The Past, Present, and Future of Rack and Stack

If you’ve ever walked into a data center, you’ve seen them, the unsung heroes of IT infrastructure. Rack and stack professionals are the backbone of modern computing, ensuring servers, switches, and storage units are installed correctly, efficiently, and securely. But how did this role evolve? What’s the job market like today? And most importantly, will AI and automation replace rack and stack technicians?
In this blog we will dive deep and explore:
✅ The history of rack and stack (from mainframes to cloud)
✅ The current demand (job growth, salaries, and key skills)
✅ The future outlook (automation vs. human expertise)
✅ Why this career isn’t going anywhere

The Past: How Rack and Stack Evolved
The Mainframe Era (1960s–1980s)

Before racks, there were mainframes, massive computers that filled entire rooms. Technicians manually wired and maintained these beasts.
Fun Fact: IBM’s System/360 (1964) required specialized raised flooring for cooling, an early form of data center design. (IBM Archives)

The Rise of Rack-Mounted Servers (1990s–2000s)

needed experts to:
✔ Install servers in standardized 19-inch racks
✔ Manage cabling and power distribution
✔ Optimize airflow to prevent overheating
By 2002, over 70% of enterprise IT used rack-mounted systems. (Gartner)

The Data Center Boom (2010s–Present)
Cloud computing exploded, and so did data centers. Hyperscale facilities (like AWS, Google Cloud, and Microsoft Azure) needed thousands of racks deployed quickly.

🔹 In 2023, there were over 8,000 data centers worldwide. (Statista)

The Present: Demand for Rack and Stack Professionals
Job Growth & Salaries
Rack and stack roles fall under Data Center Technicians or IT Hardware Engineers. The demand is strong:

✔ Projected job growth (2022–2032): 5% (faster than average) (U.S. Bureau of Labor Statistics)
✔ Average salary: $55,000–$75,000/year (higher in tech hubs like Silicon Valley) (Payscale)
✔ Top employers: Amazon, Microsoft, Equinix, Digital Realty
Key Skills Needed in 2025
Today’s rack and stack pros need more than just physical labor. Employers look for:
🔹 Hardware Knowledge (servers, switches, PDUs)
🔹 Cable Management (fiber, copper, power distribution)
🔹 Basic Networking (IP addressing, VLANs)

🔹 Safety Compliance (OSHA, NFPA standards)
🔹 Documentation Skills (using DCIM tools like Sunbird or Nlyte)
🔹 Certifications Help: CompTIA Server+, Cisco CCNA, AWS Data Center Technician, BISCI, OSHA 10/30

The Future: Will Automation Replace Rack and Stack Jobs?
The Rise of AI and Robotics

Some fear automation will eliminate these roles. While AI-assisted racking exists (like Google’s automated data center robots), humans are still essential for:
✔ Complex troubleshooting (AI can’t fix a bent server rail)
✔ Custom configurations (not every deployment is standard)
✔ Safety checks (preventing electrical hazards)
The Need for Hybrid Skills
Future professionals will need:
🔹 Basic scripting (Python, PowerShell for automation)
🔹 Cloud integration knowledge (AWS, Azure hardware setups)
🔹 Sustainability practices (liquid cooling, energy efficiency)
🔹 By 2030, green data centers will require 40% more skilled techs to manage eco-friendly hardware. (Uptime Institute)

Why This Career Isn’t Going Away

Cloud Growth = More Data Centers
🔹 AWS, Azure, and Google Cloud are opening new data centers every year.
🔹 Edge computing (IoT, 5G) means more localized racks.
Humans Outperform Robots in Critical Tasks
✔ Problem-solving when hardware fails
✔ Adapting to non-standard setups
✔ Ensuring compliance with safety regulations
High Turnover Creates Opportunities
Many techs move up to network engineers or data center managers, leaving entry-level openings.

Should You Become a Rack and Stack Pro?

If you:
✔ Enjoy hands-on IT work
✔ Want a stable, well-paying job without a 4-year degree
✔ Like problem-solving in fast-paced environments
No, if you:
✖ Prefer purely remote work (this job is on-site)
✖ Hate physical labor (lifting 50+ lb servers is common)

The Bottom Line
Rack and stack professionals are more relevant than ever. With cloud computing growing and AI still needing human oversight, this career offers job security, good pay, and a path to advancement.
