Storage Domain Vservers Owns set of FlexVols Spans multiple physical nodes Logical interfaces (lifs) for end points Transparently migrate between nodes Target for clients CIFS, NFS, FC, FCoE, and Management end point FlexVols Provisioned from underlying RAID by WAFL Integrated snapshots and replication Clone objects Encapsulated in FlexVol Presented as LUN or file Data ONTAP 8 Clustering 12

Sample workflows Create shadow copies of a set of vhdx files using SMB 1. SCVMM layer sends request to Hyper-V 2. Create shadow copy set using file clone operations R-VSS zapi \\vsa\sc_seta 3. SMB share rooted in sc directory Expose, modify, lock SMB vhdx files stored in flat directory \\vsa \\vsa\vhd_shr SMB share rooted in vhdx dir Create app consistent backup on guest Orchestration layer sends request to guest App integrated backup taken using VSS zapi VSS LUN snapshot created on controller 13
