II      z/OS Hardware Preparation

1. Review Checklist in Installation Manual and at 

service.sap.com/platforms 

for

supported z/OS server models.

2. Determine Hardware Configuration by completing the SAP  sizing
questionnaire for R/3.  Review the sizing deliverable document prepared by the 
IBM ISV TechLine Sizing Department in conjunction with your IBM Sales Team or
implementation partner. Memory estimates will be provided as well. The questionnaire
is available online at:
http://www.ibm.com/erp/sizing or by request from [email protected].

3. Minimum DASD requirements for new installation are:

                 A. Non-Production (65) + (n) 3390-3 volumes

                        (60) 3390-3 volumes for SAP data
                        (2)   3390-3 volumes for DB2 active logs
                        (1)   3390-3 volume for DB2 catalog, directory, BSDS
                        (2)   3390-3 volumes for DB2 DSNDB07
                        (n)   3390-3 volumes for z/OS datasets(LINKLIB, PROCLIB, etc.)
                
                        (5)   3390-3 volumes for each  z/VM LPAR (RES, Spool, Paging)

                 B. Each additional  Non-Production system (65) 3390-3 volumes

                 C. Production (13) + (n) 3390-3 volumes plus (x) volumes for SAP data

                         (6) 3390-3 volumes for DB2 active logs
                         (3) 3390-3 volumes for DB2 catalog, directory, BSDS
                         (4) - (15) 3390-3 volumes for DB2 DSNDB07
                         (x) 3390-3 volumes for SAP data (minimum 60 for installation)
                         (n) 3390-3 volumes for z/OS datasets

                         (5)   3390-3 volumes for each  z/VM LPAR (RES, Spool, Paging)
              
                   (plus additional volumes if DB2 logs are archived to DASD )
                   (PAV implementation is highly recommended)
