verifying failed hardware component, I think it's the integrated H730 perc raid controller

Hi, all. I have a Dell R730xd server that just went (technical terms) splat.  The error message on the console (repeatedly within a few minutes after a reboot):

OK, so on an identical server (we purchased several, with the same specs at the same time) shows

root@ourserver:~# lspci -s 0000:02:00.0
02:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3108 [Invader] (rev 02)

According to our invoice, we have

Which seems like it's potentially replaceable (unless the bus controller is a different thing). I've been looking at

https://dl.dell.com/topicspdf/poweredge-rc-h330_users-guide_en-us.pdf#unique_16

We purchased this in 2014, so of course the warranty is long gone (and that makes it tough to try and check my logic/thinking with a support ticket) but if I can source the 405-AAEG part and replace it (the data on the disks is backed up elsewhere) does that work? I'm just not entirely sure about the jump from the lspci info to the raid controller adapter ie, is the PERC the same thing as the raid bus controller or are those two different items?

Thanks for any help you can provide!
