A data management system comprises: a storage appliance configured to store a snapshot of a virtual machine; and one or more processors in communication with the storage appliance. The one or more processors are configured to perform operations including: identifying a plurality of shards of the virtual machine; requesting a snapshot of each of the plurality of shards; receiving the shards asynchronously; ordering the received snapshot shards sequentially into a results queue; and storing a single snapshot of the virtual machine based on the ordered snapshot shards. Operations may further include maintaining a flow control queue that limits the number of snapshot shards requested.

Asynchronous input and output for snapshots of virtual machines

A data management system having a storage appliance configured to store a snapshot of a virtual machine; and one or more processors in communication with the storage appliance. The one or more processors are configured to perform operations including: identifying a plurality of shards of the virtual machine; requesting a shard snapshot of each of the plurality of shards; receiving the shard snapshots asynchronously; ordering the received shard snapshots sequentially into a results queue; and storing a single snapshot of the virtual machine based on the ordered shard snapshots. The operations may further include maintaining a flow control queue that limits a number of the requested shard snapshots.

Pet feeder tilted table

A method for determining a retention time in a solid state device (SSD), comprising the steps of providing a plurality of write operations to a memory, determining a reference voltage for each of the write operations, determining a difference between (i) the reference voltage after each of the write operations and (ii) a target reference voltage and if the difference is above a predetermined value, generating a flag indicating an excessive retention has occurred.
