Dy 4 Systems, a division of Force Computers, has introduced a Fibre Channel PMC module that is user-configurable to operate in two-channel (dual independent) or single-channel (dual redundant) mode.
Known as the PMC-643, it 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.
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, the PMC-643 doubles the data transfer rate of many existing PMC modules to 400MBytes/sec. by incorporating the Qlogic ISP2312 intelligent FC controller. Total throughput is 2Gbits/sec. via the front panel or 1Gbit/sec. through the backplane on rugged conduction-cooled models. In addition, the new PMC-643 maximises true high-speed communications capacity by connecting to the host basecard through a 64-bit, 66MHz PCI bus.
The PMC-643 is supported by Dy 4’s PowerPC 7410 processor-based single board computer, the SVME/DMV-181 and builds on the 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.
PMC-643 modules will be available July 2002. Pricing starts at $3,875.
