Hi: Thanks everyone for the guidance and pointers. To summarize, T10 is a mechanism to ensure the integrity of data read/written from/to the storage device. iSCSI is just *a* transport mechanism to carry the data between initiator and target. A followup question: I understand that T10 mechanism adds extra 8 bytes to 512 byte block. This operation is done before data is actually written to the storage device (at the target in iSCSI terminology). Is this understanding correct? Thanks again, Vishal.

T10 data protection simply changes slightly the content and length of the data fields sent to and received from the storage device. It also modifies the behavior of some commands, depending on the checking level selected for the data protection mechanism. That is described in the T10 standard SBC-2 (and SBC-3, now in development). It has no effect on the iSCSI protocol itself and is completely independent of RFC 3720.

I couldn't find any reference to T10 data protection inside RFC 3720. Pardon my ignorance if this is stupid question...I am quite new to the storage area. Thanks, Vishal.
