Failover Cluster & Redundancy

High-availability solutions to eliminate single points of failure and ensure business continuity

What We Deliver

Design, implementation, and maintenance of failover clusters for critical workloads.

High Availability (HA) Architecture

Design and deployment of Windows Server Failover Clustering (WSFC) for SQL Server, file servers, and virtual machines.

Software

Windows Server 2016+, Failover Cluster Manager, Hyper-V, SQL Server Always On.

Hardware

At least 2 physical or virtual servers, shared storage (SAN, iSCSI), redundant network paths.

Human Intervention

Microsoft-certified engineers design, configure, and test failover scenarios.

Automatic Failover and Recovery

Zero-downtime failover for critical services with real-time health monitoring.

Software

Cluster-aware applications, heartbeat monitoring, quorum configuration.

Hardware

Dedicated heartbeat network, redundant power supplies, dual NICs.

Human Intervention

Engineers validate failover triggers and ensure automatic recovery works as expected.

Shared Storage Configuration

Implementation of shared storage using SAN, iSCSI, or Azure shared disks.

Software

iSCSI Target, Storage Spaces Direct (S2D), Azure Shared Disks.

Hardware

SAN/NAS storage, 10GbE network, dedicated storage network.

Human Intervention

Storage specialists configure LUNs, zoning, and permissions for cluster access.

Failover Testing and Documentation

Regular testing and full documentation of cluster behavior during failures.

Software

PowerShell scripts for automated testing, monitoring tools for validation.

Hardware

Test environment mirroring production, isolated network.

Human Intervention

Engineers conduct controlled failover tests and document results for compliance.
