How to create cluster with HA and redundancy, etc, with OPi

Hi all,

 

I'm puzzled how everybody is building clusters of cheap SBC's, but nobody is implementing HA, redundancy, resiliency, failover, etc.  They're just SBC's networked together.  The SBC's are underprovisioned for Ceph, so I think that even if a Ceph configuration was managed to be shoehorned in, it wouldn't perform well.  I don't know if DRDB is an option.

 

How are people actually doing implementing real clustering technology on Orange Pi, for example?  I'm using OPi+2E.

 

Kind regards,

Andrew
