Method and System to Detect Defective SFP Transceiver in a SAN Environment
Disclosed is a method and system for tracking performance of a Small Form-factor Pluggable (SFP) transceiver in a Storage Area Network (SAN). The method and system includes detecting bad frames received from a SFP transceiver, keeping a record of the detection and comparing the records with a pre-defined threshold. Once the pre-defined threshold is crossed, then the SFP transceiver is identified as a defective SFP transceiver and an error message may communicated to the customer using the defective SFP transceiver. Additionally, the defective SFP transceiver may be the first candidate for replacement in case of any failure in the SAN fabric. The identification of defective SFP transceiver may be indicated via one or more of an LED housed on the SFP transceiver itself and via a central management point. The central management point may utilize a central management tool such as one or more of a fabric manager or Transmit Power Control (TPC) manager to monitor the performance of SFP transceivers in a SAN. Such central management tools may include an interface to display the defective SFP transceiver.
In an embodiment, an LED housed on a SFP transceiver may be used for depicting a defective SFP transceiver. Initially, an agent monitors performance of the SFP transceiver in a SAN. The agent detects bad frames such as one or more of CRC error, corrupt header info and any other pre-defined bad frame received from an SFP transceiver in the SAN. Upon receiving a bad frame from the SFP transceiver, the agent increments its counter by 1. Alternatively, the agent may add a new bit or use a reserved bit field and set a bit to a pre-defined value to acknowledge detection of the bad frame. Thereafter, the counter is compared to a...
