Navision Architecture –2-Tier

· Microsoft Navision is a two-tier solution application.
· It consists of a Database Management System (DBMS) that resides on the server and a Graphical User Interface (GUI) that resides on the client.
· You can also configure the client to be a stand-alone installation, which means that the client functions as a server and a single client in one.


Navision Architecture –N-Tier

· The Navision Application Server (NAS) is a middle-tier server that supports an n-tier architecture, which executes business logic without user intervention.
· Microsoft Navision Application Server allows you to communicate with external services.
· Microsoft Navision Application Server acts as a client towards a database server and can act as a server for other services.
· Microsoft Navision Application Server can communicate with both Microsoft Navision Database Server and the SQL Server Option in the same way as a Microsoft Navision client.



Processor and Memory Subsystems

· Does it matter?

Yes it does matter, the lower the RAM the lower the processing speed, you can find more information in this section later.

· Single or Multiple Processors?

NAV supports both single and multiple processor but obviously a Multiple server does add to the processing power compared to the single processor.

· How much RAM should I use or buy?

On the server NAV recommends 2GB of RAM, the client computers can be <128Mb.

The bigger question-Bandwith?

Its like a road with busses some join in in the middle, so <64Kbps is what can be recommended. This also hold true for your VPN implementation for the ERP (NAV) package

RAID

You can go ahead with RAID 1+0, if you want more information on the levels of RAID then you can follow the link
