Compatibility
The Cisco documents cited in the sources list HX-ML-128G4RW as an option for Cisco HyperFlex HX240c M6. That listing is the only compatibility claim recorded here: the part is not assumed to fit other generations or other product lines of the same brand. Firmware, software, slot, backplane and controller requirements are set out in the vendor documentation for the specific product, and the vendor's compatibility tool should be checked before ordering a second-hand unit.
Buying used
Check that module type, speed, rank and capacity match the product ID, and that the label carries the Cisco part number rather than only the original maker's label. Run a memory test or check the server inventory after fitting it, since second-hand modules are not always tested.
