Huawei Storage Part Substitutions — Old to New P/N Reference

Official Huawei substitution data for storage spare parts: 1,925 part numbers carry a published replacement, covering OceanStor, Dorado and OceanDisk systems. This is the page to use when a part is discontinued or short-supplied and you need to know which P/N replaces it — and whether the replacement is genuinely equivalent.

Coverage note: this batch covers 7 of Huawei’s 21 storage product series. Pacific, OceanProtect, OceanStor 100D, FusionStorage, FusionCube and the other series are still being added, so a P/N that is missing here does not mean the part is unavailable — send it to us and we will check it against the current Huawei catalogue.

Direction and compatibility are shown as two separate columns, because they answer two different questions: can the parts be swapped, and is the replacement equivalent. A two-way, complete substitution can be quoted straight away; a one-way or conditional one needs a check first.

Reading a substitution correctly

• One-way — the replacement P/N supersedes the original; the original cannot be used in place of the replacement.
• Two-way — both parts are interchangeable.
• Complete — the replacement is functionally equivalent, same fit and same role.
• Conditional — the replacement only works under specific system, firmware or configuration conditions. Confirm before quoting.
• Not stated — Huawei’s catalogue leaves the field empty; we do not fill it in.

Two practical warnings

1. A replacement P/N is not always a sellable part. Some substitution targets are reference or sub-BOM numbers that Huawei does not offer as a standalone spare. They are shown as plain text here, without a link, so you do not chase a part number that cannot be ordered.

2. A substitution is not a stock promise. The official catalogues do not carry the spare-part attribute (RSP / NRSP / NSP). Part attributes follow Huawei’s quotation system and lead times must be confirmed separately.

Frequently asked questions

What does “one-way” mean in practice?

Huawei has superseded the old P/N with the new one. Ordering the new P/N is correct; ordering the old one will normally fail or return the replacement anyway. The reverse is not true — you cannot substitute the old part for the new one in a newer system.

What makes a substitution “conditional”?

The parts are not identical in every configuration: the substitution may depend on the system model, the firmware level, or how the slot is wired. We check those conditions before quoting.

Can a part have more than one replacement?

Yes. Nine part numbers in this dataset have two published replacement targets, and all of them are listed in the same cell. Read the direction and compatibility for the group as a whole.

Why does a replacement P/N have no link?

Because it is not itself a catalogued sellable spare part in our dataset. Linking it would send you to a 404. Ask us and we will confirm whether it can be supplied.
