We tried to locate the checksum value on object's metadata resides on EMC storage without luck.

 

Thus, we tried to leverage on the Atmos-php method to ReadObject from EMC storage to perform the checksum value calculation as below:

 

	$ck = new Checksum( 'SHA0' );
	$ck->update( $_files->ReadObject($id, null, null, null) );

 

Unfortunately, this is not an efficient/acceptable way especially on huge file. As this will incur bandwidth to download the object to perform such checksum calculation.

 

Please advise is there a way to perform this checksum calculation at EMC storage end without download it back locally?

Thank you.
