Abstract: In one embodiment, a system includes non-volatile memory (NVM) configured to store data, a memory controller connected to the NVM via a NVM interface, a network interface card (NIC) connected to the memory controller, a processor, the logic being configured to: initiate cluster parameters that govern how a NVM cluster will function and operate, multicast cluster parameters of the NVM cluster at predetermined intervals to any other node in the NVM cluster, and map submission and completion queues of any shared NVM on other nodes in the NVM cluster to the memory controller based on details of the shared NVM on the other nodes in the NVM cluster, wherein the submission queue is configured to store commands to access the shared NVM and the completion queue is configured to store completed commands after being processed through the submission queue.

Abstract: In one embodiment, a method includes initiating cluster parameters that govern how a non-volatile memory (NVM) cluster functions and operates. Submission and completion queues of shared NVM on other nodes in the NVM cluster are mapped based on details of the shared NVM on the other nodes in the NVM cluster. The submission queue is configured to store commands to access the shared NVM according to a first-in-first-out (FIFO) scheme. The completion queue is configured to store completed commands after being processed through the submission queue. In another embodiment, a host-based data storage system includes NVM configured to store data. The host-based data storage system further includes a processor and logic integrated with and/or executable by the processor to perform the foregoing method.

Abstract: Systems and methods are provided for overlaying a virtual network on a physical network in a data center environment. An overlay system is arranged in an overlay virtual network to include an overlay agent and an overlay helper. The overlay agent is implemented in an access switch. The overlay helper is implemented in an end station that is in communication with the access switch. Overlay parameters in compliance with an in-band protocol are transmitted between the overlay agent and the overlay helper.

Abstract: In one embodiment, a system includes at least one processor and logic integrated with and/or executable by the at least one processor, the logic being configured to receive, by the at least one processor, a request to assign a media access control (MAC) address to a device on a port, determine, by the at least one processor, the MAC address to assign to the device based at least partially on the port, and send, by the at least one processor, a response to the request with the MAC address. According to a further embodiment, the logic may be configured to create a MAC address allocation table that includes a plurality of hash values, each hash value being associated with one port and a plurality of MAC addresses, wherein the assigned MAC address is one of the MAC addresses associated with the port in the MAC address allocation table.

Abstract: A method for providing location independent dynamic port mirroring on distributed virtual switches is disclosed. A controller is provided to configure one or more virtual switches within a group of physical machines to appear as a set of distributed virtual switches. In response to the receipt of a data packet at a port of a physical machine, a determination is made whether or not the port has a monitor port located on the physical machine. If the port has a monitor port located on the same physical machine, a copy of the data packet is sent to the monitor port of the physical machine. If the port has a monitor port located on a different physical machine, a copy of the data packet along with an identification (ID) of the port and an ID of the monitor port are encapsulated, and the encapsulated information are sent to a controller.
