware storage

D-PST-DY-01 does not list Remote Protection as an independent domain. Instead, data protection policies appear within Post-Installation Configuration.

This does not mean data protection is irrelevant. Rather, the new exam appears to organize protection-related knowledge around the broader configuration and deployment lifecycle.

Candidates should continue reviewing:

●Protection policies

●Storage resource protection

●Replication concepts

●Protection configuration

●Different PowerStore storage types

How D-PST-DY-23 candidates should adjust their preparation

Candidates who previously studied D-PST-DY-23 already have a useful foundation. Many core PowerStore concepts remain relevant, including architecture, block and file provisioning, VMware integration, data protection, and migration.

However, simply following an old D-PST-DY-23 study plan may leave important gaps.

Recommended study order for D-PST-DY-01

A better approach is to prioritize the new D-PST-DY-01 domains in roughly this order:

PowerStore Implementation 30%

Spend substantial time understanding the complete deployment workflow, including switching, cabling, ICW, cluster expansion, PowerStore Manager, CLI, and deployment scripts.

Post-Installation Configuration 26%

Review block and file provisioning, host and NAS client access, permissions, NAS servers, file systems, and data protection policies.

Troubleshooting and Validation 16%

Learn how to validate deployments and identify common configuration or installation problems.

PowerStore Fundamentals 12%

Strengthen your understanding of architecture, hardware, configurations, and deployment requirements.

Migration and Import 8%

Review migration concepts and the procedures for importing customer data and performing internal migration.

External Integration 8%

Focus on VMware integration, particularly vCenter configuration and PowerStore integration.

What candidates should take away from the exam change

The transition from D-PST-DY-23 to D-PST-DY-01 represents more than a simple exam-number change. The new exam reorganizes the objectives around the end-to-end PowerStore deployment lifecycle.

D-PST-DY-23 placed relatively balanced emphasis on storage provisioning, VMware provisioning, remote protection, and migration. By comparison, D-PST-DY-01 gives much greater weight to implementation, troubleshooting, validation, and post-installation configuration.

For candidates preparing for D-PST-DY-01, the key takeaway is to move beyond memorizing PowerStore features. Preparation should focus on understanding how to deploy a PowerStore environment, configure it correctly, integrate it with infrastructure such as VMware, provision storage, apply protection, validate the environment, and handle common deployment issues.

Candidates coming from the retired D-PST-DY-23 exam should use their existing knowledge as a foundation, but update their preparation around the new domain structure and especially the 30% Implementation and 16% Troubleshooting and Validation sections.
