One chanel or two for Fibre Channel PMC
module
Dy 4 Systems has developed the first Fibre Channel PMC module that is user-configurable to operate in two-channel (dual independent) or single-channel (dual redundant) mode.
Dy 4 Systems has developed the first Fibre Channel PMC (PCI Mezzanine Card) module that is user-configurable to operate in two-channel (dual independent) or single-channel (dual redundant) mode The PMC-643 supports Class 2 and 3 Fibre Channel (FC) and also a broad suite of standards-based protocols that include SCSI, IP and VI (Virtual Interface)
VI is an ANSI standard providing a lightweight, low-latency protocol for data communications, which has strong industry support.
In two-channel mode, the PMC-643 offers two fully independent Fibre Channel connections and can support operation of SCSI and IP or SCSI and VI on each connection.
In single-channel mode, the PMC-643 employs a port bypass switch for failover protection and is capable of supporting concurrent operation of all three protocols.
Furthermore, retimers employed in the module minimise jitter to data signals by retiming the data to the local reference clock.
Designed for defence and aerospace applications where high system throughput, speed and reliability are needed, the PMC-643 doubles the data transfer rate of many existing PMC modules to 400Mbyte/s by incorporating the Qlogic ISP2312 intelligent FC controller.
Total throughput is 2Gbit/s via the front panel or 1Gbit/s through the backplane on rugged conduction-cooled models.
In addition, the PMC-643 maximises true high-speed communications capacity by connecting to the host basecard through a 64bit, 66MHz PCIbus - the fastest available.
The PMC-643 is supported by Dy 4's PowerPCT 7410 processor-based single board computer, the SVME/DMV-181, and builds on the state-of-the-art FC controller technology pioneered by Dy 4.
Available in air- and conduction-cooled models, the PMC-643 supports VxWorks and drivers are available for the SCSI, IP and VI protocols.
