| 20080209136 | SYSTEM AND METHOD OF STORAGE SYSTEM ASSISTED I/O FENCING FOR SHARED STORAGE CONFIGURATION - Systems and methods for improved I/O fencing for shared storage in a clustered or grid computing environment. I/O fencing is performed with aid from the storage system and an I/O fencing management client process. The client process detects changes in the operational status of any of the clustered computing nodes. Upon sensing a change from a functional state to a dysfunctional state, the management client process effectuates reconfiguration of the storage system to disallow potentially destructive access by the dysfunctional node to the shared storage volumes. Upon sensing resumption of a functional status for the dysfunctional node, the client effectuates reconfiguration of the storage system to again allow desired access to the shared storage volumes by the now functional node. The client and storage system may share access to a database maintained by the client indicating the shared volumes a node may access and the initiators associated with each node. | 08-28-2008 |
| 20080229045 | STORAGE SYSTEM PROVISIONING ARCHITECTURE - In some embodiments, a storage controller comprises a first input/output port that provides an interface to a host computer, a second input/output port that provides an interface a storage device, a processor that receives input/output requests generated by the host computer and, in response to the input/output requests, generates and transmits input/output requests to the storage device, and a memory module communicatively connected to the processor. The memory module comprises logic instructions stored in a computer-readable medium which, when executed by the processor, configure the processor to receive, from the host computer, a write input/output request that identifies a logical volume; compare an amount of storage space available in the logical volume with an amount of storage space required to complete the write operation, and allocate additional storage space to the logical volume if the amount of storage space available in the logical volume is insufficient to complete the write operation. Other embodiments may be described. | 09-18-2008 |
| 20090285098 | SYSTEMS AND METHODS FOR LOAD BALANCING STORAGE SYSTEM REQUESTS IN A MULTI-PATH ENVIRONMENT BASED ON TRANSFER SPEED OF THE MULTIPLE PATHS - Methods and systems for distributing I/O requests from a computer system to a storage system over multiple paths having non-homogeneous transfer speeds. A large I/O request is partitioned into a plurality of smaller I/O operations between a computer system and a storage system. The I/O operations are distributed over a plurality of communication paths coupling the computer system and the storage system. The distribution attempts to balance the load over the multiple paths based on the transfer speed of each path. In one embodiment, operations are distributed only to the highest speed paths presently operable. In another embodiment, an estimated completion time for an operation is determined for each path and a path with the lowest estimated completion time is selected to transfer the next operation. | 11-19-2009 |
| 20100199116 | MULTIPATH POWER MANAGEMENT - Disclosed is a method of controlling power. Multiple paths via multiple I/O ports couple a server to a storage array. When I/O loads are low, it is determined if an I/O port may be deactivated and placed in a power saving mode. An I/O port may not be deactivated if deactivating that I/O port will affect a high-availability requirement or a performance requirement. Requests are stopped from being sent to an I/O port to be deactivated. When the port to be deactivated becomes idle, the I/O port is placed in a power saving mode. When I/O loads increase to a point where it is necessary to reactivate the I/O port, the I/O port is activated. | 08-05-2010 |
| 20100281101 | UNIFIED SUPPORT FOR WEB BASED ENTERPRISE MANAGEMENT ("WBEM") SOLUTIONS - Methods and systems for support a unified Web Based Enterprise Management (“WBEM”) solution is provided. A first processing element for generating first HTTP content data is provided such that a response to a non-Common Information Model (“CIM”) request is based on the first HTTP content data. A second processing element for generating second HTTP content data is also provided such that another response to a CIM request is based on the second HTTP content data. At least one of the first processing element and the second processing element is accessible directly only from within the system to unify access to the two elements. | 11-04-2010 |
| 20120124319 | METHODS AND STRUCTURE FOR TUNING STORAGE SYSTEM PERFORMANCE BASED ON DETECTED PATTERNS OF BLOCK LEVEL USAGE - Methods and structure within a storage system for tuning performance of the storage system based on monitored block level access within the storage system. Block level access, either in cache memory or on the storage devices of the storage system, is monitored to detect patterns of access and/or data that correspond to an identified host system program. Based on the identified host system program, a profile of desired storage device configuration information is selected by the storage system. The profile comprises information identifying optimal configuration of a logical volume used by the corresponding host system program. Reconfiguration options are identified from the profile information and used either to automatically reconfigure the logical volume or are presented to a user to permit the user to select desired options from the reconfiguration options. | 05-17-2012 |
| 20120192006 | METHODS AND SYSTEMS FOR IMPROVED STORAGE REPLICATION MANAGEMENT AND SERVICE CONTINUANCE IN A COMPUTING ENTERPRISE - Systems and methods for management of replicated storage. Features and aspects hereof provide management of data replication among a plurality of storage systems in a manner substantially transparent to host systems attached to the storage systems. The storage systems are coupled to one another through a replication link. One storage systems is designated the primary storage system and all others are designated secondary storage systems. A common logical volume is defined with a common logical volume device identifier used by all of the replicating storage systems of a replication group and their respective attached host systems. The primary storage system processes I/O requests directed to the logical volume by accessing its physical storage volume and forwarding the request to be replicated to all secondary storage systems over the replication link. Secondary storage systems process I/O requests by shipping them over the replication link to the primary storage system for processing. | 07-26-2012 |
| 20140129771 | Multiple Instances of Mapping Configurations in a Storage System or Storage Appliance - The present invention is directed to a method and software for managing the host-to-volume mappings of a SAN storage system. The host-to-volume mappings of the SAN storage system are represented in mapping configuration components. The active mapping configuration component represents the current host-to-volume mapping for the SAN storage system. Only one mapping configuration component is active at a time. The host-to-volume mappings of the SAN storage system are changed by deactivating the active mapping configuration component and activating an inactive mapping configuration component that represents a different mapping configuration, effecting a repartition, repurpose, disaster recovery, or other business activity. This can be a scheduled task or performed in an on-demand manner. The mapping configuration components are managed and controlled through the management component of the SAN storage system. | 05-08-2014 |
