Abstract:

Techniques for transmitting data may include: receiving, at a host, an initiator data transfer rate indicating a communication rate at which an initiator port of the host communicates over a first path using a communications fabric with a target port of a data storage system; receiving, at the host, a target data transfer rate indicating a communication rate at which the target port of the data storage system communicates over the first path using the communications fabric with the initiator port of the host; determining, at the host, whether the initiator data transfer rate and the target data transfer rate are different; and responsive to determining that the initiator data transfer rate and the target data transfer rate are different, performing processing that limits a rate at which data is transmitted between the initiator and target ports in accordance with the initiator and target data transfer rates.
