For a company providing web hosting, VPS, and VDS services, the most critical element is choosing the right server hardware. In this article, we list the most suitable devices for businesses looking to offer server hosting services, along with their technical specifications in detail. We also provide guidance on how to configure with virtualization solutions like ESXi and vCenter, and offer industry-specific recommendations.

Hardware Criteria Required for Server Hosting

Processor (CPU): Multi-core and high-frequency processors are critical for virtualization performance.
RAM: A minimum of 64 GB is recommended. 128-512 GB of RAM should be planned according to the number of VPS/VDS.
Disk: NVMe SSD should be preferred. A redundant and high-speed structure is established with RAID 10.
Network Port: At least 1 Gbps, preferably 2.5 Gbps or 10 Gbps connection is required.
IPMI/DRAC/iLO: IP KVM support should be available for remote management.

Things to Consider in Virtualization Architecture with ESXi & vCenter

Hardware Compatibility: ESXi HCL (Hardware Compatibility List) should be checked
RAID Structure: RAID 10 is ideal for performance and security
Network: 10G uplink + VLAN configuration is recommended
Datastore: SSD/NVMe Datastore + separate storage area for backup should be planned
vCenter: Mandatory for managing multiple ESXi nodes, HA, and DRS

Comparison of Proxmox, ESXi, and Other Platforms

Feature	ESXi	Proxmox	Hyper-V
License	Paid	Free	With Windows Server
Interface	Web + vSphere	Web GUI + CLI	GUI + PowerShell
Virtualization	Not KVM supported	KVM based	Hypervisor
Cluster	With vCenter	Built-in	Failover Cluster
Backup	Veeam, Nakivo	PBS integrated	External software required

Additional Notes and Tips

RAID cache and write limit should be considered on servers for SSD lifespan
Allocate a minimum of 2 vCPU, 4 GB RAM per VPS/VDS
Plan IPv4 subnet for IP address management, don't forget IPv6 support
"Hot swap" disk support should be preferred in hardware
It is recommended to establish a redundant structure (HA, vMotion) with vCenter

Conclusion: Choosing the right server is vital for hosting companies in terms of service continuity, customer satisfaction, and profit margin. This guide provides a strong start with 30 different hardware recommendations from entry-level to enterprise level. Carefully setting up ESXi, vCenter, and RAID structures during the configuration phase makes a big difference in terms of performance.
