An apparatus operable with a host and a data storage component for detecting a storage device susceptible to failure under IO workload is provided. The resultant signals are sensed 11 and utilized to establish 13 a corresponding angle of movement and to establish 15 magnitude of movement for an on-screen display indicator such as an on-screen cursor 61. Various performance metrics associated with the operation of the network and the application server are measured during the testing of the server, and these metrics are stored for later access by an analysis module. Finally, the hydrogen is chilled by a hydro-evaporation cooler and then compressed by a hydrogen compressor. An axial screw engaged through the disk and ring with the bolt engages axially inward with the disk to press the disk against the leg and the leg against the housing.
