I know this is in Chassis and Enclosures but it relates to those.
I currently have 5 sandy bridge/haswell era Proxmox nodes, each with about 30TB worth of drives (of sizes 8, 4, 3, 2, and 1TB) spun up and all pooled together with Ceph. This works well for the most part, but I'm not sure its the most optimal.
I currently use CephFS to get data on/off and treat it as my NAS and storage for my docker containers.
I'm considering re-architecting to two storage nodes, each with ~75TB (half the total pool) in some BTRFS/LVM span, and then mirroring between the two nodes with GlusterFS. Then selling all the other components and buying a beefy compute server (probably Epyc).
I have on-prem working tape backup (tested). This is connected to a dedicated server with fiber channel
I also have offsite-cloud backup (also tested).
Question 1: Is this a wise(r) idea than what I currently have?
All these nodes are in 2u Supermicro Chassis (SC825 and S826's).
Question 2: Am I better off keeping these 2U systems, or should I investigate disk shelves? The systems are currently stock with no modifications.
I'm less familiar with the noise/power of disk shelves than the servers (65W draw each, without disks)
The ultimate goal would be to reduce power while maintaining HA storage resources and minimal HA core infrastructure (could run on a raspi easily, so low hw requirements)
