    -===== 2 Equipment prerequisites ===== 
    -{{indexmenu_n>2}} 
    - 
    -<note important>Do not install the module on the same server with the DPI platform!</note> 
    - 
    -=== Minimum requirements === 
    - 
    -For the subsystem, you can use hardware or virtual machines with the characteristics listed below: 
    -  - Processor (CPU) 2.5 ГГц - 1 pce 
    -  - RAM - at least 16 GB 
    -  - Hard disk drive (SSD is highly desirable) - at least 500 GB 
    -  - Operating system - CentOS 7+ or CentOS 8+ 
    -  - Network interface (NIC) - at least 1 Gbps 
    -<note important>{{ :dpi:dpi_components:capacity_space_for_qoe_and_hardware_example.xlsx |Capacity space for QoE and Hardware example}}</note> 
    - 
    -== Processor == 
    - 
    -SSE 4.2 instruction set support is required. 
    - 
    -Choose processors with a large number of cores. Clock frequency is less important. For example, 16 cores with 2,600 MHz are better than 8 cores at 3,600 MHz. 
    - 
    -<note important>Do not disable Hyper-threading and Turbo-Boost.</note> 
    - 
    -== RAM == 
    - 
    -RAM should be no less than the amount of data requested. 
    - 
    -The more RAM server has, the better performance will be achieved when building reports. 
    - 
    -The more memory, the less disk system is stressing. 
    - 
    -Minimum prerequisites is 16 GB. 
    - 
    -Always disable the swap file. 
    - 
    -== Disk == 
    - 
    -Required disk space is at least 16 GB for every storage day, it's actual value depends on daily traffic. It is estimated that 10 Gbit/s of average daily traffic generates approximately 25 GB of data per hour in the QoE Store. 
    - 
    -If your budget makes you possible to use SSD, use it. Otherwise use HDD. SATA HDDs 7200 RPM will be suitable. 
    - 
    -When using HDD, you can combine them into RAID-10, RAID-5, RAID-6 or RAID-50. 
    - 
    -Most of the data is stored in the ''/var/lib/clickhouse/'' directory. You can mount a drive/partition on this directory. 
    - 
    -Temporary data (ipfix dumps) is stored in the ''/var/qoestor/backend/dump/'' directory. 50 GB be sufficient for this. 
    - 
    -For best performance, it is important (recommended) that these directories are on a separate disk or array. See [[dpi: dpi_components: qoestor: configuration: disc: start | Disk space settings]]

    -=== Maintenance advice from Yandex ClickHouse === 
    - 
    -You could familiarize yourself with the contents of maintenance advice from Yandex ClickHouse by following the [[https://clickhouse.yandex/docs/en/operations/tips/|https://clickhouse.yandex/docs/ru/operations/tips/]] link.
