Select hardware components according to the business conditions, requirements, disk capacity, and so 
forth.    Figure 1-1 shows an example of hardware configuration. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Figure 1-1    Hardware Configuration Example 
 
• 
To utilize the data replication function most efficiently, it is better to separate business servers, 
which process tasks, from backup servers.    Thus, tape backup operation gives no additional load 
to business servers. 
• 
When doing disk backup instead of tape backup, no backup servers are required. 
• 
Though the business or backup server may also be used as a management server, using a specific 
management server is recommended.    To avoid conflicts with host accesses, use of LAN 
connection is strongly recommended for connection with disk array. 
• 
The disk array accepts any tape drives.    Select one of drives authorized by the backup software to 
be used. 
• 
Connect the path of individual servers, to be connected to the disk array, to the port of different 
directors of the disk array, limiting the servers to be accessed by AccessControl. 
• 
In the configuration example, the business servers are installed in a cluster and mutually connected 
through the LAN specific to interconnection. 
• 
Using data replication in the 4000 series or 3000 series requires a separate replication director.
