3 SUSE Enterprise Storage monitor nodes recommended.
2 GB of RAM per monitor.
SSD or fast hard disk in a RAID1 configuration
On installations with fewer than seven nodes, these can be hosted on the system disk of the OSD nodes.
Nodes should be bare metal, not virtualized, for performance reasons.
Mixing OSDs or monitor nodes with the actual workload is not supported.
Configurations may vary from, and frequently exceed, these recommendations depending on individual sizing and performance needs.
Bonded network interfaces for redundancy.
