Function

The ETERNUS DX provides various functions to ensure data integrity, enhance security, reduce cost, and optimize
the overall performance of the system.
These functions enable to respond to problems from various situations.

Table 1 Basic Functions

Overview
Data protection
Functions that ensure data integrity to improve data reliability.
It is possible to detect and fix drive failures early.
Resource utilization (virtualization)
Functions that deliver effective resource utilization.
• Data capacity expansion
Functions that expand or relocate a RAID group or a volume
in order to flexibly meet any increases in the amount of data.
Guarantee of performance
•
A function that creates a volume that is striped in multiple
RAID groups in order to improve performance.
Security measures (user access management)
Functions to prevent information leakage that are caused by a
malicious access.
Security measures (unauthorized access prevention)
Functions that prevent unintentional storage access.
Environmental burden reduction
Functions that adjust the operating time and the environment
of the installation location in order to reduce power consump-
tion.
Operation management (device monitoring)
Function that reduce load on the system administrator, and
that improve system stability and increase operating ratio of
the system.
Power control
Power control functions that are used to link power-on and
power-off operations with servers and perform scheduled opera-
tions.
• High-speed backup
Continuous business
•
Data can be duplicated at any point without affecting other op-
erations.
Performance Tuning
Functions that can perform tuning in order to improve perform-
ance.
Stable operation
For stable operation of server connections, the appropriate re-
sponse action can be specified for each server.
