Detailed Specifications
HPE 854194-B21 10Gb Ethernet Pass-Thru Module II for c-Class BladeSystem
Overview
The HPE 854194-B21 is a pass-thru network module for HPE BladeSystem c-Class enclosures. It provides 16 SFP / SFP+ ports and delivers direct, low-latency 10 Gb Ethernet connectivity from individual blades to the external network. This module does not perform switching; instead, it transparently passes traffic, making it ideal for applications requiring predictable throughput or where blade I/O segregation is needed. It's unmanaged, eliminating the overhead of layer-2 switching logic, and compatible with both 1 Gb and 10 Gb optics per port.
Key Features
16 × SFP / SFP+ 10 Gb ports for direct blade-to-network links
Transparent pass-thru design with no switching or buffering
Auto-negotiation on each port for 1 Gb or 10 Gb speeds
Low-latency connectivity suitable for high-performance or converged environments
Fits into c-Class BladeSystem interconnect bays, supporting blade server I/O fabrics
