Prestera™-FX9110/FX9210
9-Port/12-Port Crossbar Switch Fabric
98FX9110/98FX9210
PRODUCT OVERVIEW
The Marvell¨ Presteraª-FX family of crossbar switch fabrics are scalable building blocks for the development
of high-performance chassis systems. The Prestera-FX9110 crossbar switch provides 9-ports and supports
108 full-duplex Gigabit Ethernet (GbE) ports; the Prestera-FX9210 crossbar switch is a 12-port fabric that
supports 144 full-duplex GbE ports at full-wire-speed. The Prestera-FX9110 and Prestera-FX9210 devices
take advantage of a cell-based architecture with variable cell sizes and output queue scheduling to support
full speed Prestera-EX and Prestera-MX devices while maintaining Quality of Service (QoS) throughout the
system.¨ Used in conjunction with the Prestera packet processors, Prestera-FX fabric adapters, and the
Alaska PHY transceivers, Prestera-FX crossbar switch fabrics offer advanced enterprise core features
such as redundancy, hot-swap capability and stability.

APPLICATIONS
As illustrated below in Figure 2, a high performance, non-blocking 144 GbE enterprise core chassis switching system can be
designed with twelve 12 GbE line cards. As many as 576 GbE ports may be supported in a fully conÞgured 12-blade chassis.
These solutions accelerate the proliferation of Gigabit switching in the enterprise environment. Up to multiple Prestera-FX9110/FX9210
crossbar switch fabrics can be conÞgured to work in parallel for increased system performance and/or availability. In an active/
standby conÞguration, shown in Figure 3, one fabric is active while the other is in standby mode, waiting to take over if the active
crossbar fails or is removed from the system.
