The choice of server hardware determines the sustainability of the business IT infrastructure for years to come. Companies need a balance: excessive configuration leads to unreasonable expenses, while insufficient configuration limits operational capabilities and requires premature modernization.
Server requirements for companies of different sizes differ significantly: the tasks of a store with a dozen employees and a production enterprise with a staff of a hundred people are solved by fundamentally different configurations.
In the article we will tell you about the main parameters of choosing servers for small and medium-sized businesses, the specifics of different types of server systems and examples of configurations for specific business tasks. The article will help to understand how to choose the right server for the development of your business.
The main criteria for choosing a server
Performance: processor and memory
The processor is the main component that determines the performance of the server. When choosing it is worth considering:
- The number of cores and threads - for most small and medium-sized business tasks, 8-12 physical cores are sufficient
- Processor frequency - affects the speed of non-separable operations
- Processor architecture - Intel Xeon or AMD EPYC demonstrate different performance depending on the type of load
RAM capacity determines the number of applications that can run concurrently without performance degradation:
- Minimum for small business - 16-32 GB RAM
- Optimal for medium businesses - 64-128 GB RAM
- For virtualization and database workloads, 256GB RAM or more
Disk subsystem: balance speed and capacity
The disk subsystem affects server responsiveness and data access speed:
- SSD drives - provide maximum access speed, recommended for hosting operating systems and active databases
- SAS HDDs - optimal choice for storing large data sets with moderate access rates
- Hybrid configurations - allows you to balance speed and capacity on a limited budget
For a small business server it is recommended to split into fast (SSD) and volumetric (HDD) storage subsystems using RAID arrays.
Scalability and upgrades
When selecting a server, it is important to consider future growth opportunities:
- Number of expansion slots - allows for the addition of new components
- Maximum supported memory capacity - should be at least twice as large as the initial configuration
- Availability of available disk bays - provides the ability to expand storage capacity
Servers with modular architecture provide more flexible upgrade options.
Reliability and fault tolerance
For critical systems, it is important to ensure continuity of operations by:
- Power supply redundancy - protects against power failures
- RAID support - ensures data integrity when individual drives fail
- Monitoring system - allows you to be alerted to potential problems
Energy efficiency and TCO
When choosing a server, you should analyze not only the initial cost, but also the total cost of ownership (TCO):
- Acquisition costs - the initial investment in the hardware
- Maintenance costs - the cost of technical support and scheduled upgrades
- Operating costs - power and cooling costs
- Software costs - the cost of licenses and upgrades
Low heat dissipation servers reduce power and cooling costs throughout their lifecycle.
Types of servers and their applications
File servers
File servers are designed to centrally store and provide access to files on a corporate network. A typical configuration for small to medium-sized businesses includes:
- Processor: Intel Xeon E-2300 or entry-level AMD EPYC 7003 processor
- RAM: 32-64 GB
- Disk subsystem: RAID 5/6 based on SAS HDDs with SSD caching
- Network interfaces: 2-4 10GbE or 25GbE ports
Application Servers
Application servers handle business logic of corporate systems (ERP, CRM, EDMS). Optimal choice for SMB:
- Processor: Intel Xeon Silver/Gold or mid-range AMD EPYC 7003
- RAM: 128-256 GB
- Disk subsystem: SSD for database, HDD for storage
- Network interfaces: 10GbE or 25GbE with aggregation capability
Server equipment for small business in this segment can be represented by compact solutions of 1U-2U format, providing sufficient performance with moderate power consumption.
Web servers
Web servers serve corporate websites, online stores and web applications. For small businesses, they are sufficient:
- Processor: Intel Xeon E-2300 or AMD EPYC 3000
- RAM: 32-64 GB
- Disk subsystem: RAID 1 on SSDs
- Network interfaces: 2-4 10GbE ports
Database servers
Database servers are designed for storage and processing of structured information. They are optimal for medium-sized businesses with active use of DBMS:
- Processor: Intel Xeon Gold or AMD EPYC 7003 of high class
- RAM: 256-512 GB
- Disk subsystem: NVMe SSD in RAID 10
- Network interfaces: 10/25GbE
Virtual servers (VPS)
Virtual private servers are virtualized partitions of a physical server and are a cost-effective solution for various tasks of small and medium-sized businesses. Advantages of using VPS:
- Low cost of entry compared to physical servers
- Rapid deployment - getting a new server up and running in minutes
- Ability to quickly scale resources
- Pay only for the capacity used
VPS is ideal for:
- Hosting corporate websites
- Testing and development of applications
- Running separate business services (mail, CRM, accounting systems)
- Organizing virtual desktops for remote work

Server Selection Tips
The following tips will help you avoid common mistakes and understand how to select a server for your company that best meets your business requirements.
Assess current and future needs
Needs analysis should cover not only the current state, but also the prospects for the next 2-3 years:
- Number of users: consider the company's growth plans
- Range of tasks: list all applications with their system requirements
- Peak loads: take into account seasonal fluctuations in activity
- Data requirements: estimate the amount of information stored and the rate of growth
When planning resources, it is recommended to set aside a 30% to 50% reserve to account for load growth.
Consider compatibility with existing infrastructure
The new server should integrate effectively into your existing IT environment:
- Physical constraints: rack sizes, power supply capacity, cooling
- Network infrastructure: network bandwidth compliance
- Software: compatibility with the OS and applications in use
Consider technical support capabilities
The quality of service directly affects the sustainability of business processes:
- Warranty terms: investigate warranty terms and limitations
- Spare parts availability: check the availability of local parts warehouses
- Response time: determine the speed of response to problems
Under current conditions, technical support for foreign manufacturers in Russia may be difficult:
- Increased delivery time of spare parts
- Limitations in firmware and software updates
- Difficulties with warranty service
For critical systems it is recommended to give preference to Russian solutions or manufacturers with official representation in Russia.
Pay attention to the manufacturer's reputation
The choice of manufacturer determines not only the quality of equipment:
- History of presence on the market: preference for companies with a proven reputation
- User feedback: study the experience of other companies in your industry
- Local presence: offices and service centers in your region
Conclusion
Choosing server hardware for small and medium-sized businesses is a task with many nuances. Unlike large companies, small businesses can afford neither costly mistakes nor excess capacity.
The main principle is a realistic assessment of needs. The server should cope with current tasks and have a reasonable margin for growth, but without overpaying for unnecessary capacity. It is especially important for a small business to consider not only the acquisition cost, but also the lifecycle maintenance costs.
If you are in doubt about how to choose a server for your business's specific needs, contact the experts at ITPOD. Professional consultation will help you avoid common mistakes and choose the optimal solution that will serve you for many years without the need for premature modernization.
