■
Configuration Procedure
Automated Storage Tiering can be achieved by using the Flexible Tier function of the ETERNUS DX and the
function of ETERNUS SF Storage Cruiser.
●

Performance/Tuning

■
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 Quality of Service (QoS). This
guarantees the bandwidth 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.
