I have got a faulty P410 Smart Array Controller in my G6 ProLiant, so I decided to replace it. Since I want more flexibility, I choose not to replace it with just another P410, but the succeeding P420 (much of the SAAP-functionality comes with it at no further licensing cost).
Apart from the P420 being a PCIe 3.0 card, whereas the P410 and my server only provide PCIe 2.0, are there any other incompatiblities that might arise?
I've read a statement by HP that it should be technically possible, but can anybody confirm this from his/her own business experience?
