HELLO we have 2 exchange server running on a dl580 g5 with a raid controller p-400

the write on the local drive is so slow

 

here is the reslut of the exchange best practice analyser

 

The 90th percentile for counter 'LogicalDisk(C:) Avg. Disk sec/Write' on server s900map0010.corp.bdc.ca is 8.941 (8941ms). The maximum value reported is 9.979 (9979ms).

The 90th percentile for counter 'LogicalDisk(D:) Avg. Disk sec/Write' on server s900map0010.corp.bdc.ca is 8.153 (8153ms). The maximum value reported is 9.148 (9148ms).

The 90th percentile for counter 'LogicalDisk(F:) Avg. Disk sec/Write' on server s900map0010.corp.bdc.ca is 8.785 (8785ms). The maximum value reported is 9.958 (9958ms).

 

 

and here is the config of the array diagnostic
