Our VPS hosting runs on ColossusCloud, our proprietary cloud platform that we’ve been developing and refining for years. At the heart of ColossusCloud is Ceph, a distributed storage system that keeps your data safe, accessible, and fast.
Why we chose Ceph
Ceph isn’t just another storage solution. It’s a distributed storage system that spreads your data across hundreds of drives on multiple physical servers. This means no single point of failure can take down your data.
We’ve been running Ceph in production for almost a decade. During that time, we’ve managed dozens of Ceph clusters and learned exactly how to tune them for performance and reliability. This experience translates directly into better uptime and faster storage for your VPS hosting.
Enterprise-grade hardware only
We don’t cut corners on storage hardware:
- NVMe drives only: Every drive in our Ceph clusters is NVMe, not SATA or SAS
- Samsung enterprise/data center grade: We use Samsung’s enterprise and data center class drives, built for 24/7 operation
- Hundreds of drives per cluster: Each cluster contains hundreds of NVMe drives distributed across many physical servers
This hardware selection means your VPS benefits from the fastest available storage technology, backed by drives designed for continuous enterprise workloads.
Redundant high-speed networking
Storage is only as fast as the network connecting it. Every hypervisor in our infrastructure connects to the Ceph storage network via:
- Dual 40 Gbps connections, or
- Dual 100 Gbps connections
This dual-connection design provides both redundancy and bandwidth. If one connection fails, the other takes over. And with 40-100 Gbps of bandwidth, storage operations never bottleneck on the network.
What happens when hardware fails
Hardware fails eventually. The question is what happens when it does.
If a drive fails
Nothing happens to your data. Ceph automatically maintains multiple copies of your data across different drives and servers. When a drive fails, Ceph immediately starts rebuilding that data on other drives, automatically, without any intervention required.
If a Ceph host fails
Nothing happens to your data. The same redundancy that protects against drive failures protects against entire server failures. Your VPS keeps running, your data stays accessible.
If a hypervisor fails
This is where Ceph really shines. Because your VPS data lives on the Ceph cluster (not on the hypervisor itself) we can perform fast live migration. Your VPS moves to a healthy hypervisor and comes back online quickly, with all your data intact.
Fair I/O limits for everyone
With shared storage, one customer’s heavy I/O usage could impact everyone else: the “noisy neighbor” problem. We prevent this by limiting I/O per virtual server.
Depending on your VPS plan, your I/O speed ranges from 1 GB/s to 10 GB/s. This ensures:
- Your VPS gets consistent, predictable storage performance
- Other customers’ workloads can’t slow down your VPS
- Heavy I/O operations stay within reasonable bounds
Nearly a decade of Ceph expertise
We didn’t just install Ceph and hope for the best. We’ve been running Ceph clusters in production since the early days of the technology. During that time, we’ve:
- Managed dozens of Ceph clusters across our infrastructure
- Learned optimal tuning for different workload types
- Developed monitoring and alerting for proactive issue detection
- Built operational expertise that keeps clusters healthy
This experience means fewer surprises, faster problem resolution, and better performance for your VPS hosting.
The bottom line
Your VPS data is protected by:
- Ceph distributed storage spreading data across hundreds of drives
- Samsung enterprise NVMe drives built for data center workloads
- Dual 40G/100G network connections for speed and redundancy
- Automatic failover when drives, hosts, or hypervisors fail
- Fair I/O limits preventing noisy neighbor problems
- Nearly a decade of operational expertise
This is the infrastructure behind every ColossusCloud VPS. Your data stays safe, your VPS stays fast.
