Since this thread concerns 10 gigabit Ethernet, which switches can be
used to interconnect a small cluster of systems (<10) using the
PRO/10Gbe CX4 cards availbale on the 2950 III?

I saw a reference to a Dell power connect switch in a earlier thread,
but that switch doesn't seem to be available at the dell website. I
have not used 10 gigabit Ethernet before, but it seems to provide the
low latency that we are looking for.
