Register Non-disruptive Storage Migration License
Overview
This function registers the Non-disruptive Storage Migration License.
By registering this license, the Non-disruptive Storage Migration function can be used.
For the Non-disruptive Storage Migration function, the volume information of the external storage system is inherited by the local storage system and the data is migrated without stopping operations in the local storage system. This license is registered in the local storage system.
This function is displayed only if the Non-disruptive Storage Migration License has not been registered.
By registering this license, the shared area in the cache memory is assigned for controlling the Non-disruptive Storage Migration function.
The shared area in the cache memory is not only used for the Non-disruptive Storage Migration function, but also used for copy tables, REC Buffers, the Thin Provisioning function (*1), the Storage Cluster function (*1), and the Extreme Cache function. Note that depending on the following, there are cases when this license may not be registrable.
Memory capacity in the storage system
Copy table size
REC Buffer size
Maximum pool capacity
Total TFOV capacity (*2)
Extreme Cache setting (enabled) and Extreme Cache capacity
For the ETERNUS DX60 S5, a registration error for this license due to insufficient memory capacity does not occur because the ETERNUS DX60 S5 uses an area other than the shared area in the cache memory.
*1 : The shared area in the cache memory is used for the following conditions. - The maximum pool capacity is expanded to "1.5 PB" or larger
The total TFOV capacity (*2) has been expanded from the default capacity
Refer to the descriptions about "Storage Cluster" in the [System] screen for the default capacity of the TFOV for each model.
*2 : The total TFOV capacity indicates the total capacity of the volumes that are used for the Storage Cluster function in a storage system. Delete this license immediately after the data migration is completed successfully. Deleting this license releases the shared area in the cache memory that is acquired for controlling the Non-disruptive Storage Migration function. Refer to the [Delete Non-disruptive Storage Migration License] function for details.
The registration status of this license can be checked. Refer to the [System] function for details.
Because the RAID Migration function is used for migrating data, the maximum number of simultaneous processes is 32 and the total capacity of the simultaneous processes is 128 TB.
