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
