Methods and apparatus for receiving a selection of disks in a storage system for simulation in a simulator of a server cache application, receiving simulation parameters, running a simulation for the disk selection, and examining results of the simulation. After examination of the results, simulation parameters can be adjusted and the simulation re-run for a disk selection.

Methods and apparatus for server caching simulator

A computer-executable method, system, and computer program product for managing a data storage system, wherein the data storage system includes a cache and a data storage array, the computer-executable method, system, and computer program product comprising receiving initialization information, analyzing the initialization information to determine which portions of the data storage array related to the initialization information, and managing the data storage system based on the determined portion of the data storage array.

System, apparatus, and method of initializing cache

A computer-executable method, system, and computer program product for managing a data storage system, wherein the data storage system includes a cache and a data storage array, the computer-executable method comprising receiving a request to initialize a data storage system and initializing the data storage system by purging the cache.

System, apparatus, and method of securely erasing cache

An application services platform includes a platform chassis, a network interface supported by the platform chassis, and a control circuit supported by the platform chassis and coupled to the network interface. The control circuit is arranged to connect to a network through the network interface, and receive an application service command from a user. The application service command gives the control circuit permission to provide an application service to an application running on a server on the network. The control circuit is further arranged to provide the application service to the application running on the server on the network in response to receipt of the application service command. The application services platform is capable of being provided in the form of an appliance-style device which is simply added as a new device on the network.

Techniques for providing an application service to an application from an appliance-style application services platform

A method is used in managing data on data storage systems. Rules are defined for candidate data unit selection. The rules are automatically executed on a primary data storage system to examine data units on the primary data storage system. The rules are applied to the data units. A data unit is identified that matches the rules and the identified data unit is migrated. The identified data unit is copied from the primary storage system to a secondary storage system. The identified data unit on the primary storage system is replaced with metadata. the data storage space in the primary storage system corresponding to the identified data unit is freed up.

Managing data on data storage systems

A technique supports application operation. The technique involves discovering a set of applications running on an electronic system, and querying a user to identify which of the set of applications the user wishes to manage. The technique further involves, for each application identified by the user, providing an application service to that application to support operation of that application, the application service being separate from operating system services and security protection services provided by the electronic system.

Techniques for supporting application operation

For migration or de-duplication of a file system having a large number of files, a utility program traverses the file system to create a log of file-specific information about the file system. For identification of duplicates, the utility program produces a signature for each file. Respective instances of the utility program are started on multiple nodes upon which the file system is mounted. A fully qualified pathname is compiled during transfer of the log to a database. Multiple databases can be produced for the file system such that each database contains the file-specific information for a specified range of inode numbers. The database also maintains classification state for each file. For example, for a migration or replication process, the classification state identifies whether or not the file has been untouched, copied, linked, secondary-ized, source deleted, or modified.
