I would appreciate a lot if I can get this solution along with CISCO Hardwares.
The managing team explains the application as a
loosely coupled application for this cluster. As you
better know, these kinds of applications, generally,
do not need an interconnection network like
InfiniBand, or QsNet, which have higher BW and Lower
latency, and also are much more expensive compared to
GbE. As a result, we are looking for a GbE technology
interconnection which would meet our needs and be less
expensive (no RDMA, no TOE, on-board NICs). However,
there is a proprietary technology, Myrinet, which
offers very reasonable prices, even considering that
we have to buy and use its own NICs, with better
performance, including RDMA, TOE, non-blocking, higher
bw, lower latency.
Therefore, we have three choices: GbE Cisco, GbE
Force10, and Myrinet Myricom. Keeping our application
in mind, you see that hardware cost has a significant
impact on choosing one of the above choices. Against
to my expectations, I found Catalyst6500-based
clusters so expensive. Having studied Cisco's
products, I myself think that they have basically been
designed for other environments like data centers,
commercial sectors of the Internet, etc, with routing
features and security concerns, as they support wide
range of module cards in order to provide customers
with better services in those areas and most probably
this is the reason why they cost relatively more. I
would really appreciate it if you could help us make a
wise decision by examining the enclosed designs.
Let us know if we have missed to consider other necessary equipment in our designs or
made a mistake in using unnecessary equipment. I hope
you will offer us better solutions.
