MJ; I was looking at something similar, and reached out one of my VARs, and they recommended Netgear M4100 series switches. We don't user any of them yet, so I can't provide first-hand experience. On the subject of UTP vs SFP+; I'm told that SFP+ with DAC cables experience lower latencies than 10 Gig over copper. Thank you, Dominic L.

After a few months of use, their WEAR is still at 1%, and the cluster performance ("rados bench" etc) has dramatically improved. So all in all: yes, we're happy Samsung PM883 ceph users. :-) We currently have a "meshed" ceph setup, with the three hosts connected directly to each other over 10G ethernet, as described here: https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Method_2_.28routed.29 As we would like to be able to add more storage hosts, we need to loose the meshed network setup. My idea is to add two stacked 10G ethernet switches to the setup, so we can start using lacp bonded networking over two physical switches. Looking around, we can get refurb Cisco Small Business 550X for around 1300 euro. We also noticed that mikrotik and TP-Link have some even nicer-priced 10G switches, but those all lack bonding. :-( Therfore I'm asking here: anyone here with suggestions on what to look at, for nice-priced 10G stackable switches..? We would like to continue using ethernet, as we use that everywhere, and also performance-wise we're happy with what we currently have. Last december I wrote to mikrotik support, asking if they will support stacking / LACP any time soon, and their answer was: probably 2nd half of 2021. So, anyone here with interesting insights to share for ceph 10G ethernet storage networking?
