Abstract: A first cloud computing device includes a first virtual machine, and receives, from the first virtual machine, a packet destined for a second virtual machine provided in a second cloud computing device. The device appends, to the packet, a header that includes an address of the second cloud computing device, a virtual local area network (VLAN) identifier of the first virtual machine, and a VLAN identifier of the second virtual machine. The device provides the packet and the header to a cloud computing network for provision to the second virtual machine.

Abstract: A device, of a cloud computing environment, includes a virtual network device that receives a packet with an address, and determines whether the packet is a broadcast packet or a unicast packet. The virtual network device processes the packet based on whether the packet is a broadcast packet or a unicast packet. The packet is transmitted to local address(es) or remote address(es) when the packet is a broadcast packet. The local address(es) is associated with at least one hardware component of the device, and the remote address(es) is associated with at least one other device, of the cloud computing environment, that is separate from the device. The packet is transmitted based on whether the address, of the packet, matches the local address(es) or the remote address(es) when the packet is a unicast packet.

Abstract: A system and method of operation is disclosed describing migration, management, and operation of applications and servers from customer data centers to cloud computing platforms without modification to existing environments or user access procedures. A cloud isolation layer operates as a virtual layer on the cloud platform, enabling server operation in a virtual environment that appears the same as the prior local environment. A cloud software image and a local cloud gateway act to redirect existing addressing from the local environment to the cloud implementation through secure network and data paths. A local management application provides a control interface and maps and manages the local environment and utilized cloud resources.

Abstract: A system and method for rapidly zeroing/clearing a container in a redundant array of independent disks (RAID) provides the writing of a series of logical zeros to each disk in the container using an internal bus driver-level command. The command causes a small data block of all zeroes written to the disk to be duplicated so that the entire container space in each disk is effectively written-to. The bus driver is preferably a small computer system interface (SCSI) architecture that supports a WRITE SAME command. Where the disk device fails to support the WRITE SAME command then an alternative process is employed, in which a single large sized memory block is created and initial sized with all zeroes. A predetermined number of virtual scatter gather elements are created, each pointing to the memory block.
