- Three z/OS 1.7 LPARs in basic sysplex, classic PROD,DEVELOP,SANDBOX scenario.

two physical
ESCON CNC/CTC pair.
- GRS on the PROD has an average delay of 7-8%. On the DEVELOP goes beyond
15-20%
- PROD has 2 CPs assigned, weight 70. DEVELOP has 1 CP, weight 20
- z890-230, 26 MSUs

Looks a good starting point to me. Thanks very much!
