Production Environment Hardware Configuration Guide

1. Deployment Planning Factor Analysis

Before formally deploying RustFS, it's recommended to conduct 2-3 weeks of business research, focusing on evaluating the following dimensions:

1. Data Scale Analysis

• Initial Data Volume: Accurately calculate effective data volume at production startup (recommended in TiB units), considering hot/cold data ratios
• Growth Trend Prediction: Estimate data increments for the next 24 months based on business development plans (recommended quarterly growth rate model)
• Object Scale: Calculate total object count based on average object size (recommended 128 KB-1 MB range), note special optimization needed when exceeding 100 million objects

2. Business Characteristic Assessment

• Access Patterns: Distinguish read-intensive (such as content distribution) from write-intensive (such as log collection) scenarios
• Compliance Requirements: Data retention cycles must comply with industry regulatory requirements (e.g., financial industry must retain for at least 5 years)
• Multi-site Deployment: Cross-regional deployment requires network latency assessment (recommended controlled within 50ms) and bandwidth cost evaluation

3. Storage Architecture Design

• Bucket Planning: Divide storage buckets by business units, single cluster recommended not exceeding 500 active buckets
• Disaster Recovery Strategy: Choose dual-active architecture (recommended) or asynchronous replication based on data importance

2. Hardware Configuration Matrix

Baseline configuration solutions based on stress test results:

Component	Basic Environment	Production Standard Configuration	High-Performance Configuration
Node Count	4 nodes	8 nodes	16+ nodes
Storage Media	4× NVMe SSD	8×NVMe SSD	12×NVMe SSD
Network Architecture	Dual 25GbE (link aggregation)	Dual 100GbE	200GbE
CPU	2×Intel Silver 4310 (16 cores)	2×AMD EPYC 7313 (32 cores)	2×Intel Platinum 8461Y (48 cores)
Memory	64 GB DDR4-3200 ECC	256 GB DDR5-4800 ECC	512 GB DDR5-5600 ECC
Storage Controller	HBA 9500-8i	HBA 9600-16i	Dual controller redundant architecture

Important Deployment Principles:

1. Adopt "server farm" mode, ensuring all nodes use identical hardware batches and firmware versions
2. Network architecture must meet: leaf-spine topology + physically isolated storage network + dual uplink paths
3. Recommend using 2U server models, single node recommended configuration of 12+ disk bays (based on actual hard disk count)

3. Performance Critical Path Optimization

1. Network Topology Optimization (Highest Priority)

• Bandwidth Calculation: Reserve 0.5 Gbps bandwidth per TB of effective data (e.g., 100 TB data needs 50 Gbps dedicated bandwidth)
• Latency Requirements:
• Inter-node P99 latency ≤ 2ms
• Cross-rack latency ≤ 5ms

2. Storage Subsystem Tuning

• Controller Configuration:
• Enable read-ahead cache (recommended 256 MB+)
• Disable all RAID functions, use pass-through mode
• Regularly check BBU battery health status
• SSD Parameters:
• Reserve 20% OP space to improve durability
• Enable atomic write features (requires hardware support)

3. Memory Management Strategy

• Allocation Ratios:
• Metadata cache: 60% of total memory
• Read/write buffers: 30%
• System reserve: 10%

4. Network Design Reference Model

Bandwidth and Disk Ratio Relationship

Network Type	Theoretical Throughput	Suitable Disk Types	Maximum Disk Support
10GbE	1.25 GB/s	7.2K HDD (180 MB/s)	8 disks
25GbE	3.125 GB/s	SATA SSD (550 MB/s)	6 disks
100GbE	12.5 GB/s	NVMe Gen4 (7 GB/s)	2 disks full-speed read/write

Best Practice Case: A video platform uses 16-node cluster, each node configured with:

• 8×7.68 TB NVMe SSD
• Dual 100GbE CX5 network cards
• Achieves aggregate throughput of 38 GB/s

5. Memory Configuration Calculator

Dynamic algorithm based on disk capacity and business characteristics:

# Memory calculation formula (unit: GB)
def calc_memory(data_tb, access_pattern):
 base = 32 # Base memory
 if access_pattern == "read_heavy":
 return base + data_tb * 0.8
 elif access_pattern == "write_heavy":
 return base + data_tb * 1.2
 else: # mixed
 return base + data_tb * 1.0

Reference Configuration Table:

Data Scale	Read-Intensive	Write-Intensive	Mixed
10 TB	40 GB	44 GB	42 GB
100 TB	112 GB	152 GB	132 GB
500 TB	432 GB	632 GB	532 GB

6. Storage Deployment Standards

1. Media Selection Criteria

Metric	HDD Suitable Scenarios	SSD Suitable Scenarios	NVMe Mandatory Scenarios
Latency Requirements	>50ms	1 to 10ms	< 1ms
Throughput Requirements	< 500 MB/s	500 MB-3 GB/s	> 3 GB/s
Typical Use Cases	Archive storage	Hot data cache	Real-time analysis

2. File System Configuration

# XFS formatting example
mkfs.xfs -f -L rustfs_disk1 -d su=256k,sw=10 /dev/sdb

# Recommended mount parameters
UUID=xxxx /mnt/disk1 xfs defaults,noatime,nodiratime,logbsize=256k 0 0

7. High Availability Assurance Measures

1. Power Supply:

• Adopt dual power supply architecture
• Each PDU connects to different substations
• Equip UPS (at least 30 minutes runtime)

2. Cooling Requirements:

• Cabinet power density ≤ 15kW/cabinet
• Inlet/outlet temperature difference controlled within 8℃

3. Firmware Management:

• Establish hardware compatibility matrix
• Use unified firmware versions

Implementation Recommendations: Recommend conducting 72-hour stress testing before formal deployment, simulating the following scenarios:

1. Node failover testing
2. Network partition drills
3. Burst write pressure testing (recommended reaching 120% of theoretical value)
