So some context for this, we had 2x of these sitting in the data centre for a long time before it got decommissioned and sent back to the office because theres some data I need to retrieve from there.

I haven't got any diagrams to know how this was initially connected but I've managed to plug in a bunch of ethernet cables and SFB cables into the switches that these were originally plugged into using the Dell Powervault Disk manager I can somewhat see that two are connected but I can't actually get any data from them.

Not even sure what Raid these are on, or the actual storage size.

To me it feels like a guessing game but is there an actual way to grab data from this or resetting it to make it accessible?

Any documentation would be helpful.
