Product overview
Lenovo lists 4Y37A78836 as a ThinkSystem RAID 940-8e 4GB flash PCIe Gen4 12Gb external Adapter. Controller choice ties to firmware and driver support on the host, and a card that fits the slot may still be unsupported by the platform. We confirm the firmware and driver path alongside the hardware.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

What you get ordering this from us
Ordered by part number
The order is placed against 4Y37A78836, not against a description of it, so there is no room for a substitution you did not agree to.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Cache backup quoted with it
The battery or flash backup module is priced alongside the card rather than discovered missing at install.
Questions buyers ask about this part
- Is 4Y37A78836 genuine and is the warranty intact?
- Yes — new and sealed, with the Lenovo warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will 4Y37A78836 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.
