In reply to Reefe.

No question that it's all about the software, Reefe. If I'm not mistaken ext4 is the basis for NDFS/NOS. In that sense it's not really built from the ground up, but the evolution of a pre-existing write-in-place file system. We think the type of log structured filesystem we have in HyperFlex conveys a lot of benefits in terms of in-line dedupe and compression and better endurance for flash.
