DSA 7.13: VP question

Hi, 1. A client of us is upgrading his system with some extra disks. The problem is that 50% of the disks (2 out of 4) are only used to hold historical data that is almost not queried, and certainly not updated. How many AIO VP's should I define, 1 for every (physical) disk or only 1 for every (physical) disk that does not contain historical data. 2. An other problem we have is that the system sometimes seems to lock itself up. The system is for example 40% idle and if another proces is started it changes to 0% idle. The server is an HP9000-K210 1 proc. and Informix DSA 7.13. This machine is the application and database server. My guess is that with the multi-threading architecture the defined CPU VP (only 1 defined like mentioned in the manuals)gets less time to do more work if a lot of user-programs are running. Is it wise to define more than 1 CPU VP. The workload consists of a mix of interactive and batch programs.
