"I ended up between the Supermicro SSG-6048R-E1CR60L or the SSG-6048R-E1CR90L – the E1CR60L is a 60-bay 4U chassis while the E1CR90L is a 90-bay 4U chassis. This nice part is that no matter which platform you choose Supermicro sells this only as a pre-configured machine – this means that their engineers are going to make sure that the hardware you choose to put in this is all from a known compatibility list. Basically, you cannot buy this chassis empty and jam your own parts in"

This is a major departure from the Supermicro business model and practices and basically broke all of our next generation expansion roadmaps.

This was not a technical decision - it is the same old economic decision that every large VAR/integrator/supplier has succumbed to for the last 30 years. They aren't the first ones to try this trick and they won't be the last.

We (rsync.net) are not playing ball, however. After 16 years of deploying solely on supermicro hardware (server chassis and JBODs) we bought our first non-supermicro JBOD last month.
