20120136830 | MECHANISM FOR EFFICIENT DELAYED REPLICATION - A mechanism for efficient delayed replication is described. A method of embodiments of the invention includes detecting input/output (I/O) requests issued by a software program running on a computer system, and sorting the I/O requests into I/O batches according to flight overlapping of the I/O requests. An I/O batch includes a set of flight-overlapped I/O requests of the I/O requests. The set of flight overlapped I/O requests includes two or more I/O requests that are issued, at least partially, in parallel. The method further includes replicating the I/O requests to a storage medium coupled to the computer system. | 05-31-2012 |
20130318319 | SYSTEMS AND METHODS FOR MANAGING ZEROED LOGICAL VOLUME - A mechanism for zeroed logical volume management is disclosed. A method includes assigning, by a computing device, a bit value to each of storage blocks in a data volume of an operating system. The method also includes permitting, by the computing device, data in the storage blocks of the data volume to be read if the bit value is set to 1. The method further includes preventing, by the computing device, the data in the storage blocks of the data volume to be read if the bit value is set to 0. | 11-28-2013 |
20150227317 | PERFORMING DISCARD COMMANDS ON RAID STORAGE DEVICES - An example method for performing discard commands on Redundant Array of Independent Disks (RAID) devices may comprise receiving a request to free a range of logical sectors that is mapped to a plurality of storage devices organized as RAID. The method may further comprise identifying a first physical sector number corresponding to a first logical sector having a lowest number greater or equal than a starting logical sector number of the range of logical sectors. The method may further comprise identifying a second physical sector number corresponding to a second logical sector having a lowest number greater or equal than an ending logical sector number of the range of logical sectors. The method may further comprise issuing a single command to all of the plurality of storage devices to free a range of sectors identified by the first physical sector number and the second physical sector number. | 08-13-2015 |
