Abstract: The present disclosure relates to methods and apparatus for testing the true capabilities of devices connected to a computer. Methods consistent with the present disclosure may include generating test commands to send to a data storage device under test while storing information related to the commands sent to the data storage device in a low latency buffer. The low latency buffer may temporarily store command related data while data from a plurality of commands are organized and persistently stored in memory of a persistent data storage device. The low latency buffer may include or be comprised of high speed random access memory and the persistent data storage device may be a solid state drive or hard disk drive. Preferably, the persistent data storage device will store command test sequences that span long periods of time of hours or days.

Abstract: A method and apparatus to manage storage devices has been disclosed. In one embodiment, the method includes logically partitioning each of a number of storage devices in a networked data storage system into segments and managing the segments in response to how often each of the storage devices is accessed. Other embodiments are described and claimed.

Abstract: A portable microprocessor controlled transmission impairment measuring unit capable of operating as a master unit or a slave unit and responsive to digital or manual control measures all basic parameters necessary to characterize a voice channel for its ability to transmit data traffic, as defined by Bell System Technical Reference PUB41009, dated May 1975. Measurements can be made manually end-to-end with a unit at each end of a circuit to be tested; manually looped-back with a unit at one end of the circuit; or remotely from one end with a MASTER operated unit controlling a SLAVE operated unit with all measurements displayed on the MASTER unit. The unit can also be used as a voice frequency repeater and can be operated with other test sets and computers having compatible measurements and capabilities.All measurements are displayed on digital readouts. Two separate readouts allow simultaneous display of up to two different parameters.
