You can use integrated antivirus functionality on the storage system to protect data from being compromised by viruses or other malicious code. ONTAP virus scanning, called Vscan, combines best-in-class third-party antivirus software with ONTAP features that give you the flexibility you need to control which files get scanned and when.
Storage systems offload scanning operations to external servers hosting antivirus software from third-party vendors. The ONTAP Antivirus Connector, provided by NetApp and installed on the external server, handles communications between the storage system and the antivirus software.

You can use on-access scanning to check for viruses when clients open, read, rename, or close files over SMB. File operation is suspended until the external server reports the scan status of the file. If the file has already been scanned, ONTAP allows the file operation. Otherwise, it requests a scan from the server.
On-access scanning is not supported for NFS.

You can use on-demand scanning to check files for viruses immediately or on a schedule. You might want to run scans only in off-peak hours, for example. The external server updates the scan status of the checked files, so that file-access latency for those files (assuming they have not been modified) is typically reduced when they are next accessed over SMB.
You can use on-demand scanning for any path in the SVM namespace, even for volumes that are exported only through NFS.
You typically enable both scanning modes on an SVM. In either mode, the antivirus software takes remedial action on infected files based on your settings in the software.
Virus scanning in disaster recovery and MetroCluster configurations For disaster recovery and MetroCluster configurations, you must set up separate Vscan servers for the local and partner clusters. |
