Double Caching

Hi,

Can somebody explain what is double caching ? Is this only on Unix or NT too.

Thanks in Advance.

an examle is :

Operating system cache and SCSI cache hold duplicate data.

Hi,

I did not understand what you said. Can you be little precise.

Thank You

What sureshy is talking about..is the fact that the OSe has cache where data is stored and the SCSI has its own cache where it stores data. We had this problem and we turned off the OS cache which increased our Throughput.
