    Abstract: A storage management method includes receiving a degrade signal indicating a degraded state of a virtual disk associated with a host system. Rebuild-flush operations may be performed. The operations may include writing, to the virtual disk and also to a hot spare drive (HSP) associated with the virtual disk, valid-modified data, stored in a host storage cache, associated with the virtual disk. In contrast, valid-unmodified storage cache data associated with the virtual disk, may be written to the HSP only. After the rebuild-flush completes, the virtual disk may be rebuilt. During rebuild, however, any cached-LBA may be skipped where traditional RAID rebuild operations are performed for un-cached LBAs only.

  • Patent number: 9917896
    Abstract: One or more techniques and/or computing devices are provided for implementing synchronous replication. For example, a synchronous replication relationship may be established between a first storage controller hosting local storage and a second storage controller hosting remote storage (e.g., replication may be specified at a file, logical unit number (LUN), or any other level of granularity). Data operations and offloaded operations may be implemented in parallel upon the local storage and the remote storage. Error handling operations may be implemented upon the local storage and implement in parallel as a best effort on the remote storage, and a reconciliation may be performed to identify any data divergence from the best effort parallel implementation. Storage area network (SAN) operations may be implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.

  • Patent number: 9880740
    Abstract: A computer system provides for rapid power-on operations on virtual machines (VMs) with a virtual memory space including a reservation from machine memory and a small or no swap size. When the computer system powers on a VM, the computer system creates a physical memory space for the VM with a size larger than the minimum memory reservation for the VM and a swap space with a size less than the difference between the size of the virtual memory space and the minimum memory reservation. Subsequently, the computer system iteratively decreases the size of the physical memory space for the VM and increases the size of the swap space for the VM until the size of the physical memory space equals the minimum size of the memory reservation, which may be the amount of the virtual space that is guaranteed to be backed by machine memory.

  • Patent number: 9870412
    Abstract: A cluster manager manages copies of a mid-tier database as a mid-tier database cluster. The cluster manager may concurrently manage a backend database system. The cluster manager is configured to monitor for and react to failures of mid-tier database nodes. The cluster manager may react to a mid-tier database failure by, for example, assigning a new active node, creating a new standby node, creating new copies of the mid-tier databases, implementing new replication or backup schemes, reassigning the node's virtual address to another node, or relocating applications that were directly linked to the mid-tier database to another host. Each node or an associated agent may configure the cluster manager during initialization, based on common cluster configuration information. Each copy of the mid-tier database may be, for example, a memory resident database. Thus, a node must reload the entire database into memory to recover a copy of the database.

  • Patent number: 9823842
    Abstract: Gang migration refers to the simultaneous live migration of multiple Virtual Machines (VMs) from one set of physical machines to another in response to events such as load spikes and imminent failures. Gang migration generates a large volume of network traffic and can overload the core network links and switches in a datacenter. In this paper, we present an approach to reduce the network overhead of gang migration using global deduplication (GMGD). GMGD identifies and eliminates the retransmission of duplicate memory pages among VMs running on multiple physical machines in the cluster. The design, implementation and evaluation of a GMGD prototype is described using QEMU/KVM VMs. Evaluations on a 30-node Gigabit Ethernet cluster having 10 GigE core links shows that GMGD can reduce the network traffic on core links by up to 65% and the total migration time of VMs by up to 42% when compared to the default migration technique in QEMU/KVM.

  • Patent number: 9792069
    Abstract: A method for managing a flash storage system includes reading flash data units from flash memory into a buffer, wherein each of the flash data units includes host data units, and determining an identifier for each host data unit. The method includes selecting a set of unique identifiers from the determined identifiers based on a number of host data units sharing the respective unique identifier. For each unique identifier in the set of unique identifier, the method includes designating one of the host data units as a master data unit, wherein the logical address of the designated host data unit is mapped to a physical address. The logical addresses of the other host data units sharing the unique identifier are remapped to the master physical address, and the physical addresses previously mapped to the remapped logical addresses are invalidated.

  • Patent number: 9766987
    Abstract: The data storage system according to certain aspects can implement table level database restore. Table level database restore may refer to restoring a database table and its related data without restoring the entire database. The data storage system may use table metadata index to implement table level restore. A table metadata index may be created for each table, e.g., during a backup of the database. The table metadata index for a table can include any type of information for restoring the table and its related data. Some examples of the type of information included in the table metadata index include the following: container for the table, table backup location, system data, table index, table relationships, etc. Table metadata index can make the restoring of tables fast and efficient by packaging information that can be used to restore a table and its related data in an easily accessible manner.
