Which server do I actually need?

Set the cores, memory, drive bays, accelerators, rack height and depth your workload needs. This returns the Dell, HPE and Lenovo servers that meet it — checked against each model’s own manufacturer document, ranked by how little capacity you would be paying for and not using, and honest about which requirement any model fails.

Best fit first — the machine that meets the requirement with the least wasted headroom, not the biggest one on the list.

One requirement away

These fail on exactly one constraint. Often the constraint is the thing worth revisiting.

HPE ProLiant DL145 Gen11fails on Drive bays — 6 vs 8+
PowerEdge XR7620fails on Processor cores — 0 max vs 64+
PowerEdge XE9712fails on Installs on its own — needs an enclosure or rack-scale frame vs a machine you can rack on its own
PowerEdge R5715fails on Processor cores — 32 max vs 64+
PowerEdge T560fails on Rack height — not rack-mount vs 2U or less
HPE Compute XD690fails on Rack height — 10U vs 2U or less

Choosing a server, answered

How do I know which server I need?

Work from constraints, not from a brochure. The four that decide almost every build are processor cores, memory ceiling, drive bays and rack height — then depth if the rack is shallow, and accelerators if the workload needs them. Set those here and the tool returns every current Dell, HPE and Lenovo model that meets them, ranked by how little capacity you would be paying for and not using.

Why does it rank the smallest match first?

Because the biggest machine on a list is rarely the right answer. A model that meets a 64-core, 1 TB requirement exactly is usually cheaper to buy, cheaper to power and easier to license than one that doubles it. The ranking is by least wasted headroom across the dimensions you set, then by rack height. Every match is shown, so if you want the ceiling you can take it deliberately.

What if nothing matches?

The near-miss list shows the models that fail on exactly one constraint and names it. In practice the blocker is usually rack height or drive bays, and it is often worth revisiting — a 2U instead of a 1U, or NVMe instead of more spindles, unlocks the rest of the catalogue.

Where do the specifications come from?

Each model’s own manufacturer technical document — the same verified library behind our 108 data sheets and 229 comparison pages. Cores are the maximum the document lists per socket times the sockets it supports; the memory figure is the stated ceiling; bays are the largest backplane configuration. Where a document does not state something, the tool says “not stated” rather than guessing, and treats it as acceptable rather than failing the model.

Does it consider price?

No. There is no pricing anywhere in the tool, by design — server pricing moves with configuration, quantity and the day of the quarter, so a published figure would be wrong the moment it was written. Shortlist on capability here, then ask us to quote the shortlist.

Can it help with rack depth?

Yes, and it is the constraint people forget. Comms rooms and older cabinets are often 800 mm or shallower while modern 2U servers run past 770 mm before cable management. Set a maximum depth and models are filtered on the figure in their own document; where depth is not published the model is kept and flagged rather than silently excluded.
