System requirements#
In order to guarantee the operation of all functionalities of i-doit, some requirements must be met by the underlying system.
Current version
The requirements shown below apply to the current version of i-doit, in this case 22. These requirements are adjusted for each major release of i-doit. If the requirements of older versions are needed, the change history of this page can be used.
Minimum Requirements#
The following system parameters are the minimum requirements to guarantee i-doit to work with up to around 10,000 objects and up to 10 users working simultaneously.
Virtual Hardware#
- 2 vCPUs
- 2 GB RAM
- 10 GB free disc space
We recommend the use of a dedicated virtual machine. The actual demand for hardware is based on the scope of the IT documentation and the amount of simultaneous users.
Operating System#
- Debian GNU/Linux 10 "buster", 11 "bullseye"
- Ubuntu 18.04 LTS "bionic", 20.04 LTS "focal fossa"
- SUSE Linux Enterprise Server (SLES) 15, 15 SP1, 15 SP2, 15 SP3
- Red Hat Enterprise Linux (RHEL) 7, 8
- Microsoft Windows Server 2016, 2019
We recommend the usage of Debian GNU/Linux in 64bit architecture (amd64) in version 11 "bullseye".
LAMP Stack#
- Apache Web server 2.4
- MariaDB 10.2, 10.3, 10.4, 10.5 (recommended) or MySQL 5.7. But we highly recommend to use MariaDB instead of MySQL. __When version 10.6 is marked as stable we plan to support it in a later release.
- PHP >= 7.4, 8.0 (recommended) At the moment, PHP version 8.1 is not supported. We plan the support of PHP 8.1 in a later release.
- PHP extensions: bcmath, ctype, curl, fileinfo, gd, imagick, json, ldap, mbstring, memcached, mysqli, mysqlnd, pgsql, session, soap, xml, zip
We recommend the usage of Apache Webserver 2.4, PHP 8.0 and MariaDB 10.5.
Success
The following system parameters comprise a configuration reference that is tested and recommended by us and guarantees high performance when used with up to 500,000 objects and a high number of simultaneously working users.
Virtual Hardware#
- 2 vCPUs
- 8 GB RAM
- 50 GB free disc space
Operating System#
Debian GNU/Linux 10 "buster" (64bit)
LAMP Stack#
- Apache 2.4.x (default package)
- MariaDB 10.3.x (default package)
- PHP 8.0.x (default package)
Note
Because i-doit is a database application, it intensively uses the hard drive. Since the I/O throughput strongly determines the performance, a fast hard drive is recommended.
The need for disc space can increase with intense usage of file or image storage in i-doit.
The value of 50 GB is solely geared to the maximal size of the database, which can be achieved by full usage, updates and similar operations.
Client#
A Web browser is needed on the client side in order to access the Web GUI of i-doit. For each Web browser the current version as well as the version prior to this are supported:
- Mozilla Firefox (including the last ESR version)
- Google Chrome/Chromium
- Microsoft Internet Explorer/Edge (disabled compatibility mode)
- Apple Safari
