       Second order hardware upgrade time! Trickle down may not work in economics but it's very real in the hardware world.All of those 16GB DDR4 DIMMs I pulled from my office desktop are going into the storage cluster to replace the 8GB sticks currently in those nodes.

       Hmm, I misremembered the hardware config. I thought all the Ceph nodes were 6x 8GB.alexandria-1 had 6x 8GB sticks (48 GB) now has 6x 16GB (96 GB).But alexandria-2 had 12x 4GB stick (48 GB) now has 6x 16GB (96 GB).Alexandria-3 currently has 12x 4GB too.I have 4x 16GB, 6x 8GB, 12x 4GB sticks out on the bench. Wut do?

       It seems like the best I can probably do with the current hardware is to put 4x 16GB in there, bumping capacity from 48 to 64 GB, but with two channels empty. That will mean a slight degradation in RAM performance from 6 to 4 channel.Then I'll put all of the 8 and 4GB sticks in the giveaway pile, and maybe see if I can eBay two more 16GB sticks at some point to get all of the cluster nodes back to a balanced configuration.
