HP Store Once Backup System 4900 Installation and Configuration Guide

• Adequate protection from dust, pollution, and particulate contamination

• Adequate acoustic insulation for operating the system.

Backup strategy

The backup strategy impacts networking and Fibre Channel decisions.

• To back up to StoreOnce Catalyst stores, Ethernet connectivity is required. Backup jobs use

the same network paths to/from the appliance. Catalyst copy jobs always use Ethernet

connectivity between StoreOnce appliances. If using Symantec NetBackup or Backup Exec,

the HP StoreOnce Catalyst OST plugin is required. It must be installed on each Media Server

required to write data to the StoreOnce Catalyst stores. The latest version of the OST plugin

is recommended (currently 3.0), OST Plugin 2.1 is a minimum requirement for Backup Exec.

NOTE: Catalyst over Fibre Channel is supported with StoreOnce software version 3.11.0

and later. This feature is not automatically enabled; please consult your HP Sales Representative

for more information. Systems running StoreOnce software version 3.11.0 or later require the

HP StoreOnce Catalyst OST 3.0 plugin when using Symantec NetBackup.

• To use Virtual Tape, iSCSI over Ethernet or Fibre Channel connectivity is required. StoreOnce

VTL replication always uses the Ethernet connectivity.

NOTE: The HP Data Protector DFMF (Distributed File Media Format) for Data Protector's

virtual full backups is not supported for use with the StoreOnce Backup System. This format is

very inefficient with deduplication devices. For further details see HP StoreOnce Backup system

Concepts and Configuration guidelines.

• To back up to a NAS target, Ethernet connectivity is required. Backup and replication jobs

use the same network paths to/from the appliance.

• You can use a combination of VTL, NAS shares and StoreOnce Catalyst stores.

Do you intend to create virtual tape libraries as backup targets (iSCSI and/or FC)? ..........

If required, is iSCSI installed on the host?..........................................................................

Which backup application are you using? ..........................................................................

Do you intend to create NAS shares as backup targets (Ethernet only)?...................................

Which backup application are you using? ..........................................................................

If creating CIFS shares, will you be using Active Domain (AD) authorization? ...........................

NOTE: If the Backup system is part of an AD domain, it is possible to add external users and

groups on the same domain as StoreOnce users with access to all StoreOnce features.
