On December 9, 2002, Symantec Corporation introduced a version of its antivirus software for file server and Internet caching appliances from Network Appliance, Inc.. One of these new products, Symantic AntiVirus for NetApp Filers permits a single anti-virus scanner to monitor and protect multiple file servers, and manages segregation and handling of infected files found. The other new product, Symantec AntiVirus for Network Appliance NetCache performs similar functions on HTTP and FTP traffic. It’s designed to protect companies against virus payloads such as Nimda and Code Red, which can enter networks as attachments to e-mails, active Web content, or downloadable files, and cause infections when saved to disk. As a leading Internet appliance vendor, NetApp’s file server (FAS and Filer products) and NetCache content delivery products are in use in thousands of companies and organizations world-wide.
File servers are important to users who seek to upload or download files across the Internet, using either HTTP or FTP based file transfers, or on local-area networks. These devices make it easy to consolidate data storage and to simplify its data management. Cache servers are designed to store recently- and frequently-used remote content on local devices so that users who return to the same Web pages or other online resources can obtain up-to-date copies of such data locally, rather than having to transfer information across the Internet each time it’s accessed. Whereas file servers provide access to data that may be read or written, and is likely to be explicitly shared among workgroups, cache servers provide access to access that’s likely to be read repeatedly, and is implicitly shared among users on local networks.
