Chapter 9 Solution Configuration
9.2 Storage Optimization
■
Configuration Procedure
Automated Storage Tiering can be achieved by using the ETERNUS DX Flexible Tier function and the ETERNUS
SF Storage Cruiser functions.
●
Required Environment
For single tier pools, ETERNUS SF Storage Cruiser must be installed. For two or three tier pools, the ETERNUS
SF Storage Cruiser Optimization option must be installed.
●
Configuration Procedure
Set the tiering policy and the virtual storage pool in the operation management server (ETERNUS SF Storage
Cruiser).
For details on the settings, refer to "ETERNUS SF Storage Cruiser Operation Guide for Optimization Option".
9.2.2

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.
In addition, with Automated Storage Tiering, resources can be used efficiently and storage costs can be opti-
mized.
By automating the link between bandwidth adjustment and data redistribution with QoS, complicated stor-
age resource management can be simplified.
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.
