Abstract: A data storage array may be made up of several storage devices, each of which may contain array metadata that may allow portions of the storage array to be used. A system may have a file system manager that may receive and respond to file system commands and a storage device manager that may store data on the several storage devices. Array metadata defining where data is stored within the storage array is stored on each device within the array. A policy engine may identify data to be stored on the array and determine if the data contains array metadata or other types of data and may store the data on every device, devices having specific characteristics, two or more devices, or one device.

Abstract: Disclosed is a method for creating and reading a contiguous file in an extensible file system. During the creation of a file on the storage media, the file system format check the bitmap to determine if there are areas of free space on the media that would permit the storage of the file in a contiguous manner. By storing the file in a contiguous manner the file may later be read without resorting to the file allocation table, because the file itself would not be fragmented on the storage media. Once an area of free space has been identified, the file is written to the media in a contiguous manner. Further, an associated entry for the file in the directory entry is updated or created to indicate that the file is a contiguous file and also provides basic parameters necessary to read the file without resorting to accessing the file allocation table.

Abstract translation: 公开了一种在可扩展文件系统中创建和读取连续文件的方法。 在存储介质上创建文件期间，文件系统格式检查位图，以确定介质上是否存在允许以连续方式存储文件的可用空间区域。 通过以连续的方式存储文件，可以稍后在不依赖于文件分配表的情况下读取文件，因为文件本身不会在存储介质上分段。 一旦确定了可用空间区域，文件将以连续的方式写入介质。 此外，更新或创建目录条目中的文件的相关条目以指示文件是连续文件，并且还提供读取文件所必需的基本参数，而无需访问文件分配表。

Abstract: A storage monitoring system may reside between a file system and a storage system in a thin provisioned storage system. The storage monitoring system may create space holder files within a volume, where the space holder files contain an address space not backed up with physical storage. As requests for storage space are received from a file system, the storage monitoring system may allocate physical space to the volume by provisioning portions of the physical storage device to the volume and by removing one of the space holder files. The storage monitoring system may present alerts when physical storage space is low, as well as return an amount of physical space available to a volume size request.

Abstract: An extensible file system format for portable storage media is provided. The extensible file system format includes the specification of primary and secondary directory entry types that may be custom defined. The primary and secondary directory entry types can be further classified as critical and benign directory entries. The directory entry types can define whether a cluster chain corresponding to a file can be contiguously allocated.

Abstract: A method and system for storing the data of files having duplicate content, by maintaining a single instance of the data, and providing logically separate links to the single instance. Files of duplicate content have their data stored in a common store file by a single instance store (SIS) facility, which also converts the original file or files to links to that common store file and creates additional links thereto as needed. The SIS facility may reside above a file system as a filter driver. File system requests directed to the link file (e.g., open, write, read, close and delete) reach the SIS filter, which then transparently handles each request as if the link file was a normal file. To preserve logical separation, writes to a SIS link file are to the link file, and the written portion recorded as dirty. The SIS filter intercepts SIS read requests, and reads clean portions from the common store file and any dirty portions from the link file. When the link file is closed, the common store file also may be closed, and, if the link file has been written, the non-dirtied portions of the link file are filled in with clean data from the common store file, and the link file reconverted to a normal file. Security is provided to prevent unauthorized access to the common store files, as is a volume check facility that repairs any inconsistencies in SIS metadata.

Abstract: A thin provisioned storage system may have a file system manager that presents a logical storage system to a user and a storage management system that manages physical storage devices. When a block of data is freed at the logical layer, the file system manager may identify the freed block and send a command to the physical layer. The physical layer may identify the corresponding physical block or blocks and free those blocks on the physical layer. The storage management system may use a table to manage the location of blocks of data across multiple physical storage devices.
