Storage area network queue depth profiler

TL;DR: In this article, an example method for diagnosis and throughput measurement of FC ports in a SAN environment is provided and includes generating, by a control processor at a generator in the SAN, a control packet requesting a link test to be performed with a reflector, sending the control packet to the reflector through a media access controller (MAC) of the generator, receiving, at the MAC of the Generator, an acknowledgement from the Reflector indicating ability to perform the requested link test, generating, at a Generator, a test data packet for the Link test, performing the link test with

TL;DR: In this article, the authors present a storage map indicating the first association between the data storage module and the disk partition and indicating the second association between data storage modules and the tenant.

TL;DR: In this article, an example method for performance monitoring and troubleshooting in a storage area network (SAN) environment is provided and includes receiving, at a network element in the SAN, a plurality of frames of an exchange between an initiator and a target in a SAN.

TL;DR: In this article, the first network device receives a request for storage resources from a second network device, evaluates the willingness of the first device to provide the requested storage resources and assigns a willingness score based on the evaluating; determining whether the willingness score is greater than a minimum value; and if the willingness scores are greater than the minimum value, providing a response to the request from the first node to the second node.

TL;DR: In this paper, a data processing system that uses a non-volatile solid-state device as a circular log, with the goal of aligning data access patterns to the underlying, hidden device implementation, is described.

TL;DR: In this article, a quality-of-service controller and related method for a data storage system are prioritized by computing a target deadline for a request based on a monitored arrival time of the request and a target latency for its workload.

TL;DR: In this article, the authors present an approach for the collection of performance data at multiple servers in a SAN and forwarding that data to a centralized server for analysis, where a SAN diagnostics manager then pulls the collected data from each agent so that a picture of the SAN can be developed.

TL;DR: In this paper, a hierarchy of timing mechanisms cooperate to report errors at different operational levels of a complex of computing devices, and each timer is able to identify a failure condition at its own level of operation and transmit a time-out condition to a higher level device which may also be a timer.
