Case Study: AF Switchgear achieves uninterrupted power monitoring and protected billing data with Stratus Technologies' everRun Enterprise

Leading UK Switchgear Manufacturer Keeps Customers’ Power Monitoring Systems Up And Running Using Stratus Everrun Enterprise

AF Switchgear Ltd is a leading UK switchgear manufacturer with a growing Control and Monitoring Systems (CMS) division that delivers high‑granularity power monitoring and billing solutions for data centres and multi‑tenant buildings. Their systems collect meter data every quarter hour and cache it in RAM before writing to an SQL database, creating a risk that a single physical server failure could permanently lose in‑flight billing and usage data—something basic failover could not reliably prevent.

To eliminate downtime and protect RAM‑cached data, AF Switchgear deployed Stratus everRun Enterprise to run paired virtual machines across two synchronized x86 servers so applications and I/O are mirrored and preserved if hardware fails. The solution installs quickly with no software changes, provides real‑time management and remote monitoring, and—after rigorous testing—has delivered continuous availability, preserved critical billing data and given customers greater confidence in accurate tenant charging.
