# System Requirements

This article describes the system requirements both for the server on which the analyses are executed as well as on the users' side.

# System Requirements for Analysis Server

The Teamscale server can be installed on both Linux and Windows machines and has the following minimum requirements:

Operating System:
- Linux recommended with glibc >= 2.15 and glibc++ >= 3.4.22 (e.g., Ubuntu 2018.04 or RHEL 8)
- Windows with Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019
Java: Java Runtime Environment (e.g., Oracle Server JRE or OpenJDK), Version 11 or later, 64-bit
CPU: 2 GHz, 2 or more cores recommended
RAM: 4 GB minimum
Disk Space:
- Installation: 250 MB
- Data: at least 10 GB
  Disk Space
  
  The disk space requirements for data highly depend on the amount of source code of the analyzed software, the time range of the history being analyzed, and the commit behavior, i.e., the frequency and number of committed files, within the time range analyzed.
  
  Hard Drive Performance
  
  We highly recommend using a local SSD. For large code bases (> 1 MLOC), a local SSD with high IOPS numbers is required. In these scenarios, network-attached storage will usually not be sufficiently performant. To verify your disk performance, please measure the I/O performance of your disks with fio and compare it to our reference table.

Sizing Example

As an example, a system of about 500 kLOC and a history of 1.5 years requires about 1 GB of disk space.

Here are the requirements for Teamscale users who want to use one of the Teamscale IDE plugins:

Eclipse: Eclipse SDK 4.4.2 (Luna SR2) or later, running on Java 8 or later
Visual Studio: Visual Studio Version 2015 or later, .NET Framework 4.5 or later, Windows Vista or later
IntelliJ: 2019.1 or later
NetBeans: 8.1 or later, running on Java 8 or later
