Abstract: A technique involves determining, in redundant array of independent disks (RAID) stripes, source slices for restriping, and allocating, from a reserved capacity for file system check (FSCK), destination slices for restriping. The technique further involves performing restriping for the RAID stripes by copying data in the source slices into the destination slices. Accordingly, using the reserved capacity for FSCK as the destination slices for restriping may mitigate the influence on an available capacity of a mapper during restriping, thereby improving the performance of a storage system.

Abstract: This document describes techniques for storing virtual disk payload data. In an exemplary configuration, each virtual disk extent can be associated with state information that indicates whether the virtual disk extent is described by a virtual disk file. Under certain conditions the space used to describe a virtual disk extent can be reclaimed and state information can be used to determine how read and/or write operations directed to the virtual disk extent are handled. In addition to the foregoing, other techniques are described in the claims, figures, and detailed description of this document.

Abstract: Systems and methods for performing backup operations and other secondary copy operations for mail servers, such as Exchange servers, are described. In some cases, the systems and methods perform multi-streaming backup and other copy operations using a single mailbox agent, which launches backup streams via a coordinator that determines when to launch streams, at what mailboxes (or folders) to launch the streams, and so on. The coordinator communicates with controllers at different machines (e.g., servers) to be backed up, and may assign streams, mailboxes, and so on, to the different controllers, which perform the backup operations for their assigned mailboxes and/or clients.

Abstract: A hybrid addressing scheme in which a maximum of three codeword groups are utilized across pairs of memory dice and/or access rows of the memory sub-system or memory device is provided. By controlling the arrangement of such codewords, it can be possible to group codewords such that disturb effects can be reduced. For example, codewords can be grouped in a symmetrical manner with respect to the memory dice of a memory device, which can allow for simplified codeword addressing.

Abstract: Features are disclosed for forecasting a usage of a block storage volume with a first configuration by a user. A computing device can forecast the usage of the block storage volume based on the historical usage of the block storage volume by the user.

Abstract: According to one embodiment, a buffer stores first hash values and first complementary data. A first conversion unit converts consecutive characters in a second character string into second hash values and second complementary data. A search unit searches for consecutive first hash values from the buffer, and output a pointer.

A second conversion unit converts the consecutive first hash values into a third character string using the pieces of first complementary data. A comparison unit compares the second character string with the third character string to acquire a matching length. An output unit output the matching length with the pointer.
