Abstract: Disclosed are apparatuses and corresponding and/or associated methodologies for sustainable (refillable) candles. This technology relates to refurbishing a used candle jar or container, so that its depleted wick and/or wax components are exchanged for replacement wick and wax components, so that the candle jar can be reused instead of being thrown out. An end of the wick is associated with an anchor or insert (such as a centering or positioning heat-resistant disc, removable silicone (or other materials) tray, or other). The replacement wick is physically held straight up and held in place by replacement scented wax beads, pellets, or the like poured into the jar. Burning of the wick melts and consumes the wax as it goes. After the wax and wick are exhausted, the insert and any remaining wax and other debris are removed from the jar in preparation for another refurbishment cycle. The insert is cleaned as needed for reuse with a new replacement wick.

Abstract: A method for operating a storage controller to write to a group of multi-actuator disk drives includes receiving a data stream, performing RAID mapping to a preselected RAID level, organizing the data stream into at least one data stream, creating at least one parity data stream, organizing each data stream and parity data stream into blocks of data, dividing each data stream and each parity data stream into groups of blocks of data assigned to a logical unit representing a drive and an actuator, blocks of data from a data stream and parity stream assigned to a different drive, sequential groups of blocks of data assigned substantially equally to logical units representing actuators in each drive, providing each group of blocks of data to a target port associated with the drive to which it has been assigned, and sending each group of blocks of data from the target port.

Abstract: A method for writing data to a dual-actuator disk drive includes providing a multi-actuator disk drive having a first actuator communicating with first disk platters and a second actuator communicating with second disk platters, receiving in a storage controller coupled to the disk drive a data stream including groups of blocks of data to be written to the multi-actuator disk drive, alternately distributing from a disk controller in the disk drive sequential ones of the groups of blocks of data from the data stream to the first actuator and the second actuator as defined by commands from the storage controller, and simultaneously writing from the first actuator to the at least one first disk platter ones of the groups of blocks of data routed to the first actuator and writing from the second actuator to the at least one second disk platter ones of the groups of blocks of data routed to the second actuator.
