With three different base models, ETERNUS DX80 entry level disk storage systems can either
connect to hosts via Fibre Channel (with 8 Gbit/s performance option), iSCSI or SAS. They are
easy to install, configure, operate and maintain, integrating well with host operating systems,
servers, network infrastructures and backup solutions.
Different drive types can be mixed and matched, secured by the relevant monitored RAID
levels (0, 1, 1+0, 5, 5+0 and 6) and features to ensure data integrity. Administrators can
dynamically move data, spin disks down to save energy or encrypt data to prevent
unauthorized access.
In the event of power outages, the content of the cache is secured to flash memory. A backup
copy is always at hand via snapshots and clones.

Main features
Benefits
Redundant RAID controllers, fans and power supplies that are
hot swappable
Cache Protector uses capacitor technology to better protect
RAID controller cache during power outages
Redundant Copy rebuilds a disk automatically as soon as the
first signs of failure appear
Data Block Guard appends check codes to every data block and
verifies them at multiple checkpoints.
RAID Migration enables LUNs to be moved dynamically between
different RAID groups and hard disks without interrupting
operations
Mixed SAS, Nearline SAS disk drives and SSD
Eco-mode spins down disk drives

For highest 99.99% availability
Returns the array to high performance mode within
minutes following restore
Dramatically reduces recovery times and minimizes the
risk of permanent data loss during recovery
Helps to ensure maximum data integrity on disk in cache
and in between
Allows different service levels to be provided matched to
access frequency and data importance
Fulfills all main performance and capacity requirements
Reduces energy consumption and heat dissipation
