🚨 Fix Common Problems

Hardware planning troubleshooting! 🔧

Problem 1: Insufficient Memory for Workload

Solution:

# Diagnose memory requirements:
# Check current usage:
free -h
htop
cat /proc/meminfo

# Monitor for 24 hours:
sar -r 1

# Calculate requirements:
# Base OS: 2-4 GB
# Applications: Varies widely
# Buffer/Cache: 20-30% of total
# Safety margin: 25% extra

# Memory sizing formula:
Required = (Base + Apps + Buffers) × 1.25

# Example calculation:
Base OS: 4 GB
Applications: 12 GB
Buffers: 4 GB (25% of 16 GB)
Safety: 5 GB (25% of 20 GB)
Total Required: 25 GB → Round up to 32 GB

# Upgrade recommendations:
# Desktop: 8 GB → 16 GB → 32 GB
# Server: 16 GB → 32 GB → 64 GB → 128 GB
# Database: Start with 64 GB minimum

Problem 2: Storage Performance Bottlenecks

Solution:

# Identify storage issues:
# Check I/O wait times:
iostat -x 1
iotop

# Test disk performance:
# Sequential read test:
dd if=/dev/zero of=testfile bs=1G count=1 oflag=dsync

# Random I/O test:
fio --name=random-write --ioengine=posixaio --rw=randwrite --bs=4k --size=4g --numjobs=1 --iodepth=1 --runtime=60 --time_based

# Performance requirements by use case:
Web Server: 1,000+ IOPS minimum
Database: 5,000+ IOPS for good performance
Virtualization: 10,000+ IOPS recommended
High-frequency trading: 100,000+ IOPS

# Implement storage tiering strategy
# Consider RAID 10 for balanced performance

Problem 3: CPU Performance Issues

Solution:

# Identify CPU bottlenecks:
# Check CPU utilization:
top
htop
mpstat 1

# Monitor per-core usage:
sar -P ALL 1

# Check for thermal throttling:
sensors
cat /proc/cpuinfo | grep MHz

# Performance tuning:
# Set CPU governor to performance:
cpupower frequency-set -g performance

# Check for hyperthreading:
lscpu | grep Thread

# Optimize for workload:
# CPU-bound: More cores, higher frequency
# I/O-bound: Balanced approach
# Memory-bound: Focus on memory subsystem

# Sizing guidelines:
Development: 4-8 cores sufficient
Web server: 8-16 cores recommended
Database: 16-32 cores for large systems
Virtualization: 32+ cores for host servers
HPC workloads: Maximum cores available

Problem 4: Network Performance Limitations

Solution:

# Test network performance:
# Bandwidth test:
iperf3 -c target_server

# Latency test:
ping -c 100 target_server

# Monitor network utilization:
iftop
nethogs
ss -tuln

# Network requirements by use case:
File sharing: 1 Gbps sufficient
Database replication: 10 Gbps recommended
Virtualization: 10-25 Gbps for production
High-frequency trading: 40-100 Gbps

# Optimization strategies:
# Use multiple network interfaces
# Enable jumbo frames (9000 MTU)
# Implement network bonding/teaming
# Consider SR-IOV for virtualization

# Quick configuration:
# Enable jumbo frames:
ip link set dev eth0 mtu 9000

# Check current settings:
ethtool eth0
