[comp.protocols.tcp-ip.ibmpc] PC-NFS VAX and 3-Com

pa2183@sdcc15.ucsd.edu (John Clark) (05/26/89)

	I am trying to get info and experiences in hooking up the
	following components.

		A PC network using 3-Com's 3-Plus and 3-Server-3
		network system.

		A micro-VAX 3600 system.

	I would like to have a seamless connection from the PC's to
	the vax, i.e. mount vax filesystems as PC drives. This would
	suggest using NFS. Is it possible to get PC-NFS, VAX, and
	the 3-Com stuff to all play in the same band. Or must I junk
	the 3-Com server and put NFS everywhere?

	Thanks John Clark

	Disclamer: I didn't buy the 3-Com system I just inherited
	it.

asks about "seamles integration" between PCs on a 3+Share network 
and a VAX 3600.  I've been looking for a long time for a way
to do this between PCs and Suns, and NFS isn't any help.  NFS 
and NetBIOS have pretty incompatible views of what files are.

If you're using the right Ethernet boards in the PCs you can set
them up so they run 3+ and PC-NFS simultaneously.  But the 
memory requirements are pretty bad.  Or you can set the PC to boot
either on 3+ or PC-NFS.  Inconvenient, but we have a lot of users
doing this.  

You might do a little better by trying to make the VAX look like
a 3+ server.  I know of two products that claim to do this, 
although I have not seen them in operation.

Syntax Systems sells a product called SMBserver that lets your 
VAX act as a NetBIOS-compatible server, using either 3Com's 
variant of XNS or (I think) TCP/IP.  Phone was 206-833-2525
a year ago.

If you talk to your local 3Com sales rep, he can point you to a second
alternative.  3Com resells a Network Coprocessor board from
Virtual Microsystems.  Don't know about availability on a 3600. 

Good luck!
