Methods and systems for managing storage of data in a distributed system are disclosed. To manage storage of data in a distributed system, a data processing system may include a network interface controller (NIC). The network interface controller may present emulated storages that may be used for data storage. The emulated storage devices may utilize storage resources of storage devices. Overtime, the data stored in various data storages may be migrated between the data storages. To migrate the data, the NIC may manage the migration process. To do so, the NIC may obtain various access requests (e.g., writes, reads) and process them in a manner that allows for the migration to be transparent. By doing so, migrations that are transparent to compute resources of data processing systems may be completed.

Methods and systems for managing data access based threats are disclosed. To manage the data access based threats, a data processing system may include a network interface controller (NIC). The network interface controller may present emulated storages that may be used for data storage. The emulated storage devices may utilize storage resources of storage devices. The NIC may actively screen for access patterns in use of the emulated storage devices that indicate compute complexes may be compromised. When doing so, the processing may be done locally on the NIC.

Methods and systems for managing storage of data in a distributed system are disclosed. To manage storage of data in a distributed system, a data processing system may include a network interface controller (NIC). The network interface controller may present emulated storages that may be used for data storage. The emulated storage devices may utilize storage resources of storage devices. The storage devices may be remote to the NIC. To reduce communication bandwidth and/or use of resources of the storage devices, the NIC and/or NICs of other data processing systems may implemented a distributed cache for data stored in the storage devices. The NICs may implement a method of managing the distributed cache to maintain synchronization between the distributed cache and the data stored in the storage devices.

Methods and systems for managing storage of data in a distributed system is disclosed. To manage storage of data in a distributed system, a data processing system may include a network interface controller (NIC). The NIC may present emulated storages that may be used for data storage. The emulated storage devices may utilize storage resources of storage devices. The NIC and the storage devices may implement a distributed deduplication process. The NIC may segment data into chunks and obtain fingerprints of the chunks. The fingerprints may be provided to the storage which may check the fingerprints against fingerprints of already stored chunks. The storage may request the chunks corresponding to the fingerprints that did not match any fingerprints of the already stored chunks. The NIC may provide only those requested chunks to the storage before discarding all of the chunks.

A host can include a programmable network interface card (NIC) or 'Smart NIC' which accesses host-local drives hidden from a host processor. One configuration can include a switch with a one logical partition including the NIC as a root complex (RC) and the local drives as end points (EPs), and with another logical partition including the host processor as an RC and the NIC as an EP. A second configuration can include the NIC and switch directly connected to the host processor with an access control component (ACC) configured on switch ports connected to the local drives. A third configuration can include the NIC and local drives directly connected to the host processor with the ACC configured on host processor ports connected to the local drives. The NIC can use a multi-layer driver to communicate with the ACC and local drives hidden behind the ACC.

Techniques for providing access of host-local storage to a programmable network interface component while preventing direct host CPU access

Traditionally, servers are interconnected inside a data center using regular network cards. It is desired that high-available network-attached storage arrays have the feature of non-disruptive upgrade (NDU) for software and firmware, while one or more applications are still running IO. With the emergence of SmartNICs, there are many functions available now to SmartNIC that may enhance server and entire solution capabilities. Since SmartNIC is a new emerging technology, there are no adequate solutions currently for NDU while running I/O. The present patent document discloses embodiments for upgrading the SmartNIC software without disruption to the host applications. A shared namespace may be implemented inside an emulated NVMe/PCIe device, such as a data processing unit (DPU) or infrastructure processing unit (IPU), such that multiple instances may be enabled to run both old and new target emulation SPDK-based software together using multiple paths to achieve SmartNIC storage NDU.

Methods and systems for managing storage of data in a distributed system are disclosed. To manage storage of data in a distributed system, a data processing system may include a network interface controller (NIC). The NIC may present emulated storages that may be used for data storage. The emulated storage devices may be implemented with a storage pipeline that uses any number of storage devices that may be local or remote to the data processing system. The computing resources of the data processing system may view the emulated storage as a local device. The NIC may use its storage pipeline to service its own storage needs. By doing so, the NIC may improve the likelihood that its hosted applications have sufficient storage service access.
