As of October 22, 1994, the MUSIC/SP
and support group is
running MUSIC entirely from an IBM PS/2 Model 95
(Our model uses a 60 Mhz Pentium processor.)
There are 12 dial-in lines and TCP/IP connections that
connect us to our world-wide user community.
We converted from an IBM 9375 Model 60 mainframe.
The PS/2 has the
and 370 channel card in it to allow
us to run the same applications and the same operating systems
as we were running on the mainframe.
The first thing vistors to our office notice is just how small
the new machine is compared with the old one!
Even though it is so much smaller it is more than
twice as fast for our
We have seen up to three times the file transfer speed when we are
using FTP to transfer files from remote hosts.
The disks are faster, smaller and much less expensive
than the old
We took advantage of the RAID 5 option on the PS/2
which allows the system
to keep running even if a disk drive stops working.
It also allows us to remove
a bad disk and plug a new one in while
our applications continue to run.
From the financial perspective
the purchase cost of the machine is about the list price for
one year's maintenance of the mainframe. And the PS/2's price
includes maintenance for 3 years.
The electrical power is much less and we now afford to have an
uninterruptible power supply to ride us over short power
outages and line glitches.
backups are now done using a PC program going
to a tiny 4 GB tape cartridge.
We could continue to use mainframe-type tapes but the new one
holds much more, is much smaller and backs up the PC files too.
As you can imagine we are very pleased with our new machine!
