Has anyone noticed any significant I/O contention in a raid environment where all oracle files exist only on a single disk array? We have a RS/6000 with 5 disk in an array and 4 non-raid disks. the tools will be on the non-raid disk but ALL other oracle files (online/offline logs, Index, Data, Rollback) will be on the array. The Appl is a Peoplesoft payroll database (V7.0.15) and the possability of many full table scans is high.
As a Oracle Geek this idea bothers me but I dont know how much parrallel I/O will go to negate any possible head contention.
Is this a problem or am I just being paranoid? Anybody had problems?
