| 20090144755 | RETRIEVING DIAGNOSTICS INFORMATION IN AN N-WAY CLUSTERED RAID SUBSYSTEM - A method and system for reading exception data by a storage server from a storage controller. An exception event is detected at the storage server. The storage server registers with the controller, such that only one storage server can read the exception data at a time. If the storage server is registered with the controller, the storage server reads the exception data. If the storage server does not successfully register with the controller, the controller keeps track of which storage servers have not read the exception data, to ensure that all storage servers can read the data. | 06-04-2009 |
| 20090276566 | CREATING LOGICAL DISK DRIVES FOR RAID SUBSYSTEMS - A computer storage system includes multiple disk trays, each disk tray holding two or more physical disks. The disks on a single tray are virtualized into a single logical disk. The single logical disk reports to the RAID (redundant array of inexpensive disks) subsystem, creating the impression that there is one large capacity disk. In one implementation, each disk in the tray is allocated to a different RAID group. By allocating the disks in a tray to different RAID groups, if the tray is removed, only a portion of several different RAID groups are removed. This arrangement permits a simple reconstruction of the RAID groups if a disk tray is removed from the system. | 11-05-2009 |

| 20090267565 | METHOD AND SYSTEM FOR CELL EQUALIZATION WITH CHARGING SOURCES AND SHUNT REGULATORS - A system and method for charging a rechargeable, or secondary, battery including a series string of cells, includes a topology of charging sources that selectively provides charging current to cells that need to be charged, but avoids overcharging cells that are already charged above a predetermined voltage threshold. Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and by-passes battery cells that are fully charged or become fully charged. | 10-29-2009 |
| 20090309544 | METHOD AND SYSTEM FOR CELL EQUALIZATION WITH SWITCHED CHARGING SOURCES - A system and method for charging a rechargeable, or secondary, battery including a series string of cells, includes a topology of charging sources that selectively provides charging current to cells that need to be charged, but avoids overcharging cells that are already charged above a predetermined voltage threshold. Based on individual cell voltage measurements, the charging current is controlled in a manner to direct charging current to the battery cell(s) needing charge until these cells are fully charged, and by-passes battery cells that are fully charged or become fully charged. | 12-17-2009 |

| 20100232288 | Takeover of a Failed Node of a Cluster Storage System on a Per Aggregate Basis - A cluster comprises a plurality of nodes that access a shared storage, each node having two or more partner nodes. A primary node may own a plurality of aggregate sub-sets in the shared storage. Upon failure of the primary node, each partner node may take over ownership of an aggregate sub-set according to an aggregate failover data structure (AFDS). The AFDS may specify, an ordered data structure of two or more partner nodes to take over each aggregate sub-set, the ordered data structure comprising at least a first-ordered partner node assigned to take over the aggregate sub-set upon failure of the primary node and a second-ordered partner node assigned to take over the aggregate sub-set upon failure of the primary node and the first-ordered partner node. The additional workload of the failed primary node is distributed among two or more partner nodes and protection for multiple node failures is provided. | 09-16-2010 |
