Production Environment Hardware Configuration Guide

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

Hardware Configuration Matrix

Baseline configuration solutions based on stress test results:

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)

Performance Critical Path Optimization

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

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)

Memory Management Strategy

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

Network Design Reference Model

Bandwidth and Disk Ratio Relationship

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

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

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

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)
