IBM 45D8781 server / storage / networking hardware Server Hardware / Parts

The IBM 45D8781 is catalogued as a Glacier OSA, an Open Systems Adapter feature for IBM mainframe systems. OSA provides the machine’s Ethernet connectivity, installed in an I/O drawer and shared by the operating systems running on the processor complex. Different OSA Express generations support different link speeds and connector types and are only supported on certain machine generations, so the exact card matters. Give us the machine type and model and the feature you are replacing.

System z mainframes and the largest Power servers are still running production workloads in banking, insurance, government and manufacturing. IBM designed them to be serviced part by part, with hot pluggable power, cooling and I/O units held in redundant configurations so that a single failure is a scheduled repair rather than an outage. Sourcing the correct unit for the machine type in question is what keeps that model working.

Send us the machine type, or a photograph of the label on the part you are replacing, and we will confirm the match before anything ships. Tech-Star (UK-based, shipped worldwide) supplies IBM hardware for maintenance and expansion projects. Please contact our sales team for availability, condition and pricing.
