VITA
34-Next Generation VME
Switched
fabric interconnects are emerging as the next technological
wave for communications. From chip-to-chip to board-to-board
to chassis-to-chassis, they are poised to change the way busses
function. The parallel synchronous bus may be giving way to
a point-to-point interconnection system. The VITA standards
organization is preparing for riding the switched fabric interconnect
wave with the VITA 34 standard.

The
main advantage of switched fabric interconnects is speed, followed
by redundancy, high availability and scalability. To increase
total throughput of a parallel bus, it must either be sped up
or widened, both of which tend to put more limits on the number
of devices that can be effectively connected to the bus. -More-

PICMG
3.0 update
PICMG
3.0 will be the core of an entirely new family of specifications
optimized for switched fabrics. It was based on the need to
create a "fabric agnostic" architecture.
The PICMG
3.0 subcommittee had its latest meeting on December 19th.
The four-hour teleconference had a large contingent of members
participating. It was an important meeting for several reasons.
First, the form-factor working group, led by Joe Pavlat, presented
its decision on an 8U by 280mm board size. The subcommittee
approved the working group's recommendation. Second, fabric
connectors were presented. Much like VITA 34, Tyco and ERNI
presented the ZD connector, FCI and ITT Cannon the Metral
line, and 3M presented the HSHM connector.
The next
meeting is a teleconference the week before Bus & Board. At
that time the subcommittee will vote on the connector. The
next face-to-face meeting is at Bus & Board, the 3rd week
of January.
