  • Patent number: 10382311
    Abstract: The disclosure is directed to benchmarking a server computer (“server”), e.g., a storage system of the server. The process can benchmark a candidate server using data from a production server that is handling live traffic of an application, e.g., a social networking application. The process includes collecting, from the production server, production data that is indicative of a workload of the production server, and generating a benchmark program using the production data. Upon execution of the benchmark program, the candidate server is made to process a workload generated based on the production data. The benchmark program records the performance of the candidate server, which is indicative of a performance of the candidate server in processing a workload similar to the production data. The performance results can be used in determining whether to upgrade the configuration of the production server to that of the candidate server, e.g., to improve performance.

  • Patent number: 10255163
    Abstract: Embodiments are disclosed for analyzing data storage devices. The present disclosure employs a “canary” test that selects multiple storage devices and tests the same for a predetermined period of time. By analyzing the statuses of the storage devices monitored and recorded during the applicable tests, the present disclosure can generate an analytical result regarding the characteristics of the storage devices. The analytical result can be presented to an operator in a meaningful way so as to enable him or her to make an informed decision when utilizing a storage device with characteristics similar to the tested storage devices.
