- | === 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> | ||
- | |||
- | == 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> | ||
- | |||
- | == 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 ''/ | ||

- | Temporary data (ipfix dumps) is stored in the ''/ | ||
