Abstract: The present disclosure relates to a method and a system for performing secure read/write operations in the pluggable flash storage device. In one embodiment, a request for at least writing and reading of data in/from the pluggable flash storage device is received. Upon receiving the request for writing data, the storage device is authenticated based on a predetermined signature of the pluggable flash storage device. Upon authenticating the storage device, the at least one of user and the storage controller who made the request is also authenticated and write operation is performed based on successful authentication of the at least one of the user and the storage controller. By way of establishing secure communication between the storage device and the user or the storage controller during the read/write operation the hacking of the data in the storage device or use of the storage device with wrong intent is avoided.

Abstract: A system and method for port performance ranking in a multi-protocol switch includes monitoring one or more first parameters, the one or more first parameters associated with operating condition of one or more ports of the multi-protocol switch. Each of the one or more first parameters is compared with an associated predefined criterion to determine deviation from the associated predefined criterion. One or more eligible ports is determined from the one or more ports based on non-deviation of each of the one or more first parameters from the associated predefined criterion. For each of the one or more eligible ports, each of one or more second parameters is compared with an associated predefined threshold, the one or more second parameters associated with port traffic statistics. The one or more eligible ports are ranked based on the comparison between each of the second parameters and the associated predefined threshold.

Abstract: A method, non-transitory computer readable medium, and device that sends an outgoing storage device frame to a storage device, the outgoing storage device frame converted from an incoming storage device frame received from a host device based on a protocol supported by the storage device. An incoming host device frame is received from the storage device in response to the outgoing storage device frame. Whether an outgoing host device frame has been sent to the host device is determined, the outgoing host device frame converted from the incoming host device frame based on a protocol supported by the host device, wherein the protocol supported by the host device requires a different frame sequencing than the protocol supported by the storage device. A next incoming storage device frame received from the host device is retrieved when the outgoing host device frame is determined to have been sent to the host device.
