Product overview
The Lenovo ThinkSystem RAID 540-8i PCIe Gen4 12Gb Adapter is supplied under part number 4Y37A78834. 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
4Y37A78834 is what is quoted and 4Y37A78834 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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 4Y37A78834 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will 4Y37A78834 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.
