A data access method, system, device and storage medium are disclosed. In a case where there are data access hotspots in the original snapshot copy, multiple storage nodes are scheduled to concurrently read a data file of the original snapshot copy into memories of the multiple storage nodes, which can improve the efficiency of the storage nodes in reading the data file of the original snapshot copy. Based on data files in the memories of the multiple storage nodes, data to be accessed is provided to the instance, and memory caches of the multiple storage nodes may be used to accelerate the reading speed of the data to be accessed and reduce the data access delay. The multiple storage nodes are scheduled to dynamically generate a new snapshot copy based on the data files in the memories for a cloud disk to reference.

A method for preparing suspended graphene support film by selectively etching growth substrate is disclosed in present invention. The transfer process of graphene is avoided. The process of present invention is efficient and low in cost, suspended graphene support film can be prepared in a single etching step. The prepared graphene support film does not need any support by polymer film and polymer fiber. The prepared graphene support film has controllable number of layers and high intactness (90%-97%), large suspended area (diameter is 10-50 &#x3bc;m), wide clean area (&#x3e;100 nm) and can be mass-produced. In addition, the graphene support film can be directly used as transmission electron microscope support film, and can be used to achieve high resolution imaging of nanoparticles.

Electrodes, batteries, methods for use and manufacturing are implemented to provide ion-based electrical power sources and related devices. Consistent with one such method, a battery electrode is produced having nanowires of a first material. The electrode is produced using a single growth condition to promote growth of crystalline nanowires on a conductive substrate and of the first material, and promote, by maintaining the growth condition, growth of an amorphous portion that surrounds the crystalline nanowires.

A system and method is provided for providing assured recovery for a distributed application. Replica servers associated with the distributed application may be coordinated to perform integrity testing together for the whole distributed application. The replica servers connect to each other in a manner similar to the connection between master servers associated with the distributed application, thereby preventing the replica servers from accessing and/or changing application data on the master servers during integrity testing.

Mechanism to provide assured recovery for distributed application

A system and method is provided for ensuring high availability for a distributed application. A management object manages multiple scenarios defined for protection units associated with a distributed application. The management object may coordinate various operations performed at the protection units based on management object configuration information.

System and method for providing high availability for distributed application

A suite of network-based services, such as the services corresponding to Microsoft&#xae; SharePoint&#x2122;, are provided to users with high availability. The suite of network-based services may include browser-based collaboration functions, process management functions, index and search functions, document-management functions, and/or other functions. In particular, the indexing service associated with the suite of network-based services may be provided with high availability.

A suite of network-based services, such as the services corresponding to Microsoft&#xae; SharePoint&#x2122;, are provided to users with high availability. To maintain the availability of the services, the configuration parameters of a first server are updated on an ongoing basis, and the updated configuration parameters are used to configure a second, backup server. In the event of switchover or failover, the backup server is prepared to provide the serving functionality of the first server.

Chalcogenide-based nanowire memories are implemented using a variety of methods and devices. According to an example embodiment of the present invention, a method of manufacturing a memory circuit is implemented. The method includes depositing nanoparticles at locations on a substrate. Chalcogenide-based nanowires are created at the locations on the substrate using a vapor-liquid-solid technique. Insulating material is deposited between the chalcogenide-based nanowires. Lines are created to connect at least some of the chalcogenide-based nanowires.
