Tandem Capacity Model (TCM) Manual

About This Document
Tandem Capacity Model (TCM) is a host-based and workstation-based capacity management tool
that predicts the number of processors and logical disk volumes required for a well-tuned system,
and estimates the expected response time and transaction throughput for OLTP and batch
transactions. TCM works with MeasTCM. TCM uses data collected by Measure on HP NonStop
host systems and summarized by MeasTCM.
New TCM Features and Microsoft Excel 2010
Starting with SPR T6945H01^AAY, TCM supports Microsoft Excel 2010 in addition to Microsoft
Excel 2007 and 2003. This manual uses examples based on Microsoft Excel 2010, and is also
compatible with Microsoft Excel 2007 and 2003. (See Appendix C: “TCM Menus” (page 221) for
Excel 2003 examples.)
Enhancements
TCM and MeasTCM now includes these new features:
• Support of new CPU types released after SPR T6945H01^AAX.
• Support of SAS Disks released after SPR T6945H01^AAX.
• Support for P9500 array.

Considerations
• Some of the TCM custom ribbon menus do not work when used with Excel 2007 on Microsoft
Windows 7 or Windows Vista. This Excel 2007 defect has been fixed with Microsoft Service
Pack 3, but this service pack is not available for Windows 7 or Windows Vista.
• TCM based on Excel 2007 does not support the Quick Access toolbar. These functions can
be accessed with the customized Excel 2007 ribbons.
