NetApp SMVI 2.0 - VMworld Mini Theatre
SnapManager for Virtual Infrastructure 2.0 automates snapshot-based backups and disaster recovery for virtualized VMware environments stored on NetApp storage systems. It addresses challenges of virtual infrastructures like increasing storage demands and slow traditional backups. SMVI leverages NetApp snapshot technology to provide instantaneous, storage-efficient backups and fast restores. It simplifies data protection management and improves recovery time and point objectives.

Editor's Notes
- #3 Goal of this slide: Emphasize that storage deployed in virtualized environments needs to be robust.Points:Server virtualization indeed allows dramatic levels of server consolidation, often in the range of 10:1. This gets over the old “silo” of one app = one server.A storage failure in a server now takes down 10 applications, not just one. (need more reliable storage)A dual-disk failure (or more commonly, a failure with a media error on rebuild) means that data sets of 10 apps have to be reloaded, not just one. (need something better than RAID 5)With 10X more data on a server, may not be able to make the backup window. (need faster backup)In addition, with the ever-increasing criticality of IT operations, disaster recovery continues to increase in priority. DR is very difficult in a DAS environment, but becomes practical with virtualized servers and storage-based DR.While server virtualization enhances server provisioning greatly, the result is fast server and slow storage provisioning, unless other means of storage provisioning are brought into the picture.
- #9 Goal of this slide: Illustrate the sequence of backup operationsPoints:The virtual administrator requests a backup of VM1 and VM2 Virtual Center communicates with the appropriate ESX server which will place VM1 and VM2 in “Hot Backup” modeRedo-Logs get created by VMware for these VMs and the VMDKs are now frozen and all writes happen on the Redo-Logs for these Virtual Machines.SnapManager for VI can now initiate Data ONTAP Snapshots via the ONTAP APIs and the Snapshot of the entire datastore where these Virtual Machines reside is taken.Once the ONTAP Snapshot is completed, SnapManager for VI informs VC to take these VMs from the “Hot-Backup” mode and the Redo-Logs are applied to their corresponding VMDK(s) and normal operation resume

- #13 Goal of this slide: Leave them with the possibilities that apply directly to an overall virtualization deployment and can be provided by NetApp storagePoints:Self-explanatory points, all of which are addressed earlier in the presentation.This slide should address both audiences: (1) the customer who is still using DAS storage and has not yet adopted network-based storage, as well as (2) the customer who has adopted (or will be purchasing) networked storage but does not yet understand the NetApp advantages.
