Abstract: A clock output unit outputs a synchronous clock signal. A serial data receiving unit receives data representing an absolute position and an encoder sends data in synchronization with the synchronous clock signal. A position conversion unit converts the received absolute position into a current position. The position conversion unit calculates a difference between a last received absolute position and an absolute position received immediately before the last received absolute position. The position conversion unit obtains the latest current position by adding the difference and a current position that was calculated immediately before the latest current position. If the absolute value of the calculated difference is greater than a threshold value, the position conversion unit determines that the last received absolute position has an error.

Abstract: A memory subsystem can test a memory device in situ, testing the performance of parameters of operation the device in the system it is built into during production. Thus, the system can detect the specific values that will work for one or more operating parameters for the memory device in actual runtime. A test component embedded in the memory subsystem can perform a stress test and identify specific bits or lines of memory that experience failure under one or more stresses. The system can then map out the failed bits or lines to prevent the bits/lines from being used in runtime of the system.

Abstract: A storage system comprises a first storage device having a first plurality of hard disk drives and a first controller. The first controller stores data in the first plurality of hard disk drives by stripes. Each stripe includes M data and N parity data allocated to M+N hard disk drives of the first plurality of hard disk drives. A first hard disk drive includes data or parity data of both a first stripe of the stripes and a second stripe of the stripes, while a second hard disk drive includes data or parity data of only one of the first stripe or the second stripe. During data recovery involving failure of one of the first plurality of hard disk drives, the data in the failed hard disk drive is recovered for each stripe by calculation using data and parity data in other hard disk drives for each stripe.

Abstract: A method, system and computer program product are disclosed for recovery in a virtualized environment using remote direct memory access (RDMA). In one embodiment, the method comprises operating a virtual computer system on a physical computer system, and the virtual system maintains in a memory area a record of a state of the virtual system. In this method, when defined error conditions occur on the virtual system, RDMA is used to pull the record of the state of the virtual system from that memory area onto a standby computer. This record on the standby computer is used to re-initialize the virtual computer. Embodiments of the invention provide methods that provide a very fast recovery from a virtual machine fault or error, while requiring much fewer resources than standard approaches. In embodiments of the invention, one spare real computer system can be used for backing up several virtual systems.

Abstract: In a computing device supporting a failover in an event stream processing (ESP) system, an event block object is received. A first status of the computing device as active or standby is determined. When the first status is active, a second status of the computing device as newly active or not newly active is determined. Newly active is determined when the computing device is switched from a standby to an active status. When the second status is newly active, a last published event block object identifier that uniquely identifies a last published event block object is determined. A next event block object is selected from a non-transitory computer-readable medium accessible by the computing device. The next event block object has an event block object identifier that is greater than the determined last published event block object identifier. The selected next event block object is published to an out-messaging network device.

Abstract: Techniques for meta-directory control and evaluation of events are provided. Disparate events from heterogeneous processing environments are collected as the events are produced by resources within the processing environments. The events are filtered and organized into taxonomies. Next the filtered and organized events are assigned to nodes of a Meta directory, each node defining a relationship between two or more of the resources and policy is applied. Finally, additional policy is evaluated in view of the events and their node assignments with other events, and one or more automated actions are then taken.
