In an ideal world, your high-performance primary tier is used exclusively for active files.  Yet in practice, up to 80% of file data becomes stale but continues to reside in expensive primary storage.  DefendX Software’s VFM can help you reduce storage costs through powerful and flexible file data tiering and archiving.  It helps you avoid the “server sprawl” that happens when you continually purchase more hardware and capacity ― after all, not all of your file data is of equal importance.
