Data Domain DD690g Istruzioni per il montaggio
Installation and Setup Guide
DATA DOMAIN DD690g GATEWAY SYSTEM
1. Unpack the Data Domain system. A system consists of a DD690g
controller that communicates with the external disk array. Up to 35.5 TB
of external usable storage is supported.
A Data Domain gateway system needs to be 1) installed, 2) connected to
the external storage, and 3) configured to use this storage.
4Open the packing boxes for the system.
4Remove 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 2U system.
4See the instructions included with the slide rails. See Figure 1.
3. Install the controller in the rack in a horizontal position.
4Remove the system from the shipping boxes.
4Remove the bezel from the Data Domain system.
4Install 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.
4Secure 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.
6. Connect an administrative console. Attach a 9-pin serial console
to the controller’s serial port, or attach a Cat 5e or Cat 6 Ethernet cable
to an Ethernet port (DHCP required), or use a monitor (VGA port) and
keyboard (keyboard/purple icon), or use KVM. See Figure 2.
7. Enable data transfer connectivity. Repeat for each connection.
4Ethernet connection: If using 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 system, and attach the other end
to an Ethernet switch or to an Ethernet port on your server. If using
gigabit fiber Ethernet, use multimode fiber cables with LC connectors.
If using 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. If using 10 Gb fiber Ethernet, use MMF-
850nm cables with LC duplex connectors. See Figure 2.
4Fibre 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 2 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 retention clips. See Figure 2.
9. Turn the system on.
Note: Third-party SAN storage attached to the DD690g must be zoned
before you power on the Data Domain system.

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.
4A system must be operated only from a power
supply input voltage range of 100–240 VAC,
50–60 Hz.
4A Data Domain system is intended to operate
with two working power supplies installed.
4Provide a suitable power source with electrical
overload protection.
4A safe electrical earth connection must be pro-
vided to the power cord. Check the grounding
of the power sources before applying power.
4The 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.
4Permanently 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.
4The power connections must always be
disconnected prior to removal or replacement
of a power supply module from any of the
components in the system.
4A faulty power supply module must be replaced
within 24 hours.
4Do not lift system components by yourself. A
system weighs 51 lbs (23 kg).
4To comply with applicable safety, emission,
and thermal requirements, covers must not
be removed and all bays must be fitted with
plug-in modules.
4Load the payload into the rack beginning at
the bottom to prevent the rack from becoming
top-heavy.
4Do 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 sys-
tem controller top cover must be secured by rotating
the lock 90° to the locked position to prevent users
or operators from accessing the service areas.
Caution: If the system is used in a manner not speci-
fied 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.

DATA DOMAIN DD690g INSTALLATION AND SETUP GUIDE |SIDE 1
ABOUT EXTERNAL STORAGE CONTROLLERS AND PORTS
4The storage array can have single or multiple controllers. Each controller
can have multiple ports.
4One storage controller port is required for each direct-attached connection
to the gateway system.
4A SAN-attached storage controller port used for gateway connectivity
cannot be shared by other SAN-attached hosts that access the storage array.
4Optional 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
4External storage disks should be dedicated to the gateway and not shared
with other hosts.
4Disks should be configured into one or more LUNs and exported to the
gateway.
4A LUN should be configured using as many disks as possible.
4All disks in the LUNs must be identical drives and have identical RAID
configurations.
4The gateway can work with different RAID configurations, but the RAID
configurations that provide the fastest possible 256 KB sequential read
access should be used.
4A volume on the gateway system must have the same types of LUN but
the size can vary.
4The minimum data size for each LUN that a gateway system can access is
400 GiB for initial install. For subsequent LUNs after the initial install, 100
GiB is the minimum.
ABOUT GATEWAY LUN CONFIGURATION RULES
4A gateway system supports one volume composed of one to 16 LUNs.
LUN numbers must start at 0 (zero) but need not be contiguous.
4The maximum LUN number accepted by our gateway systems is 255.
4To 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.
CONNECT EXTERNAL STORAGE
The Data Domain gateway system can be direct-attached to the External
Storage Array as in Figure 4, or Fibre Channel (FC) SAN-attached as in Figure
5. A DD690g 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 2.
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 4 or
Figure 5). Connect the other end as noted in Figure 4 or Figure 5 (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 multi-path failover functionality, consult with the Data
Domain Gateway Compatibility Matrix on the Data Domain Support web site.
FIGURE 4: DIRECT-ATTACHED CONFIGURATION
FIGURE 5: SAN-ATTACHED CONFIGURATION
CREATE LUNS
4On 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.
4On 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.
FIBRE CHANNEL ZONING CONFIGURATION
When attached to a Fibre Channel SAN, every zone for the DD690g gateway
system and external storage arrays must be created in the SAN.
Consult information in the SANs Integration Documentation and
Compatibility Matrices on the Data Domain Support web site. For array
specific zoning configuration details, consult the appropriate third-party array
vendor documentation.
External Storage Conguration
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.
You can configure the system via either the Data Domain Enterprise Manager
(recommended) or the command-line interface (CLI). The Enterprise Manager
is a Web-based, graphical-user interface (GUI) application.
Note: The Data Domain system must have an IP address to use the Enterprise
Manager. The system must be able to communicate with the internet.

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 on
configuring the optional software can be found in the Data Domain Operating
System User Guide (OS 4.6 or earlier) or Administration Guide (OS 4.7).Access
the latest documents at https://my.datadomain.com/US/en/platform.jsp.
Congure 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 need to set up the NFS clients as well to allow access to /backup
on the Data Domain system. This can be done using the following steps:
4Create a mount point (directory) such as /dd/rstr01/backup, and
create an administrative mount point, such as /dd/rstr01/ddvar.
4NFS 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
4Add 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
4To 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.
4For 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
section sets up the CIFS clients to allow access to /backup on the Data
Domain system. You need to set up the CIFS clients as well to allow access to
/backup on the Data Domain system. For additional configuration informa-
tion 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
