Chapter 1
Overview
This chapter provides an overview and describes the features of the ETERNUS DX Disk storage system.
Figure 1.1 External view
■Scalability
●Unit size
The base unit size is 2U (*1). 2.5" type (24 drives for each enclosure) and 3.5" type (12 drives for each
enclosure) are available.
*1: 2U is the height for a device that can be installed in two 19-inch rack units (1U = 44.45mm).
●Drives
The ETERNUS DX Disk storage system supports high performance online disks (*2), cost effective Nearline
disks with large amounts of capacity (*3), and SSDs that provide super-fast access.
Up to 120 drives can be installed in the ETERNUS DX80 S2. Up to 240 drives can be installed in the ETERNUS
DX90 S2. 2.5" drives and 3.5" drives can be installed together in the same ETERNUS DX Disk storage system.
*2: Disks with high performance and high reliability for accessing data frequently. SAS disks are provided as online
disks.
*3: Disks with high capacity and high reliability for data backup. Nearline SAS disks are provided as Nearline disks.
●Host interfaces
Host interfaces can be selected from FC 16Gbit/s, FC 8Gbit/s, iSCSI 10Gbit/s, iSCSI 1Gbit/s, FCoE 10Gbit/s,
and SAS 6Gbit/s. Up to eight ports can be installed in a single ETERNUS DX Disk storage system. Different
types of host interfaces can exist together in the same ETERNUS DX Disk storage system.
●Cache capacity
The maximum capacity of cache memory that can be installed in a single ETERNUS DX80 S2 is 4GB. The
maximum capacity of cache memory that can be installed in a single ETERNUS DX90 S2 is 8GB.

●Model upgrade
As a support for system scalability after installation, an ETERNUS DX Disk storage system can be upgraded
to a higher-end model. The ETERNUS DX80 S2 can be upgraded to the ETERNUS DX90 S2. The ETERNUS
DX80 S2/DX90 S2 can be upgraded to the ETERNUS DX410 S2/DX440 S2.
■High reliability
●RAID levels
The ETERNUS DX Disk storage system supports RAID5+0 that is superior to RAID5 in reliability and
performance, and RAID6 that responds to the double failure of disks, as well as RAID1, RAID1+0, and
RAID5.
●Redundant configurations
Important components are duplicated to maintain high fault tolerance. This allows hot swapping of failed
components without interrupting operations.
●Data protection against power failure
Since data is saved from the cache memory to the non-volatile memory in the controller when a power
failure occurs, data can be retained indefinitely.
●Data integrity
The ETERNUS DX Disk storage system adds check codes to all data that is saved. The data is verified at
multiple checkpoints on transmission paths to ensure data integrity.
●Monitoring for signs of failure
When a possible sign of drive failure is detected, the data of the suspect drive is restored to the hot spare
and the suspect drive is switched while maintaining data redundancy.
●Data Encryption
The ETERNUS DX Disk storage system has the ability to encrypt data as it is being written. Encryption with
firmware is supported by default. Together with the world standard 128bit AES method (*4), Fujitsu's own
high performance encryption method is also supported.
In addition, Self Encrypting Drives (SEDs) are available. Since each drive performs self encryption instead
of the firmware, loads that are usually caused by encryption using firmware are removed and data can be
encrypted without reducing performance. SEDs use the 256bit AES method. An SED authentication key can
be stored in the ETERNUS DX Disk storage system and the key server.
*4: Advanced Encryption Standard: Federal Information Processing Standards method

■Operability
●Easy operation management
Operation management can be easily performed with ETERNUS Web GUI by using a Web browser or with
ETERNUS CLI by using commands and command scripts.
●Virtualized environment integration
Various functions that are provided by Oracle VM, VMware, and Microsoft are supported to configure and
operate virtualized environments.
A more effective use of resources and the integrated management of virtualized environments can be
achieved by offloading the server load to the ETERNUS DX Disk storage system in collaboration with
servers.
●Storage virtualization
Virtualization technology enables a larger capacity than the physical disk capacity to be shown to the
server. Multiple physical disks are collectively managed as a disk pool and the necessary capacity is flexibly
allocated according to write requests from the server.
The ETERNUS DX Disk storage system has a function that balances writing areas on a volume basis to
prevent concentrated access to a specific RAID group in multiple RAID groups that configure a disk pool.
●Automatic layering
The ETERNUS DX Disk storage system supports automatic storage layering. This function detects data
access frequency and redistributes data between drives with various drive types according to the policy
that is set. The most suitable cost effective performance can be realized by moving frequently accessed
data to high performance SSDs and less frequently accessed data to cost effective Nearline disks in
collaboration with ETERNUS SF Storage Cruiser. Server settings do not need to be changed after
redistribution.
●Connectivity
OSes such as UNIX, Linux, Windows, and VMware are supported. The ETERNUS DX Disk storage system can
be connected to various UNIX servers and industry standard servers by Non-Fujitsu manufacturers as well
as Fujitsu servers such as PRIMEQUEST and PRIMERGY.
●Backup
Data can be replicated at any point with high speed by using the Advanced Copy functions in conjunction
with software such as ETERNUS SF Advanced Copy Manager.
Data can be replicated between multiple ETERNUS DX Disk storage systems without affecting the
performance of the server by using the remote copy functions.
●Stabilization of processing performance
When loads from one application are high in a storage integrated environment and sufficient resources to
process other operations cannot be secured, performance may be reduced remarkably.
The QoS (*5) function can be used to stabilize performance by setting the load upper limit for each
application to secure the processing performance of the server that needs to be processed preferentially so
that workload fluctuations do not affect other applications.
*5: Quality of Service

●ETERNUS SF Express
ETERNUS SF Express is a storage system introduction and operation support software for the user who had
put off the introduction of the storage system up to now because of "Difficulty" and "Introduction and
operation cost increase". ETERNUS SF Express is an easy to use software addition to the ETERNUS DX Disk
storage system, facilitating management of the ETERNUS DX Disk storage system and leveraging the
ETERNUS DX Disk storage system functionality such as Snapshots, Cloning, or Replication.
■Environmental friendliness
●Power efficiency
The Eco-mode function, which is compatible with Massive Arrays of Idle Disks (MAID), manages the
schedule for drive operation times.
Drive motors that are not scheduled to run are stopped in order to reduce power consumption.
●RoHS compliance
The ETERNUS DX Disk storage system complies with RoHS, as mandated by the European
Parliament and Council. RoHS limits the use in electric and electronic equipment of six specific
chemicals: lead, hexavalent chromium, mercury, cadmium, polybrominated biphenyl (PBB), and
polybrominated diphenyl ether (PBDE). In addition, lead-free soldering is used for all printed-wiring
boards.

2.1.2 ETERNUS DX90 S2 Specifications
Table 2.2 ETERNUS DX90 S2 specifications
*1: Physical capacity is calculated based on the assumption that 1TB=1,000GB and 1GB=1,000MB.
*2: Logical capacity is calculated based on the assumption that 1TB=1,024GB, 1GB=1,024MB and that drives are
formatted in a RAID5 configuration. The available capacity depends on the RAID configuration.
*3: 3.5" type and 2.5" type drive enclosures can be installed together.
*4: Two ports for each controller
*5: One port for each controller. Power synchronization is performed via a power synchronized unit.
