- We have a SUN 690 MP with six ethernet interfaces on it. We intend to
- grow this system to serve about 200 SUN clients. With our data
- requirements, we want to run no more than 16 clients per subnet. This
- is assuming that the NC400 board is as good as a cisco (big
- assumption). I am only assuming cisco because I like cisco, but am
- open to any good alternatives. We use both cisco and NSC boxes for
- routing between sites, and to manage communications between differnt
- types of networks.
-
- Here is our dilemma. We run diskles systems (all local disk is swap
- with tmpfs). We like the simplicity of administration this gives us.
- We may even consider beefing up to a SparcCenter 2000 by mid year, but
- this does not (yet) address the problem of shear ethernet bandwidth to
- 200 clients. I realize that even SUN itself has many clients per
- server. What is the best way to do it? If broadcasts are not passed
- by a router, then how do you boot through the cisco?
- If you open up the cisco to pass broadcasts, then doesn't every
- connected subnet see all broadcasts?
-
- Secondly, how do you provide maximum bandwidth to each client? What
- is the best interface between the server and the router? FDDI maybe?
-
- Thirdly, each of the subnets needs access to the Amdahl running UTS
- for our disk farm. Does the cisco do SNA like the NSC?
-
- Too many choices...
-
- Inquiring minds want to know how you did it, or how you would do it
- if you could do it all over again.
-
- I will summarize.
