IBM 42R5261 – PCI-X EXP24 Ctl-1.5GB No IOP

Detailed Description:

The IBM 42R5261 refers to a specialized PCI-X expansion controller designed for enterprise-level storage solutions. It functions as a core component in expanding server capabilities, particularly in managing and interfacing with external storage enclosures. The expansion controller operates with a bandwidth of 1.5GB, ensuring high-speed data transfer between the server and storage units. Despite its capability to support extensive storage expansion, this controller model does not include an Integrated Operating Processor (IOP), which means it relies on the server’s central processing unit for data management and operations. This design choice can lead to a more streamlined integration with the server’s existing architecture, making it a suitable choice for businesses looking to enhance their storage capabilities without significant modifications to their existing server setup. Its compatibility with the PCI-X standard also ensures it can be utilized in a broad range of server models, providing flexibility in deployment.
