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?

  • You should have specified your server model in the initial post. – ewwhite Sep 22 at 16:08

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?

  • Just a brief correction - the P410 is a standalone PCIe-expansion card. SA Controllers embedded onto the system board are usually designated by an "i" (integrated) like a P410i. Nevertheless thank you :) – Yannik Z. Sep 20 at 13:02
  • Why aren’t you using the embedded RAID controller? It should be present on that system. – ewwhite Sep 20 at 17:13

    If a ten-year-old server is still running and meeting the OP's needs, is there a reason to replace it? Computer performance over the past 10 years has not seen the spectacular growth of any prior decade. – Mark Sep 20 at 21:58
  • To reiterate Mark's point, the best home desktop I've ever had I bought in 2011 and while there is a price discrepancy with newer comparisons I'm making, it performs on par with anything I've had since (for all practical applications I need - not gaming or heavy graphical work). Biggest changes are almost exclusively in efficiency. P.S. I'm excluding 20+ core processors as an advancement because very little software can make use of them effectively. – TCooper Sep 20 at 22:14

    Oh, DL180's are vastly different than the DL300-series in the G6 variant. For this hardware, you can use any controller you wish provided the backplane connectors are compatible (SAS SFF-8087). This model really isn't a traditional ProLiant, and has proven to be far more reliable than the DL300-series of the same generation. Disregard what I said about system board. – ewwhite Sep 22 at 16:07
