Hi
Detailed Documentation: 3BSE038018-510_H_en_System_800xA_5.1_System_Guide_Functional_Description
Connectivity Server: Provides Dynamic Data like OPC DA, etc
Aspect Server: Provides Static Data like Graphical elements, libraries, objects, etc.

Hi,
The 800xA system provides a functional building block approach for system design to meet every system application need. The base system includes the Aspect Server that provides the aspects used to configure an operational system. As new functions are added to the system, aspects associated with the new functions are added to the Aspect Server providing a single configuration database for the system, ease of system set-up and operation, and the ability to easily migrate small system installations to larger system configurations by adding on functional options.
Connectivity Server, provide access to controllers and other data sources. Several groups of connectivity servers may exist in a system, each serving one set of data sources. Examples of services that run on a connectivity server are OPC related services (DA, AE, and HDA), and SysMsg
According to your total I/O number, you can combine Aspect Server and Connectivity Server. If you have huge number of total I/Os, you have to seperate it.
For more details, please see attached file.
Hope this helps you.
The aspect server (or servers) holds the aspect system. This is where all the information is stored, the "intelligence" of 800xA. The connectivity server (or servers) provide you with real time data from different sources. All clients use data from both servers to build the human interface.
I would recommend to attend a basic course of 800xA. If this is not possible you may start with some documents from the ABB Library:
3BSE034678 Manual Installation
3BDS011222 Configuration
