Detailed Specifications
HP 641146-B21 - Fabric Extender Module for BladeSystem
Overview :
The HP 641146-B21 is a fabric extender module designed for use in HP BladeSystem c-Class enclosures, intended for engineers and networking professionals integrating server blades with a upstream switch fabric. It provides high-density internal downlinks from blade servers and high-speed external uplinks into a parent switching chassis, thereby extending the network fabric into the blade enclosure. This module fits in the server edge (blade enclosure) and connects to a parent Cisco Nexus series switch, making it suitable for data-center blade-environments rather than standard campus or branch wiring closets. Because it behaves as a remote line card to the parent switch, it simplifies management by leveraging the parent switch's control plane. As such it is typically deployed in mid-to-large scale enterprise or service-provider blade-infrastructure where consolidation and unified management are required.
Key Features :
16 server downlink ports auto-negotiating 1/10 Gb
Eight external 10 Gb uplinks for fabric interconnect
Support for copper twin-ax and optical SFP+ uplinks
Managed entirely through the parent Nexus switch fabric
Compatible with HP BladeSystem c-Class enclosures
