Write Anywhere File Layout
- Write Anywhere File Layout

Write Anywhere File Layout (kurz: WAFL) ist ein Dateisystem, das von NetApp für deren Massenspeichersysteme unter dem Einsatz des Betriebssystems Data Ontap entwickelt wurde. Es hat eine Verwandtschaft zu UNIX-Dateisystemen, wie dem Berkeley Fast File System und Transarcs Episode File System.
WAFL wurde beim Design für Netzwerk-Dateizugriffe optimiert, Fähigkeiten wie eine unterbrechungsfreie Vergrößerung eines Dateisystems wurden daher schon von Grund auf implementiert.
