Re: Convert Thin LUN to Dedupe

sunshuai,

Express Scan is used to prevent wasted CPU cycles, if a page is not compressible then it is written to disk uncompressed.  This is instead of compressing the entire page only to find out the data was not compressible and using resources to gain limited/no return.
