Abstract: Methods, non-transitory computer readable media, and computing devices that manages distributed snapshot for low latency storage includes accessing one or more snapshots from one or more solid state devices (SSD), wherein the obtained one or more snapshots are stored in a snapshot allocated capacity of the one or more SSD. A data transfer operation is initiated from a primary storage to a secondary storage using the accessed one or more snapshots. It is determined if the initiated data transfer operation is completed and when it is determined to be completed, the obtained one or more snapshots stored in the snapshot allocated capacity of the one or more SSD are deleted.

Abstract: Methods and systems for storing data at a storage device of a storage system are provided. The data is first temporarily stored at a first write cache and an input/output request for a persistence storage device used as a second write cache is generated, when an I/O request size including the received data has reached a threshold value. The data from the first cache is transferred to the persistence storage device and a recovery control block with a location of the data stored at the persistence storage device is updated. An entry is added to a linked list that is used to track valid data stored at the persistence storage device and then the data is transferred from the persistence storage device to the storage device of the storage system.

Abstract: A system and method for planning and configuring the components of a modular computing system is provided. In some embodiments, the method for planning an implementation of a modular computing system comprises presenting a user interface at a display device, the user interface including a plurality of user-selectable objects, each of the user-selectable objects representing a component of the modular computing system. A user selection is received via a user input device. The user selection is from among the user-selectable objects and specifies one of an enclosure, an existing component, and a future component of the modular computing system. A representation of the specified one of an enclosure, an existing component, and a future component is displayed at a display device. The user selection is verified with respect to an implementation guideline. An indicator of whether the user selection meets the implementation guideline is displayed at the display device.

Abstract: System and method for dynamic storage tiering are disclosed. A storage hot-spot in a first storage pool is detected. A first point-in-time copy of a virtual volume including the storage hot-spot is created in a second storage pool according to the detecting. Write requests directed to the virtual volume are redirected to the second storage pool. When decreased I/O activity directed to the storage hot-spot in the second storage pool is detected, the point-in-time copy in the second storage pool is reintegrated into at least one of a second point-in-time copy or the virtual volume.

In some embodiments, the method comprises determining, using a computing system, whether all components of a modular computing system have been received by a customer. Based on determining that not all the components of the modular computing system have been received by the customer, it is determined whether the modular computing system can be incrementally deployed. A customer instruction for incrementally deploying the modular computing system is provided at a display device. A communication link is established with a component of the modular computing system. Communications directed over the communication link are used to determine whether a customer correctly performed the provided customer instruction. In one such embodiment, the determining of whether the modular computing system can be incrementally deployed includes determining whether a minimum resource requirement is met.

Abstract: Storage systems configured for improved N-way connectivity among all of a plurality of storage controllers and all of a plurality of storage devices in the system. All controllers of the storage system are coupled through a switched fabric communication medium to all of the storage devices of the storage system. Thus, the back-end interface of each storage controller of the storage system is used for all communications with any of the storage devices as well as for any communications among the controllers to coordinate the N-way distribution of stored data in a declustered RAID storage environment. This use of the back-end channel for all storage controller to storage device N-way connectivity as well as controller to controller N-way connectivity eliminates the need for a dedicated inter-controller interface for such N-way connectivity and eliminates the over-utilization of a front-end (e.g., network) communication path for providing N-way connectivity in the storage system.

Abstract: A process for block-level tracking of a sequential data stream that is sub-divided into multiple parts, and stored, by a file system, within non-sequential storage blocks. The process creates block-level metadata as the sequential data stream is written to the storage blocks, wherein the metadata stores pointers to the non-sequential storage blocks used to store the multiple parts of the sequential data stream. This metadata can subsequently be used by a block-level controller to more efficiently read the sequential data stream back to the file system using read-ahead processes.
