Transferring encoded data slices stored in flash memory of a storage network
A method for execution by a computing device of a storage network for transferring data includes detecting a shutdown associated with a local flash memory of the storage network. The method further includes determining whether to transfer encoded data slices stored in the local flash memory, wherein a plurality of data segments are dispersed storage error encoded in accordance with distributed data storage parameters to produce pluralities of sets of encoded data slices that include the encoded data slices. When determining to transfer, the method includes determining a group of encoded data slices stored in the local flash memory to transfer, determining at least one storage location for storage of the group of encoded data slices, transferring the group of encoded data slices to the at least one storage location and outputting a transfer message indicating that the group of encoded data slices has been transferred.
Zero copy message reception for applications
Zero copy message reception for guests is disclosed. For example, a host has a memory, a device with access to device memory addresses, a processor, and a supervisor. An application with access to application memory addresses (AMA) executes on the host. An AMA is mapped to a page table entry (PTE). The application shares access to a first page of memory addressed by the AMA with the device to store data received by the device for the first application, where the first page is mapped as a device memory address of the plurality of device memory addresses. The application later sends a request to disconnect from the device. The supervisor is configured to copy contents of the first page to a second page in the memory after receiving the request to disconnect, and then update the PTE to address the second page instead of the first page.
Parallel model deployment for artificial intelligence using a primary storage system
Example artificial intelligence systems and methods provide parallel storage of data to primary storage and notification to a model server supported by the primary storage. A primary storage system receives operations on a training data set from a model trainer and sends a model instance of a computational model to a model server. When a new data element is received by a data ingester, the model server is initiated to evaluate the new data element using the model instance while the primary storage system stores the new data element in parallel.
