ATTO ThunderLink FC-5642 – Product Overview
The ThunderLink FC-5642 links Thunderbolt-enabled hosts to enterprise Fibre Channel storage, delivering high I/O throughput for demanding media, backup and database environments. It combines Thunderbolt 5 bandwidth with 64Gb Fibre Channel flexibility to support real‑time and transactional workloads.
Compact and engineered for reliability, the adapter supports multipathing, adaptive load balancing and ATTO’s Advanced Data Streaming (ADS™) technology, providing predictable performance for editing, delivery and infrastructure tasks.
Performance
Dual Thunderbolt 5 USB‑C connectors provide 80Gb/s Thunderbolt bandwidth while the adapter exposes two 64Gb Fibre Channel ports to maximise throughput for high‑resolution video and data transfers.
Fibre Channel Flexibility
Auto‑negotiation across 64G, 32G and 16G, support for point‑to‑point and direct fabric/switch attach, and ANSI Fibre Channel standards (FC‑FS, FCP) enable integration into existing SAN environments.
Redundancy And Load Balancing
ATTO MultiPath Director™ and adaptive load balancing provide failover and traffic distribution for highly available connectivity and improved switch‑port utilisation.
Management And Diagnostics
ATTO360 Storage software supplies tuning profiles, monitoring, analytics and ATTOexpert AI™ troubleshooting to simplify installation and optimise performance for specific workflows.
Data Integrity And Streaming
Advanced Data Streaming (ADS™) Technology and carefully engineered board design reduce latency and transmission errors, helping to ensure consistent, reliable transfers for real‑time applications.
Compatibility
Backwards compatible with earlier USB‑C Thunderbolt hosts and devices and offering drivers for macOS, Windows and Linux, the adapter suits mixed operating‑system environments.
Physical And Power
The desktop form factor fits creative spaces and racks with ATTO FlexRack; the supplied power adapter accepts 100‑240VAC and provides a 12VDC output for stable operation.
Environmental And Compliance
Designed for studio and data centre conditions with defined operating and storage temperature/humidity ranges and a broad set of international compliance approvals.
Warranty And Ordering
Ships with a three‑year warranty. Model variants include TLFC-5642-D00 (US) and TLFC-5642-DE0 (UK/EMEA); long‑range SFP+ variants are available on request.
