Hi friends,

Our database is on HCL machine with RAID 5 technology.
Sometimes I get datafile random read average time more than 30 ms when I monitored database using spotlight tool.
It was mentioned that datafile random read average time should have less than 30 ms.
Generally this happens when no. of database users increases.
Is hard disk is slow?
Please guide me.
