摘要:
In information storage systems in which data retrieval requires movement of at least one physical element, a measurable amount of time is required to reposition that physical element in response to each data write or read request. After selecting one or more data requests for dispatch based solely on an approaching or past due time deadline, additional requests are identified for data to be read or written to locations which are in close proximity to previously scheduled requests, previously selected additional requests, or the present position of the moveable physical element, obviating the need to expend the full amount of time required to accelerate the physical element and then decelerate the physical element to position it over the desired area within the information storage system. In this manner, data may be transferred to or retrieved from an information storage system more efficiently with less expenditure of time.

The forgoing objects are achieved as is now described. In information storage systems in which data retrieval requires movement of at least one physical element, a measurable amount of energy and time are required to reposition that physical element in response to each data write or read request. After selecting one or more data requests for dispatch based solely on an approaching or past due time deadline, additional requests are identified for data to be read or written to locations which are in close proximity to previously scheduled requests, obviating the need to expend the full amount of energy and time required to accelerate the physical element and then decelerate the physical element to position it over the desired area within the information storage system. In this manner, data may be transferred to or retrieved from an information storage system more efficiently with less expenditure of energy and time.
摘要:
A method for sharing a network connection between a host system and a virtual machine is disclosed. The method includes sending an outgoing data frame from the virtual machine to a computer network. The host system is enabled to use the network connection using a first layer 2 address and a first layer 3 address. The first layer 2 and the first layer 3 addresses are associated with the network connection. The virtual machine is enabled to attempt to use the network connection using a second layer 2 address and a second layer 3 address. The first layer 3 and the second layer 3 addresses are compliant with IPv6. An occurrence of the second layer 2 address is replaced within the outgoing data frame with the first layer 2 address. If the outgoing data frame includes a network discover protocol (NDP) message of a selected type, the second layer 2 address in the NDP message is replaced by the first layer 2 address.

A method for sharing a network connection between a host system and a virtual machine includes receiving an incoming data frame. The host system is enabled to use the network connection using a first layer 2 address and a first layer 3 address. The first layer 2 and the first layer 3 addresses are associated with the network connection. The virtual machine is enabled to attempt to use the network connection using a second layer 2 address and a second layer 3 address. The first layer 3 and the second layer 3 addresses are compliant with IPv6.
摘要:
A method of data communication between a first virtual machine and a second virtual machine is disclosed. The second virtual machine is executing in a record/replay mode. Data from the first virtual machine is copied to a first queue. The first queue receives the data from the first virtual machine. The first queue has a header section and a data section, wherein the header section being write protected and stores a tail pointer of the data in the first queue. The tail pointer is updated in the header section. This update of the tail pointer causes a page fault, which is handled-through a page fault handler. The handling includes copying the data from the first queue to a second queue. The second queue being configured to receive a copy of the data and to allow the second virtual machine to access the copy of the data.

Embodiments provide a network address translation (NAT) service for network devices. A network connection from at least one private network device to the NAT service is received and a network connection from at least one remote device to the NAT service is received. The private network device is positioned within a private network and the remote device is positioned within a public network. A network availability of the remote device is determined. If the remote device is unavailable or a network configuration setting associated with the remote device changes, the private network device is notified and a connection reset message is transmitted to the private network device.
