Choosing Your Array Type Need or System Use Transaction server Video server Web server Definition Users at multiple PCs randomly access the server mostly for creating new files and for updating old ones (for example, hospital or banking applications), making data availability critical; requires high random-read performance and fault tolerance. Users transfer large blocks of sequential data from the server, edit the data, and return the data to the server; requires high sequential-read and -write performance. Users log in to the server to locate and view information. Sometimes they enter data such as registration information or transfer data if an FTP site allows it.
