Function Specification List

Function Specification List
The ETERNUS DX provides various functions to ensure data integrity, enhance security, reduce cost, and optimize
the overall performance of the system.
The ETERNUS DX integrates block data (SAN area) and file data (NAS area) in a single device and also provides
advanced functions according to the SAN or NAS connection.
These functions enable users to respond to problems from various situations.
The ETERNUS DX has functions such as the SAN function (supports block data access), the NAS function (supports
file data access), and basic functions that can be used for both SAN and NAS connections.
For more details about basic functions, refer to
functions that are used for a SAN connection, refer to
functions that are used for a NAS connection, refer to
Table 8 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/
Automated Storage Tiering)
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
Functions that create a volume that
is striped in multiple RAID groups in
order to improve performance.
Security measures (data encryption)
Functions that encrypt data in the drive
media to prevent the data from being
fraudulently decoded.
Security measures (user access
management)
Functions to prevent information
leakage that is caused by a malicious
access.
