International Classification:

G06F 11/00
G06F 11/10
G06F 11/20

US Classification:

714 4, 714 5

Abstract:

A system identifies one or more devices having faults in a communication loop. The system includes an interface, a decision module, and a connection processor. The interface is configured for sending requests for information to each device of the communication loop and for receiving responses to the requests. The devices may include computer disk drives for use in a storage system. The requests may include Read-Link Status (RLS) commands sent to the computer disk drives. The RLS commands may provide diagnostics of the disk drives connected to the loop. The decision module is communicatively connected to the interface for weighting the responses of each device to identify the devices having the faults. The responses may be weighted based on the relative potential for disrupting operability of the system. The communication loop may include an FC loop that allows communications between a host system and the computer disk drives.

International Classification:

G06F 15/16

US Classification:

709233, 709228, 370229

Abstract:

The present invention discloses a system for adjusting the speed of operation of a channel for communicating with disk drives in a multi ported system, comprising a bridge controller having a first channel and a second channel and a plurality of enclosure services modules, each having a first channel connected in sequence from a bridge controller to a first enclosure services module and successively connected to successive enclosure services modules to a last enclosure services module and each having a second channel connected in reverse sequence from the bridge controller to the last enclosure services module and successively connected to the successive enclosure services modules to the first enclosure services module. In the disclosed method for changing the speed of operation of a channel, a change speed is performed on either the first or second channel and the other of the first and second channel is used to send change speed frames from the bridge controller to each of the plurality of enclosure services modules.

LSI Corporation - Milpitas CA

International Classification:

H04J 3/16

US Classification:

370468, 3702301

Abstract:

The present invention provides systems and methods for balancing a request load on device communication channels. A system includes a channel scanner, a processor, and a load balancer. The system may iteratively balance the request load on the communication channels. The device communication channels are typically connected between controllers and a system of devices. The channel scanner is configured for scanning the channels to determine the number or bandwidth of requests of each device. The processor may rank the devices by the number or bandwidth of requests of each device. The load balancer may allocate the requests between the channels based on the rank of the devices. For example, the load balancer may receive the rank order of the devices from the processor and allocate the requests based on the rank order. The load balancer may additionally allocate the requests based on present capabilities of the channels.

Abstract:

The present invention is directed to a method and apparatus for identifying IPsec security policy in iSCSI. In an exemplary aspect of the present invention, a method for identifying IPsec security policy in iSCSI includes the following steps. An IP address may be allocated to a physical port of an iSCSI network entity. The physical port may include at least one TCP listening port. For a discovery session, the IP address may be statically allocated (or permanently leased). For a normal session, the IP address may be statically allocated or DHCP assigned. A TCP listening port associated with the IP address in an iSCSI portal may then be used to link a security policy on an IP connection with iSCSI configuration.

US Classification:

726 1

Abstract:

The present invention is directed to methods for defining and naming iSCSI targets using volume access and security policy. In an exemplary aspect of the present invention, a method for defining an iSCSI target using volume access and security policy may include the following steps. One or more volumes of a network entity may be first mapped to an initiator. The mapping defines the unique Logical Unit Number for the volume to an initiator. Then, a security level may be defined for access to each volume accessed by the initiator. The subset of mappings for each initiator may be given any unique name. Next, the mapping and security subsets may be used to define the fully qualified targets with which the initiator may open a session.

Abstract:

A method may include defining an interface class including a static member having an implementation pointer. The method may also include loading a main code segment including a stub implementation of the interface class. Additionally, the method may include instantiating the stub implementation of the interface class to provide a stub implementation object. The stub implementation of the interface class may include a first constructor configured to set the implementation pointer to the stub implementation object. Further, the method may include loading a dynamic library including a real implementation of the interface class. Still further, the method may include instantiating the real implementation of the interface class to provide a real implementation object. The real implementation of the interface class may include a second constructor configured to set the implementation pointer to the real implementation object.
