Software and Hardware Recommendations

About

As an open source distributed NewSQL database with high performance, TiDB can be deployed in the Intel architecture server and major virtualization environments and runs well. TiDB supports most of the major hardware networks and Linux operating systems.

Linux OS version requirements

Note:

• For Oracle Enterprise Linux, TiDB supports the Red Hat Compatible Kernel (RHCK) and does not support the Unbreakable Enterprise Kernel provided by Oracle Enterprise Linux.
• A large number of TiDB tests have been run on the CentOS 7.3 system, and in our community there are a lot of best practices in which TiDB is deployed on the Linux operating system. Therefore, it is recommended to deploy TiDB on CentOS 7.3 or later.
• The support for the Linux operating systems above includes the deployment and operation in physical servers as well as in major virtualized environments like VMware, KVM and XEN.

Server recommendations

You can deploy and run TiDB on the 64-bit generic hardware server platform in the Intel x86-64 architecture. The requirements and recommendations about server hardware configuration (ignoring the resources occupied by the operating system itself) for development, test, and production environments are as follows:

Development and test environments

Note:

• In the test environment, the TiDB and PD instances can be deployed on the same server.
• For performance-related test, do not use low-performance storage and network hardware configuration, in order to guarantee the correctness of the test result.
• For the TiKV server, it is recommended to use NVMe SSDs to ensure faster reads and writes.
• The TiDB server uses the disk to store server logs, so there are no special requirements for the disk type and capacity in the test environment.

Production environment

Note:

• In the production environment, the TiDB and PD instances can be deployed on the same server. If you have a higher requirement for performance and reliability, try to deploy them separately.
• It is strongly recommended to use higher configuration in the production environment.
• It is recommended to keep the size of TiKV hard disk within 2 TB if you are using PCIe SSDs or within 1.5 TB if you are using regular SSDs.

Network requirements

As an open source distributed NewSQL database, TiDB requires the following network port configuration to run. Based on the TiDB deployment in actual environments, the administrator can open relevant ports in the network side and host side.

Web browser requirements

TiDB relies on Grafana to provide visualization of database metrics. A recent version of Internet Explorer, Chrome or Firefox with Javascript enabled is sufficient.
