Abstract:

A method, computer readable medium, and system that handles a multi-protocol name in a virtualization environment includes determining and predicting with a virtualization management computing device when a name collision occurs between content names of different content accessible by two or more protocols. The virtualization management computing device restricts access to the different content in one or more network attached storage devices when the name collision is determined to occur to one or more of the protocols which can distinguish the different content. It preserves access to the different content in certain cases where the collision can be predicted.

Abstract:

Systems and methods are described for providing queue pair numbers for a queue pair to more effectively track and manage the frequency of use and re-use of queue pair numbers on a queue pair context basis in an InfiniBand™ device. The present invention uses a counter for each queue pair context to set the changeable portion of the queue pair number. A reference count for each queue pair context is also used to track the quantity of queue pair numbers currently allocated to a queue pair context. The present invention sets, tracks and manages the values of the counter and the reference count for each queue pair context in conjunction with queue pair operations to provide a systematic queue pair numbering scheme. By tracking and/or setting values of the counter and reference count for a queue pair context, the present invention re-uses queue pair numbers efficiently and in a predictable and repeatable manner.
