All plug-in modules and blank plates are part of the
fire enclosure and must be removed only when a
replacement can be added immediately. The system
must not be run without all parts in place.
4A system must be operated only from a power
supply input voltage range of 200–240 VAC,
50–60 Hz.
4A Data Domain system is intended to operate
with two working power supplies installed.
4Provide a suitable power source with electrical
overload protection.
4A safe electrical earth connection must be pro-
vided to the power cord. Check the grounding
of the power sources before applying power.
4The plug on each power supply cord is used
as the main disconnect device. Ensure that the
socket outlets are located near the equipment
and are easily accessible.
4Permanently unplug the unit if you think it is
damaged in any way and before moving it. If
the unit is powered by multiple sources, discon-
nect all supplied power for complete isolation.
4The power connections must always be
disconnected prior to removal or replacement
of a power supply module from any of the
components in the system. Standby power can
remain for several seconds, wait until all LEDs
are dark before proceeding.
4A faulty power supply module must be replaced
within 24 hours.
4Do not lift system components by yourself. A
system weighs 90 lbs (41 kg).
4To comply with applicable safety, emission,
and thermal requirements, covers must not
be removed and all bays must be fitted with
plug-in modules.
4Load the payload into the rack beginning at
the bottom to prevent the rack from becoming
top-heavy.
4Do not extend components on slide rails until
you have loaded at least three or more similarly
weighted items in the rack, or unless the rack
is bolted to the floor or overhead structure to
prevent tipping.
Warning: When the system is in normal use, the
system controller top cover must be secured with the
two Phillips captive screws provided at the front of the
system to prevent users or operators from accessing
the service areas.
Caution: If the system is used in a manner not
specified by the manufacturer, the protection provided
by the equipment may be impaired.
Caution: The RJ45 sockets on the motherboard/PCI
cards are for Ethernet connection only and must not be
connected to a telecommunications network.
ESD PRECAUTIONS
Data Domain recommends that you fit and check a
suitable anti-static wrist or ankle strap and observe
all conventional ESD precautions when handling
plug-in modules and components.
Safety
1. Unpack the Data Domain system. A system consists of a DD880g
controller that communicates with an external FC storage array. Up to
35.3 TB of external storage is supported by default. With the purchase
of a Gateway Expanded Storage Level 2 license, 71 TB of usable storage
is supported. The optional Gateway Expanded Storage Level 3 license,
introduced with DD OS 4.8, supports 143 TB of usable space.
A Data Domain gateway system needs to be 1) installed, 2) connected to
the external storage, and 3) configured to use this storage.
4Open the packing boxes for the system. Remove the accessories and
rack mount kits for all system components.
2. Install the appropriate rack mounting hardware for the system
into a 19-inch, four-post rack. Ensure that the rack is anchored to prevent
tipping. Load the rack or cabinet beginning at the bottom to prevent the
rack from becoming top-heavy. Be sure to plan appropriate vertical space
to accommodate the 4U system.
See the instructions included with the rack mounting kit.
3. Install the controller in the rack in a horizontal position.
4Remove the system and bezel from the shipping boxes.
4Install the Data Domain system on the corresponding slide rails and
slide in the rack. Be sure one person is at each side of the system to
guide it into the rail ends.
4Secure the system in the rack with the thumb screws.
4. Install the third-party external storage, following the instruc-
tions that accompanied the product.
5. Connect and configure storage. There are two connectivity
options: Fibre Channel direct-attached and Fibre Channel SAN-attached.
See the External Storage Configuration section.
Install Hardware

6. Connect an administrative console. Attach a serial console to the
controller’s serial port, or use KVM connections to connect monitor (VGA
port), keyboard and mouse. See Figure 1.
7. Enable data transfer connectivity. Repeat for each connection.
4Ethernet connection: To use 1 Gb copper Ethernet, attach a Cat
5e or Cat 6 copper Ethernet cable to an RJ45 Ethernet network port
(start with eth0 and go up) on the controller. Attach the other end
to an Ethernet switch or to an Ethernet port on your server. For 1 Gb
fiber Ethernet, use multimode fiber cables with LC connectors. For 10
Gb copper Ethernet with a CX4 connector, use an IEEE draft standard
802.3ak / D5.3 compliant cable or a Data Domain CX4 cable. Not all
CX4 cables qualify. For 10 Gb copper Ethernet with SFP+ connectors,
use a qualified SFP+ copper cable. For 10 Gb fiber Ethernet, use MMF-
850nm cables with LC duplex connectors. See Figure 1.
4Fibre Channel connection: Attach a Fibre Channel fiber optical cable
(LC connector) to a VTL HBA port on the system and attach the other
end (LC connector) to a Fibre Channel switch or to a Fibre Channel
port on your server. See Figure 1 for PCI slot locations for VTL cards.
8. Provide redundant power to the system. Connect power cables
to both receptacles and set the power cable tie wraps. See Figure 1.
9. Power on. Press the Power button. See Figure 2. Attach the bezel.
Note: Third-party SAN storage attached to the DD880g must be zoned if using
a Fibre Channel SAN before you power on the Data Domain system.
10. Collect the information needed for installation. Enter the
information in section 2, Define the Data Domain System Information for
Your Site, found on the other side.

ABOUT EXTERNAL STORAGE CONTROLLERS AND PORTS
4The storage array can have single or multiple controllers. Each controller
can have multiple ports.
4One storage controller port is required for each connection to the
gateway system.
4A SAN-attached storage controller port used for gateway connectivity
cannot be shared by other SAN-attached hosts that access the storage array.
4Optional redundant connectivity is supported. If you do not use redundant
connectivity, use the external array management interface to disable port
and controller failover.
ABOUT EXTERNAL ARRAY STORAGE
4External storage disks should be dedicated to the gateway and not shared
with other hosts.
4Disks should be configured into one or more LUNs and exported to the
gateway.
4A LUN should be configured using as many disks as possible.
4All disks in the LUNs must be identical drives and have identical RAID
configurations.
4The gateway can work with different RAID configurations, but the RAID
configurations that provide the fastest possible 256 KB sequential read
access should be used.
4A volume on the gateway system must have the same types of LUN but
the size can vary.
ABOUT GATEWAY LUN CONFIGURATION RULES
4A gateway system supports one volume composed of one to 112 LUNs.
LUN numbers must start at 0 (zero) but need not be contiguous.
4The maximum LUN number accepted by Data Domain gateway systems
is 255.
4The minimum data size for each LUN that a gateway system can access
is 400 GiB for initial install, some of which is not usable and reserved for
system use. For subsequent LUNs after the initial install, 100 GiB is the
minimum.
4Usable capacity will vary based on the storage configuration. The
maximum usable capacity for the gateway system is 143.48 TB, which
requires the Level 3 license.
4The maximum tested LUN size is 10 TB.
4To use the maximum amount of space on a system, create multiple LUNs
and adjust the LUN data sizes to comply with the defined rules. The “data
size” means the size of the LUN presented to the Data Domain gateway
system by the third-party external storage.
4The Data Domain spindle group feature allows LUNs to be mapped to
underlying disks contained in RAID groups. In general, configure a single
spindle group for each RAID group. For best use of this feature, use one
LUN per RAID group. There is a maximum of 16 spindle groups. For more
detail, refer to the Data Domain Command Reference Guide (disk add
dev command section).
CONNECT EXTERNAL STORAGE
The Data Domain gateway system can be directly attached to the External
Storage Array as in Figure 3, or SAN-attached using the Fibre Channel (FC)
as in Figure 4. A DD880g Gateway system has two dual-port FC Host Bus
Adapters (HBAs). The first HBA card port is located in PCI-e slot 2, and the
second in PCI-e slot 1 on the rear panel. See Figure 1.
Depending on your choice of connectivity, follow the appropriate connectivity
defined in the corresponding figures. For all connectivity, use a fiber optical
cable of appropriate length with an LC connector to connect to one of the FC
HBA card ports on the back of the Data Domain system (see 1in Figure 3 or
Figure 4). Connect the other end as noted in Figure 3 or Figure 4 (see 2in
the figures). If the system is SAN-attached, install the additional optical cables
from the FC switch to the appropriate ports on the external storage.
For availability of multipath failover functionality, consult with the Data
Domain Gateway Compatibility Matrix on the Data Domain Support web site.
Figure 3: Direct-Attached Configuration
Figure 4: SAN-Attached Configuration
CREATE LUNS
4On the external storage array, create the LUNs for use by the Data Domain
gateway system. Instructions for creating LUNs are specific to your third-
party storage. See the Installation Guide on the Data Domain Support
web site under Integration Documentation.
4On the external storage array, configure LUN masking so that the Data
Domain gateway system can see only those LUNs that should be available
to the Data Domain gateway system.
SAN ZONE CONFIGURATION
When the storage is SAN attached, create a single initiator zone that includes
one port of the DD880g and the corresponding ports of the storage. Create
separate zones for each path of the DD880g.
For example:
Zone 1
---------
DD880g_p1a
STORAGE_p0
STORAGE_p0_p1
Zone 2
---------
DD880g_p2a
STORAGE_p0_p0
STORAGE_p0_p1
Consult information in the SANs Integration Documentation and
Compatibility Matrices on the Data Domain Support web site.

NOTE: The system might not be usable for up to three hours if the NVRAM batteries
are discharged. Refer to the NVRAM Battery Charging Instructions for more
information.
Log into the system with the user name of sysadmin. The password is the
system’s serial number. A Configuration Wizard is provided. There are six
sections to the configuration: Licenses, Network, File System, System, CIFS,
and NFS.
Complete each of the six sections.
USING THE CLI CONFIGURATION WIZARD
At the first login, the configuration utility starts. The list entries in the utility
can be comma-separated, space-separated, or both.
4At each prompt, enter a value, OR
4Enter a question mark (?) for more details, OR
4Press Enter to accept the value displayed in braces.
The Configuration Wizard guides you through the configuration steps, one
section at a time. Follow the Configuration Wizard instructions for entering
appropriate values.
At the end of each configuration section, you can choose to:
4Save – Save the displayed configuration.
4Cancel – Delete all new values and go to the next section.
4Retry – Restart the input entry at the beginning of the current section.
The value entered previously appears as the default value at each prompt.
CONFIGURE THE LUNS
4Use the disk show hardware command to determine the size of
each LUN.
4To find out which LUNs are available, use the disk show raid-info
command.
4Use the disk rescan command to discover the LUNs provisioned
from the storage array.
4Use the disk add devdisk_id command to add a LUN to the current
volume. You can add only LUNs with a status of unknown—not already
added to the Data Domain file system.
For more information, see the DD OS Command Reference Guide (disk add
dev command section).
4To assign a LUN group to the disk, use this command:
disk set devdisk_id spindle-group 1-16
where the spindle group is identified as a number (1 through 16).
4There is a maximum of 16 spindle groups. The simplest way to configure
LUNs is to use the same number for both the device and the spindle
group. For example:
# disk add dev2 spindle-group 2

Troubleshooting Tips
If you purchased optional software for the Data Domain system such as
Replicator or Retention Lock, the licenses are enabled on your Data Domain
system prior to shipment. You need to configure them for use. Details
configuring the optional software can be found in the DD OS Administration
Guide. Access the latest documents at
https://my.datadomain.com/US/en/platform.jsp.
Configure Optional Software
5
The Data Domain system provides multiple protocols for data access: NFS,
CIFS, VTL, and OST (OpenStorage). You need to configure one or more
protocols for data access, depending on your environment. You also need to
configure the clients for accessing the Data Domain system with the protocol
of your choice.
NFS
The NFS configuration section in the Perform Initial System Configuration sec-
tion sets up the NFS clients to allow access to /backup on the Data Domain
system. You also need to set up the NFS clients to allow access to /backup on
the Data Domain system. This can be done using the following steps:
4Create a mount point (directory) such as /dd/rstr01/backup, and
create an administrative mount point, such as /dd/rstr01/ddvar.
4NFS mount the directories on the new mount points. For example:
mount -F nfs -o hard,intr,vers=3,proto=tcp,rsize=327
68,wsize=32768 rstr01:/backup /dd/rstr01/backup
mount -F nfs -o hard,intr,vers=3,proto=tcp,rsize=327
68,wsize=32768 rstr01:/ddvar /dd/rstr01/ddvar
4Add the following lines to the file /etc/vfstab (the file name may be
different depending on your UNIX-based system). The lines mount the
directories at every reboot. For example:
system:/backup - /dd/rstr01/backup nfs - yes
hard,intr,vers=3,proto=tcp, rsize=32768,wsize=32768
system:/ddvar - /dd/rstr01/ddvar nfs - yes
hard,intr,vers=3,proto=tcp, rsize=32768,wsize=32768
4To cause backup software to abort when the system is not mounted,
create a backup directory within the mounted file system, such as
/dd/rstr01/backup/disk1.
4For more configuration information, see the specific Data Domain Integration
Documentation at https://my.datadomain.com/US/en/integration.jsp.
CIFS
The CIFS configuration section in the Perform Initial System Configuration sec-
tion sets up the CIFS clients to allow access to /backup on the Data Domain
system. You also need to set up the CIFS clients to allow access to /backup
on the Data Domain system. For additional configuration information, see the
specific Data Domain Integration Documentation at
https://my.datadomain.com/US/en/integration.jsp.
VTL (OPTIONAL LICENSE REQUIRED)
For the VTL software option, see the Data Domain technical note Integrating
the Data Domain Appliance VTL with SANs. See the specific Data Domain
Integration Documentation for setting up backup software from other
vendors: https://my.datadomain.com/US/en/integration.jsp.
OPENSTORAGE (OPTIONAL LICENSE REQUIRED)
For setting up the Data Domain OST feature, see the Data Domain
OpenStorage (OST) Administration Guide available at
https://my.datadomain.com/US/en/platform.jsp.
APPLICATION INTEGRATION
For information about how to integrate the Data Domain system with backup
software, see the documentation for the applicable application at the Data
