Appl. No.:

12/582269

Assignee:

Dell Products, LP - Round Rock TX

International Classification:

G06F 15/16
G06F 15/173
G06F 15/177

US Classification:

709223, 709226, 709213

Abstract:

A storage area network (SAN) includes a management server, a storage device, and a management station coupled to a fabric. The management server implements device domains on the SAN. The storage device instructs the management server to add new device domains on the SAN. The management station defines the new device domains to include the storage device and an initiator coupled to the fabric, and directs the storage device to instruct the management server to add the new device domains. A method includes coupling a management server to a SAN fabric, implementing device domains in the management server, defining a new device domain that includes a storage device and an initiator coupled to the SAN, and coupling a storage device to the SAN fabric, the storage device being operable to instruct the management server to add the new device domain.

International Classification:

G06F 12/00

US Classification:

709226, 709250

Abstract:

A network of data processors for providing access to a resource, such as implemented a Storage Area Network that uses iSCSI and Microsoft MPIO-based network communication protocols. In preferred embodiments, the system or method uses (a) target-side consideration of MPIO disk structures, such as by having iSCSI initiators in from iSCSI targets via an iSCSI session object that is settable by a service action; and/or (b) uploading of routing tables from iSCSI targets to iSCSI initiator(s), such as to a Device Specific Module (DSM). Implementations may also involve, in a preferred embodiment: (1) requesting that the contents of the routing table be provided from the iSCSI target side storage servers to the iSCSI initiators, and using this as one of the factors influencing path selection as performed in the MPIO DSM on the initiator side; and/or (2) transmitting information from the iSCSI initiator to the iSCSI target storage server identifying connections as belonging to the same MPIO disk, and then receiving back from the iSCSI target storage server, information about the connections that should be created, and further then having a connection load balancer on the storage server handle those connections as related connections that need to be assigned each to a different Network Interface (NIC) on the storage servers.

International Classification:

G06F 12/16

US Classification:

711162000

Abstract:

Systems and methods for providing an efficient partitioned resource server are disclosed. The partitioned resource server includes a plurality of individual servers, and the individual servers support a storage service. The systems and methods provide archiving processes for partitioned resources. To this end, the systems and process include a snapshot process operating on a server and capable of coordinating with other snapshot processes operating on the other servers for generating state information representative of the state of the partitioned resources.

Assignee:

Dell Products, LP - Round Rock TX

International Classification:

H04L 12/24

US Classification:

709223

Abstract:

A storage device coupled to a fabric includes a memory and a processor operable to receive, default domain information for a storage area network (SAN) from a management server coupled to the fabric. The default domain information including a list of host systems and a list of initiators on the SAN. The processor also sends the default domain information to a management station to configure a discovery domain including a host system selected from the list of host systems and an initiator selected from the list of initiators, receives the discovery domain from the management station, directs the management server to add the first discovery domain to a list of device domains implemented by the management server on the SAN, and directs the management server to enable the first discovery domain.
