Uses for old NetApp controller modules?

[LeekSoup]

Hello,
A job I worked during the summer was throwing away a NetApp FAS2554 SAN. It was just the one 4U disk shelf with 24 drive slots. Not being one to pass up free hardware (and wanting to expand my homelab) I saved it from being recycled.

I replaced the two Processor Control Modules (PCM) with an IOM6 module to convert the device from a full-on SAN to just a “dumb” disk shelf (Like a DS4246). This has been working perfectly with my TrueNAS box since.

I now have these two controller modules hanging around gathering dust and I’m wondering if there is anything I could do with them. Obviously I could sell them or take out the CPUs and memory, but do you guys know of anything else that could be done with them? They seem to have pretty good I/O which would be nice to take advantage of in some way, but the connectors they use are (unsurprisingly) completely proprietary.
Any suggestions are welcome.

NetApp FAS2554

they use a boot DOM and most of these controllers only have a barely modified BIOS. you could pull the DOM and see if it can be plugged into a SATA port and check out the bootloader. or, with like NIMBLE controllers, it is actually fairly easy to flash the regular supermicro BIOS over the nimble BIOS and then it is just a regular PC again. even the CISCO UAC controllers can be modified back to a regular computer fairly easily, but i have not touched a NetApp appliance myself to know on those specifically.
