Dennis, Besides reading the book that John pointed you too, I'd suggest a mod-9 is NOT overkill. Just out Root, and Java filesystems together on 1.6 are 50,612 tracks. Regarding SYSRES, we just use a single mod-27 to house all targets, and SMPE controlled HFS(non-SMS managed) datasets, and a mod-27 to house all DLIBS, + SMPPTS's, etc. Both are running about 80% utilization. We then clone the target sysres to additional mod-27's to use as the actual running sysres volumes. Works good for us.
