R730 support IDSDM with part number PMR79. R720xd and R420 support IDSDM with part number 6YFN5. R230 does not support IDSDM module that is why there is no slot to connect IDSDM on the board.
Hello all, I was curious as to whether the IDSDM model PMR79 designed for x30 servers can also be used used whith x20 servers.  Thanks. Dave C
