749.0. "a LOT of CDs on a Cluster" by NNTPD::"zofka@mail.dec.com" (Milan ZOFKA) Thu Apr 17 1997 15:34

Hello,

I'm currently working on a NT cluster of 4100 (Wolfpack? V1.1?).

The customer need to put ONLINE, at least 30 CD readers...

Any idea which solution I may propose that support Alpha?

Thank you for helping me, the customer would appreciate a StorageWorks
solution, they also provide 100 GB data, a.s.o.

    A hard disk is the only currently supported device on a shared SCSI
    bus; i.e., tapes and CD's are not supported.  You should probably be
    looking at network CD servers.

749.2So, how can I "propose" 30 CD OnlineNNTPD::"zofka@mail.dec.com"Milan ZOFKAFri Apr 18 1997 08:4321
If it's impossible to provide 30 CD on the shared SCSI bus, I may put 15 CD on
each server

It mean that if one server disapear, one half of the CD's are still
available...

BUT: Is it possible to share the disks on the CLUSTER ALIAS name
         How can I map theses 2*15 letters... A software that group several
SCSI CD
         to one letter would be great, but ON ALPHA...

What is currently the best choice? any idea of one software supported on NT
Alpha
with clusters? (example: microtest own a solution of CD towers (Discport
product))

Thank you for your prompt reply

Milan

	I just saw that we now support the infoserver on NT.  That gives you
	the ability to have network-based CDs.  I don't have the details, but
	a little searching might turn something up.

    If you install PATHWORKS 32 on NT Server 4.0 you have the ability to
    connect to the Infoserver CD-ROM drives .... these in turn can be
    shared like any other drive on the NT server.  This eliminates the
    requirement for each client to have the LAD/LAST protocols to talk
    directly to the Infoserver.
    
    Nice feature for those who have the Infoserver in their shops.

    Another solution might be to add a couple 4GB disks to the shared storage,
    and then copy the contents of the CDROMs to directories on these disks
    (CDROM <= 600MB --> 11 CD's <= 6.6GB)
