{ “title”: “Hardware and Software Environment Check”, “language”: “en”, “description”: “Before deploying Doris, check the hardware configuration, server specifications, disk space, and Java environment.” }

This document provides a hardware and software environment reference for deploying Doris.

Hardware environment check

Check item	Minimum configuration	Recommended configuration
CPU	Supports the AVX2 instruction set	Supports the AVX2 instruction set
Memory	CPU cores x 4 GB	CPU cores x 8 GB
Storage	SSD or HDD	SSD
File system	ext4 or xfs	ext4 or xfs
Network card	1GbE	10GbE + link aggregation

CPU check

Doris uses AVX2 vectorization to accelerate queries. A machine that supports the AVX2 instruction set is recommended.

cat /proc/cpuinfo | grep avx2

If there is output, AVX2 is supported. If it is not supported, you can use the no-AVX2 Doris installation package.

Memory check

Doris does not enforce a memory limit. The following is recommended for production environments:

Component	Minimum memory	Recommended memory
FE	16 GB	64 GB+
BE	CPU cores x 4 GB	CPU cores x 8 GB

Storage check

Scenario	Recommended storage type
High-concurrency point queries on large-scale data	SSD
High-frequency updates on large-scale data	SSD
Cold data archiving	HDD / object storage

File system check

File system	Applicable scenario
ext4	General-purpose, good stability
xfs	Large-scale data, high-concurrency writes

Network card check

A 10GbE or faster network is recommended. For machines with multiple network cards, use link aggregation to improve bandwidth and redundancy.

Recommended server configuration

Both x86-64 and ARM64 architectures are supported.

Development and test environments

FE and BE can be deployed together:

• Deploy 1 FE + 1 BE on a single server (multiple instances are not recommended)
• For 3 replicas of data: deploy 1 BE on each of at least 3 servers

Module	Minimum CPU	Minimum memory	Minimum disk	Network	Instances
Frontend	8 cores	8 GB	SSD/SATA, 10 GB+	1GbE/10GbE	1
Backend	8 cores	16 GB	SSD/SATA, 50 GB+	1GbE/10GbE	1

Production environment

It is recommended to deploy FE and BE separately. When resources are tight and they must be co-located, place their data on different disks.

Module	Recommended CPU	Recommended memory	Recommended disk	Network	Instances
Frontend	16 cores+	64 GB+	SSD, 100 GB+	10GbE	1
Backend	16 cores+	64 GB+	SSD/SATA, 100 GB+	10GbE	3

Disk space calculation

Component	Recommended space	Description
FE	100 GB+	SSD, used for metadata storage
BE	Total data volume x 3 x 1.4	LZ4 compression ratio 0.3-0.5, 3 replicas + 40% reserved space for background compaction

The BE storage calculation above is mainly for the integrated storage and compute deployment mode. In the separated storage and compute deployment mode, all data is stored in shared storage, and the local disk is used only for caching, so the disk size depends on the size of the hot data.

Java environment check

All Doris processes depend on Java.

Doris version	Java version	Recommended version
2.1 (inclusive) and earlier	Java 8	jdk-8u352+
3.0 (inclusive) and later	Java 17	jdk-17.0.10+
