Detailed Specifications
HP 571956-B21 - Virtual Connect FlexFabric 10Gb/24-Port Module
Overview :
The HP 571956-B21 is a blade interconnect module designed for server-blade environments, aimed at IT and infrastructure engineers needing to converge LAN and SAN traffic within a blade enclosure. It supports multiple 10 Gb ports and converged networking protocols like Fibre Channel over Ethernet (FCoE) or accelerated iSCSI to reduce cabling and switch count. This module sits in the interconnect bays of a BladeSystem c-Class enclosure, making it suitable for datacenter or campus blade deployments. It integrates with the HP Onboard Administrator and Virtual Connect management layer, enabling configuration of uplinks, downlinks and virtualised network functions in a managed blade-infrastructure context.
Key Features :
24 downlink ports at 10 Gb for blade network connections
Four SFP+ external uplinks configurable for 10 Gb Ethernet or 2/4/8 Gb Fibre Channel
Full-duplex switching fabric rated up to 240 Gbps non-blocking throughput
Supports MTU up to 9,216 Bytes for jumbo-frame traffic
Internal cross-connect links allow module stacking and redundancy
