UDIMM vs RDIMM

[TechySAP]

Hello,

I am looking for some help about how much memory an HP Proliant BL460c G6 blade can support? and this appliance is being sold as SAP BWA In-Memory appliance as well to customers by HP.

One of the customers just asked me to check on RDIMMs if we can install where the blades currently are running on UDIMMs, can alone changing the memory to RDIMMs will work?

Thank you already for taking time to read and respond.
