Experience

  • Cisco Webex Meeting Server IOPS Measurement - Testing Storage Performance (Development)
    https://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/2_0/Planning_Guide/Planning_Guide_chapter_00.html#reference_39CA21773C2B4CC795075FD7DCFCA25B

    Task was to develop comprehensive test plan from scratch, execute, measure and analyze final results of Cisco Webex Meeting Server IOPS (Input/Output per second) usage while performing different operations under certain load.

    It was challenging to find a way to measure IOPS and understand how EMC storage disks are configured and shared among Cisco B series servers.

    Some paid solutions for IOPS tracking didn't provide proper values (polling interval was too high, with no option to set polling interval), so I had to find a way to take data from ESXi directly.

    For more details about results refer to tables in section "IOPS and Storage System Performance", in the link below.
