Solution Overview
The performance of existing systems may be affected when the number of servers that access the ETERNUS
DX increases due to increased operations. The process performance that the user sets as the target value can
be automatically adjusted by using ETERNUS SF Storage Cruiser to automate QoS. This guarantees the band-
width for a server according to the operation priority to reduce the effect on one server from another server,
which results in the performance of a server with high priority and important operations to be guaranteed.
Efficient operation can be achieved when the response performance of different operations are guaranteed
in different time periods. Examples of this include when the Exchange server and backup applications exist
together, and the Exchange environment is given priority during daytime and backup application operations
are given priority during nighttime.

The bandwidth of the server with high
priority operations is secured by
reducing the bandwidths of the servers
with low priority operations.
