Did you know?

The IBM Flex System EN4091 10Gb Ethernet Pass-thru Module provides 14 internal and 14 external 10 Gb Ethernet ports, and it supports 1 Gb and 10 Gb Ethernet signaling for Converged Enhanced Ethernet (CEE), Fibre Channel over Ethernet (FCoE), and other Ethernet-based transport protocols.

IBM Flex System, a new category of computing and the next generation of Smarter Computing, offers intelligent workload deployment and management for maximum business agility. This chassis delivers high-speed performance complete with integrated servers, storage, and networking for multi-chassis management in data center compute environments. Furthermore, its flexible design can meet the needs of varying workloads with independently scalable IT resource pools for higher utilization and lower cost per workload. While increased security and resiliency protect vital information and promote maximum uptime, the integrated and easy-to-use management system reduces setup time and complexity, providing a quicker path to return on investment (ROI).

Features and specifications

- The IBM Flex System EN4091 10Gb Ethernet Pass-thru Module has the following features and specifications:
- Internal ports: Fourteen internal full-duplex Ethernet ports that can operate at 1 Gb or 10 Gb speeds.
- External ports: Fourteen ports for 1 Gb or 10 Gb Ethernet SFP+ transceivers (support for 1000BASE-SX, 1000BASE-LX, 1000BASE-T, 10GBASE-SR, or 10GBASE-LR) or SFP+ copper direct-attach cables (DAC). SFP+ modules and DAC cables are not included and must be purchased separately.
