Distributed workload state

7

Workload Domain • Application in-core buffers • Guest OS & file system state

Hypervisor Domain • Guest scheduling and resources • VMFS and CSV state

Storage Domain • Guest direct connect storage • Hypervisor sourced storage (P4V)


Guest point-in-time consistency

8

Crash consistency • Snapshot of a naïve guest’s storage resource Hibernation consistency • Put the guest to sleep and then snapshot Application consistency • Place the app in a backup state • Flush the file system and snapshot

Application specific APIs Customized distribution and FS integration • SAN and/or NFS

Application specific APIs Volume Shadow copy Service (VSS) • Integrated NTFS and application backup snapshot • Remote VSS for SMB shares

Application consistent snapshot backups

Data ONTAP™ 8 Clustering

FlexVols • Provisioned from underlying

RAID storage by WAFL • Integrated snapshots and

replication

Vservers • Owns set of FlexVols • Spans multiple physical nodes • Logical interfaces (lifs) for end points

• Transparently migrate between nodes • Target for storage clients

• CIFS, NFS, FC, FCoE, and iSCSI • Management end point

Clone objects • Encapsulated in FlexVol • Presented as LUN or file


Sample workflows

Create app consistent backup on guest

zapi

App integrated backup taken using VSS

VSS LUN snapshot created on controller

iSCSI

Remote

1. SCVMM layer sends request to Hyper-V

vhdx files stored in flat directory R-VSS zapi

2. Create shadow copy set using file clone operations

\\vsa\sc_setA

3. SMB share rooted in sc directory Expose, modify, lock

\\vsa\vhd_shr SMB share rooted in vhdx dir

Orchestration layer sends request to guest

Create shadow copies of a set of vhdx files using SMB
