Conclusion

We have looked at a period of enormous changes looming in computer storage. The results can only be described as a revolution. Technologies are migrating rapidly from 50-year-old spinning disks to all solid-state solutions that are much faster and robust, whereas on the software side, we are entering a period of virtualized data services that are no longer pinned to the underlying hardware.
Connectivity is rapidly moving to Ethernet and away from Fibre-Channel. Scale-out storage more and more means object storage, but in the end the concept of universal storage boxes that handle all protocols will be the winning approach. NVMe will replace both SAS and SATA, simply because it is a faster protocol that uses much less host compute power. ...
