Identity & purchasing scope
This record identifies P00918-H21 in the HPE memory catalog. Its classification is oem option part number. Preserve the full identifier when comparing offers: suffixes, revisions and assembly contents are part of the purchasing question.
ASTER RACKIT research entry for HPE P00918-H21. An OEM product index lists this identifier. Technical specifications and compatibility remain under review. Submit the exact identifier and intended platform in your RFQ so the required configuration can be checked. Use the technical record to prepare an inquiry rather than as evidence that an item is available, tested, licensed or covered by a particular warranty. Inherited fast-shipping and stock language is not carried into this catalog's commercial fields.
Inherited search aliases: P00918-H21 · P00918 H21. These are lookup aids, not certified equivalents.
Recorded technical specifications
Each field states its evidence status. Inherited and title-derived values remain unverified; reviewed OEM facts do not certify an offered configuration.

Configuration & purchase checks
- Confirm the complete module number, capacity, DDR generation, buffer type and organization instead of matching capacity alone.
- Use the platform population rules. The speed printed on a DIMM is not a promise of operating speed in every processor and slot combination.
- List the modules already installed and the modules being added. Existing parts are part of the compatibility question, not an afterthought.
- Confirm processor count, accessible slots and a growth target. A logical slot-count picture is not the OEM physical installation sequence.
- Ask for module labels and a memory-test record that identifies the tested system and population.
Adding an item prepares a local RFQ line. It does not create a price offer, reserve inventory or submit an order.

No explicit target-platform relationship is provided for this record. Brand, socket, capacity and visual resemblance alone must not be used to invent a compatibility claim.

Test scope
No server boot-screen image is attached to this record. Request product photographs and any diagnostic or entitlement record as separate evidence.
At acceptance, compare the delivered unit, labels and accessories with the approved list. Retain source revisions and receiving records for later maintenance.
Source trace & documentation
Remaining review: exact manufacturer model spelling · product family · category · chassis · height · drive bays · ports · CPU · GPU · memory · storage · power · network · management · lifecycle · compatibility · current availability · compatibility: Verify target platform, carrier/slot, firmware and source notes for the actual requested option. · physicalUnit: Condition, serial/label image, included accessories and actual-unit inspection are not established by an OEM ordering table. · physicalIdentity: Documented OEM product-line ordering suffix may refer to the same physical module. Preserve full PN but do not count as a distinct physical identity without separate evidence.

Frequently asked questions
Is the item currently available?
This is not a live stock feed. Confirm full identifier, condition, quantity, price and delivery scope in a written quotation.
Does this record certify compatibility?
No. Inherited fields and platform associations require review against the exact destination system and current manufacturer documentation.
What should I send in an RFQ?
Include the full identifier, quantity, destination, target platform, condition, accessories and evidence needed for acceptance.
Is a configuration number another server model?
No. Models, ordering configurations, options and reference labels are distinct record types. Ask which actual purchasing unit will be supplied.
