> Out of curiosity, do you know what happens to the decomissioned hardware? is it scrapped for useful parts like perhaps the PSUs? or is gold and other metals extracted from the chips and the metal sold for recycling? I cannot state with 100% clarity what happens after the systems are acquired by surplus vendors, but I can say that we have received certificates of what was "recycled". Once the surplus vendors take possession of the hardware, it's theirs and they can do what they want with it. In fact, we recently had to purchase EOL'ed, refurbished Infiniband switches to continue to support an interconnect fabric still in use (~2016). Interestingly enough, some of the switches still had "core" and "edge" labels on them. > Is there anything useful someone could do with it or it's just too much of a problem to set it up and repurpose it? In my opinion, it really depends on the node. If the chassis supports hot swappable & redundant hardware (HDD, PSU, etc.), then we'll typically cannibalize several chassis to create an administrative and/or infrastructure node. Case in point, a large portion of our older 12 core nodes have been put aside to serve as administrative nodes, all fully redundant (RAID1 HDD's, dual PSU's, ECC memory, etc.). Since we have a stack of these, we're fairly confident that these will serve us for the next few years, worry free, given the abundance of parts lying around.
