Chapter 1 Overview
1.1 System Features
●
Block Guard ensures data integrity
The ETERNUS DX60/DX80/DX90 adds check codes and check them at multiple checkpoints
on data transfer path to ensure the data integrity.
●
System Capacitor Unit (SCU)
A SCU that does not need to be regularly replaced is installed as a backup power source in
case of a power failure. If the power fails, the SCU enables the cache memory data to be
saved to flash memory. Therefore, unlike a battery, data is safely stored for an indefinite
period. The SCU is charged so quickly that write performance is recovered right after power
recovery.
■
E-mail notification
If an error occurs in the ETERNUS DX60/DX80/DX90, the details can be sent to a specified e-
mail address.
■
Strengthening security against information leaks
●
Data encryption to prevent information leaks
Data can be encrypted and written. Data encryption can prevent information leaks caused by
fraudulent decoding even if the disk is stolen.
●
Protection against fraudulent access
The ETERNUS DX60/DX80/DX90 supports SSL/SSH that encrypts and communicates
information on the network. This protects against malicious use of data and fraudulent access
to devices via a Web browser (GUI) or CLI.
■
RoHS compliance
The ETERNUS DX60/DX80/DX90 complies with RoHS, as mandated by the European Parlia-
ment and Council. RoHS limits the use in electric and electronic equipment of six specific chemi-
cals: lead, hexavalent chromium, mercury, cadmium, PBB (polybrominated biphenyl), and PBDE
(polybrominated diphenyl ether). In addition, lead-free soldering is used for all printed-wiring
boards.
Data encryption may not be possible for some configurations.
