Overview FalconStor StorGuard is a software-defined storage virtualization solution designed to deliver enterprise-grade availability, disaster recovery, continuous data protection, and data migration across heterogeneous disk arrays and multi-site or hybrid-cloud environments. It centralizes critical data services—such as synchronous/asynchronous replication, microsecond-granular journaling, application-consistent snapshots, and intelligent failover—into a single platform. Deployed in both active-active or stretched metro-region configurations, StorGuard stands between application servers and storage infrastructure to ensure high uptime even during hardware or site failure.

Features and Capabilities

• Storage Virtualization & High Availability: Acts as a zoning layer to combine multiple disk arrays into virtual LUN pools with clustering, mirrored servers, and zero-downtime failover options.
• Continuous Data Protection: Captures all write I/O with microsecond granularity for near-zero RPO recovery points via a continuous journal.
• Application‑Consistent Snapshots: Supports consistent snapshots for mission-critical applications (SQL, Oracle, Exchange, etc.) with agent or script-based quiescing; groups up to 255 volumes per snapshot.
• Flexible Replication: Enables synchronous replication for metro-clusters and asynchronous for longer distances, complete with compression, encryption, and cascaded site configurations.
• Disaster Recovery & Metro Failover: Provides intelligent site failover/failback with integration into VMware vSphere, Hyper‑V, and StorSight management; protects against ransomware via timeline GUI to select safe recovery points.
• I/O Clustering: Supports active-active I/O clusters within a datacenter delivering up to 1 million IOPS with built‑in load‑balancing and multipathing.
• MicroScan Optimization: Network-level deduplication during replication, reducing bandwidth usage for DR and migration.
• StorSight Central Console: Offers web-based dashboard management, analytics, predictive capacity planning, patching, license control, and REST APIs across distributed StorGuard/StorSafe instances.
• Heterogeneous Storage Support: Compatible with Fibre Channel, iSCSI, InfiniBand, and various vendor arrays as virtualized underlying storage.
• Backup & Recovery Integration: Works with enterprise backup software, supports tape virtualization (StorSafe VTL), and facilitates seamless integration for backup and archival workflows.
• Deployment Flexibility: Installable as virtual appliance or on commodity hardware, deployable across physical sites or cloud platforms.
