The components of a cluster can be distributed in various ways. A typical institution has a Database Server, one or more Archive Servers, one or more Network Gateways, one or more Curators, and one or more Application Servers. Clients are spread throughout the entire enterprise and through remote connection. A single IMPAX cluster can service one or more healthcare facilities and, in such an environment, IMPAX can HIS verify against and access reports from multiple Connectivity Managers for multiple RIS domains.
 | Note: The Archive and Archive Server are the same thing. The archive station is the archive on its own machine. Both are part of the IMPAX cluster. |
Standalone
In a standalone configuration, AS300 Server, Application Server, and Client components are installed on the same computer. The standalone station can be used for diagnostic or non-diagnostic purposes. New installations run under Windows 7 with an Oracle for Windows database. Using VMware Player, the AS300 Server and Application Server components run on Windows 2008 Server. Existing configurations can continue to run under Windows XP and with a SQL Server 2005 or 2008 database. Refer to the IMPAX 6.5.1 Standalone Installation and Configuration Guide or to the IMPAX 6.5.1 Standalone Upgrade Guide.
Single-server
In a single-server configuration, all AS300 Server, Application Server, and Connectivity Manager components are installed on the same Windows computer with an Oracle for Windows database using VMware; Clients are installed on other computers.
All-in-one
In an all-in-one server configuration, all AS300 Server and Application Server components are installed on the same Windows computer with an Oracle for Windows database.
Single-host
In a single-host configuration, the AS300 or AS3000 Server Database, Archive Server, and Network Gateway components are all installed on one “box” or station, with the Application Servers, Clients, and Connectivity Manager each installed on separate stations.
In an AS300 single-host configuration, Curator can also be installed on the same station as the Server components; however, in an AS3000 single-host configuration, Curator must be separately installed. The Curator component runs only on the Windows operating system.
Multi-host
In a multi-host configuration, each Server component is installed on its own station: the Database Server is installed on a separate computer from the Archive Server. The Network Gateway component may either be installed on yet another server, or installed along with the Database Server or Archive Server.
By installing the Server components onto separate stations, workflow volume is better managed and system performance enhanced.
