- We have 26 SPARCstations, all of which use disks on a HSC50 in a
- VAXcluster that has a VAX 8550 and 8530. Currently the 8550 has
- the Multinet software and everybody is on the same Ethernet segment.
-
- Traffic is high and I think splitting into two or more subnets and
- physically different segments would help. Would the following work?
-
- I would add Multinet to the 8530 and split the single segment into
- two sections, breaking them on workgroup boundaries. Each VAX would
- be on a different segment and be an NFS server of (even the same) HSC50
- disk drives to each segment. However, we do want some limited IP traffic
- (ping, telnet, rlogin, ftp, snmp) between the segments. Could I then
- essentially use the VAXCluster as a router by running IP over
- DECnet over the CI interfaces (remember the Ethernet controller
- on one VAX is not on the same segment as the Ethernet controller
- on the other VAX) and use the routing support in Multinet?
- Or can Multinet use the CI interfaces directly?
-
- We do have some VAXstations and they will lose their failover
- capability between the two 8500s as boot and server nodes. Is there
- anything else I might be overlooking or another configuration to consider?
-
- Could I also add second Ethernet controllers to the 8500s to get
- 4 segments? (I am assuming I would get better NFS performance by
- having two CPUs involved than one as I do now.)
