To be fair, there was not much Dell could do as their PERC cards were all rebranded Adaptec and later LSI. Adaptec was the gold standard for ages, but I assume was enshitified somewhere along the way. The long term result was that the entire hardware raid world ditched Adaptec for LSI and/or software RAID (eg ZFS). Dell (in those days, not sure if it's still the case) had excellent support. There was a bug on another server model where the onboard video card would eventually fail and fry the motherboard. Even years later out of support, Dell would for free replace it if it failed with whatever new model equivalent existed.

I left the company before things were totally resolved, but I think dell ultimately gave people who complained LSI cards, but it took awhile for those to be designed and manufactured to fit the internal drive slot. Most people who were also using external arrays moved to third party ones or other hardware.
