| 20100070546 | Providing Local File Storage within a Java Server Environment - A local file storage is provided for a virtual machine running on a server. A common directory is created on the local file storage, including files usable by the virtual machine. A private directory is created on the local file storage, including user files accessible only by a single user of the virtual machine, wherein each virtual machine user has a separate private directory. The common directory and the private directory are accessed via the virtual machine and a common nomenclature, whereby the implementation of the common directory and the private directory on the local file storage is hidden from the user. The virtual machine may be accessed through a host environment, and each host environment user has a separate private directory. | 03-18-2010 |

| 20150046504 | EXTENSION OF WRITE ANYWHERE FILE LAYOUT WRITE ALLOCATION - A write allocation technique extends a conventional write allocation procedure employed by a write anywhere file system of a storage system. A write allocator of the file system implements the extended write allocation technique in response to an event in the file system. The extended write allocation technique efficiently allocates blocks, and frees blocks, to and from a virtual volume (vvol) of an aggregate. The aggregate is a physical volume comprising one or more groups of disks, such as RAID groups, underlying one or more vvols of the storage system. The aggregate has its own physical volume block number (pvbn) space and maintains metadata, such as block allocation structures, within that pvbn space. Each vvol also has its own virtual volume block number (vvbn) space and maintains metadata, such as block allocation structures, within that vvbn space. The inventive technique extends input/output efficiencies of the conventional write allocation procedure to comport with an extended file system layout of the storage system. | 02-12-2015 |
