  • Synchronous block level replication across availability zones
    Patent number: 11841734
    Abstract: A replicated block storage service provides durable and high performance network-attached storage replicated in two or more zones of a single region, and remains available despite a single zone failure. A probe file is generated to determine a health state of a replicated disk. When a disk is degraded, a lease is created indicating which replica is trusted and providing visibility to backend jobs to facilitate reconciliation of data between the first replica and the second replica. Moreover, degraded file markers are generated for use by the backend jobs in quickly identifying the data to be copied.

  • Partitioning of contended synchronization objects
    Patent number: 8103638
    Abstract: Methods, systems, and computer-readable media are disclosed for partitioning contended synchronization objects. A particular method determines a contention-free value of a performance metric associated with a synchronization object of a data structure. A contended value of the performance metric is measured, and the synchronization object is partitioned when the contended value of the performance metric exceeds a multiple of the contention-free value of the performance metric.
