A smart network switch is a "blade" server that supports special applications such as protocol sessions, remote mirrors, 
Network Security,tape
emulation, and internal network files and data sharing. From the 
architecture of the extra processing capability for each port and the 
high integration of the bandwidth between the blade servers to the 
relatively simple architecture of each server is equipped with a 
dedicated processor, memory and the input and output functions for 
communication between various ports, the smart network switch has many 
different architectures. 
Different businesses use different 
words to name their switches, there are "smart exchange", "application 
exchange", "organization exchange" and so on, which are used to make 
themselves outstanding in competition. Cisco's MDS 9000 series, for 
example, has blades that support Veritas volume managers and IBM SAN 
volume controllers (SVCs). These blades can coexist with other blades, 
including fiber channel ports and IP servers. The Brocade 7420 
multi-protocol router is another example of advanced smart switches, 
which was originally used to support protocol conversion (from 
minicomputer interface to fiber channel), SAN segmentation and routing, 
and IP based remote storage that uses the FCIP protocol. 
Other 
switches support special blades, these servers cover everything from 
Maxxan to Marranti. CNT and McData also announced their plans to support
special blades. Since the word "smart" can have many different 
understandings in the field of data network communication, we should 
first define the "smart switch" or "smart network managed switch". 
Before defining such a type of switch, we should start with a 
traditional switch product category to understand why there is a strong 
demand for such a product category on the market.
