Dualog Connection Suite - System Requirements


Dualog Connection Suite consists of a standard package plus optional extensions. This document describes the requirements of different configurations of Dualog Connection Suite, as well as software requirements/support. This document is valid from Dualog Connection Suite version 3.0 and onwards.


Please note that these requirements are a minimum.
IMPORTANT: If other applications are running on the same computer as Dualog Connection Suite, higher CPU, memory, and disk capacity apply.

The following requirements apply when running the Dualog Connection Suite Core service only:

CPU Intel® Core™ i3 or equivalent
RAM Minimum 2 GB (recommended 4 GB)
DISK SPACE The installation itself takes approx. 50 GB. In addition data storage (e-mail, log files, File Transfer, database, etc) must be added. HQ graded server disks are highly recommended.
I/O Serial Ports, Network Adapters according to communication equipment requirements.



When using the email services (Business Mail and Crew Mail), no further requirements apply to CPU and RAM, while disk requirements will increase. On average, the email services generates approx. 20 GB per year, while backup will add up this space multiplied by 4.


To avoid reduced throughput on internal traffic, a CPU with at least four cores is required. The following minimum HW recommendations apply:

CPU Intel® Core™ i5-2300+ or equivalent
DISK SPACE Network Control stores data in the Oracle database, with no specific HDD requirements
I/O A minimum of two network interfaces: one connecting the ship’s LAN and the other to the communications equipment.

(*)We do not recommend Connection Suite installations on a Windows Server that is also a domain controller.

In all server versions, we recommend that tests and pilots are done before a production rollout, as we are not able to guarantee that all architecture designs will provide the same results.


The user interface in Connection Suite is mainly a Non-Flash based webpage and can be accessed via any computer connected to the ship's LAN. The following browsers are tested and highly recommended. 

Microsoft Edge (Chromium) Latest version available
Mozilla Firefox Latest version available
Google Chrome Latest version available


Important note: For user log-in and usage of the Internet, Quota Management, and CrewMail (Webmail), HTML5 is supported. Therefore, tablets and smartphones may be used by ship staff to access Connection Suite Services.
