- With all the discussion about the HP-UX cluster and performance, I have to
- ask this question: does everybody who gets good cluster performance have
- a second LAN to support the client nodes?
-
- We had a cluster of 2 425e machines (each fully loaded with RAM, and at least
- 200Mb local swap each) with a 433s as the server (80Mb RAM). However, running
- a second Ethernet wasn't an option, so the DUX protocol was sharing the
- wire with all the other traffic (TCP/IP, AppleTalk, DECNET, LAT)...
-
- Performance on both the cluster server and clients seemed low; we converted
- one of the clients to a standalone, and performance improved quite a bit.
- [The machines are still overloaded, but now it's more tolerable...].
-
- Are there any hard numbers on how much traffic the DUX protocol generates,
- and how much other traffic it can tolerate and still give good performance?
