2.5" disk or 2.5" Solid State Drive (SSD)

Hardware Configurations

This chapter explains hardware configurations for the ETERNUS DX Disk storage system.

1.1 Controller Enclosure

This section explains the main components in the controller enclosure.

The controller enclosure contains drives installed in the front, and controllers and power supply units in the
rear.
Since the power supply units are redundant, operations can continue even if one of them fails. There are two
models: a single-controller type and a dual-controller type. For a dual-controller type, operations can continue
even if one of the controllers fails.

• The single-controller type differs from the dual-controller type by the following features:

- The controller and I/O module are not duplicated.

- Hot maintenance or swapping of the controller and I/O module is not possible.

- Concurrent firmware loading or update of the controller firmware and I/O module firmware is not

possible.

- Multipath connection to a single server is not available.

- The Thin Provisioning function cannot be used.

- The Flexible Tier function cannot be used.

• Fujitsu recommends that the dual-controller types, in which the controller and I/O module are duplicated,

be used in a system where a high level of reliability is required.

1.1.1 Controllers

The controller contains a CPU, cache memory, System Capacitor Unit (SCU), non-volatile memory, host
interfaces, drive interface ports, and LAN ports. The controller controls all operations in the ETERNUS DX Disk
storage system.

■ CPU

A single core processor is installed.

■ Cache memory

Cache memory enables high speed processing by storing frequently used data.
The cache memory capacity for each controller is 2GB for the ETERNUS DX80 S2 and 4GB for the ETERNUS DX90
S2.

Chapter 1 Hardware Configurations

1.1 Controller Enclosure

■ Host interfaces

A host interface (CA) is a board that has interface ports to connect a controller to a server.
Up to two host interfaces can be installed in the controller of an ETERNUS DX Disk storage system. Different
types of host interfaces can exist together in the same controller. For details about the installation rules, refer
to "4.3.1 Host Interfaces" (page 70)
FC, iSCSI, FCoE, and SAS are available as host interface.

The following table shows the host interface specifications.

Table 1.1 Host interface specifications

• FC and iSCSI host interfaces can be used as remote interfaces for remote connections by changing the port

mode. The port mode can be set from ETERNUS Web GUI or ETERNUS CLI.

• There are two types of iSCSI 10Gbit/s and FCoE host interfaces; an interface type with SFP+ modules (LC

connector for an FC cable connection) and an interface type without SFP+ modules (SPF+ connector for a
Copper Twinax cable connection).

• For SFP+ modules, Short Wave Length (SWL) or Long Wave Length (LWL) types can be installed in

16Gbit/s FC interfaces. The default modules that are installed in 16Gbit/s FC interfaces are SWL type SFP+
modules. To install LWL type SFP+ modules, purchase the Long wave SFP+ modules for the DX80 S2/DX90
S2 separately.

■ Drive interface ports

A drive interface port is used to connect drive enclosures.
The following table shows the drive interface port specifications.

■ LAN ports

Two LAN ports (RJ-45) are installed in each controller.
Each LAN port is used for operation management (MNT port) and for remote support function (RMT port)
respectively.

The following table shows the LAN port specifications.

■ SCU

A System Capacitor Unit (SCU) is installed in a controller as a backup power source in case of power outage.
The SCU is charged from an external power source while the ETERNUS DX Disk storage system is running nor­mally. If a power failure is detected, data in the cache memory is saved to the non-volatile memory in the con­troller using the SCU. There is no limit to the post-failure data retention time.

■ PWC ports

A PWC port is installed in a controller.
The PWC port is used to connect a power synchronized unit to perform power synchronization.

The following table shows the PWC port specifications.

Table 1.4 PWC port specifications

1.1.2 Power Supply Units

The power supply unit transforms input AC power from a power socket to DC power and supplies power to each
component. Two power supply units are installed in each controller enclosure.
Each power supply unit contains fans.

1.2 Drive Enclosures

This section explains the main components in the drive enclosure.
The drive enclosure contains drives installed in the front, and I/O modules and power supply units in the rear.
Up to 24 drives can be installed in a 2.5" type drive enclosure. Up to 12 drives can be installed in a 3.5" type
drive enclosure.
Since the power supply units are redundant, operations can continue even if one of them fails.
When a drive enclosure is connected, a DE-ID (drive enclosure number) is automatically allocated.

1.2.1 I/O Modules

The I/O module is a component that controls the interaction between the controller and the drives.
The I/O module is connected to the controller or an I/O module on another drive enclosure.

■ Drive interface ports

A drive interface port is used to connect a controller enclosure or drive enclosures.
The drive interface port has an IN port and an OUT port.
The following table shows the drive interface port specifications.

1.2.2 Power Supply Units

The power supply unit transforms input AC power from a power socket to DC power and supplies power to each
component. Two power supply units are installed in each drive enclosure.
Each power supply unit contains fans.

1.3 Enclosure Connection Path

For a dual-controller type, a controller enclosure (CE) is connected to drive enclosures (DE) with multiple
paths.
A drive enclosure has two independent drive interface ports. Path redundancy is maintained by connecting
the drive enclosure to two controllers directly. This configuration allows operation to continue even if one of
the connection paths fails.

Up to nine drive enclosures can be connected to a controller enclosure as shown in the figures below.

–

There are two sizes for power distribution units: 1U and 2U.
A power distribution unit is an option to connect power supply units to power outlets when power sockets are
limited.

connection)

There are four outlets and two inlets.
