This object tracks the megabytes this specific authorized remote initiator has read from this specific local target, scoped to that one initiator-target pairing. An admin allocating storage bandwidth fairly across multiple hosts sharing one array uses this per-pair figure to see exactly how much of the target's total read bandwidth one particular host is consuming, informing decisions about QoS or workload rebalancing if one host is dominating. A single host's read-megabyte figure representing the majority of a target's total read traffic would justify moving that workload to a dedicated LUN or array.
