Storage CapacityTable 2 lists the capacities of the DD660, DD690, and DD690g. Data Domain system internal indexes and other product components use variable amounts of storage, depending on the type of data and the sizes of files. If you send different data sets to otherwise identical systems, one system may, over time, have room for more or less actual backup data than another.

Note: Data Domain system commands compute and display amounts of disk space or data as decimal multiples of certain powers of two (210, 220, 230, and so forth). For example, 7 GiB of disk space = 7 x 230 bytes = 7 x 1,073,741,824 bytes. Data Domain refers to this process as Base 2 calculation.

Note: For information about the Data Domain ES20 expansion shelf, see the separate document Data Domain Expansion Shelf Hardware Guide.

Front Control PanelThe control panel is at the left edge of the front panel (see Figure 1).

Figure 1: Control panel switches and LED indicators

The control panel contains the following switches, from top to bottom:

The front of the control panel contains a mini-USB socket and the following LED indicators, from top to bottom:

Power Button Press to start boot (if not running). Use the system poweroff command to shut down the system.

System Reset Do not press system reset unless Data Domain Technical Support instructs you to do so. Pressing system reset causes the system to reboot immediately.

ID Enclosure Button

Press the ID switch to light the blue ID LEDs on the front and back panels. When working with a large number of rack mounted units, all of similar appearance, use the ID LEDs to keep track of which unit you are working on. The ID switch also silences the audible alarm if the alarm is sounding.

Power Active The power active LED glows green when the device is on.

Unit Fault Display Meaning Possible Causes

Slow blink Warning Temperature near the alarm threshold (hot or cold)Fan failureDrive fault (if the drive fault light also illuminates)

Fast blink Warning Temperature alarm (hot or cold)Multiple fan failuresPower supply failure

Steady amber

Fault Temperature exceeds threshold (hot or cold)Power supply failure

ID LED The ID LED and its mate on the back panel glow blue after you press the switch to toggle them on. They stay blue until you press the switch again to toggle them off.


Back PanelThe back panel has the following major functional areas (see Figure 2):

• Power Supply Units

• Hardware Interface Panel

• System card interfaces (see “PCI Cards and Slot Assignments” on page 11)

Figure 2: Back panel

Power Supply UnitsA system has two power supply units. Each power unit has a bi-color LED (green or amber).

• Green LED

A steady green LED indicates that the unit is functional and powered on.

A flashing green LED means that Data Domain system is turned off, and the unit has valid AC power but is waiting for the system power-on button to be pressed.

• Amber LED

An amber LED indicates a power supply fault. Most classes of PSU faults are indicated by a steady amber condition.

A flashing amber LED means that the power supply is experiencing an over-voltage, under-voltage, or over-current fault condition. The source of this condition could be due to AC input power, a chassis fault, or a power supply module fault.

Hardware Interface PanelThe hardware interface panel (see Figure 3) enables you to connect to the system through a serial console, monitor, and keyboard, or through an Ethernet connection.

The Ethernet interfaces are for data transfer to the Data Domain system or for administrative access over a network. Both Ethernet interfaces are 1000 Base-T Gigabit copper ports with RJ45 connectors that can accept 10/100 Base-T or Gigabit connections. The four USB ports below the Ethernet ports are not used.

Each Ethernet connection has two LEDs, one on each side of the connector. The left LED is the Link/Activity LED. When it is dark, the port has no live connection. It glows green when a link is established and flashes green with transmit/receive traffic. The right LED is the Speed LED. It indicates 1Gps when amber, 100 Mbps when green, and 10 Mbps when off.

Figure 3: Hardware Interface Panel

The Ethernet ports are named in one of the following ways:

• eth0 and eth1 (legacy port naming)

• eth0a and eth0b (slot-based port naming)

For more information about Ethernet port naming, see “Ethernet Card Options and Port Naming” on page 12.

Internal System ComponentsFigure 4 shows the location of system components behind the center fans. The PCI card array is in the back left corner of the chassis when viewed from the front of the system

Figure 4: Top View (Cover Removed)


PCI Cards and Slot AssignmentsThe system card interface area gives access to the cards in the internal PCI card array. See Figure 2 for a view of the slot positions on the back panel. Slot 6 is on the left, when viewed from the rear of the chassis.

The system card interface area supports the following low profile PCI options:

• The 1024 MB NVRAM card

• Serial-attached SCSI (SAS) HBA cards for expansion shelves connectivity on the DD690 and DD660 or dual-port 4-Gb Fibre Channel HBA cards for third-party storage connectivity on the DD690g

• Optional network interface (NIC) cards

• Optional dual-port 4-Gb Fibre Channel host bus adapter (HBA) cards for the VTL feature

Table 3 and Table 4 show the PCI card slot assignments for the systems.

All systems have one NVRAM card.

A DD660 or DD690 system has two dual-port Serial Attached SCSI (SAS) HBA PCIe cards for expansion shelf connectivity. Each SAS HBA port accepts a miniSAS connector.

A DD690g system has two dual-port 4-Gb Fibre Channel PCIe HBA cards for third-party storage connectivity. Each port accepts an LC connector.

All systems have two slots available for optional Ethernet NIC and VTL HBA cards. The optional VTL feature requires at least one VTL HBA card. Depending on your needs, you can leave these slots empty, install two cards of either type, or install one card of each type.

VTL Card Option

The VTL card is a dual-port 4-Gb Fibre Channel PCIe HBA card. Up to two VTL cards can be installed in a DD660, DD690, or DD690g system.

Ethernet Card Options and Port Naming

These systems support up to two of the following optional 1-Gb or 10-Gb Ethernet PCIe NICs:

• Dual-port optical 1-Gb (1000 Base-SX) multi-mode fiber Ethernet PCIe NIC with LC connectors

• Dual-port copper 1-Gb (1000 Base-T) Ethernet PCIe NIC with RJ45 connectors

• Dual-port copper 10-Gb (10GBase-CX4) Ethernet PCIe NIC with CX4 connectors (requires DD OS 4.5 or later)

• Single-port optical 10-Gb (10GBase-SX) multi-mode fiber (850 nm) Ethernet PCIe NIC with an LC connector (requires DD OS 4.6 or later)

• Dual-port copper 10-Gb Ethernet PCIe NIC with SFP+ connectors (requires DD OS 4.9 or later)

• Dual-port optical 10-Gb Ethernet PCIe NIC with LC connectors (requires DD OS 4.9 or later)

Note: Two of the same card type can be installed, or a combination of two different card types. Certain restrictions apply to combinations of the listed 10-Gb NICs in a system. The following combinations are supported:

• Dual-port copper 10-Gb Ethernet PCIe NIC with SFP+ connectors plus Dual-port optical 10-Gb NIC with LC connectors

Both cards require DDOS 4.9 or later.

• Dual-port copper 10-Gb Ethernet PCIe NIC with CX4 connectorsplusSingle-port optical 10-Gb (10GBase-SX) Ethernet PCIe NIC with an LC connector.

Other combinations of 10-Gb NICs are not supported.

The Ethernet ports on the system motherboard are named in one of the following ways:

• eth0 and eth1 (legacy port naming)

• eth0a and eth0b (slot-based port naming)

Legacy port naming is used on systems that are running DD OS 4.8 and earlier software versions. In addition, systems that are upgraded to DD OS 4.9 will continue to use legacy port naming unless you explicitly configure slot-based port naming after the software upgrade.

Slot-based port naming occurs by default in systems with a fresh installation of DD OS 4.9, or in new systems that are shipped with DD OS 4.9 installed. With slot-based port naming, the Ethernet ports on installed optional Ethernet cards are identified by a combination of their slot number and port letter. The first port in a slot (at the top of the card) is labeled a and the second port is b. For example, a dual-port copper card in Slot 6 has the Ethernet port names eth6a and eth6b.
