Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a clustered storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.

Method and system for managing metadata in a storage environment

A data security appliance intercepts out-of-band control traffic directed to a data storage device, wherein the out-of-band control traffic includes a command to change a configuration of the data storage device. The data security appliance is reconfigured in accordance with the command in order to conform with a new configuration of the data storage device.

Storage security appliance with out-of-band management capabilities

A security appliance that encrypts and decrypts information is installed in each of redundant multi-paths between a host system and a back up tape storage system. The host system is arranged to detect failures in a primary path to the tape system being used. When the failure is detected, the host system enables transfers to the same tape system through an alternative path. Encryption keys and host/tape designators (identifiers) are broadcast among the security appliances in the alternative data paths. When the host system switches from the primary path to the secondary path, even though the secondary security appliance did not generate the encryption keys, the secondary path security appliance will have such keys and will properly encrypt and transfer data from the host to the tape system. The secondary will also properly retrieve encrypted data from the tape system, decrypt it and deliver it to the host. All of these operations will be transparent (invisible) to a running application in the host.
