Is there a way to configure all 4 ports of Quad Fast Etehernet Adapter on
Solaris 8 box (Sun E450)
to act as a single port with one ip address and 400 Mbit/s throughput?

Any help would be greatly appreciated.

Yes, but you need to purchase the SunTrunking software. It can bond
them together to give you a single port. How well it works depends on
the switch you are attached to (if you use a switch) and the traffic
itself.

You can also use the IPMultipathing stuff in Solaris 8, but it's not
quite the same thing.

Just my two cents worth here, if I may.

A Gigabit Ethernet interface is more efficient and more cost effective in the
long run. The Sun Trunking software is just that, software. A pure interface
works far better and more effectively. You will need a switch with a gigabit
interface but they are cheap these days.

yes, but you need to buy the trunking software. Otherwise, you could
also use IP MultiPathing which would allow you to send out through all 4
ports, but receive on just one.

Not only that, but even with Trunking, you don't get 4x100, you get 4 100's
that all respond to the same IP address. Not quite the same thing.

In other words, you're not going to be able to e.g. ftp a file at 400Mbit .
It will go at 100. However, you can do 4 separate simultaneous ftp sessions
at 100 . See?
