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, the SCU does not have a time limit to save
data. The SCU is charged so quickly that write performance is recovered right after power
recovery.

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 Council of Europe
and our board of directors. RoHS limits the use in electric and electronic equipment of six specific
chemicals: lead, hexavalent chromium, mercury, cadmium, PBB (polybrominated biphenyl), and
PBDE (polybrominated diphenyl ether). In addition, lead-free soldering is used for all printed-wir-
ing boards.
Data encryption may not be possible for some configurations.
