I'm trying to re-purpose an old Tape Drive, and not having much luck. As side-question to this process, the drive has two smaller connectors to the left of the normal SAS connectors, and I don't know what they are.
Picture is below, with obligatory free-hand circle:
It's hard to see here, but the connector on top has 14 pins and the one on bottom has 4.
What are these connectors, and what are they used for?
