EMC DATA DOMAIN DD880g Istruzioni per il montaggio

The steps for a complete installation and conﬁguration are:

1. Install Hardware

2. Deﬁne the Data Domain system information for your site

4. Perform initial system conﬁguration

5. Conﬁgure the system for data access

6. Conﬁgure optional software

7. Perform optional additional system conﬁguration

Installation and Setup Steps

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.

EMC DATA DOMAIN DD880g INSTALLATION AND SETUP GUIDE |SIDE 1

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

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

Domain Integration Documentation section on the Data Domain Support web

site https://my.datadomain.com/US/en/integration.jsp.
