hi Bourkaib

even your title says P400 I think we are talking about 642 controller since that what it says in your ACUCLI

your cache can not be configured since
""Cache Status: Not Configured
Accelerator Ratio: 100% Read / 0% Write
Total Cache Size: 64 MB""

your controller has the basic cache 64 MB in order to be able to configure it you need to get more cache:

128-MB BBWC (Battery-Backed Write Cache) Enabler NOTE: This 128MB BBWC supports the Smart Array 641 Controller and Smart Array 642 Controller.
351580-B21
