3747.0. "HW configuration for a small backup server" by VAXRIO::16.179.32.22::VAXRIO::ALCIDES (Storage Sales) Tue May 13 1997 16:10

I have a customer who needs a small backup server for his environment. I'm 
proposing an Alphastation running NT.

Their environment is: 9 HP-UX, 1 AIX, 1 Solaris, 5 NT Server Intel, 5 Netware 
Server. 140 Gbytes of total storage. They have a standard ethernet (10Base-T) 
network.

My proposal is:

Alphastation 255/300 running Windows NT
128 Mbytes of memory
2 RZ28 disks (one for NT, other for NSR)
1 KZPAA dedicated to a TZ885
TZ885 operating in compressed mode

The customer needs the solution as cheap as possible. I'm not sure that my 
assumptions in the HW configuration are correct. 128 Mbytes of memory is too 
much? A dedicated KZPAA is really needed?

And answered there too.  Note 672.4.  (The gist is, the 10BaseT 
isn't very fast, but it should be ok for this environment)
3747.2Controllers and cables ...VAXRIO::16.179.32.22::VAXRIO::ALCIDESStorage SalesTue May 13 1997 22:488
Yes, the network is the bottleneck.

I have other questions:

1) Which SCSI controllers can I use with a TZ885-NT (table-top)? KZPSA-BB 
(FWD)? KZPDA-AA (FWSE)? KZPAA-AA (FNSE)?

2) What cables should I use in each case?
