Hardware and software requirements

Recommended hardware requirements

Hardware described below will ensure event-processing capacity of 40,000 events per second. This figure depends on the type of parsed events and efficiency of the parser. Consider also that it is more efficient to have more cores than a lower number of cores with higher CPU frequency.

• Servers to install collectors:
  • CPU: Intel® or AMD™ with at least 4 cores (8 threads) and support for the SSE 4.2 instruction set or 8 vCPU (virtual processors).
  • RAM: 16 GB
  • Disk: 500 GB of available disk space mounted on /opt
• Servers to install correlators:
  • CPU: Intel or AMD with at least 4 cores (8 threads) and support for the SSE 4.2 instruction set or 8 vCPU (virtual processors).
  • RAM: 16 GB
  • Disk: 500 GB of available disk space mounted on /opt
• Servers to install the Core:
  • CPU: Intel or AMD with at least 2 cores (4 threads) and support for the SSE 4.2 instruction set or 4 vCPU (virtual processors).
  • RAM: 12 GB
  • Disk: 500 GB of available disk space mounted on /opt
• Servers to install storages:
  • CPU: Intel or AMD with at least 12 cores (24 threads) and support for the SSE 4.2 instruction set or 24 vCPU (virtual processors).

    Support is required for SSE4.2 commands.

  • RAM: 48 GB
  • Disk: 500 GB of available disk space mounted on /opt

  Using SSDs highly improves cluster node indexing and search efficiency.

  Local mounted HDD/SSD are more efficient than external JBODs. RAID 0 is recommended for faster performance, while RAID 10 is recommended for redundancy.

  To increase reliability, it is not recommended to deploy all cluster nodes on a single JBOD or single physical server (if virtual servers are used).

  To increase efficiency, we recommend keeping all servers in a single data center.

• Machines to install Windows agents:
  • Processor: single-core, 1.4 GHz or higher.
  • RAM: 512 MB.
  • Disk: 1 GB.
  • OS:
    • Microsoft® Windows® 2012.
    • Microsoft Windows Server 2012 R2.
    • Microsoft Windows Server 2016.
    • Microsoft Windows Server 2019.
    • Microsoft Windows 10 (20H1, 20H2, 21H1).
• Machines to install Linux agents:
  • Processor: single-core, 1.4 GHz or higher.
  • RAM: 512 MB.
  • Disk: 1 GB.
  • OS:
    • Ubuntu 20.04 LTS, 21.04.
    • Oracle Linux 8.4.

Software requirements

Each server used to install KUMA services must have the Oracle Linux 8.4 operating system installed.

Network requirements

The network interface bandwidth must be at least 100 Mbps.

For KUMA to be able to process more than 20,000 events per second, ensure a data transfer speed of at least 10 Gbps between ClickHouse nodes.

Additional requirements

For computers used for the KUMA web interface, Google™ Chrome™ browser version 93 or later, or Mozilla™ Firefox™ browser version 92 or later must be installed.
