IDENTIFYING SLOW DRAINING DEVICES IN A STORAGE AREA NETWORK

摘要

A link in a storage area network (SAN) is identified that is being affected by one or more slow draining devices. Devices in the SAN are identified as candidates for potentially being a slow draining device affecting the link. For each identified candidate device, metric data is identified that describes, for example, traffic activity of the candidate device, such as data transmission rates of the candidate device. Additionally, metric data is identified for the link. For each candidate device, a correlation value is determined that indicates the likelihood that the candidate device is a slow draining device affecting the link. The correlation value of a candidate device is determined based on the correlation between the metric data of the device and the metric data of the link. One or more of the correlation values are presented to a user via a user interface.

1. A computer-implemented method comprising:
identifying a link in a storage area network affected by one or more slow draining devices; identifying metric data for each of a plurality of candidate devices in the storage area network, each of the plurality of candidate devices potentially being a slow draining device affecting the link; determining, for each of the plurality of candidate devices, a correlation value indicative of a likelihood that the candidate device is a slow draining device affecting the link, the correlation value determined based on correlation between the metric data identified for the candidate device and metric data associated with the link; and storing one or more of the determined correlation values.
