  • Publication number: 20230022243
    Abstract: Snapshots are processed without holding all write operations while the snapshots are being activated. Rather than holding all write operations until snapshots are activated, write operations may be allowed to proceed. Snapshot write processing may be temporarily suspended while the snapshots are being activated, including snapshot metadata being updated, while write operations received while the snapshots are being activated are logged. After snapshots have been activated for all logical LSUs for which snapshots were instructed to be activated, the logging of write operations may be stopped, and the logged write entries processed to determine whether any of the logged write operations require updating snapshot information of any logical storage elements (LSEs) of the LSUs. While the logged write operations are being processed, any write operations received from a host for an LSE having a logged write operation may be held until the held operation, or all held operations are processed.

  • Patent number: 11561915
    Abstract: A host system may include a computational processing unit implemented using hardware and a hardware virtualizing and remote sharing (HVRS) server that virtualizes and shares the computational processing unit with other host systems, where the host system is directly connected to an internal fabric of a storage system. A storage system interface (SSI) of the host system may be directly connected to the internal fabric of the storage system and also directly connected to a same peripheral device interconnect as the CPU, the computational processing unit and/or other hardware resources of the host system. The SSI may communicate with storage resources of the storage system using remote direct memory access (RDMA) and zero-copy technologies. Such a host system may provide the storage capacity and data protection services of a storage system at relatively fast speeds e.g., comparable to non-volatile RAM on a host system configured for use as persistent memory.

  • Patent number: 11513939
    Abstract: Improved mechanisms and techniques for recording and aggregating trace information from multiple computing modules of a storage system may be provided. On a storage system having multiple computing modules, where each computing module has multiple processing cores, processing cores may record trace information for I/O operations in dedicated local memory—i.e., memory in the same computing module as the processing core that is dedicated to the computing module. One of the processing cores may be configured to aggregate trace information from across multiple computing modules into its dedicated local memory by accessing trace information from the dedicated local memories of the other computing modules in addition to its own. The aggregated information in one dedicated local memory then may be analyzed for functionality and/or performance and additional action taken based on the analysis.

  • Patent number: 11502853
    Abstract: A trust relationship may be established between a host system and a storage system. An asymmetric key pair including a private key unique to a host system and a public key may be generated. During provisioning of the host system to the storage system, the host system may send the public key to the storage system. The storage system may be configured to record the public key for the host system, for example, in a masking table that defines I/O connectivity for logical storage units between a host system and the storage system. The public key may be used later to validate the host system to the storage system. The private key may be stored on the host system and be unreadable, or may be encrypted with an unreadable encryption key stored on the host system.

  • Publication number: 20220345295
    Abstract: Decrypting data at a first storage system that has been encrypted at a second, separate, storage system includes the first storage system requesting a key that decrypts the data from the second storage system, the second storage system determining if the first storage system is authorized for the key, the second storage system providing the key to the first storage system in response to the first storage system being authorized, a host that is coupled to the first storage system obtaining the key from the first storage system, and the host using the key to decrypt and access the data at the first storage system. The host and the first storage system may provide failover functionality for a system that includes the second storage system. The host may obtain the key from the first storage system in response to a failure of the system that includes the second storage system.

  • Patent number: 11481138
    Abstract: Snapshots are created on replicated storage systems R1 and R2 in a manner resulting in identical snapshots being generated on R1 and R2. In response to an instruction to create a snapshot on a storage system (R1 and/or R2), command-phase write operations (CWOs) are held and data-phase write operations (DWOs) are completed on the storage system before the snapshot is created. Determining that DWOs includes querying processes, and using information, available on the storage system, by which a state of a write operation—e.g., whether the write operation is a DWO and when the DWO completes—may be determined. A CWO queue may be maintained on the storage system for tracking the status of CWOs. A DWO queue may be maintained on the storage system for tracking DWOs, to determine DWOs when the snapshot is created, and track their processing, including when they are completed.

  • Patent number: 11481147
    Abstract: Techniques for transmitting data may include: statically allocating a first buffer by a first entity; determining, by the second code entity, whether first data to be returned to the first entity fits into a data area of the first buffer; storing the first data in the data area of the first buffer responsive to determining the first data fits into the data area of the first buffer; and responsive to determining the first data does not fit into the data area of the first buffer, performing first processing by the second entity to store the first data in a dynamically allocated second buffer having a descriptor stored in the first buffer. The descriptor may include the address and size of the second buffer. The first and second entity may be code entities in the same system, or may be different systems that communicate using a remote direct memory access protocol.
