Overview
Telegrupp AS, based in Tallinn, Estonia, delivers high availability IT infrastructure and managed services to clients across Northern Europe. The company specializes in building resilient systems and has earned a strong reputation for reliable technology solutions.
To improve uptime and accelerate recovery in its own infrastructure, the team at Telegrupp implemented StorMagic SvSAN. The results were immediate. The company reduced recovery time by 50% and significantly improved system performance.
The Challenge
Before switching to StorMagic SvSAN, Telegrupp faced three core challenges:
- Frequent downtime interrupted operations
- Disaster recovery processes took too long
- Provisioning new virtual machines created operational delays
The existing VMware vSphere-based storage setup could no longer support the company’s evolving performance and reliability needs.
The Solution
Telegrupp selected StorMagic SvSAN to modernize its infrastructure. After years of recommending the product to customers, the team already trusted its stability and ease of use. They installed SvSAN in a small, high-performance datacenter environment with the following configuration:
- Hyperconverged cluster with Lenovo servers using 24-core CPUs
- 10 NVMe drives per server in RAID-1, handled by the Lenovo ThinkSystem RAID Enablement Kit, with 93 TB of usable storage
- Core services running on SvSAN include:
- SQL Server
- Exchange Server
- Web hosting
- Kubernetes cluster
- Network management solutions
- AD and DNS controllers
Telegrupp runs these services on VMware vSphere and manages the environment through CLI, WebGUI, and the vCenter plugin. The team also protects data using Veeam backups and encrypted storage, with offsite backups.
The Results
After deploying SvSAN, Telegrupp achieved:
- 50% faster performance across all core business applications
- 50% reduction in HA failover time
- Faster provisioning of virtual machines
The infrastructure now supports critical business functions without interruption. Application responsiveness improved, and disaster recovery became more efficient and predictable.
“I like how it works. It’s quick, easy to understand, and it definitely made our business process more efficient.”
Daniil Lemberg, Infrastructure Lead at Telegrupp AS.
Why StorMagic?
- Telegrupp had witnessed SvSAN’s strong track record having recommended the software to clients and seeing it perform reliably
- A better technical fit compared to alternative solutions
- A lower total cost of ownership
These factors aligned perfectly with the company’s need for high availability and operational simplicity.
By using the same technology it recommends to customers, Telegrupp builds greater trust and credibility. The team speaks from experience and demonstrates the value of SvSAN in real-world environments.
“We trusted the product after seeing how well it worked for our clients. Using it internally proved its value again.”
Daniil Lemberg, Infrastructure Lead at Telegrupp AS.
