Ceph distributed storage: how your VPS data stays protected

By ColossusCloud's Team January 31, 2026

ColossusCloud storage infrastructure

VPS hosting runs on ColossusCloud, our proprietary platform refined over years of development. Ceph distributed storage forms the foundation, keeping data safe, accessible, and performant.

Selecting Ceph for reliability

Ceph operates as a distributed storage system spreading data across hundreds of drives on multiple physical servers. No single failure point can compromise your data.

Our production Ceph experience spans nearly a decade. Managing dozens of clusters taught us precise tuning for performance and reliability. That expertise translates directly into superior uptime and storage performance for your VPS hosting.

Enterprise-class hardware specifications

Storage hardware meets enterprise standards:

  • NVMe exclusively: Every drive uses NVMe technology, not SATA or SAS
  • Samsung enterprise/data center grade: Drives designed for continuous 24/7 operation
  • Scale: Hundreds of NVMe drives distributed across multiple physical servers per cluster

This hardware selection delivers fastest available storage speeds backed by drives engineered for sustained enterprise workloads.

Redundant high-bandwidth networking

Storage speed depends on network connectivity. Every hypervisor connects to Ceph storage via:

  • Dual 40 Gbps connections, or
  • Dual 100 Gbps connections

Dual connections provide redundancy and bandwidth simultaneously. Single connection failures trigger automatic failover. With 40-100 Gbps available, storage operations avoid network bottlenecks.

Failure handling

Hardware eventually fails. The system handles it automatically.

Drive failure response

Your data remains intact. Ceph maintains multiple copies across different drives and servers. Drive failures trigger immediate automatic rebuilding onto other drives without intervention.

Storage host failure response

Your data remains intact. Identical redundancy protecting against drive failures extends to entire server failures. VPS operation continues, data stays accessible.

Hypervisor failure response

Ceph storage shines here. VPS data resides on Ceph clusters, not hypervisor local storage, enabling fast live migration. Your VPS relocates to healthy hypervisors and restarts quickly with all data preserved.

Balanced I/O allocation

Shared storage creates potential “noisy neighbor” scenarios where heavy I/O from one customer impacts others. Per-VPS I/O limits prevent this.

Depending on VPS plan selection, I/O speeds range from 1 GB/s to 10 GB/s, ensuring:

  • Consistent, predictable storage performance for your VPS
  • Protection from other customers’ heavy workloads
  • Reasonable bounds on intensive I/O operations

Operational expertise

Ceph deployment preceded widespread adoption. Nearly a decade of production operation provided:

  • Dozens of managed clusters across infrastructure
  • Optimal tuning discovery for various workload types
  • Monitoring and alerting systems for proactive issue detection
  • Operational knowledge maintaining cluster health

This experience minimizes surprises, accelerates problem resolution, and improves VPS performance.

Protection summary

VPS data protection includes:

  • Ceph distributed storage spreading data across hundreds of drives
  • Samsung enterprise NVMe drives designed for data center workloads
  • Dual 40G/100G network connections for speed and redundancy
  • Automatic failover during drive, host, or hypervisor failures
  • Fair I/O limits preventing noisy neighbor issues
  • Nearly a decade of operational expertise

This infrastructure supports every ColossusCloud VPS. Data stays protected, performance stays consistent.
