This object tracks the megabytes this specific authorized remote initiator has written to this specific local target, scoped to that one initiator-target pairing. Paired with ciscoScsiAuthIntrReadMegaBytes, an admin gets a per-host read/write bandwidth breakdown against a shared target, useful for identifying exactly which one host among several sharing an array is driving a write-heavy or read-heavy load pattern that is affecting overall array performance. A backup server's authorized-initiator entry showing dramatically higher write megabytes than any other host attached to that same target would confirm it as the dominant write workload on that array during backup windows.
