HPE ProLiant vs Dell PowerEdge vs Lenovo ThinkSystem: Which Server Brand Suits an SME?
For an SME, HPE ProLiant, Dell PowerEdge and Lenovo ThinkSystem are closer than their marketing suggests. All three use the same Intel Xeon and AMD EPYC processors, the same memory types and the same drive standards. Choose by what your IT support already knows, which management tool you prefer, and which configuration can be delivered when you need it. Brand alone rarely decides performance.
How do the three brands differ in practice?
| Area | HPE ProLiant | Dell PowerEdge | Lenovo ThinkSystem |
|---|---|---|---|
| Remote management | iLO | iDRAC | XClarity Controller |
| Rack model prefix | DL | R | SR |
| Tower model prefix | ML | T | ST |
| Current generation label | Gen11 and Gen12 | 16th and 17th generation | V3 and V4 |
| OEM Windows licence | HPE ROK | Dell ROK | Lenovo ROK |

How do you read the model names?
Model numbers look random until you know the pattern. This is the fastest way to tell an entry server from a large one.
| Brand | Example | How to read it |
|---|---|---|
| HPE | DL320 Gen11 | DL is rack. 300-series is mainstream. 20 is one processor, 60 and 80 are two processors in 1U and 2U. A trailing 5 (DL325, DL385) means AMD. |
| Dell | R360 | R is rack. First digit is the class (2 and 3 entry, 4 to 7 mainstream). Second digit is the generation (6 is 16th). Last digit 0 is Intel, 5 is AMD. |
| Lenovo | SR250 V3 | SR is rack, ST is tower. 250 is one-processor entry, 630 and 650 are two-processor 1U and 2U. 645 and 665 are the AMD versions. |
Which models suit a small office?
An office of 10 to 50 people running a domain controller, file shares and one or two applications usually needs a one-processor entry server, not a two-processor machine.
| Need | HPE | Dell | Lenovo |
|---|---|---|---|
| One-processor entry rack | DL20 Gen10 Plus, DL320 Gen11 | R250, R360 | SR250 V3 |
| Two-processor 1U for virtualisation | DL360 Gen11 | R660xs | SR630 V3 |
| Two-processor 2U with more drive bays | DL380 Gen10 Plus | R760xs | SR650 V3 |
| Tower for an office with no rack | On request | On request | ST650 V3 |
What should decide the choice?
- What your IT support knows. A technician who has used iDRAC for years fixes a Dell faster at 2am. This matters more than any spec line.
- Lead time. Servers are configured to order. Ask for delivery dates on two brands before committing.
- Warranty terms. Compare years, on-site response time and whether parts and labour are both covered. Terms vary by model and are stated on the quotation.
- What you already own. Mixing brands is fine, but spare drives, rails and OEM Windows licences do not move between them.
The best server brand for an SME is usually the one its support team can repair without reading the manual.
How should you size it?
Start from workloads, not from a model. List the applications, user count, storage needed in three years and whether you will run virtual machines. Each server page on our site carries a short sizing questionnaire for this. Then check licences with our Windows Server licensing guide, because core count changes the licence bill.
If the old server is being retired because of the January 2027 deadline, read Windows Server 2016 end of support first. If the job is only file sharing, compare server vs NAS before buying a server at all.

Frequently asked questions
Is one server brand more reliable than the others? There is no public data that settles this for current models. All three are enterprise-grade; support quality and correct sizing matter more.
Can I use a Dell Windows licence on an HPE server? No. ROK licences are locked to the brand they were sold for.
Rack or tower for a small office? Tower if there is no rack and noise matters. Rack if you already have a cabinet with a UPS and switch.
Why are server prices not shown? Each server is built to a configuration, so the price depends on processor, memory, drives and warranty.
