What you get ordering this from us
Ordered by part number
The order is placed against P58335-B21, not against a description of it, so there is no room for a substitution you did not agree to.
Firmware and driver path confirmed
We check the controller against the host OS and the array metadata, not just the slot it fits.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is P58335-B21 genuine and is the warranty intact?
Yes. It ships new in HPE packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will P58335-B21 work in my server?
Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it: firmware revision and platform generation matter, and this is the check that prevents a return.
Do you accept purchase orders and quote at volume?
Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.
