When migration is performed without retaining any backup disk, this function automatically switches physical disks immediately after data is copied to a destination physical disk.
A source physical disk used and retained for recovery purpose during migration.
Information that identifies a virtual enclosure for recognition by a SCSI interface.
A script executed by VSC Manager when saving the configuration information each time the resource status of virtual storage is changed and configuration information is updated.
A database that stores the relationship between resources in virtual storage, and which is the most important information of virtual storage. VSC Manager (which manages all configuration information) constantly checks the consistency between this information and each item of configuration information stored in a virtualization switch.
A file that records information on the start, stop, execution result, and other aspects of migration or replication.
A group of virtual enclosures that are subject to ETERNUS SF AdvancedCopy Manager copy security.
ETERNUS SF AdvancedCopy Manager
Software that links to Fujitsu's storage system ETERNUS and uses the advanced copy functions to perform high-speed backup, restore, and replication operations.
The Fabric OS (FOS) firmware that provides fibre channel switch functions.
IP address of Ethernet port for switch control
It is IP address to communicate with ETERNUS SF Storage Cruiser. This Internet Protocol address is specified by "Device search" of ETERNUS SF Storage Cruiser.
IP address of Ethernet port for virtualization control
It is IP address to do the communication between VSC Engine and the VSC manager.
The maximum number of copy sessions for virtual enclosures that are subject to ETERNUS SF AdvancedCopy Manager copy security.
A function that copies a physical disk that makes up a virtual disk(s) to another physical disk. The virtualization switch copies data from the source to the destination disk during migration.
Migration completion instruction
Refers to switching physical disks after data is copied to a destination physical disk.
The number of SCSI commands that a channel adapter (CA) for storage unit can accept concurrently
A logical unit (LUN) allocated from a disk unit. A physical disk is a storage medium that actually stores data and an element that makes up a virtual disk.
Refers to adding a physical disk to a virtual storage pool.
Refers to removing a physical disk from a virtual storage pool.
A function that copies the information of another virtual target (to which virtual disks are attached) into an arbitrary virtual target. This function is used for building a virtual disk environment in a multipath configuration.
A function that creates a copy of a virtual disk. The virtualization switch is used to copy data to a destination virtual disk.
A generic term for resources that are required to use the virtual storage function (virtual storage pools, virtual enclosures, virtual targets, virtual disks, and physical disks).
The program interface between Fabric OS and the VSC Engine.
Brocade agent program required by SMI-S for managing a virtualization switch.
A status in which the transaction server write request is executed to both the source and destination physical disks (during migration) to maintain data synchronization between these two disks.
It also refers to a status in which the transaction server write request is executed to both the source and destination virtual disks (during replication) to maintain data synchronization between these two disks.
A generic term for servers that run applications for accessing data on the connected virtual disks.
A logical volume independent of the physical attribute and size of a physical disk.
A logical enclosure for integrating virtual disks into an arbitrary unit.
A virtual WWPN used by a virtualization switch to access a storage device.
A generic term for the function that allows you to make a volume of an arbitrary size, independently of the attributes (e.g., size, RAID group) of logical units created on a disk unit.
A logical device that stores physical disks for constituting virtual disks.
A generic term for the operation interface (GUI) for the virtual storage function.
An access path for connecting a transaction server and a virtual disk.
Act of attaching a virtual disk to a virtual target.
A generic term for the "ETERNUS VS900 Model 200 Virtualization Switch" and "ETERNUS VS900 Model 300 Virtualization Switch", and "SN200 Model 540 Virtualization Blade", a fibre channel switch with the storage virtualization function.
A generic term for multiple groups (pairs) of virtualization switches in redundant configurations.
Firmware that runs on a virtualization switch. This firmware processes various requests regarding a virtual disk according to instructions from VSC Manager.
Manages the configuration information to form the foundation of the virtual storage function, handles and fowards processing requests issued via the virtual storage window to VSC Engine that runs on the target virtualization switch. VSC Manager runs on an admin server.
A necessary management area for using the replication suspend/resume function of ETERNUS SF AdvancedCopy Manager.
The suspend/resume function is enabled by using the area for virtual storage.
A number used to allocate a virtual disk to a virtual target. The VTHL number is the number of a disk recognized by a transaction server.
