10 gigabit Ethernet - Add on question

[Scott_Purcell at Dell.com]

The PowerConnect 62xx series of switches are predominantly layer 2/3
Gigabit switches but they have up to four 10 Gig ports.

There may be other offerings we have, but that's the only one I found.
You can find it on the website by choosing "Servers, Storage &
Networking > Large Business > Networking > Managed Switches > Managed
Layer 3 Gigabit Ethernet"

Hope that helps.

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.

thanks
