■About NetBackup SAN Client and Fibre Transport
About this guide
This guide describes how to install, configure, and use shared storage with
NetBackup.
NetBackup provides several options that let you share storage among multiple
NetBackup media servers, as follows:
■The AdvancedDisk option allows multiple NetBackup media servers to share
the disk storage that is attached to a NetBackup media server. (Attached means
a file system mount on the storage.)
See “About the AdvancedDisk option”on page 17.
■The OpenStorage option allows multiple NetBackup media servers to share
intelligent disk appliance storage or cloud-based storage.
See “About the NetBackup OpenStorage option”on page 57.
■The SharedDisk option allows multiple NetBackup media servers to share disk
array storage.
See “About SharedDisk support in NetBackup 7.0 and later”on page 133.
■The Shared Storage Option allows multiple NetBackup media servers to share
individual tape drives (standalone drives or drives in a robotic library).
See “About the Shared Storage Option”on page 137.

About NetBackup SAN Client and Fibre Transport
NetBackup also provides a separately licensed option for high-speed data transport.
NetBackup SAN Client and Fibre Transport provide high-performance I/O backup
rates for NetBackup client systems by using a storage area network (SAN) for data
transport.
See the NetBackup SAN Client and Fibre Transport Guide.

Introducing AdvancedDisk
This chapter includes the following topics:
■About the AdvancedDisk option
About the AdvancedDisk option
The NetBackup AdvancedDisk storage option lets you use the disk storage that is
attached to a NetBackup media server. (Attached means a file system mount on
the storage.) NetBackup aggregates the disks into pools of storage you can use for
backups. NetBackup manages the storage as logical entities (disk pools).
Figure 2-1 shows a media server and attached disks.

NetBackup media servers function as
both storage servers and data movers
AdvDiskPool_Gold AdvDiskPool_Silver
The NetBackup AdvancedDisk storage option provides the following benefits:
■Is easy to deploy and use. NetBackup discovers the storage and uses familiar
NetBackup storage units and backup policies to use the storage.
2
Chapter

■Allows multiple file systems to be used in a single storage unit.
■Allows user to increase storage unit capacity by adding disks. Only add the
capacity required, then update the NetBackup disk pools. Logical units of
storage span physical boundaries, so you do not have to create new NetBackup
storage units or change the backup policies.
■Reduces the level of administrator attention. Automatic policies distribute job
load and intelligently manage capacity so that jobs do not fail because of out
of space conditions.

Licensing AdvancedDisk
This chapter includes the following topics:
■About the AdvancedDisk license key
■Licensing AdvancedDisk
About the AdvancedDisk license key
AdvancedDisk is a feature that is licensed separately from base NetBackup. The
Flexible Disk Option license key activates AdvancedDisk.
You may have a single license key that activates both NetBackup and the Flexible
Disk Option. Alternatively, you may have one license key that activates NetBackup
and another key that activates the Flexible Disk Option.
See “Licensing AdvancedDisk”on page 20.
If you remove the Flexible Disk Option license key or if it expires, the following
restrictions apply:
■You cannot create the disk pools or the storage units that reference
AdvancedDisk disk pools.
■NetBackup jobs that attempt to use the disk pools or the storage units that are
based on disk pools fail. The error message indicates that the feature is not
licensed.
NetBackup does not delete the disk pools or the storage units that reference the
disk pools. You can use them again if you enter a valid license key.

Chapter

Licensing AdvancedDisk
No special installation is required for the NetBackup components of AdvancedDisk.
However, you must enter a license key. If you installed the license key when you
installed or upgraded NetBackup, you do not need to perform this procedure.
Enter the license key on the NetBackup master server. The following procedure
describes how to use the NetBackup Administration Console to enter the license
key.
To license AdvancedDisk
1To add a license to a specific server, select File >Change Server and then
select the server.
2In the NetBackup License Keys dialog box, click New.
3In the Add a New License Key dialog box, enter the license key and click Add
or OK.
4Click Close.
5Restart all the NetBackup services and daemons.
