Hello,

    Here are a few questions for you network gurus. I've got a DN3000
that's been running as a standalone node for ~2 years now. I know
very little about the Domain network, but am in a situation where I
need to learn real fast.

   A friend of mine has a DN3000, purchased to run Intelligent Light's
rendering software, and he's now nearly out of disk space. The
rendering requires a large amount of virtual memory, and with his disk
90% full, he runs out of virtual memory real fast. We decided to hook
both of our nodes together in order to add additional disk space, which
would hopefully satisfy the virtual memory requirements of his
rendering software. But we can't seem to get it to work.

    Both nodes are DN3000s, each with 4MB RAM and 72MB disks. One has a
floppy and one has a cart. tape. Both are running sr9.7.

    We bought two of the DQC outlet boxes, wired them together with
regular coax, plugged the DQC cables into the DQC outlets, started
up "spm" and "mbx_helper" on both nodes, then typed "ctnode -update" to
both nodes. The nodes found each other, and we were able to cd to each
node, copy files from one node to another, and do a remote login with
the "crp -on //node_name" command. But when we started up the rendering
software, his node still ran out of virtual memory, acting as if there were
no additional disk/RAM available to it. What are we doing wrong? How do
you tell a node that there are additional disk/RAM resources available
to it on another node? Or is that even possible. I've read about NCS, so I
would think that what we want to do is fairly straightforward, since we
just want to share network resources.

    Also, is it possible to remove the operating system from one of the
nodes, so that the 72MB disk could be mounted as one file system on the
other node?

    Finally, does anyone know of an inexpensive way to swap the 72MB
disk for a larger capacity disk? Both of the nodes have the OMTI
controllers and 72MB micropolis disk drives. Apollo wants $4,500 to upgrade
the 72MB to a 155MB. Apollo's prices seem way out of line, especially
when I can buy a 620MB CDC WREN V for my Mac II for $2,900. Maybe I could
use the Mac as a fileserver for the Apollo :-)

    Thanks in advance,
	--Brian

btw--My Apollo has never crashed in the over two years that I've
had it, with it running continuously. Was I ever in for a surprise when
I got the Mac II...
