System Configuration

Hardware Configuration

Select hardware components according to the business conditions, requirements, disk
capacity, and so forth. Figure 1-1 shows an example of hardware configuration.
• To utilize the snapshot function most efficiently, it is better to separate application
servers, which process tasks, from backup servers. Thus, tape backup operation gives
no additional load to application servers.In the environment using VxVM, it is not
possible to operate BV and a snapshot on the same server. Therefore, the application
server used for operations should be different from the backup server. In the
environment using LVM, it is possible to operate both on the same server, but you need
to take care about the procedures for operations.
• Though the business or backup server may also be used as a management server,
using a specific management server is recommended. Use of LAN connection is
strongly recommended for connection with disk array.
• 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 Access
Control.

Software Configuration

Select software to be used according to the hardware components, operating conditions, etc.
