We are using two 386 mashines under Interactive Unix Version 2.0.2. Is it possible to use NFS not via ETHERNET but via the Adaptec - SCSI Host-Adapter ? If someone is using a big SCSI-Hardisk via NFS under Interactive Unix, can you please mail me how fast your configuration is ? ---- Thomas Humburg Universitaet Oldenburg thumburg@uniol

It is possible for this to work, although I don't know how feasible it is. The 1540A/1542A host adapters can be targets as well as initiators, but there is a limitation in the current SCSI protocol chip (AIC-6250) that only allows the host adapter to do one or the other one at a time. In other words if the board is selected by another initiator, no other commands for targets can be processed by the board. In the next rev of the board (I suspect 1540B), this will be cured and the adapter can go in any direction without any restrictions. I would think that a better solution would be to use, the Nodem for the ethernet link. (Nodem is a SCSI to Ethernet box). Although no UNIX drivers exist for this today. With the relatively low data rate of the ethernet link, the host adapter could blaze along and without degrading the CPU in the process. Someday......
