StrataXGS® 32 x 40 GbE OR 104 x 10 GbE SWITCH WITH QSFP
INTERFACE SYSTEM VERIFICATION KIT
Overview
The BCM956850K is a complete System Verification
Kit (SVK) supporting up to 32 40 GbE ports via
Quad Small Form-Factor Pluggable (QSFP) connectors and cabling. It can support up to a maximum
1.28 Tbps.
Highlights
• Main PCB with BCM56850
40 GbE/10 GbE switch with
direct attach to QSFP ports
• PowerPC8548 CPU subsystem
• Wind River® Systems VxWorks®embedded real-time operating
system (run-time license)
• Latest version of the Broadcom
API driver
• 32 40 GbE ports via QSFP
The ports can also be configured as shown in the
examples below:
• 104 10 GbE (using 26 QSFPs)
• 96 10 GbE + 8 40 GbE (using all 32 QSFPs)
• 80 10 GbE + 12 40 GbE (using all 32 QSFPs)
• 48 10 GbE + 12 40 GbE (using 24 QSFPs)
The SVK is based on the BCM56850 device, a highdensity 32 x 40 GbE port switch on a single chip,
and a member of the StrataXGS® product family.
The BCM56850 is a family of Ethernet switches
designed to address performance, capacity, and
service requirements for next-generation data
center and cloud computing environments, 10G
Ethernet Passive Optical Network (EPON) Access
Infrastructure, Mobile Core Network, and
Enterprise Core equipment.
The BCM956850K also includes a modular
PowerPC8548 CPU subsystem capable of running
advanced management software. The CPU
subsystem connects to the main PCB via an internal
XMC slot, supporting PCI Express®.
