Case Studies

Real examples of how we help businesses solve IT problems, from day-to-day support and cloud migration to security and server infrastructure. Each case shows the situation, what we did and the result.

RAID in practice: expanding an array from 8 to 24 TB and replacing a failed drive with zero data loss

Problem: A large accounting and audit firm was running out of server space, and for another client one of the two drives in its RAID arrays started to fail.

Result: We expanded the array from 8 to 24 TB with a RAID1 to RAID5 migration in 1-2 working days and replaced the other client's failed drive. In both cases the server was online 99% of the time with zero data loss.

From Infrastructure Chaos to Security Control: How We Automated Patch Management Across a Large Server Environment

Problem: Infrastructure kept growing faster than the maintenance routine — there was always a server that hadn't been updated in months, because manual patching across dozens of machines couldn't keep up.

Result: We built centralized automated enrollment, monitoring and update visibility — a new system no longer means a new manual chore.

Building Reliable Network Infrastructure for a Distributed Logistics Operation

Problem: The client's warehouses sat in industrial areas with only one available ISP — a single outage could isolate a site completely.

Result: We built automatic failover between the primary line and 4G with centralized monitoring — an ISP outage no longer becomes a business outage.

Making Remote Modbus Connectivity Reliable and Transparent

Problem: A direct VPN connection to remote PLCs looked like a clean network design, but connections kept dropping and Modbus communication was unreliable.

Result: We built a transparent tunnel through the existing edge routers with automatic recovery — stable industrial communication with no changes to the applications.
