Systems And Methods For Dynamic Alignment Of Associated Portions Of A Code Word From A Plurality Of Asynchronous Sources
US Patent:
6385674, May 7, 2002
Filed:
Sep 20, 1999
Appl. No.:
09/399581
Inventors:
Kumar Gajjar - San Jose CA
Larry P. Henson - Santa Clara CA
Larry P. Henson - Santa Clara CA
Assignee:
MTI Technology Corporation - Anaheim CA
International Classification:
G06F 1100
US Classification:
710 62, 714770
Abstract:
The present invention is directed to a novel apparatus for âon-the-flyâ data correction and regeneration of a plurality of data read from and stored to a plurality of storage devices. A control circuit is provided for control of data flow to and from the storage devices. The control circuit establishes and maintains a relatively simple semaphore between itself and an interface circuit controlling a FIFO buffer. A mask register is provided as a type of programmable logic AND gate to assert a master ready signal when each of a selected plurality of the interface circuits, one interface circuit per FIFO buffer, indicates that its respective FIFO buffer is ready, either to output or input an entire block. When each is ready, routing and correction commences under control of the control circuit until an entire block has been processed. Each interface circuit includes an associated flip/flop having an output which provides an indication of the ready status.
System And Method For Policy Based Storage Provisioning And Management
US Patent:
6801992, Oct 5, 2004
Filed:
Feb 13, 2002
Appl. No.:
10/077482
Inventors:
Kumar Gajjar - San Jose CA

Assignee:
Candera, Inc. - Milpitas CA
International Classification:
G06F 1200
US Classification:
711173, 711112, 711153, 709215, 718104
Abstract:
A storage provisioning policy is created by specifying storage heuristics for storage attributes using storage heuristic metadata. Storage attributes characterize a storage device and storage heuristic metadata describe how to specify a storage heuristic. Using the storage heuristic metadata, storage heuristics are defined to express a rule or constraint as a function of a storage attribute. In addition, the storage provisioning policy may also specify mapping rules for exporting the storage to a consumer of the storage, such as the server or server cluster.
Auto Regression Test For Network-Based Storage Virtualization System
US Patent:
7032136, Apr 18, 2006
Filed:
Sep 9, 2002
Appl. No.:
10/238932
Inventors:

Assignee:
Network Appliance, Inc. - Sunnyvale CA
International Classification:
G06F 11/00
US Classification:
714 43, 714 42
Abstract:
An apparatus and method for testing a network-based storage virtualization system. A tester is connected to a host side of a storage virtualization system. The tester provides test scripts to the storage virtualization system to test I/O and other operations. A separate link, independent of said storage virtualization system, is provided to a storage side of said storage virtualization system to allow verification of the correct translation from virtual to physical independent of the data path used by the virtualization system. Thus, the tester verifies, over the separate link, the physical configuration of VLUNs and data written to the VLUNs by the tester on storage devices.
Failover Processing In A Storage System
US Patent:
7039827, May 2, 2006
Filed:
Feb 13, 2002
Appl. No.:
10/076906
Inventors:

Assignee:
Network Appliance, Inc. - Sunnyvale CA
International Classification:
G06F 11/00
US Classification:
714 4, 714 43
Abstract:
Failover processing in storage server system utilizes policies for managing fault tolerance (FT) and high availability (HA) configurations. The approach encapsulates the knowledge of failover recovery between components within a storage server and between storage server systems. This knowledge includes information about what components are participating in a Failover Set, how they are configured for failover, what is the Fail-Stop policy, and what are the steps to perform when “failing-over” a component.
System And Method For Policy Based Storage Provisioning And Management

International Classification:

US Classification:
711154, 711147, 711112, 709214
Abstract:
A storage provisioning policy is created by specifying storage heuristics for storage attributes using storage heuristic metadata. Storage attributes characterize a storage device and storage heuristic metadata describe how to specify a storage heuristic. Using the storage heuristic metadata, storage heuristics are defined to express a rule or constraint as a function of a storage attribute. In addition, the storage provisioning policy may also specify mapping rules for exporting the storage to a consumer of the storage, such as the server or server cluster.
Method For Device Security In A Heterogeneous Storage Network Environment

Assignee:
Network Appliance, Inc. - Sunnyvale CA
International Classification:
H04L 9/00
US Classification:
726 1, 711163
Abstract:
An automated, policy-based system and method provides information security at various levels in the network, including at the baseline inventory, device, network frame, and command level. This approach improves over the conventional distributed security model by centralizing security in one multi-level management structure. Embodiments of the present invention may also provide a scheme for mapping vendor-unique opcodes to access rights.

G06F 12/00
US Classification:
709225
Abstract:
A storage virtualization controller for transferring data between a host and a storage device at a wire-speed data transfer rate. A downstream processing element adapted for connection to the storage device is configurable coupled to an upstream processing element adapted for connection to the host. A central processing element coupled to the upstream processing element grants permission to the upstream processing element to transfer the data at the wire-speed rate without further involvement by the central processing element.

US Classification:
709215, 709212, 711114, 711202
Abstract:
In a storage server on a storage area network, a media unit manager manages disk space in a manner transparent to the host computers. The media unit manager uses media units corresponding to the physical storage devices on the storage area network to build higher-level media units. The higher level media units can have the attributes of being sliced, concatenated, mirrored, striped, etc. Thus, the host computers need not be aware of the specific physical storage devices themselves, reducing the management and reconfiguration burden on the host computers when storage devices are added to or removed from the storage area network.
