For a modern small business, a server is no longer “just a PC in the corner”. You need a reliable platform for file sharing, accounting, CRM, small databases, backups and light virtualisation. HPE ProLiant servers are designed exactly for that balance of reliability, scalability and reasonable cost.
If we get straight to the point, the best HPE servers for small businesses in 2025 are HPE ProLiant MicroServer Gen10 Plus, HPE ProLiant ML30 Gen11, HPE ProLiant ML110 Gen11, compact rack server HPE ProLiant DL20 Gen11 and the more powerful yet still SMB-friendly HPE ProLiant ML350 Gen11. Together they cover scenarios from a 10-person office to a growing company with dozens of users and multiple critical services.
In this guide, we will compare these models, explain which workloads they suit best, provide a quick comparison table and give practical tips on how to choose the right configuration for your use case: file server, light virtualisation, branch office, accounting workloads and more.
What small businesses really need from a server
Even with 10–30 employees it quickly becomes clear that a single powerful laptop or a random desktop is not enough. Typical requirements appear:
- centralised file storage with access control and auditability;
- fast and stable work of accounting or ERP systems with several concurrent users;
- internal services like CRM, intranet, ticketing or simple web applications;
- reliable backups of workstations and critical databases;
- light virtualisation — several virtual machines for separate services and test environments;
- secure remote access for employees working from home or branch offices.
HPE ProLiant Gen10, Gen10 Plus and Gen11 servers meet these needs with ECC memory, robust storage controllers, remote management via iLO and flexible drive configurations. At the same time many models remain compact and power-efficient enough to run in a small office without a dedicated server room.

How to choose the right HPE server for your small business
To make a good choice, start from your workloads and a realistic growth horizon of at least 2–3 years. Below are common scenarios and recommended models.
1. Very small office with up to 10–15 employees
Core needs: shared files, simple database or accounting system, local backups, maybe a small in-house application.
- Recommended: HPE ProLiant MicroServer Gen10 Plus or HPE ProLiant ML30 Gen11 in an entry configuration.
- Memory: 16–32 GB RAM to keep some headroom for future services.
- Storage: RAID1 for OS and data, plus a separate volume or external device for backups.
2. Classic small business with 20–50 users
Here you usually have an accounting/ERP system, SQL database, file server, perhaps an internal CRM and intranet, all serving dozens of users.
- Recommended: HPE ProLiant ML30 Gen11 or HPE ProLiant ML110 Gen11.
- Memory: 32–64 GB RAM for comfortable multi-service workloads and light virtualisation.
- Storage: RAID10 (4 disks) for databases and “hot” files, with a separate backup target.
3. Branch office or multiple locations
You run several sites, use VPNs, and place your server in a rack (on-prem or in colocation). The server hosts directory services, local apps and some VMs.
- Recommended: HPE ProLiant DL20 Gen11 as a compact rack server, or HPE ProLiant ML110 Gen11 / ML350 Gen11 where more headroom is required.
- Memory: 64 GB RAM and more if you plan to run several VMs.
- Storage: a mix of SSD for performance-critical workloads and HDD for archives and backups.
4. Fast-growing company and virtualisation-first strategy
If you expect your infrastructure to grow quickly and want to host many workloads on a small number of physical machines, planning for virtualisation from day one makes sense.
- Recommended: HPE ProLiant ML350 Gen11 with the option to add a second CPU and expand memory later.
- Memory: start with 64–128 GB RAM and plan to upgrade as you add more VMs.
- Storage: fast SSD pool for virtual machines and logs, capacity-oriented HDD pool for backups and cold data.
Key decision criteria
- Resource headroom: avoid sizing “to the last megabyte” — plan for growth in load and data volume.
- Resilience and backup: think in terms of RAID and independent backups, not one or the other.
- Remote management: iLO licences can significantly reduce on-site interventions and downtime.
- Form factor: tower servers are convenient for offices without racks; rack servers are better if you already have a dedicated server room or colocation.
