QUALITY AND RELIABILITY
ETERNUS DX80 offers non-stop robustness and redundant hot-pluggable
components such as power supplies, fans, and RAID controllers.
Different drive sizes and types can be mixed and matched. All the relevant RAID
levels (0, 1, 1+0, 5, 5+0 and 6) are available so that data can be protected in a
flexible manner to meet reliability and security requirements. Furthermore, the
RAID Migration feature can be used to dynamically move data between different
RAID groups and drives without interrupting operations. This allows data to be
moved to fast SAS disk drives or high-capacity Nearline SAS disk drives
according to its access frequency and importance.
With the ever increasing capacities of Nearline SAS disk drives, recovery times
when a drive fails are extending. This increases the risk that another drive will fail
and the data cannot be recovered. It can take a number of days to rebuild a 2
terabyte disk drive in a RAID 5 configuration. "Redundant Copy” starts the rebuild
procedure as soon as the first signs of failure appear. This dramatically minimizes
the risk of permanent data loss during the recovery action.
ETERNUS DX80 protects data on the disk drives not only via RAID but also via the
Data Block Guard. This function appends a check code to every data block and
verifies it at multiple checkpoints. This improves data integrity both on the drives
and in the cache. Should data corruption occur, the system can detect and rectify
the error to guarantee the consistency of all stored data.
Using Data Encryption, no unauthorized access is possible when drives are
removed from the storage system. This feature can be activated if required and is
only available in countries where encryption of data is permitted.
ETERNUS DX80 is also equipped with state-of-the-art Cache Protector. Instead of
traditional batteries, it uses capacitors to write the contents of the RAID controller
cache to flash memory in the event of a power failure. This means lengthy power
failures can be "survived". The power generated by the capacitor is sufficient for
the data backup. When power supply is restored, the cache can be restored very
quickly as capacitors recharge a lot faster than batteries. The capacitors used in
ETERNUS DX80 do not need as much maintenance and have a longer lifespan
than batteries frequently used in other systems.

INNOVATION AND FLEXIBILITY
With three interface models, ETERNUS DX80 can connect to hosts via Fibre
Channel, iSCSI or SAS, using either single or dual controllers with 2GB of each
cache. Online upgrades from single to dual controller configurations are possible.
With two Fibre Channel controllers, a maximum of 128 hosts can be connected in
Storage Area Networks (SAN). In contrast, the iSCSI models enable SAN
functionality via the well-known Internet Protocol which requires no investment in
new IT infrastructure and training, making it very suitable for small businesses. In
comparison, the SAS models directly connect to servers so that very low-priced
cluster configurations can be implemented.
With the Advanced Copy functions, a business data volume can be copied to a
separate copy volume within the disk storage system, at any point in time. Once
the copy is completed, the copy volume can be separated from the business
volume. This allows easy backup to a tape device, as using the point in time copy
allows normal operations on the business data to continue.

ETERNUS DX80 is equipped with 8 snapshot sessions. Using the Graphical User
Interface (GUI) or Command Line Interface (CLI), they enable planning of the
required quantity of copy sessions as well as testing of functions. Once a copy
license is purchased, snapshots can be extended to 1024 sessions.
ETERNUS DX80 is a leading energy-efficient storage system. In Eco-mode, which
uses MAID (Massive Array of Idle Disks) technology, it requires even less energy
and produces less heat as disk drives not in use can be shutdown. In
backup-to-disk environments, drives used for nightly backup can be spun down
during daily operations. This contributes significantly to system and data center
efficiency.

EASE-OF-USE
Installation is quite simple. The management software - with its graphical user
interface and installation wizard - is designed for easy intuitive operation and
comes pre-installed on each system. Day to day operation management of
ETERNUS DX80 is very straight forward. Firmware upgrades can also be carried
out - usually without any operational interruptions.
With ETERNUS SF Express already bundled for simplified storage system
management and maintenance, this same software assists in monitoring multiple
ETERNUS DX disk storage systems from the one centralized console. In addition it
manages the Advanced Copy functions within the storage system making
snapshots and clones an easy task, through one combined management console.

VERSATILITY AND INTEROPERABILITY
At just 2U height and with a capacity of 12 drives in 3.5 inch format, ETERNUS
DX80 flexibly scales from 600GB to 240TB. An alternative FC base model is
available for up to 24x 2.5 inch drives. With 2.5 inch drives the maximum storage
capacity of each system is limited to 36 Terabytes.
ETERNUS DX80 is suitable for a broad range of uses, including high-availability
solutions. Examples are: Microsoft Cluster Server, x10sure or ServerView
Resource Coordinator VE, storage consolidation, critical company applications,
such as databases or e-mail, archiving and backup-to-disk. ETERNUS DX80 is
also ideal for use in the virtual server environments of VMware vSphere, Citrix and
Microsoft Hyper-V.
