A system to facilitate operating system (OS) installation is described. The system includes a server and rack controller, including one or more processors to generate an imaging service comprising an OS image container, transmit data via a first network to initiate a boot up process at a server and download an OS image included in the OS image container via a second network, wherein the second network is separate from the first network.

Operating system installation mechanism

Providing power to a server includes a switch with power sourcing equipment (PSE) and a server with a network interface controller (NIC) the PSE to transfer power to the NIC of the server via a network cable to change configuration settings prior to the server booting from a stand-by mode.

Embodiments of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for network virtualization can include providing, by a datacenter () having physical and/or virtual resources, a number of virtual tenant datacenters (tDatacenters), each tDatacenter being isolated from other tDatacenters. A tenant virtual local area network (T-VLAN) () is associated to each of the number of tDatacenters, and a value of an end-to-end invariant network virtual local area network (VLAN) identification (VID) label (T-VID) is associated to a particular T-VLAN (). A network packet associated with the particular T-VLAN () is modified at an edge network boundary () to include the T-VID. The T-VID is configured to have more than 4096 possible values.

Network virtualization

Examples disclosed herein relate to associating an identifier for a virtual machine with a published network configuration service type. Examples include configuring an edge switch with a network policy in response to receiving the identifier from the edge switch.

One example provides a network device including a queue to receive frames from a source, a processor, and a memory communicatively coupled to the processor. The memory stores instructions causing the processor, after execution of the instructions by the processor, to determine whether a flow control threshold of the queue has been exceeded, and in response to determining that the flow control threshold of the queue has been exceeded, generate a message to be sent to the source of the frame that exceeded the flow control threshold. The message includes a pause duration for which the source is to stop transmitting frames.

Flow control in a network

Systems and methods for distributed configuration of one or more network interface cards (NICs) are disclosed. An exemplary method comprises issuing a request frame including at least a current configuration generation for the NICs from a host computing device to a network device. The method also comprises returning at least one configuration frame including a newer network configuration for the NICs from the network device to the host computing device. The method also comprises configuring the NICs at the host computing device with the newer network configuration.

Distributed configuration of network interface cards

Embodiments of the present invention are directed to providing configurable transmission rates for devices within a multi-device enclosure, despite common communication media within the multi-device enclosure that would otherwise constrain or fix the transmission rates of the devices. In one embodiment of the present invention, implemented within a virtual-connect manager or other module or device contained in, or associated with, a multi-server enclosure, the virtual-connect manager provides an administrative or management interface through which each server can be assigned a maximum transmission rate. The virtual-connect manager then continuously monitors the transmission rates of servers and/or ports within servers in order to apply back pressure, or flow control, so that the servers and/or ports within servers do not exceed the configured maximum transmission rates.

A system comprises a processor and a graphical user interface (GUI) executable by the processor. The GUI enables a user to specify constituent virtual connect domains (VCD) for a common VCD group. Each VCD comprises two or more computing devices virtualized by a virtual connect device. The virtual connect device comprises multiple ports for communicatively coupling the two or more computing devices to external networks. For all of the constituent VCDs of a particular VCD group, each corresponding port of a corresponding virtual connect device is connected to the same external.

A system and method are provided for interfacing a Fiber Channel network to an Ethernet based network. The method includes the operation of establishing a connection between a Fiber Channel device and an NPIV interface in an Ethernet interconnect module (). Another operation is processing a fabric login from a server on the Ethernet based network, along with a server identifier that is sent to the Fiber Channel device (). Acknowledgement frames for fabric login from the Fiber Channel device can be examined in order to identify the N_Port ID of the server (). In another operation, the server's MAC address can be retrieved from a table using the N_Port ID (). Then an Ethernet packet can be sent to the server using the server MAC address (). The Ethernet packet contains a Fabric Provided MAC Address used to enable the server to communicate with the Fiber Channel device.

A network comprising a first electronic device associated with a first profile that uniquely identifies the first electronic device on the network. The network also comprises a second electronic device coupled to the first electronic device. The first profile is migrated to the second electronic device such that the first electronic device is no longer associated with the first profile and such that the first profile uniquely identifies the second electronic device on the network.

A computer system has an aggregated plurality of hybrid network resources. The hybrid resources support both offloaded connections with a first set of clients and conventional connections with a second set of clients. The conventional and offloaded connections are established through a common physical connection to a network. A unique protocol address is assigned to each of two or more active ones of the resources. A virtual layer2 device is exported for each of the two or more active resources. The assigned protocol addresses are exposed to a protocol stack residing in the operating system of the computer system. Each of the assigned protocol addresses are exposed through and associated with the virtual device exported for the one of the active resources to which the protocol address is assigned. One or more of the conventional connections are established with the second set of clients through the active resources and their respective virtual devices.

Aggregation of hybrid network resources operable to support both offloaded and non-offloaded connections

A computer system aggregates a plurality of network resources of a computer system. The computer system has a plurality of processing nodes. Each of the processing nodes includes one or more of the plurality of network resources. The one or more resources of each processing node makes up a bypass protocol stack operable to provide offloaded connections over a network to instances of one or more applications running on the system. Each of the applications is uniquely associated with a first port number. The system is identified on the network by a global IP address and each of the plurality of nodes is identified by a unique local IP address. Each of the plurality of resources is uniquely identified by an assigned private IP address. At each of the processing nodes, a listening socket is created for each instance of the plurality of applications running on the node. The listening socket is created by associating it with a first endpoint tuple that includes the public IP address uniquely identifying the node and the first port number associated with the application for which the listening socket is created. The first endpoint tuple associated with each listening socket created is translated to a set of bypass endpoint tuples, each of the set of bypass tuples including a different one of the assigned private IP addresses identifying the one or more network resources of the node. Each listening socket is associated with the set of bypass tuples. A global address translation map is maintained for each set of bypass tuples associated with each of the listening sockets created for an instance of each of the applications running on the plurality of processing nodes.
