Rackmount Server Sizing

1U servers like the Dell PowerEdge R650 or HPE ProLiant DL360 pack two processors into minimal rack space and suit web, application, and virtualization tiers. 2U platforms — the PowerEdge R750 and ProLiant DL380 families — add drive bays and PCIe slots, making them the default choice for storage-heavy workloads, GPU acceleration, and general-purpose consolidation. 4U chassis serve specialized GPU-dense or high-capacity storage roles.

All rack servers we ship include rail kits on request and can be configured with your choice of processors, memory, drives, and network adapters. Mixed-generation fleet? We stock previous-generation systems so replacement nodes match your existing cluster exactly.

Frequently Asked Questions

Do rack servers include rails?

Rail kits are available for every system we sell — tell us at order time and we will include the correct OEM or compatible rails for your rack.

What is the difference between 1U and 2U servers?

A 1U server occupies one rack unit (1.75") and prioritizes density; a 2U server doubles the height to fit more drive bays, PCIe expansion, and better cooling headroom for GPUs and high-TDP processors.

Can I get a previous-generation model to match my cluster?

Yes. We deliberately stock previous and end-of-sale generations (e.g. PowerEdge R740, ProLiant DL380 Gen10) so you can add matching nodes without a forklift upgrade.
