Abstract
A congestion and failure detector and localizer running on a storage array locally monitors ports of the storage array for IO failures and local link errors and remotely monitors ports of host initiators and host-side and storage array-side switches for link errors. Based on whether the local link error rate is increasing at any ports, whether IO failures are associated with a single host initiator port, and whether link error rate is increasing on both the host initiator and initiator-side switch, the congestion and failure detector and localizer generates a flag indicating either a physical link problem between the storage array and adjacent switch, ISL physical issue or spreading congestion, host initiator-side physical link problem, or path congestion. The flag identifies the storage array port, issue type, link, fabric name, and host initiator.
