METHOD TO PROVIDE SLA BASED ACCESS TO CLOUD DATA IN BACKUP SERVERS WITH MULTI CLOUD STORAGE
The disclosure provides a system, computer readable medium, and computer-implemented method for managing data access. The method includes obtaining a data access request from a requestor for client data redundantly stored in at least two storage providers that are unknown to the requestor; identifying a service level objective for servicing the data access request; ranking the at least two storage providers based on the service level objective to identify one of the at least two storage providers to service the data access request; and providing the requestor with access to a copy of the client data using the one of the at least two storage providers.
System and Method for Self-Encrypting Drive Reversion During Re-initialization of a Storage Array
A method, computer program product, and computing system for receiving a re-initialization operation request for a storage array, the storage array including a plurality of self-encrypting drives. A reversion state may be determined for each self-encrypting drive of the plurality of self-encrypting drives. In response to determining that at least one self-encrypting drive is in an unreverted state, at least one predefined reversion key for reverting the at least one self-encrypting drive from a predefined area of the storage array may be accessed. Each self-encrypting drive of the plurality of self-encrypting drives in the unreverted state may be reverted to a reverted state using the at least one predefined reversion key.
Distributed storage system for long term data storage
A distributed storage system for the long-term storage of data objects that is implemented utilizing one or more distinct storage sites that may be comprised of system controllers and object storage systems that act in concert to embody a single distributed storage system. A system may include a one or more types and/or instances of object storage systems. A system may include object storage systems that are powered on for a limited time as required to complete queued data operations. A system may further include system controllers associated with logical and/or physical sites that coordinate object, user, device, and system management functionally.
Copy-on-write systems and methods
Described methods and systems for copying a source volume to a target volume that include a combination of concurrent copying and a copy-on-write (COW) technique that improves the reliability of the backup process and requires fewer resources during a given backup instance than the processes of the prior art.
FILE STORAGE SYSTEM AND MANAGEMENT INFORMATION FILE RECOVERY METHOD
In order to quickly recover a management information file, an Edge file storage stores user files and a management information file that manages management states of the user files in the Edge file storage. The Edge file storage manages operation logs indicating operation contents concerning user files accepted by nodes in association with the respective nodes. The Edge file storage extracts operation logs for a user file associated with a targeted management information file as a management information file stored in a failed node from the operation logs corresponding to the nodes. The Edge file storage aggregates operation logs that are extracted from the operation logs corresponding to the nodes and are used for the user file associated with the targeted management information file. The Edge file storage recovers the targeted management information file based on the aggregated operation log.
Distributed storage resource reservation for replication, disaster recovery and data protection across multiple sites
A method includes: receiving, at a cluster controller of a first cluster, a request for pairing a first datastore of the first cluster to a second datastore of a second cluster, wherein each of the first cluster and the second cluster includes a plurality of datastores; determining whether the first datastore is available for pairing; in response to determining that the first datastore is available for pairing, generating an entry in a mapping table indicating that the first datastore is paired with the second datastore; receiving information associated with the second datastore; and in response to receiving the information, storing the information in the first datastore. The second cluster performs similar operations as those performed by the first cluster to achieve a bidirectional reservation between the first cluster and the second cluster.
CONTINUOUS DATA PROTECTION IN CLOUD USING STREAMS
One example method includes performing a recovery operation. A recovery operation is performed using streams rather than volumes in the cloud and without using compute instances or servers for do data or undo data. Do data is written to a do stream. Occasionally, a compute instance power on reads data from the do stream. After reading the data, chunks are read from cloud storage and updated. Data overwritten in the chunks are saved to an undo stream. A snapshot of the updated chunks and the associated undo stream is stored in the cloud storage.
MEMORY CONTROLLER AND MEMORY SYSTEM INCLUDING THE SAME
A memory system may include a memory device including a plurality of memory blocks, a buffer memory device, and a memory controller. The buffer memory device includes a read buffer configured to store the data read from the memory device and a keep buffer configured to store part of the read data. The memory controller operates to identify keeping data among data stored in the read buffer according to a number of error bits in the keeping data when it was read from the memory device, store the keeping data in the keep buffer, and remove the keeping data from the read buffer. The memory controller may store the keeping data in any one of the plurality of memory blocks based on information related to the keeping data.
Peripheral device for configuring compute instances at client-selected servers
A peripheral device includes one or more processors and a memory storing program instructions that when executed implement virtualization offloading components of a virtualized computing service, including a storage manager. The offloading components establish network connectivity with a control plane of the service. Based on detecting that a hardware server, in a separate enclosure, has been linked to the peripheral device, the hardware server is presented as a virtualization host of the service. The offloading components initiate compute instance configuration operations at the server in response to commands issued to the control plane, including at least one configuration operation initiated by the storage manager to enable access to a logical storage device from a compute instance.
METHOD FOR MANAGING A DATA GROUP IN A COMPUTER SYSTEM
A method for managing a data record in a computer system comprises: at least one computing server for hosting a computer session running with an operating system having a deduplication index and managing access to a session storage space; a shared storage space; an administration server for administering the shared storage space, executing a data management program; the computer session executing an interception program implementing the following steps: intercepting a read call to read at least one data record transmitted in the session; accessing the deduplication index and determining whether the data record is recorded in the shared storage space; if so, reading, from the deduplication index, the address of the data record in the shared storage space and redirecting the read call to this address; if not, overlooking the read call so that it is processed by the operating system.
