Great Lakes Racks and Enclosures to Secure and Scale Your IT Setup
Keep your IT equipment safe, organized and ready to scale with Great Lakes server racks and enclosures. At J.S. Fleming, we provide a wide range of Great Lakes solutions to help IT managers, network admins, and more get the right rack infrastructure to properly store critical equipment.
Is Your Server Rack Setup a Mess?
If your server rack setup feels more improvised than engineered, it’s a sign your IT has inherited or outgrown its current infrastructure. Many server rack environments simply weren’t built to scale:
- Servers and network gear with no standardized home
- Wasted or poorly used vertical space
- Tangled, unmanaged cabling running through every server rack mount
- Poor airflow that puts equipment at risk of overheating
- Unsecured server cabinets vulnerable to physical access
- Installations that take longer and cost more than they should
Critical infrastructure that your operations depend on shouldn’t be held together with improvised shelving and guesswork. Your organization deserves a server rack that was engineered for the job, not just an afterthought. That’s why J.S. Fleming is here to help.

Great Lakes Server Rack Equipment FAQs
What is a U?
1U equals 1.75 inches of vertical rack space.
What does "19-inch rack" mean?
It’s the standard equipment mounting width used across most server racks and server rack mounts.
What's the difference between a rack and a PDU?
A server rack or server cabinet houses your equipment. A PDU (power distribution unit) distributes power to it.
Does the rack include a PDU?
Generally, they’re sold as separate products — but pairing a PDU with your server rack is a natural add-on worth planning for.
Why Great Lakes?
A broad range of server rack and enclosure options, flexibility across applications, a full accessory ecosystem, and the backing of Vertiv’s broader critical infrastructure portfolio.
How do I know what size server rack I need?
Start with what’s going inside — the equipment type, quantity, and dimensions. From there we help you factor in U-space, depth, and weight capacity so the server cabinet you choose fits both your current equipment and near-term growth.
What's the difference between a server rack and a server rack mount?
“Server rack” typically refers to a full-size, floor-standing enclosure, while a server rack mount (like a wall mount) is a smaller unit designed to attach directly to a wall — a good fit when floor space is limited.
What's the difference between an open frame rack and an enclosed server cabinet?
An open frame rack (like the Frame Rack 2-Post) provides mounting rails without side panels or doors, offering easy access and airflow. An enclosed server cabinet adds doors, side panels, and often locking access for greater physical security and environmental control.
How much weight can a server rack hold?
It varies by model — anywhere from around 1,500 lbs. on a network-focused frame rack up to 4,500 lbs. on a high-capacity cabinet like the Rack Extreme. Weight capacity should factor in both the equipment itself and any accessories you plan to install.
Do I need a seismic-rated rack?
If your facility is in a seismic zone or your industry requires it (common in telecom, government, and certain data center environments), a seismic-rated server rack like the Rack Seismic helps protect equipment during ground movement.
