FUJITSU ETERNUS DX80 
DISK STORAGE SYSTEM 
 
THE DATA SAFE 
 
 
 
 
ENTRY-LEVEL DISK STORAGE SYSTEMS 
Fujitsu ETERNUS DX60/DX80/DX90 entry level disk 
storage systems are a new generation of storage 
systems with enterprise class reliability. 
Especially designed for small and medium-sized 
businesses, ETERNUS DX60/DX80/DX90 are highly 
reliable and secure Data Safes. 
 
Easy to install, configure, operate and maintain, 
ETERNUS DX60/DX80/DX90 integrate well with host 
operating systems, servers, network infrastructures 
and backup solutions.   
 
Different drive types can be mixed and securely 
monitored using appropriate RAID levels (0, 1, 1+0, 
5, 5+0 and 6). This ensures growth flexibility and 
data integrity. Administrators can dynamically move 
data, spin down disks to save energy, and encrypt 
data to prevent unauthorized access. In the event of 
a power outage, the content in the cache is secured 
on flash memory. Backup copies are always at hand 
via snapshots and clones. 
 
ETERNUS SF Express management software, 
provided with ETERNUS DX60/DX80/DX90, simplifies 
the monitoring and management of multiple 
ETERNUS DX disk storage systems from a central 
console. In addition, ETERNUS SF Express manages 
the Advanced Copy functions for data backup using 
snapshots and clones. 
 
ETERNUS DX80 
ETERNUS DX80 is a versatile, reliable and very 
effective disk storage system for small and 
medium-sized businesses. It offers excellent 
expandability up to 240TB with (120x 3.5” Nearline 
SAS drives) in 20U of rack space as well as a range 
of access port speeds to fit specific requirements. 
 
ETERNUS DX80 includes high availability features like 
Data Block Guard which adds an 8-byte check code 
to every 512 bytes of data to ensure enterprise-class 
data integrity. Redundant Copy rebuilds single disk 
drives at the earliest signs of failure. This 
dramatically reduces recovery time and minimizes 
the risk of permanent data loss. Fujitsu’s license-free 
encryption option prevents unauthorized access to 
confidential data wherever it is stored. All of these 
features, and the use of Eco-mode, mean the best in 
reliability and green storage in its class. 
 
ETERNUS DX80 is ideal for all kinds of system 
environments and supports three major host 
interfaces, Fibre Channel, SAS and iSCSI. It also 
meets the needs of different implementation sizes by 
offering a range of connection speeds: From four port 
1Gbit/s ISCSI (3.5” base model only) for up to 128 
servers, four port 3Gbit/s SAS (3.5” base model only) 
for up to 4 servers; to four ports of high-speed 
8/4/2/1 Gbit/s Fibre Channel (all models)) for 
connection to up to 128 servers. 
 
ETERNUS DX80 is delivered already equipped with 8 
backup snapshots and can be optionally upgraded to 
1024 snapshots..
