Abstract: A method and means in which data and parity blocks forming parity groups  together with  spare  blocks  are distributed over array block locations according to at least one combinatorial design, each group having N data and P parity blocks.  The  combinatorial  designs  yield uniform or balanced loading thereby minimizing the number of accesses to reconstruct missing data and parity blocks and  their  copyback  into  spare  block  locations,  and, minimize the number of accesses to the reconstructed data referenced subsequent to its copyback. Distributions of the spare block capacity of one or two DASDs are shown over single and multiple arrays and shared among multiple arrays. Parity block distribution although ancillary to spare distribution enhances throughput and reduces the number of accesses for rebuild etc.

Granted: 2000-09-19
Abstract: A voltage controlled oscillator apparatus for generating a desired frequency, set by a tuning voltage, toward modulating a transmission signal on the desired frequency. The voltage controlled oscillator apparatus includes an oscillator transistor the base of which is RF live so as to destabilize the transistor such that it oscillates. The oscillator transmitter emitter is operably connected through a capacitor to a tank circuit, which stores RF energy at the desired frequency, based on the tuning voltage, to set the oscillator transistor frequency. The inherent collector-base junction capacitance serves to provide voltage variable capacitance resulting in the generation of a carrier signal. The oscillator transistor collector is electrically connected to an amplifier transistor's emitter, such that the amplifier transistor and oscillator transistor are in cascode configuration.      The amplifier transistor amplifies the transmission signal input at its base and presents a signal output on its collector. whereby the need for a varactor external to the tank circuit is alleviated and the transmission signal is amplified and modulated on the carrier signal by the amplifier transistor due the interconnection between the oscillator and amplifier transistors in a manner which effectively isolates the transmission signal from the oscillator transistor and tank circuit.
