I have read all SAP guides to maximise dump and load throughout but I always end up with maximum sybase io of 250gb/hr.
I have used :
1. Shared memory increase for backupserver
2. Number of stripes (higher)
3. Block size
And tried all combinations . On a disk IO of 1500 gn/hr sybase overall throughput io of 250gb/hr is very lower side .
Can you please guide me how can I achieve over 500 gb/hr?
