Lenovo 42D0491-RF 8 Gb Fibre Channel HBA | SAN Adapter, Enterprise

Keep storage traffic on a dedicated Fibre Channel path with a single-port 8 Gb host bus adapter specified for enterprise SAN environments. The Lenovo DCG sourcing part number 42D0491-RF is positioned for teams that need dependable host-side connectivity and a clean fit into standardized infrastructure programs. An 8 Gb Fibre Channel adapter is a practical choice when you want consistent access to shared storage without overcomplicating the server design. It supports the kind of workload isolation and fabric discipline that matter in production virtualization, database hosting, and general-purpose SAN attachment. This model also carries procurement value. Certified sourcing helps reduce ambiguity during refresh cycles, while the 1-year IMS warranty standard adds a defined support window for deployment planning. For buyers comparing lower-cost alternatives, the difference is not just the port speed — it is the combination of enterprise fit, sourcing control, and warranty coverage that supports a more predictable lifecycle.
