System Requirements


Any hardware system capable of running a supported version of Microsoft Windows with the minimum RAM recommended for your operating system. Upgraded RAM quantity will increase imaging performance.


Viking products can be installed on any network file server that can provide file services to remote Microsoft Windows-based workstations. These include Windows, Novell, and UNIX systems (using SMB protocol) among others. For thin client installations, remote users can access the server over the Internet with a CITRIX or Microsoft Remote Terminal Server.


A 10 Mbit/s network is fast enough because VDE only uses the network when the program opens or closes a data file and when the journal file is flushed every few minutes.

Storage Capacity

Storage requirements are minimal for data entry batch files, which tend to be small and have a short residence time. As a guideline, assume each operator will generate 100 KB per day. Multiply this by the number of days you will keep the data files on your server to determine the storage capacity requirement.
