MM-6466D Quad fibre channel VME board with dual RACE++ on P2 and up to 8GB SDRAM

The MM-6466D is a 6U VME board with four independent, bi-directional 2Gb fibre channel ports and dual RACE++ on P2. Other features include a PowerPC processor, Gigabit Ethernet, VME64 master/slave interface and complete connectivity between all devices. Configurations are available with 2GB, 4GB, or 8GB of on-board SDRAM buffer memory.

The MM-6466D’s four independent fiber channel ports can each operate concurrently and in any direction. Data can be rate buffered in the up to 8GB of on-board memory between the RACE++ switch fabric backplane and fibre channel interconnects.

Acting as an output buffer, this implementation provides the ability to acquire data over the dual RACE++ ports on P2, rate buffer the data in up to 8GB of SDRAM, and then transmit the data at an aggregate rate of up to 800 MB/s to fibre channel SAN’s or persistent storage (JBOD, RAID, etc.). The reverse is also possible, wherein data can be acquired from persistent and stored in the large on-board buffer memory for quick access by DSP compute nodes over the RACE++ backplane. With multiple on-board DMA engines to maximize total throughput, the architecture is specifically designed for applications involving signal processing and real time data acquisition.

The PowerPC processor has 128MB of local SDRAM, up to 32MB of contiguous direct-mapped Flash, and a hardware Flash write-protect switch for high security environments. Other features include a DUART RS-232 serial port, programmable watchdog timer, Real-Time clock and RTC alarm, COP/JTAG, and front panel LED status indicators.

The PowerPC is utilized for hosting device drivers, setting up DMA transfers, scheduling tasks and message passing. The device drivers and well defined API’s are truly integrated into the VxWorks BSP, providing the flexibility and determinism expected from an embedded RTOS while balancing ease of use that results in a near plug and play solution.

A complete MC/OE API with “DX” like calls is provided for seamless interoperability in systems utilizing products from Mercury Computer Systems^®.

Reliability is ensured by extensive testing procedures. These include running diagnostics that stress multiple patterns and operations while cycling over various temperature ranges during burn-in.
