Hello,   No, thin provisioning won't affect performance as long as you have not over provisioned the array. When space exhaustion nears then IO is slowed down in anticipation of setting the volume(s) offline.   Thin provisioning on the array is simply not allocating all the space up front. A small amount of space is allocated ahead of time.   Then more space is allocated from the free pool to replace what was used keeping the allocated buffer intact.   It's often confused with thin provisioned VMDKs, especially before VMware implemented VAAI.  So a TP VMDK file had to be grown, the block wiped out then the write could occur.     Regards,  Don 
Hello everyone, I recently read in the IT magazine that Thin provisioning reduce array performane (IOPS). There was not mentioned about Dell EqualLogic solution, but this 'problem' relates to EqualLogic array?In our company, we're using EqualLogic PS6100 Series and practically we're using only volumes with thin provisioning enable.Regards,AdamErrot
