Systems and methods in accordance with various disclosed embodiments can manage a mirrored virtual target to synchronize the members of the virtual target and / or to verify that the members of the virtual target are synchronized. In one embodiment, a mirrored virtual target is synchronized by first provisioning at least one first internal virtual logical unit (IVLU) corresponding to at least one destination target of the mirrored target and a second IVLU corresponding to a source target of the mirrored target. A write command is first issued, via one or more internal virtual logical units, to each of the destination target members of the mirrored target. When each destination target is available to receive data, as evidenced by a returned transfer ready signal, a read command is provided to the source target via the second internal virtual logical unit. In this manner, a data path between the source and destination targets is established prior to reading data from the source target. Accordingly, the data can be read from the source target, converted to write data, and routed to the destination targets at line speed without buffering of the data. A similar process is provided to verify that the members of a mirrored target are synchronized. In one embodiment, a system and method is provided to manage incoming commands for the mirrored target while synchronizing or verifying synchronization of the mirrored target. Incoming commands can be queued as they are received and provided to the mirrored target when pending synchronization or verification commands are completed.

The data such as beacon information is employed to generate a table ranking the alternate channels in terms of viability for communications.

A method, programmed digital computer and computer program product for assessing and managing security risks in an iterative fashion is provided. The invention is adaptable for use with any system with security targets that are accessible to a security threat. The invention is applicable to all systems with physical, electronic and virtual targets that can be accessed by a threat, thus creating a risk to the system, e.g., systems surrounding hospitals, blood banks, mass transit operations, power production and transmission facilities, communication systems, internet service providers, email and web hosting service providers, electronic commerce, financial institutions and school district lunch programs. Under the invention, if a security threat can access a security target within a system then a risk to the system is present. The invention provides an iterative process by which the system may be analyzed as an undivided whole or may, alternatively, be divided into discrete sections where all known security targets are identified within each section. All threats to each individual target are then identified and it is determined whether each threat has access to the associated target. If access is present, a qualitative or quantitative risk level is assigned. Then, appropriate countermeasures are considered and, where appropriate, implemented if the risk level is unacceptably high. A second inquiry is made regarding whether the particular threat has access to its identified target, considering the implemented countermeasure(s), and a second risk level assignment performed. If the risk level remains high, the process is repeated until the risk level for the subject target is acceptably low. All remaining targets are secured in this manner.

The request is a command to perform first processing and the request is sent from a client over a virtualized path. The virtualized path includes a virtual target port of the data storage system. The virtual target port is a first physical target port that provides a virtualized counterpart port for a second physical target port whereby requests directed to the second physical target port are routed to the first physical target port rather than the second physical target port. First processing is performed and a response to the request is generated. The response includes first information consistent with sending the request over a non-virtualized path to the second physical target port. The response is sent to the client.

The processing arrangement calculates a distance in time from the equipped vehicle to a virtual target vehicle, the distance to and velocity of the virtual target vehicle being calculated on basis of the number of vehicles in the group, the spread in distance of the group, and thus the vehicle density of the group, and the variability of positions in the group, such that the algorithm of the processing means decides from the above parameters on the allowed deviations in time distance, wherein the processing arrangement is arranged to produce a signal to the velocity control arrangement based on the calculated distance in time between the equipped vehicle and the virtual vehicle.

Systems and methods can provide mirrored virtual targets and online synchronization and verification of the targets while avoiding deadlock, inconsistencies between members of the target, and false verification failures. A lock within the storage switch can limit the number of outstanding commands for a physical target to one during synchronization and verification operations. In one embodiment, a lock can be implemented as one or more resource tables maintaining an indication of the number of transfer ready signals available from physical targets. During typical write operations, deadlock can be avoided by determining whether each physical target for the mirrored operation can issue a transfer ready signal prior to issuing a command to the physical target. When a synchronization or verification operation begins, the maximum available number of transfer ready signals for each target can be decremented to one in order to limit the total number of outstanding commands for each target to one.
