QUALITY AND RELIABILITY
ETERNUS DX80 offers non-stop robustness and redundant hot-pluggable
components such as power supplies, fans, and RAID controllers.
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
during such recovery. 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.
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 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
SAN environments. 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 GUI or 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” format, ETERNUS DX80
flexibly scales from 600GB to 240TB. An alternative FC base model is available
for up to 24x 2.5” drives. With 2.5” 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.
