Product overview
Part number 4Y37A09729 identifies this Lenovo ThinkSystem RAID 940-8i 8GB flash PCIe Gen4 12Gb Adapter. Moving an array between controllers is a firmware question before it is a hardware one, and metadata written by one generation is not always read by the next. Tell us what the disks are attached to today and we will confirm the migration path.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
4Y37A09729 is what is quoted and 4Y37A09729 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Firmware and driver path confirmed
We check the controller against the host OS and the array metadata, not just the slot it fits.
Questions buyers ask about this part
Is 4Y37A09729 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 4Y37A09729 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.
