Figure 7. ExampleofaReplacementofa9375Model60
One example is a software vendor who develops applications that run in a
VSE/ESA environment.This customer replaced a 9375 Model 60 and 9335 DASD
with the IBM S/390 Integrated Server with internal disk storage utilizing RAID 5
technology. Multiple VSE/ESA operating systems were run as guests under
VM/ESA. The customer placed the IBM S/390 Integrated Server onto an Ethernet
environment attaching users via TCT/IP 3270 sessions.In addition, the customer
kept the existing 3262 printer and two 2440 tape drives and attached the devices
via the S/390 Parallel Channel adapter.
1.Planning
The planning session took about one and a half days.The first day was used
to determine what was needed to move to the new environment and resolve
connectivity issues.One half day was spent mapping their volumes to the
RAID DASD to best utilize their resources.
2.Installation
Day
1: Installed and configured IOSP, (P/390 licensed internal code and
device drivers/managers) and RAID 5 disk storage.
