A computer system stores metadata that is used to identify physical memory devices that store randomly-accessible data for memory of the computer system. In one approach, access to memory in an address space is maintained by an operating system of the computer system. Stored metadata associates a first address range of the address space with a first memory device, and a second address range of the address space with a second memory device. The operating system manages processes running on the computer system by accessing the stored metadata. This management includes allocating memory based on the stored metadata so that data for a first process is stored in the first memory device, and data for a second process is stored in the second memory device.

Preventing applications from overconsuming shared storage resources, including: identifying one or more sub-regions of data stored on a storage device that are associated with an application of a known application type; compiling information describing the application's utilization of a storage system; determining that a storage system objective has not been met; and initiating, based on the information describing the application's utilization of the storage system, remediation actions.

An edge accelerator card has a first interface, a second interface, a memory and a processor. The first interface is to couple to a server. The second interface is to couple to a storage system. The processor is to handle communication between the server and the storage system through the first interface and the second interface. The processor is to perform at least one task as directed by the storage system, using the memory and communication through at least the second interface.

A device may include a buffer memory to buffer frames received or to be transmitted via a plurality of ports of the device. The device may include at least one frame processor to process frames. The device may include a buffer manager to store a frame in the buffer memory. The buffer manager may allocate at least one buffer control block (BCB) to the frame based on storing the frame in the buffer memory. The buffer manager may allocate a frame control block (FCB) to the frame. The FCB may include information that identifies the at least one BCB. The buffer manager may perform one or more queueing operations in association with processing of the frame by the at least one frame processor. The one or more queuing operations may be performed using information associated with the FCB.

Systems, devices, and methods are disclosed herein for containerized scalable storage applications. Methods may include instantiating an application instance based on a plurality of application instance parameters, the application instance being configured to utilize a plurality of storage volumes implemented in a storage cluster. Methods may also include enumerating a plurality of unattached storage volumes included in the cluster associated with the application instance, the plurality of unattached storage volumes having a plurality of underlying physical storage devices, and the plurality of unattached storage volumes being identified based on a plurality of application instance parameters. The methods may further include attaching at least some of the plurality of unattached storage volumes to the application instance, wherein the attaching enables the application instance to access data stored in the attached storage volumes.

Methods and systems provided herein involve extracting an input/output (I/O) operation from a packet received over an I/O pipeline, the I/O operation comprising either a read request to read data from at least one storage device or a write request to write data to the at least one storage device; determining that an address associated with the I/O operation exists in a lookup table that is provided for thin provisioning of the at least one storage device; performing one or more RAID calculations associated with the at least one storage device based on the address and the I/O operation; and accessing the at least one storage device to perform the I/O operation based on the one or more RAID calculations; and second processing component configured to carry out a second set of operations that occur when the address associated with the I/O operation does not exist in the lookup table.

A data management method includes receiving, by a management server, a first request, determining, based on an identifier of a first user in the first request, whether a shadow tenant bucket associated with the identifier of the first user exists, and if the shadow tenant bucket associated with the identifier of the first user exists, storing, in the shadow tenant bucket associated with the identifier of the first user, an acceleration engine image (AEI) that the first user requests to register, where a shadow tenant bucket is used to store an AEI of a specified user, and each shadow tenant bucket is in a one-to-one correspondence with a user.

Exemplary surveillance system is provided having a plurality of data generating devices, and nodes for data handling of the data streams generated from the data generating devices. The system may be configured to fragment the data streams and store the fragments among the plurality of nodes of the system. The system may be configured to redundantly transmit data through the nodes so the fragmented data stream arrive at the desired location for storage. The data transmission may permit redirection or retransmission based on node or data transmission failure.

Nodes in a storage system can autonomously ingest I/O requests and flush data to storage. First and second nodes determine a sequence separator, the sequence separator corresponding to an entry in a page descriptor ring that separates two flushing work sets (FWS). The first node receives an input/output (I/O) request and allocates a sequence identification (ID) number to the I/O request. The first node determines a FWS for the I/O request based on the sequence separator and the sequence ID number, and commits the I/O request using the sequence ID number. The I/O request and the sequence ID number are sent to the second node.

Techniques for extending a storage system having a first pool involve adding, in response to a request, second storage devices, wherein the first pool is generated using first storage devices and based on a first standard. The first pool includes first stripes created using the first standard, and the number of the second storage devices equals a first stripe width associated with the first standard. Such techniques further involve creating a second pool using the second storage devices and based on a second standard, wherein a second stripe width associated with the second standard equals the first stripe width. Such techniques further involve creating second stripes in the second pool using the second storage devices and based on the second standard. Such techniques further involve storing data of at least one of the first stripes to a corresponding stripe of the second stripes according to a data shuffle rule.
