The choice between either depends on what you're doing. Personally I try to do everything with NFS and avoid using LUNs where I can for flexibility reasons.</P></BODY></HTML> Thu, 18 Nov 2010 23:30:36 GMT https://community.netapp.com/t5/ONTAP-Discussions/Which-Offers-Better-Deduplication/m-p/72074#M16776 brendanheading 2010-11-18T23:30:36Z
