Abstract: Example apparatus, methods, and computers prevent a split brain scenario in a pair of high availability servers by maintaining single writer access to a resource. One example method includes monitoring control of an arbitration (ARB) block by an active file system manager (FSM). An active file system portmapper (FSMPM) simultaneously requests permission from a standby FSM to restart a dead-man timer. The active FSM attempts to maintain control of the ARB block before expiration of the dead-man timer. If the active FSM is unable to maintain control of the ARB block before expiration of the dead-man timer, a hardware reset of an apparatus running the active FSM is forced. Therefore, the active FSMPM and standby FSM negotiate for additional time to maintain control of the ARB block to maintain single writer access and avoid unnecessary hardware resets.

Abstract: In a method of writing data to a file system on a solid state drive, a file stream is opened for writing to a file in the file system. A life expectancy value predicting a length of time the data to be written will be stored in the file system is attached to the file stream. The data is written to the file stream and stored on the solid state storage device according to the life expectancy value attached to the data. In one embodiment, a unique identifier may be used as the life expectancy value for writing a group of related files predicted to be stored in the file system for substantially the same length of time. The life expectancy value may be predicted based on a file type of the file being written. The life expectancy value may be stored as metadata for the file being written.

Abstract: A method for storing electronic data blocks at a storage facility uses a public database and a select database. Hash for each data block is evaluated at the facility to determine whether the data block is already stored at the facility. New data blocks are assigned a new address in the select database when encrypted with a customer key. Otherwise, they are assigned a new address in the public database by default. Duplicate data blocks are assigned a previously established address for the data block in either the public or select database. All addresses are then sent to the customer location for file integrity and only the content of new data blocks need to be sent to the storage facility (i.e. no need for duplicates).

Metadata for the container is stored on the primary data store. Zero or more objects are stored in the container on the primary data store. For each of the secondary data stores that have objects belonging to the group, a container is created in that secondary data store having the unique identifier, wherein the container spans the primary data store and the secondary data stores, and wherein the objects in the container do not span the primary data store and the secondary data stores.

Abstract: A cluster based file service may operate on a cluster of two or more independent devices that have access to a common data storage. The file service may have a namespace definition with each device in the cluster, but may be modified by any device operating the file service. Each instance of the file service may identify and capture a command that changes the namespace structure and cause the change to be propagated to the other members of cluster. If one of the devices in the cluster does not successfully perform an update to the namespace structure, that device may be brought offline. The cluster based file service may permit adding or removing devices from the cluster while the file service is operating, and may provide a high throughput and high availability file service.

Abstract: Data can be transferred between computers at remote sites by transferring the data itself, or by transferring files showing how data at an originating site can be recreated from data already present at a receiving site. As part of the data transfer, a determination can be made as to what is the most appropriate way for the transfer to take place. Further, in cases where data is not transferred directly between originating and receiving sites, it is possible that some preparatory steps might be performed to improve the efficiency of the transfers to the receiving sites when they do take place. Additional efficiencies can be obtained in some cases by using the parallel processing capabilities provided by a cloud based architecture.
