    摘要： An object tiering system transfers or tiers data objects from a data store to a cloud store. The system includes a processor and a memory having stored instructions that, when executed by the processor, cause the processor to ingest a first plurality of data objects in the data store, map a second plurality of data objects having a common tiering date to a region, and upon reaching the common tiering date, transfer the region to the cloud store. In some embodiments, the mapping is done a priori when each data object is ingested or at a first time before the common tiering date. In some embodiments, the common tiering date is a second time for transferring the second plurality of data objects from the data store to the cloud store. In some embodiments, the first plurality of objects includes the second plurality of objects.

    摘要： Various embodiments set forth techniques for taking a snapshot of virtual memory of a virtual machine. One technique includes allocating, in a persistent memory, one or more blocks associated with a virtual memory; detecting a write request associated with a first portion of the virtual memory; in response to detecting the write request associated with the first portion, prioritizing the first portion; based on the prioritizing, copying the first portion into the one or more blocks in the persistent memory ahead of a second portion of the virtual memory; and after copying the first portion: applying the write request to the first portion; and copying the second portion into the one or more blocks in the persistent memory.

    摘要： Data analytics systems are described herein which may provide requests for file tiering to one or more file servers. The data analytics systems may receive metadata and/or event data from one or more file servers and may utilize the metadata and/or event data to select files for tiering. In some examples, files may be selected using a sliding window methodology. In some examples, files may be selected in part based on user behavior with the files in the file system. In some examples, file analytics systems may send requests to retry tiering operations which failed. The retry requests may be sent in a manner that is based on the error which caused the failure.
