Hello everyone!

I have a small question for you guys. I currently have a server with a P420 PCIe RAID Card on it, the card itself gets really hot (at around 80-85C, even with an added fan on the heatsink. It is a DL380 G8e server with 10x8TB in a Hardware RAID 5 array.

My question is this: I know that I can put this card into IT mode (drive passthrough to the OS) but would this mean the card temperature would get lower ? I guess yes, but I want to know your experience !

Thank you !

    It probably would lower the temp because the on-board cpu would no longer be doing the RAID controlling.

    All that work would be offloaded to the system CPU and whatever software you use to control the RAID setup (TrueNAS, Proxmox, UnRAID, etc).

    Of course this would mean backing up all the data on those drives (which you’re already doing, right) and rebuilding the array with the software you choose.

      This is exaclty what I think too. But does anyone have tested this and is the theory same as in reality?

      Backup up is not an issue of course! Restoring either, 10GB cards at the rescue!

        Every circumstance is different, but undoubtedly the RAID cpu temp will drop since it’s not doing anything.

        Also, it seems the direction today for self holsters is software RAID, which I can get behind because I’ve had RAID cards die, and when they can’t be replaced, you’re out of luck.
