What I conculded from the replies I got, is that it is not a good idea
to put a server on an IDE machine since the scsi is much more faster and
handels I/O much more better than IDE.
But there will be no decrease in the performace when I add my HD pack to
the Ultra 5(IDE machine) with the condition that I use a SCSI disk for
the root FS and swap space,and ignore the IDE controller altogether
,except for the CDROM which will not affect the performance. In
addetion to this Ultra 5 should be faster than an Ultra 1, especially if
the SCSI controller and disk pack are wide/ultra and the Ultra 1 is as a
non-wide (not an 'E' suffix
machine).
My Original message was:
We have an Ultra 1 machine working as our NIS+ server. It holds also
our home directories which is auto mounted to other SUN boxes working as
NIS+ clients to that Server. All services on our Ultra machine are
stopped. It is used only as an authentication machine for the NIS+
clients and holds the home directories.
We want to replace that machine with another Ultra5 machine ( IDE with
SCSI interface to plug our SCSI HD's pack to it) we are wondering what
would be the performance of the new machine? Is there going to be a
decrease with the I/O speed since the new machine is IDE technology ?
I am not good with the SUN Hardware so I would be so grateful if anybody
share his experience with me.
Thanks so much
My Best Regards to you all
