This page is for “Dell R720xd Server”
Commentary
This Dell R720xd server serves as my primary virtualization host, running Proxmox VE to manage multiple VMs for long-running tasks, particularly those needed for the CodeVigilant project. The server’s 20 physical cores (40 with hyperthreading) and 256GB RAM provide excellent performance for concurrent virtual machines.
The older CPU architecture without AVX2 support initially posed challenges for AI workloads, which led to the creation of my blog post on
Private LLM with no AVX2 server
. However, I’ve since moved AI workloads to a dedicated machine with RTX3060 for better performance.
iDRAC remote management has been invaluable for server administration, especially when configured with a separate IP address for the management interface.
Technical Specs
CPU: Dual Intel Xeon E5-2600 v2 series (10 cores each = 20 physical cores, 40 with hyperthreading)
RAM: 256GB DDR3 ECC memory
Storage: ~4TB total disk space
RAID: Hardware RAID controller support
Network: Dual Gigabit Ethernet ports
Power: Dual redundant 750W power supplies
Form Factor: 2U rack-mount server
Management: iDRAC7 remote management
CPU Limitations: No AVX2 support (older architecture)
Useful Applications
Virtualization
Proxmox VE - Primary virtualization platform (latest ESXi versions don’t support this model)
VMware ESXi - Legacy support only
KVM - Linux virtualization (via Proxmox)
Virtual Machines
CodeVigilant Project VMs - Long-running tasks and services
Development Environments - Isolated development VMs
Testing Environments - Various OS and application testing
Service VMs - Dedicated VMs for specific services
Management and Monitoring
iDRAC7 - Remote server management and monitoring
Proxmox Web Interface - VM management and monitoring
SNMP Monitoring - System health and performance tracking
Tips and Tricks
iDRAC Configuration
Separate IP Address: Configure iDRAC with a dedicated IP address for management interface
Remote Access: Use iDRAC for remote server management and monitoring
Console Access: Access server console remotely for troubleshooting
Virtualization Best Practices
Proxmox VE: Use as primary virtualization platform due to ESXi compatibility issues
VM Resource Allocation: Leverage 20 physical cores (40 with hyperthreading) for optimal VM performance
Long-running Tasks: Dedicate VMs for CodeVigilant project and other persistent workloads
Resource Monitoring: Monitor CPU, RAM, and storage usage across VMs
Hardware Management
RAID Configuration: Set up RAID for data protection and performance
Temperature Monitoring: Monitor temperatures and fan speeds regularly
ECC Memory: Utilize ECC memory for data integrity
Redundant Power: Ensure both power supplies are operational
Firmware Updates: Keep iDRAC and system firmware updated
AI Workload Considerations
AVX2 Limitation: Older CPUs lack AVX2 support, limiting AI model performance
Alternative Solutions: Use dedicated AI hardware (RTX3060) for modern AI workloads
