product overview the marvell prestera a -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. switching solutions prestera -fx9110/fx9210 9-port/12-port crossbar switch fabric 98FX9110/98fx9210 features benefits high performance?288 gbps non-blocking, supports up to 144 non-blocking gbe ports output-queued, cell-based crossbar multiple crossbar systems provides increased switching capacity and redundancy in high-performance applications 72 serdes links (54 for prestera-fx9110 device; 72 for provides additional bandwidth needed for ecc (8b/10b) prestera-fx9210 device), each running at 2.0/2.5/3.125 gbps link integrity protection 12 hyperg.link fabric ports (9 for prestera-fx9110 device; provides selectable bandwidth for a variety of chassis 12 for prestera-fx9210 device), each composed of either four and stackable system configurations or six serdes forming 10 or 15 gbps effective bandwidth per port proven serdes technology higher density, more reliable, lower power chassis systems hot-swap support chassis line cards may be inserted and/or removed without system power-down fast transition to a redundant crossbar provides system failure self-recovery stand-by mode saves system power in redundant configurations congestion control resolves fabric congestion using in-band flow control messaging with per-port granularity de-multiplexed address/data 32-bit synchronous bus interfaces with a variety of cpus and management subsystems and 2 two-wire serial interfaces (twsi) figure 1. prestera-fx9110/prestera-fx9210 block diagram 2xtwsi switch block uc/mc forwarding tables misc port o port 1 port 11 mg 32-bit cpu bus clk rst skip_init dev_en parallel i/o serial leds 10/15 gbps 4/6 serdes 10/15 gbps 4/6 serdes 10/15 gbps 4/6 serdes
