Abstract: Methods, systems, and computer program products for importing a workload from an external system into a virtualization system. A virtual disk (vDisk) is created based on analysis of the data layout of the workload. The vDisk is sharded into a plurality of non-overlapping shards. Independently executing shard controllers are assigned to the non-overlapping shards. On an ongoing basis, the plurality of shard controllers manage respective shards of the plurality of shards. I/O activity on at least some individual ones of the plurality of shard controllers is monitored on an ongoing basis. Two or more shard controllers can be merged into a single shard controller when the I/O activity on the two or more shard controllers is measured to be below a threshold. A single shard controller can be split into two or more shard controllers when I/O activity on the single shard controller is measured to be above a threshold.

Abstract: Various embodiments set forth techniques for maintaining replicas of a data set. The techniques include storing, by a first node, a first replica of the data set on the first node; storing, by a second node, a second replica of the data set on the second node; and performing, by the first node and based on first metadata associated with the first replica, a first data management activity on the first replica that changes a first format of the first replica so that the first format of the first replica is different from a second format of the second replica.

Abstract: One or more non-transitory computer-readable media can store program instructions that, when executed by one or more processors, cause the one or more processors to perform steps of organizing storage as a set of storage regions, each storage region having a fixed size; and for each storage region, storing a storage allocation structure of the storage region formatted in a first format selected from a format set including at least two formats, determining a change of an allocation feature of the storage region, based on the allocation feature of the storage region, selecting, from the format set, a second format of the storage allocation structure, and reformatting the storage allocation structure in the second format.
