Key takeaways

  • First decide whether you need an on-premises server at all: email and file sharing often fit better in Microsoft 365, while ERP, databases, CCTV recording and local applications may need one.
  • Size the server for your workloads: CPU cores, RAM, storage capacity and speed, with RAID and redundant power supplies for reliability.
  • Budget for the full picture: Windows Server licensing, backup, a UPS, a suitable room or rack, and a warranty with fast onsite support.

Buying a server is a five-year decision. Too small and it slows the business; too large and you pay for capacity and licenses you never use. This guide walks through the questions we ask before recommending a server.

1. Do you need a server?

Email, file sharing and Office apps often work better in Microsoft 365 than on a local server. You may still need one for an ERP or accounting database, line-of-business applications, CCTV recording, Active Directory, or when internet reliability or data residency make the cloud less suitable.

2. Size it for your workloads

  • CPU: list the applications and virtual machines you will run; most small businesses need one modern processor with enough cores for their VMs.
  • RAM: often the first bottleneck; plan for your VMs plus growth, and leave free slots.
  • Storage: SSDs for databases and virtual machines, larger HDDs for archives; plan capacity for three to five years of growth.
  • Network: at least two network ports, and 10 Gbps if you move large files or run storage over the network.

3. Build in reliability

  • RAID 1 or RAID 10 so a single drive failure does not stop the business.
  • Redundant, hot-swappable power supplies.
  • Remote management (such as Dell iDRAC or HPE iLO) for monitoring and support.
  • A UPS sized to shut the server down safely during a power cut.

4. Tower or rack

Tower servers suit small offices with no rack and are quieter. Rack servers suit companies with a network rack or server room, and make expansion, cabling and cooling easier.

5. Do not forget the costs around the server

  • Windows Server licenses per core, plus client access licenses.
  • Backup software and storage, ideally with an immutable or offsite copy.
  • A cool, secure location; heat is a common cause of failures.
  • A warranty with next-business-day onsite support, or faster for critical systems.

Frequently asked questions

Tower or rack server for a small office?

A tower server suits a small office without a rack and is quieter. A rack server suits companies that already have a network rack or plan to grow, and makes cabling and cooling easier to manage.

Which RAID level should a small business use?

RAID 1 (mirroring) for two drives, or RAID 10 for performance and resilience with four or more drives. RAID protects against drive failure but is not a backup; you still need separate backups.

How long does a server last?

Most businesses plan on five years, aligned with the warranty. After that, support costs and failure risk rise.
