ATTO CTFC-641E-000 64Gb Gen 7 FC to x8 PCIe 4.0 HBA | Fibre Channel

Keep storage paths fast and predictable with a single-channel 64 Gb Gen 7 Fibre Channel host bus adapter designed for modern server architectures. The x8 PCIe 4.0 interface gives the adapter the bandwidth headroom needed to feed high-performance SAN environments without creating a bottleneck at the host edge. This low-profile card is a strong fit for dense rack servers, where slot space, airflow, and serviceability all matter. It is built for Fibre Channel deployments that depend on consistent block storage access for virtualization, database workloads, and shared infrastructure tiers. In environments where storage latency directly affects application response, the adapter helps maintain a clean, dedicated path to the fabric. Compared with lower-speed adapters, 64 Gb Fibre Channel gives infrastructure teams more room to grow storage performance without reworking the server layer. That makes it a practical choice for organizations standardizing on high-throughput SAN connectivity and looking to protect prior investments in Fibre Channel infrastructure.
