Common Anti-Virus Agent (CAVA) provides an anti-virus solution to SMB clients by using third-party anti-virus software to identify and eliminate known viruses before they infect files on the storage system. Windows clients require CAVA to reduce the chance of storing infected files on the file system and protects them if they happen to open an infected file. This anti-virus solution consists of a combination of the PowerStore, Common Event Enabler (CEE) CAVA agent, and a third-party anti-virus engine. CAVA is enabled on a per NAS server basis.
PowerStore monitors events and triggers the anti-virus engine to initiate a scan when necessary. Some of the possible event triggers include file renames, modifications, and first reads. While a file is being scanned, access to the file from any SMB client is temporarily blocked. The CAVA solution is for clients running the SMB protocol only. If clients use the NFS or FTP protocols to create, modify, or move files, the CAVA solution does not scan these files for viruses.
CAVA can be customized depending on your specific needs. It can scan specific file extensions, exclude specific file extensions, configure the maximum file size to be scanned, configure the behavior if the anti-virus server goes offline, and more. To ensure that file scanning is maintained if an anti-virus server goes offline or cannot be reached, you should configure at least two CAVA servers.
