Huawei storage technologies are widely used in enterprise data centers, cloud infrastructure, backup environments, distributed storage platforms, and disaster recovery solutions. For presales engineers and solution consultants, understanding Huawei storage products is not only about knowing product names, but also about being able to recommend the right solution based on customer needs.

The HCSP-Presales-Storage certification is designed for professionals who work in Huawei storage presales roles. It validates a candidate’s ability to understand Huawei storage products and solutions, guide customers, recommend suitable architectures, and support the sales process with technical knowledge.

Currently, many candidates may notice two related exam codes:

Although both exams are related to the HCSP-Presales-Storage certification direction, they are not exactly the same. The most important point is that H25-621 is the new HCSP-Presales-Storage V1.0 exam, while H19-338_V3.0 is the older version that many candidates may already be familiar with.

The H25-621 exam is officially named HCSP-Presales-Storage V1.0. It is intended for presales engineers who are capable of guiding, recommending, and selling Huawei storage products and solutions.

This exam focuses on Huawei’s main storage product families and related solution capabilities. Candidates are expected to understand not only basic product positioning, but also deeper technical details that allow them to communicate effectively with customers in presales scenarios.

The exam proves that candidates have systematically understood and mastered Huawei storage products and solutions, including:

● OceanStor Dorado storage solutions

● OceanStor Pacific distributed storage solutions

● OceanProtect backup solutions

● DCS full-stack datacenter solution

● Data Management Engine-DME solutions

● OceanStor reliability technologies

● Storage POC test design

In short, H25-621 is not just a product knowledge exam. It is a presales solution-oriented exam that tests whether candidates can understand Huawei storage technologies and discuss them with customers from a technical and business perspective.

The H19-338_V3.0 exam is the previous HCSP-Presales-Storage V3.0 exam. Many candidates may already know this exam code because it has been used for Huawei storage presales certification preparation for some time.

H19-338_V3.0 also focuses on Huawei storage products and presales solution knowledge. It covers similar areas such as OceanStor products, storage reliability, data protection, backup, distributed storage, and solution design.

However, compared with H25-621, the H19-338_V3.0 exam belongs to the older version naming system. Since Huawei has introduced H25-621 HCSP-Presales-Storage V1.0 (New), candidates should carefully confirm which exam code is currently required before registering.

The most important difference is not only the exam code, but also the version status. H25-621 is officially identified as the new HCSP-Presales-Storage V1.0 exam, so it should be treated as the more current option.

If you are not sure, always check the exam code in the official Huawei certification or exam registration system before scheduling your exam.

Before registering, candidates should check three things:

Do not rely only on old blog posts or outdated candidate discussions. Check the latest exam listing in the Huawei certification or exam delivery platform.

H25-621 and H19-338_V3.0 may cover similar storage presales concepts, but they should not be treated as identical exams.

HCSP-Presales-Storage is a presales-oriented certification. Candidates should understand how Huawei storage products solve real customer problems, not only memorize product names.

The H25-621 HCSP-Presales-Storage V1.0 exam and the H19-338_V3.0 HCSP-Presales-Storage V3.0 exam are both related to Huawei storage presales certification, but they represent different exam versions. The key point for candidates is clear: H25-621 is the new HCSP-Presales-Storage V1.0 exam, while H19-338_V3.0 is the older version. If you are starting your preparation now and want to follow the latest certification requirement, H25-621 is generally the better exam to choose.

H25-621 focuses heavily on Huawei OceanStor Dorado, OceanStor Pacific, reliability technologies, OceanProtect backup storage, DCS, DME, and POC test design. Candidates who want to pass this exam should focus on Huawei’s current storage solution portfolio and understand how to recommend the right storage solution for different customer needs.

In short, for most new candidates, H25-621 HCSP-Presales-Storage V1.0 should be the preferred exam for earning the HCSP-Presales-Storage certification, unless your organization or exam platform still specifically requires H19-338_V3.0.
