| 20090037766 | Storage System With Cascaded Copy targeting and Enhanced Integrity - A storage controller includes an interface to host computer apparatus and an interface to a plurality of controlled storage apparatus. The storage controller comprises a host write component operable to send a request to write a data object to a source data image at one of said plurality of controlled storage apparatus; a copy component operable in response to a metadata state to control copying of said data object to a target data image in a delimited sequence of data images in a cascade at said plurality of controlled storage apparatus and a fill-in component operable in response to detection of an offline condition of a disk containing said target data image to control substitution of a fill-in disk in place of said disk containing said target data image. | 02-05-2009 |
| 20090144499 | Preemptive write-inhibition for thin provisioning storage subsystem - Write requests from host computers are processed in relation to a thin provisioning storage subsystem. A write request is received from a host computer. The write request identifies a first virtual disk that has been previously assigned to the host computer. It is determined whether the first virtual disk has to be allocated additional physical storage locations of the thin provisioning storage subsystem for storing data associated with the write request. In response to determining that the virtual disk has to be allocated additional physical storage locations, the following is performed. First, a quantity of free space remaining unallocated within physical storage locations of the thin provisioning storage subsystem is determined. Second, where the quantity of free space remaining unallocated within the physical storage locations satisfies a policy threshold associated with a second virtual disk, the second virtual disk is write-inhibited. The first and second virtual disks can be different. | 06-04-2009 |

| 20080215838 | Providing Storage Control in a Network of Storage Controllers - An apparatus for providing storage control in a network of storage controllers is disclosed. The apparatus includes an owner storage controller; an I/O performing component, an ownership assignment component, a lock manager and a messaging component. The ownership assignment component assigns ownership of metadata for data to an owner storage controller. The lock manager controls the locking of metadata during I/O. The messaging component passes messages among storage controllers to request metadata state, to grant locks, to request release of locks, and to signal lock release. The I/O is performed on data whose metadata is owned by an owner storage controller, subject to compliance with metadata lock protocols controlled by the owner storage controller, and any copy of the data held from time to time is maintained in a coherency relation with the data. | 09-04-2008 |

| 20120131239 | DYNAMIC RESOURCE ALLOCATION FOR DISTRIBUTED CLUSTER-STORAGE NETWORK - Various embodiments for operating a distributed cluster storage network having a host computer system and a storage subsystem are provided. In one embodiment, by way of example only, at a first of a plurality of storage control nodes a request is received to write data to storage from the host computer system. The data is forwarded by a forwarding layer at the first of the plurality of storage control nodes to a second of the plurality of storage control nodes. Buffer resource are allocated for the data to be written to the storage by a buffer control component at each of the plurality of storage control nodes. The constrained status indicator of the buffer resource is communicated to the forwarding layer. Additional system and computer program product embodiments are disclosed and provide related advantages. | 05-24-2012 |

| 20090019947 | Correcting for Two-Phase Flow in a Digital Flowmeter - A flowmeter is disclosed. The flowmeter includes a vibratable conduit, and a driver connected to the conduit that is operable to impart motion to the conduit. A sensor is connected to the conduit and is operable to sense the motion of the conduit and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to detect a single-phase flow condition and process the sensor signal using a first process during the single-phase flow condition to generate a validated mass-flow measurement. The controller is also operable to detect a two-phase flow condition and process the sensor signal using a second process during the two-phase flow condition to generate the validated mass-flow measurement. | 01-22-2009 |

| 20100111217 | METHOD AND SYSTEM FOR REDUCING PHASE DIFFERENCE AND DOPPLER EFFECTS IN DETECTION AND COMMUNICATION SYSTEMS - Disclosed is a detection or communication system and method. The detection or communication method and system includes a code generator for generating a set of N complementary Golay sequences, the code generator encodes a baseband signal with the complementary Golay sequences wherein the complementary Golay sequences have an ideal autocorrelation and the sum of cross-correlations of every Golay complementary sequence set is zero thereby reducing phase difference and Doppler effects. The detection or communication system and method also includes a modulator for modulating each of the N sets of encoded complementary Golay sequences onto separate frequencies and a transducer for transmitting the modulated N sets of encoded complementary Golay sequences, the transducer receiving the transmitted signal reflected from an object, a demodulator for demodulating the received signal into N sets of complementary baseband signals and a correlator for correlating the demodulated complementary baseband signals, thereby generating a signal from the correlated baseband signals. | 05-06-2010 |
