This task will track the installation of memory upgrades in ganeti100[5-8] systems. The memory upgrades were originally requested on T242885, and ordered on T243442.
Each ganeti node will likely need to be drained and rebalanced to accomodate the downtime (and full power down/power removal) for each of these hosts to have their memory go from 4*16GB dimms (64GB total) to 8*16GB dimms (128GB total).
@jclark-ctr or @cmjohnson will need to work with @akosiaris to drain/rebalance each node.
