Set Copy Path
Overview
This function sets copy path information between the storage systems required for performing REC using the wizard screen.
Copy path information indicates the path (copy path and the storage system where the copy path is set) used for performing REC.
Not only copy path information of the local storage system but also the information between remote storage systems can be created.

The Maximum Number of Remote Storage Systems, Paths, and Ports
Up to 16 remote storage systems can be connected from one storage system.
Up to 8 copy paths can be created between a pair of storage systems.
Up to 32 destination ports (FC-RA) can be connected from one port.
Up to 16 destination ports (iSCSI-RA) can be connected from one port.
In the [Set Copy Path] function, the storage system that is used to create copy paths is referred to as "local storage system" and the storage system that is connected to is referred to as a "remote storage system".
The [Set Copy Path] function provides the following functions:
Register Storage System Information
Create Copy Path
Apply Copy Path
Save
Set Bandwidth Limit
Measure Round Trip Time
Registering the Advanced Copy function license or the Storage Cluster function license (*1) is required to use this function.
Creating copy paths in the ETERNUS DX100 S4/DX100 S3 is only available when the local storage system (the storage system where copy paths are created) is purchased outside Japan.
To create copy path information between different generations of storage systems (such as ETERNUS DX600 S5 and ETERNUS DX200 S4), be sure to create the information on the newer model of storage system (ETERNUS DX600 S5 in the above example). The copy path creating function on an older model may not have a function to add the storage system information for newer models or the created path information file cannot be applied to newer models.
To create copy path information between the ETERNUS DX8000 S4 series and the ETERNUS DX S5 series, create the information on the ETERNUS DX S5 series.
If the created path information and the path information in the storage system do not match and some of the copy paths to the storage system are not selected to be applied, the actual path information after the application does not correspond to the contents of the backed up path information file. Refer to "Specification for Applying Result" for details. Note that the backup path file corresponds to the downloaded path information file that is saved in the setting PC.
- Furthermore, note the following points for modifying the copy path information.
When adding a new copy path in the storage system where copy paths already exist, create path information files for all the copy paths including the existing paths.
If the Box ID is changed after the copy path is set, REC will no longer run. After creating the copy path information with the new Box ID, apply the new copy path information to all the storage systems that have copy paths to the storage system for which the Box ID was changed.
Modifying copy path information in use may stop or otherwise affect operations. Confirm that REC is not in use before modifying the information. To check whether REC is in use, refer to the copy session list of Remote Copy.
- An REC between ETERNUS DX S5 series or ETERNUS AF S3 series and the following models is not supported (*2).
- ETERNUS DX410 S2/DX440 S2/DX8100 S2/DX8700 S2/DX90 S2
- ETERNUS DX90
- ETERNUS DX410/DX440/DX8100/DX8400/DX8700
- ETERNUS4000/ETERNUS8000
- ETERNUS6000
*1 | : | The Storage Cluster function license must be registered using ETERNUS SF Storage Cruiser. |
*2 | : | These are the storage systems other than ETERNUS DX60 S5. |
Only copy path information files created/saved with this function can be loaded with this function.
The storage system information file that can be loaded by using this function is the file that can be obtained and downloaded from "Storage Systems That Can Be Used as Remote Storage Systems".
Use the [Delete All Copy Path] function to delete the copy path information in the local storage system. The copy path information of the local storage system is initialized.
The round trip time can be measured only between the local storage system and a remote storage system that has a physical path to the local storage system. When a copy path is created between remote storage systems, apply a copy path information file to the applicable storage system before measuring the round trip time.
The round trip time can be measured only when the connection type is "Remote".
To change the measured round trip time, use the [Measure Round Trip Time] function.
To change the line speed, use the [Set REC Line Speed] function. The line speed can be set only when the "Connection Type" is "Remote".

Up to 5-digit decimal number 1 - 65535 (Mbit/s) |
Setting Example of Line Speed
For the "Line Speed" field, specify the WAN bandwidth (a total of multiple lines, if used) that can be actually used for REC. For some cases such as using the bandwidth control device, the WAN bandwidth that can be used for REC is designated. In this case, specify the designated value. To control WAN bandwidth, using the bandwidth control device is required.
When using a carrier equipment with the compression function, specify the bandwidth (a total of multiple lines, if used) that can be used after compression. In the ETERNUS storage systems, data compression is unavailable. To compress data, using a carrier equipment with the compression function is required.
(Example 1): When the bandwidth control device is not used
Line bandwidth (*2): 200 Mbit/s (All available for REC)
The number of lines (*3): 4 (200 Mbit/s for all)
Line speed = 200 (Mbit/s) × 4 = 800 (Mbit/s)
(Example 2): When the bandwidth control device is used
Line bandwidth with bandwidth limit (*2): 100 Mbit/s (100 Mbit/s out of 200 Mbit/s line bandwidth is available for REC)
The number of lines (*3): 2 (100 Mbit/s for all)
Line speed = 100 (Mbit/s) × 2 = 200 (Mbit/s)
(Example 3): When the line device has no compression function
Line bandwidth (*2): 200 Mbit/s (All available for REC)
The number of lines (*3): 2 (200 Mbit/s for all)
Compression ratio: 0 (%) (No compression)
Line speed = 200 (Mbit/s) × 2 ÷ (1 - 0 (%)) = 400 (Mbit/s)
(Example 4): When the line device has the compression function
Line bandwidth (*2): 200 Mbit/s (All available for REC)
The number of lines (*3): 2 (200 Mbit/s for all)
Compression ratio: 20 (%) (20% for all)
Line speed = 200 (Mbit/s) × 2 ÷ (1 - 20 (%)) = 500 (Mbit/s)
*2 | : | The line bandwidth that the user has signed up to be used for REC |
