Detailed Specifications

HPE 657787‑B21 B22HP Fabric Extender 

Overview

The HPE 657787‑B21 is a fabric‑extender module designed for blade‑server enclosures, offering 16 internal down‑links to server blades and 8 external uplink ports to a parent switch fabric. It enables network consolidation at the server‑edge by logically extending the parent switch’s fabric into the enclosure, simplifying management and reducing edge switch count. Typically deployed in high‑density blade‑server racks, the unit supports Ethernet, FCoE and data‑centre bridging protocols, fitting into modular rack‑mount infrastructures. The module is compatible with certain blade‑server chassis and integrates with existing management frameworks for unified operation of blade I/O and network fabrics.

Key Features

  • 16 internal down‑links to server blades

  • 8 external uplink ports (10 Gb SFP+ form‑factor)

  • Logical extension of parent switch fabric into blade enclosure

  • Supports Ethernet, FCoE and data‑centre bridging (DCB) features

  • Enables reduction of separate access‑switch layers at server‑edge
