Promentum ATCA-7220 RadiSys Dual Octeon CN58xx Packet Processing Module

The Radisys ATCA-7220 is an AdvancedTCA packet processing blade that provides highest available Gigabit Ethernet density and throughput. It incorporates two industry leading Cavium Networks OCTEON™ Plus multi-core processors with a powerful architecture to be used for intense packet processing application with or without I/O. On-board 10 Gigabit and 1 Gigabit Ethernet switching, acting as a “Smart Front-End”, allows powerful and flexible data flow for sophisticated security processing and traffic handling. AdvancedTCA form factor makes it appropriate for use in Carrier Grade network elements such as Security, Media Gateways and high bandwidth RNC and other network elements in wireless and broadband infrastructure. The AdvancedTCA module is available fully integrated into the award winning RadiSys Promentum™ SYS-6010 10 Gigabit Application Ready Platform to enable faster time to market for TEMs/NEPs to develop their next generation network elements.

The ATCA-7220 is a single slot AdvancedTCA packet processing module/blade compliant with PICMG 3.1 Option 9 interface specification. The OCTEON CN58xx processors are independent Data Processing Blocks with independent memory associated with them. Each processor includes up to 16 GB of SDRAM through two VLP MiniRDIMMs. For faster table look up applications, 128MB RLDRAM is optionally supported. The processors can also be configured in a pipelined mode by setting up the data flow to pass through the 10GE switch with HiGig™ capability in a “cut-through” fashion. Powerful architecture with “Smart Front-end” for data flow flexibilty, reliability and performance. The ATCA-7220 includes a 10GE switch on board that acts as a "smart front-end" for the OCTEON processors. This allows independent resetting of the OCTEON processing complexes for fault isolation, off-loading and augmenting the OCTEON data path processing software, and provides flexible data flow options. A Broadcom BCM56800 family switch serves as the central “hub” for I/O ports, OCTEON processors, the Local management Processor (LMP), and a secondary Broadcom switch. The switches also connect to the backplane Fabric and Base interfaces. The LMP is a stand-alone PowerQUICC III (MPC8548) CPU with 1GB of memory and a local flash file system, running a Linux OS. Its primary task is to provide blade management and switch management software for the Gigabit Ethernet switches. It also can host data control path software, diagnostics, and application provisioning software.
