  • In February 2015, tesla began replicating the MariaDB databases from watt.
  • In March 2015, 16GB of memory was added to bring the total to 24GB.
  • In May 2015, tesla suffered it's first drive failure. Recovery was a success.
  • In May 2015, ZFS was upgraded from 0.6.3 to 0.6.4.
  • In February 2016, the IB HCA was upgraded to a dual-port card to support a new link to watt.
