摘要:
A multi-protocol storage appliance serves file and block protocol access to information stored on storage devices in an integrated manner for both network attached storage (NAS) and storage area network (SAN) deployments. A storage operating system of the appliance implements a file system that cooperates with novel virtualization modules to provide a virtualization system that “virtualizes” the storage space provided by the devices. Notably, the file system provides volume management capabilities for use in block-based access to the information stored on the devices. The virtualization system allows the file system to logically organize the information as named file, directory and virtual disk (vdisk) storage objects to thereby provide an integrated NAS and SAN appliance approach to storage by enabling file-based access to the files and directories, while further enabling block-based access to the vdisks.

A system and method for clustered failover of storage appliances is provided. In the event of a failover of one storage appliance to a surviving storage appliance, the surviving storage appliance assumes the identity of the failed storage appliance. This assumption of the identifier is accomplished by initializing a Fibre Channel Host Bus Adapter on the surviving storage appliance with the NodeName and PortNames of the failed storage appliance.

A system and method for optimizing lun masking of a storage appliance is provided. Upon login, an initiator data structure containing a lun map is created and associated with each initiator connected to the storage system. When an initiator sends a message directed to a lun associated with the storage system, the storage system maps the lun sent by the initiator to a physical lun associated with the storage system using the lun map. If the lun map contains an appropriate entry, then the lun has been successfully exported and/or masked to the given initiator.

A system and method for clustered failover of storage appliances is provided. In the event of a failover of one storage appliance to a surviving storage appliance, the surviving storage appliance assumes the identity of the failed storage appliance. This assumption of the identifier is accomplished by activating a network interface controller or host bus adapter with a network address associated with the failed storage appliance and by mapping a iSCSI name from the failed storage appliance to the surviving storage appliance.

摘要:
A technique enables efficient access to logical unit numbers (luns) or virtual disks (vdisks) stored on a storage system, such as a multi-protocol storage appliance. The technique allows a grouping of initiators by a “human friendly” logical name that is mapped to a lun or vdisk on the storage appliance. The initiators are clients operating in, e.g., a storage area network (SAN) environment that initiate requests for the vdisk using block-based access protocols, such as the Small Computer Systems Interface (SCSI) protocol encapsulated over TCP/IP (iSCSI) or over fibre channel (FCP). The technique enables access to the vdisk by all initiators that are members of the initiator group (igroup). An igroup is a logical named entity that is assigned to one or more addresses associated with one or more initiators. These addresses may comprise fibre channel (FC) world wide name (WWN) or iSCSI name identifiers (IDs). Therefore, rather than having to specify these IDs when desiring access to a vdisk, an initiator need only specify the human friendly name of the igroup.

Implementations described and claimed herein provide a method comprising generating a plurality of prompts, each of the plurality of prompts related to one of a plurality of elements, generating an indexed prompt file (IPF) comprising one or more of the plurality of prompts and index information about the one or more of the plurality of prompts, and generating an IPF map file relating one or more of the elements to one or more of the plurality of prompts using the index information. The method further comprises mapping a target phone number to the one or more of the plurality of elements, the target phone number being associated with a target on a target list, generating a call to the target phone number, and playing the one or more of the plurality of prompts based on the index information.

A system and method for providing persistent node names is provided. The system and method stores the node name associated with a given storage system in the root volume associated with the storage system. Thus various components of the storage appliance may be modified without changing the node name associated with a given storage system. This enables clients to have a consistent and persistent node name to connect to in a given network environment.

A method and system for enabling a network service provider to monitor a packet network by using call detail records (CDRs) are disclosed. The method first detects a termination of a call by at least one voice gateway router and generates a call detail record (CDR) at said termination of said call by said at least one voice gateway router. The method then forwards said call detail record by said at least one voice gateway router to at least one CDR collecting and analysis server.
