Replacing HP P410 with P420 and keeping the data

hardware-raidhphp-prolianthp-smart-arrayraid

Would it be possible to replace HP P410 raid card with a HP P420 raid card while keeping the data?

I've replaced P410 with P410 without any issues obviously. I believe they use the same software, so I'm guessing this would be possible.

If I were to try it, can I go back to P410 if P420 replacement doesn't work?

Best Answer

From the P420 QuickSpecs:

Data Compatibility among most current shipping Smart Array controllers allows simple and easy upgrades any time needs for higher performance, capacity, and availability increase. Even successive generations of Smart Array controllers understand the data format of other Smart Array Controllers.

So it would appear that it should just work.

As always, do make sure you have good backups and if you are unsure of the compatibility do contact the vendor.
