Table 2 lists the capacities of the DD670, DD860, and DD890 systems. 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.

Front Control Panel

The control panel is at the right edge of the front panel. The control panel contains the
following switches and LED, from top to bottom:

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

ID Enclosure Button Press the ID switch to light the blue ID LEDs on the front and back panels.

System Fault LED This LED illuminates in green or amber to report a system fault.

to shut down the system. Never shut down the system by pressing the
power button. The button glows steady green in the normal operating
state, and blinks to indicate that the system is in a power-saving state.

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 button glows steady blue after being pressed or after activation by
a system command. A system command can also cause the button to blink
while the system is under service.

The system needs to be shut down and serviced.
Causes include hardware errors and critical
overheating.

The system is reporting a non-fatal problem that
requires service. Possible causes include:

• Overheating warning

• Overvoltage warning

• Single fan failure

• Power Supply or AC failure

• PCIe link degraded

• SAS interface degraded

• Disk drive failure

• Other system-identified problems

DD670, DD860, and DD890 Hardware Overview 7

Back Panel

The back panel has the following major functional areas (see Figure 1):

• Power Supply Units

• Hardware Interfaces

• System card interfaces (see “PCI Cards and Slot Assignments” on page 9)

Figure 1: Back Panel

A sticker on the back panel (not shown in Figure 1) shows the system MAC address.

Power Supply Units

The systems have two power supply units. Each power unit has an LED that glows green
when the unit is functional. The LED glows amber if the unit has failed, but still has
power. The LED blinks amber if the power supply does not have AC power. The LED
flashes green when the Data Domain system is turned off but the unit is still plugged in
to a live power source. The LED is dark if the unit has no power.

The two power cords, plugged into the power supply outlets, are held in place by use of
cable restraint ties attached to each power supply.

Hardware Interfaces

The hardware interfaces (see Figure 2) enable you to connect to the system through a
serial console, monitor, and keyboard, or through an Ethernet connection.

The pair of Ethernet interfaces at the left—eth0a and eth0b—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 single 10/100 Base-T Ethernet port to the right
of the pair of Ethernet ports is used for system maintenance only.

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 1 Gbps when amber, 100 Mbps when green, and 10 Mbps
when off.

The four USB ports, keyboard port, mouse port, VGA port, and serial port are not used
during normal operation. They may be used while the system is being serviced. The SAS
JBOD connector is never used.

PCI Cards and Slot Assignments

The system supports the following required and optional PCI cards:

• The 1024 MB NVRAM card

Note: The NVRAM card for the the DD670 and DD860 is different than for the DD890

system.

• Serial attached SCSI (SAS) HBA cards for expansion shelves connectivity

• Optional network interface (NIC) cards

• Optional dual-port 8Gb Fibre Channel host bus adapter (HBA) cards for the VTL

feature

Standard PCI Cards

All DD670 and DD860 systems have one NVRAM card. The DD890 system has two
NVRAM cards.

Note: The NVRAM cards used in the DD890 system are different than the card that is

used in the DD670 and DD860 systems.

The DD670 system optionally has two quad-port Serial Attached SCSI (SAS) HBA PCIe
cards for expansion shelf connectivity. The DD860 and DD890 systems have two fixed
SAS cards. The DD860 Archiver system has 3 fixed SAS cards. Each SAS HBA port
accepts a mini SAS connector.

VTL and Ethernet Card Options

The DD670 and DD860 systems have three slots available for optional Ethernet NIC and
VTL HBA cards. The DD860 Archiver option and the DD890 system 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 or install up to three Ethernet cards, up to two VTL cards, or any combination of
Ethernet cards and up to two VTL cards.

The VTL HBA card is a dual-port 8 Gbps VTL Fibre Channel PCIe card.

The available Ethernet NIC cards are:

• Dual port copper 1Gb (1000 Base) Ethernet PCIe NIC with RJ-45 connectors (DD670

system only)

• Quad port copper 1Gb (1000 Base) Ethernet PCIe NIC with RJ-45 connectors

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

connectors

• Dual port copper 10 Gb Ethernet PCIe NIC with SFP+ connectors

• Dual port optical 10 Gb Ethernet PCIe NIC with LC connectors
