Ceph is not becoming Spectrum Ceph. Along with ODF, it will remain 100 percent open source. IBM said it will assume Premier Sponsorship of the Ceph Foundation, whose members collaborate on the Ceph open source project.
That is the key take-away for me that I hope remains true and does not go the route of Sequent. Should that be the case I also hope the Ceph Foundation keep Ceph alive and independent from IBM perhaps by forking it in the same manor that was done with MySQL (MariaDB and others) when Oracle acquired it.
