摘要： Provided are an interrupt on/off management apparatus and method for a multi-core processor having a plurality of central processing unit (CPU) cores. The interrupt on/off management apparatus manages the multi-core processor such that at least one of two or more CPU cores included in a target CPU set can execute an urgent interrupt. For example, the interrupt on/off management apparatus controls the movement of each CPU core from a critical section to a non-critical section such that at least one of the CPU cores is located in the non-critical section. The critical section may include an interrupt-disabled section or a kernel non-preemptible section, and the non-critical section may include an interrupt-enabled section or include both of the interrupt-enabled section and a kernel preemptible section.

摘要： A stripe reconstituting method in a storage system, a garbage collection method employing the stripe reconstituting method, and the storage system performing the stripe reconstituting method are provided. The stripe reconstituting method includes the operations of selecting a target stripe in which an imbalance between valid page ratios of memory blocks included in the target stripe exceeds an initially-set threshold value, from among stripes produced in a log-structured storage system; and reconstituting a stripe by regrouping the memory blocks included in the target stripe such that the imbalance between the valid page ratios of the memory blocks included in the target stripe is reduced.
