Fault prediction and detection using time-based distributed data

A computing device comprising:

• one or more processors;
• a memory in communication with the one or more processors, the memory having computer-readable instructions stored thereupon which, when executed by the one or more processors, cause the computing device to perform operations comprising:
• determining a time-distributed read/write latency performance profile for a storage device, the time-distributed read/write latency performance profile determined based on one or more read/write latency metrics for the storage device;
• based on the time-distributed read/write latency performance profile and a characteristic time-distributed read/write latency performance profile for a representative group of storage devices having common characteristics with the storage device, determining that a probability that the storage device will enter a fault state exceeds a predetermined threshold;
• and
• based on the probability that the storage device exceeding the predetermined threshold, redirecting read/write requests for the storage device to other storage devices.

A non-transitory computer-readable medium having encoded thereon computer-executable instructions that, when executed, cause one or more processing units of a computing device to execute a method comprising:

• collecting read/write latency data for input/output operations executed at a storage device of a group of storage devices of a storage network;
• based on the collected read/write latency data, determining a time-distributed read/write latency performance profile for the storage device;
• determining a characteristic time-distributed read/write latency performance profile for a representative group of storage devices having common characteristics with the storage device;
• determining that a difference between the time-distributed read/write latency performance profile for the storage device and the characteristic time-distributed read/write latency performance profile exceeds a predetermined deviance threshold that is indicative of the storage device entering a fault state;
• and
• in response to determining that the difference exceeds the predetermined deviance threshold, redirecting read/write requests for the storage device to other storage devices.
