Replace HP Smart Array RAID Controller with newer generation controller (e.g. 410 -> 420)

hp-prolianthp-smart-array

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?

The P420 add-in card will probably work...

But it's better to go to a Gen8 server today, if possible.

ProLiant G6 severs are circa 2009. How much is reasonable to invest in a 10 year-old server?

None of the SAAP features are really crucial. And if you just want to keep your old server afloat, get another age-appropriate Smart Array P410.

By the way, since the RAID controller on the G6 systems is embedded on the system board, the failure of the controller is a really good indicator that the hardware is near the end of its life. RAID controller failures are uncommon. Embedded controller failures usually require a new system board.

Edit: You say that you already have an add-in P410 RAID controller. Why aren't you using the embedded motherboard Smart Array P410i controller?
