[comp.sys.dec] Need info on Tape backup, memory and X-terminals

jmoore@cidmac.ecn.purdue.edu (James D Moore) (06/28/90)

I have been asked to gather some information about the
following items. We are looking for both good or bad
comments and recommendations. 

We need to buy a backup system, memory and X-terminals
for a lab setup. The system will be used for X application
development and educational X11 classes under ULTRIX. Our
system configuration will be as follows : 

(1) DEC3100server with 16mb of memory.
(2) 3 DEC3100 Stations as clients with 8MB (one has an RZ33? disk).
(3) 2 RZ55 (332MB) disks
(4) A yet undetermined 600MB+ hard disk.
(5) TK50 (95MB) tape unit.
(6) A yet undetermined number of X terminals (see question below)

Questions I need answered :

(1) Tape Backup :
    What would you recommend for the above setup ? What are you
    using ? Which brands to/not_to buy? 

(2) What other vendors, beside DEC whose prices are too high, sell memory 
    for DEC3100? I want to bring them up from 8mb to 16mb. Price and phone
    number would be appreciated here.

(3) X-terminal :
    We are looking at the DEC VT1000 and some others. What kind of overhead
    do X11 terminal have on the system? What do you recommend? How does it
    affect the performance of the system?  How many units would you have on
    the above setup ? What are you using?

Any information on the above (especially phone numbers and addresses) would 
be appreciated. I would also like to hear any kind of comments on the above
setup. If there is anything else you think I need to consider please feel
free to comment on it.

Thanks.

My .signature was a little too long on my last posted note. So I
have included it here.

  I would consider an 8mm Exabyte-based unit.  Our's comes from AVIV, works
  fine, but it is QBUS rather than SCSI.

  Clearpoint is one possibility.  You can find their ads in most of the trade
  rags.  Prices change constantly.
