Abstract
A system and method for controlling the performance of one or more target devices. A connection request for a target device of a plurality of target devices is received at a serial attached SCSI (SAS) Expander from an SAS initiator device, wherein a maximum performance availability value is associated with the target device. If the current performance availability value of the target device indicates that the target device does have availability to service the connection request, the connection request from the SAS initiator device is accepted and a connection is established between the SAS initiator device and the target device. Alternatively, if the current performance availability value of the target device indicates that the target device does not have availability to service the connection request, the connection request from the SAS initiator device is rejected and a connection is not established between the SAS initiator device and the target device. Traffic flow between the devices is measured and the current performance availability value of the target device is updated to control the performance of the target device.
