For information on the basic system configuration required for using AdvancedCopy Manager CCM, refer to "Agent-less Operating Model" in "Overview of AdvancedCopy Manager" in the Overview.
System Configuration Using Both Copy Command via SAN and via LAN
With an inter-box copy, a configuration that can use both the Copy command via SAN and the Copy command via LAN is available.
Figure 1.1 Sample Configuration When Copy Command via SAN Is Used for Copy Source Device and Copy Command via LAN Is Used for Copy Destination Device
Figure 1.2 Sample Configuration When Copy Command via LAN Is Used for Copy Source Device and Copy Command via SAN Is Used for Copy Destination Device
Figure 1.3 Sample Configuration When Copy Command via LAN Is Used for Copy Source Device and Remote ETERNUS Disk Storage System Is Copy Destination Device
Point
It is recommended to not connect the copy destination logical volume to any server.
If performing REC using the Copy command via LAN function, it is necessary that both ETERNUS Disk storage systems are able to be operated by Copy command via LAN.
If the Copy command via LAN communicates with ETERNUS Disk storage system using SSH, the processing time increases compared with the Copy command via SAN. Moreover, it may take a few minutes to execute Advanced Copy functions by using Copy command via LAN depending on the number of copy pairs to which AdvancedCopy Manager CCM executes at a time.
If a copy is specified for copy groups with two or more copy pairs in an operating environment using the Copy command via LAN, regardless of the copy specification method (command, Web Console), the total processing time in relation to that copy group can be shortened by specifying a copy in units of copy groups rather than specifying a copy for the number of copy pairs in the copy unit.
It is recommended that you operate in units of copy groups when operating two or more copy pairs with the Copy command via LAN.
