Huawei OceanStor and Dorado model index (86 models)

86 models, and the count per model ranges from 3 to 526

This page is the index from the other direction. Instead of starting from a part number, you start from a system and ask what is documented for it. Across 86 models the catalogue lists 15,123 part-number links, but they are distributed very unevenly: the smallest entry has 3 part numbers and the largest has 526, a spread of more than two orders of magnitude.

The spread is not a data problem. It follows from how Huawei documents spares: a model that sold in volume and ran for many years accumulated a long parts list, while a model that is a product-family name rather than a chassis has almost nothing attached to it.

The models with the longest parts lists

The top of the list is the mid-range workhorses. These are the systems that were deployed in the largest numbers and stayed in service longest, so they accumulated the most spares across the most component categories.

If you are searching for a part and you do not know the model, starting from the largest models is usually faster than starting from the smallest, because a widely deployed model is more likely to contain the part you are holding.

The models with almost nothing attached

At the other end, a handful of entries carry fewer than twenty part numbers. These are not under-documented systems: they are either product-family names used as a grouping label, or appliances whose internals are not released as field-replaceable units at all.

Practical reading: if a model shows three part numbers, do not conclude the system has three parts. It means Huawei did not publish a field-replaceable list for it. We confirm those cases per enquiry.

Which component categories appear across the most models

The column that matters for cross-referencing is not how many parts a model has, but which categories appear in how many models. A category present in most models can be cross-referenced broadly; a category present in a few cannot.

Drives, controllers, power and fans appear almost everywhere, which is why those pages on this site are the longest. Categories like quorum servers or PDUs appear in a handful of models and are the ones most often ordered by mistake.

Why a 526-part model and a 3-part model are both correct

A spare-parts list is a published artefact, not a bill of materials. It records what a vendor chose to release as a field-replaceable unit for a given system, at a given time. Two systems with similar hardware can have very different published lists, because one vendor line released individual modules and another released assemblies.

• A large count means granular field replacement was supported: individual fans, boards and cages.
• A small count means the vendor released assemblies only, so the repair unit is larger.
• A model name that is a family label rather than a chassis will always show a small count.
• A missing part does not mean the part does not exist — it means it is not in the published list.

How to use this page

• Start with the model as it is written on the system label, not the marketing name.
• Check the part-number count first: a very low count means the list is an assembly list, not a module list.
• Use the category spread to see whether the part you need is likely to be published for that model.
• If your model is not here, the part may still exist — send us the model and the description.

Frequently asked questions

My model shows only a few part numbers. Does that mean parts are unavailable?

No. It means Huawei did not publish a granular field-replaceable list for that system. Parts can still exist; we confirm per enquiry.

Why does one model have 526 part numbers?

Because it was widely deployed and Huawei released granular field-replaceable units for it across many categories.

Can I order a part for a model that is not on this page?

Yes, if it exists. Send the model and the part description; the index is a guide, not a closed list.

Does the category spread tell me whether a part will fit?

It tells you whether that category is published for the model. Fit still depends on the specific part number.

Are these all the models Huawei ever sold?

No. This is the set covered by the catalogue we publish. Older or region-specific models may be absent.
