• Database Server hosting the SQL database
The database used by the IMPAX 6.3 AS300 cluster. It collects, organizes, and manages all patient
and study demographic data that is contained in DICOM header files.
• Network Gateway
Workflow manager of the IMPAX 6.3 AS300 cluster. It receives studies from modalities and
provides DICOM security and validation. Installation and configuration of a Windows-based
Network Gateway is covered in this guide.
• Archive Server
DICOM archive used for permanent storage and retrieval of studies. This component runs on a
Windows server. Installation and configuration of a Windows-based Archive server is covered in
this guide.
• Application Server
Clients connect to one or more Application Server machines, which act much like a proxy machine
to handle security, authentication, and communication with the IMPAX 6.3 Server components.
Installation and configuration details are covered in the
IMPAX 6.3 Application Server Installation
and Upgrade Guide
and
IMPAX 6.3 Application Server Configuration Guide
.
• Curator
Clients can view JPEG compressed or wavelet compressed DICOM images generated by the
Curator. Installation and configuration details are covered in the
IMPAX 6.3 Curator and CD Export
Server Installation Guide
.
• Clients—Local and Remote
Multi-modality diagnostic or clinical display station for viewing images and diagnosing studies.
Installation and configuration details are covered in the
IMPAX 6.3 Client Installation and
Configuration Guide
and the
IMPAX 6.3 Client Configuration Guide.
Also possible is installing all components on one Windows computer—the standalone configuration.
That option is covered in the
IMPAX 6.3 Standalone Installation, Upgrade, and Configuration Guide
.
Another possible configuration is when all components other than Clients are installed on one computer,
along with the Connectivity Manager software and database—the single-server configuration. This
option is covered in the
IMPAX 6.3 Single-Server Installation and Configuration Guide
.
The sum of these components is called the
cluster
. The IMPAX 6.3 AS300 cluster is the set of core IMPAX
6.3 AS300 components that run on the Windows operating system and are controlled by one SQL
database. The Database Server must be installed first because the other stations must connect to the
SQL database.
Understanding cluster configuration options
Database, Archive, and Network Gateway components can all be installed on one “box” or station. This
is called a single-host configuration. For larger sites, each component may have its own station. This
is known as a
multi-host configuration
. By loading the IMPAX 6.3 Server software modules onto separate
stations, workflow volume is better managed and system performance enhanced. An intermediary
option is to install the Database Server on one station, and the Network Gateway and Archive Server
together on another station.
