Product Description
The IBM 69Y1936 is a specialized module designed for the IBM Flex System, functioning as a Fibre Channel Pass-Thru. Unlike a traditional switch, this module does not perform any switching operations; instead, it directly connects the Fibre Channel ports of servers within the Flex System chassis to external Storage Area Network (SAN) infrastructure. This direct connection simplifies the SAN topology and ensures that all traffic from the server ports is passed directly to the upstream SAN fabric. This pass-thru module typically offers a set number of ports, often configured as upstream and downstream connections. For instance, it might provide eight downstream ports to connect to the blade servers' integrated Fibre Channel adapters and eight upstream ports to connect to external Fibre Channel switches or directors. The 8Gb/s speed capability ensures compatibility with common SAN infrastructure speeds, providing adequate bandwidth for storage traffic. The primary benefit of using a pass-thru module like the 69Y1936 is its simplicity and the elimination of potential points of failure or bottlenecks associated with a switch. It is ideal for environments where the SAN switching logic is handled by external, more robust SAN switches, and the goal is to provide straightforward connectivity for blade servers. Its integration into the Flex System chassis allows for a consolidated and efficient deployment of compute and storage networking resources.
