PEX9700 Series Switch Chips

Managed PCI Express Switches Based on

ExpressFabric® Technology

Product Brief

Converge Servers and IO controllers with PCIe

• Create cost-eﬀective high-availability hyperscale systems by enabling

communication between in-rack hosts and endpoints using PCIe

• Simplify connectivity while providing the highest PCIe switching

performance available for data center servers, storage, and networks

• Reduce latency, system complexity, and power consumption

by up to 50% in data-intensive environments

• Take advantage of industry-ﬁrst features for most demanding hyper-

converged, NVMe and rack scale systems

Broadcom PEX9700 switches allow customers to build high performance, low

latency, scalable, cost-eﬀective PCI Express-based fabrics. The switches enable

I/O sharing with standard SR-IOV or multifunction capability, allowing multiple

hosts or Nodes to reside on a single PCIe-based network. Hosts communicate

through Tunneled Window Connection (TWC), a special low latency host-to-

host communication capability for short packets.

General Features

• State-of-the-art switch fabric

−Sharing I/Os among multiple

hosts

− Low latency TWC

• Any port can be a host port or

Downstream (device) Port

Shared I/O Using Standards

PEX9700 switches allow the Virtual Functions (VFs) of SRIOV endpoints

(such as an Broadcom MegaRAID® SAS controller) to be shared and

assigned to multiple hosts concurrently. Each host can enumerate its

assigned functions using standard BIOS and OS software and use them with

unmodiﬁed vendor-supplied drivers. The use of standard system software

minimizes software support costs.

• Works with standard PCIe end-

points and hosts – and software,

as well as with existing application

software

• MSI-X support

• Allows ﬂexible fabric topologies

Software-Deﬁned Fabric

The switches are built on a hybrid hardware/software platform that oﬀers high

conﬁgurability and ﬂexibility in regards to the number of hosts, end-points,

and PCIe slots. The critical pathways have direct hardware support, enabling

the fabric to oﬀer non-blocking, line speed performance with features such

as I/O sharing. The solution is completed by management processor that

communicates with platform management via API and/or CLI. The solution

oﬀers an innovative approach to setup and control, making use of an oﬀ-

chip management CPU (mCPU) to initialize the PEX9700 switch, conﬁgure

the routing tables, handle errors, Hot-Plug events, and enable the solution to

extend the capabilities without modifying the system software.

Key Advantages

• PCI Express Switches

−12 to 97 Lanes with Integrated

on-chip SerDes

−5 to 25 Independent ports

−Designate any Port as the

Upstream Port

− Low-power SerDes (under 90

mW per Lane)

Tunneled Window Connection (TWC)

TWC allows short messages to be sent from one host to another in a very low

latency manner, and without the overhead associated with DMA.

− Device-Speciﬁc Relaxed Ordering

− Port conﬁguration

− Dedicated management port

for mCPU
