1. AUD Server Installation Environment

AUD Server is the main server providing DB Connection Management, Administrator, Repository, and Manager features.

i-META Server and i-OLAP Server are installed with the AUD Server in default.

1.1 Hardware

OS	UNIX	IBM AIX (7.1 TL5 or higher), SunSolaris (9 or higher)	Supported OS
	LINUX	RedHat, CentOS (7.x or higher), Ubuntu (18.x or higher)
	NT	Windows Server 2008 or higher
CPU	Based on 100 Users and 10 Concurrent Users At least 4 Core May vary depending on the total number of users, concurrnet users etc.
Memory	Minimum: 16G (for dedicated use of the AUD Server) Recommended: 64G or higher (May vary depending on factors such as unstructured analysis, number of concurrent users, and Data Size)
Storage	Screen Files : 2M * 1,000ea * 10(for Backup/Restore files) = 20G tmp area (Olap Cache file, Export etc.) : 30G → Recommend Sized for reports (Shared Storage is required for screen section and high availability setup) : 50G or more Log Files : 100M/month, 1G per year by default Total AUD Server Installation Size (including Source Code) : At least 10G Actual storage usage may vary depending on the number and complexity of created screens

Runtime environment necessary to operate the AUD Server.
Supported JDK Versions : 1.8 ~ 11 (* Versions above 11 may not function properly.)

WAS Types	Weblogic, Tomcat, Jboss, etc.
Required Space	10G (For installing AUD Server Source, including the management UI Source images, Increase depending on the number and complexity of screens to create)

DBMS Type	Commercial DBMS	Oracle / Exadata	9i or higher
		MS-SQL	2008 or higher
		DB2	8.x or higher
		Tibero	4.x or higher
		Teradata	14.x or higher
		RedShift	-
	Open-Source DBMS	MySQL / MariaDB	5.x or higher
		Cubrid	8.x or higher
		PostgreSQL	9.x or higher
Storage Requierments		Initial Data Size : 1G 5G for each Log Table (including estimated annual cumulative buffer size)

i-META Server is for creating and managing META.

i-META Server is installed along with the AUD Server by default, but it requires the below installation environment if deployed on a seperate server.
When the i-META Server is deployed separately, integration with the AUD Server is required.

OS	Window Server 2008 or higher (64 bit) Linux (64 bit) RedHat, CentOS, Ubuntu UNIX IBM AIX (OS 7.1 or higher, Service Pack TL5 or higher) ※ LINUX Recommended ※ Sun Solaris / hp Not Supported (META Server based Node.js does not support the OS)
CPU	At least 2 Core Recommend 4 Core or more
RAM	At least 8G Recommend 16G or more
HDD	At least 5G Recommned 10G or more 4G * 4 Core + Total Data Size(Current) + 50% available space

For IBM AIX Server, a minumum system requirement is required to install the i-META Server, as Nodejs (Open Source) is used to ensure user convenience and optimal performance.
If an older version of IBM AIX is being used,
it is recommended to either use a separate server that meets the installation requirements (4Core, 16G) or upgrade the Operating System.
If these conditions are not met, a lower version of i-META (not the latest) may need to be used.

i-OLAP Server is for i-AUD Olap-Grid Pivot Data Handling.

i-OLAP Server is installed along with the AUD Server by default, but it requires the below installation environment if deployed on a seperate server.
When the i-OLAP Server is deployed separately, integration with the AUD Server is required.

OS	Window Server 2008 or higher (64 bit) Linux (64 bit) RedHat, CentOS, Feodra, Debian, Ubuntu, SUSE UNIX IBM AIX, HP-UX, Sun Solaris ※ LINUX Recommended
CPU	At least 4 Core Recommend 8 Core or more
RAM	At least 16G Recommend 64G or more (Based on 10 concurrent users, 1 million records, and 20 columns)
HDD	At least 256G Recommend 500G or more Varies depending on the amount of analysis data (an additional 50% of the data size should be allocated for storage)
