NetWorker interface

16、s directly with DD Boost; there is no OST component involved, and OST should not be referred to in any NetWorker conversations.Question:What is the Data Domain device type?Answer:The Data Domain device type is the NetWorker configuration option that enables DD Boost capabilities. This is in contrast

17、 to the legacy Advanced File Type Device (AFTD) enabled by the DiskBackup Option and a Virtual Tape Library (VTL) configuration enabled by Autochanger Module licenses. AFTD and VTL configurations will continue to work with NetWorker 7.6 SP1 and higher; however, they do not take advantage of DD Boost

18、.Question:What are the licensing requirements for the DD Boost for NetWorker solution?Answer:For the traditional licensing model, licenses are available that enable the use of the new Data Domain Device type and the DD Boost functionality and are based on the raw disk capacity of the Data Domain sys

19、tem starting at 7 TB. A DD Boost software license is also required to enable DD Boost on the Data Domain system.Consult your EMC Backup Recovery Systems (BRS) sales representative, the EMC Price Book, Direct Express, or Channel Express, or the “EMC Software Price Guide: Backup and Recovery” on Power

20、link for details.Question:What about the entry-level Data Domain systems smaller than 7 TB? What should I sell the customer?Answer:For these opportunities, sell NetWorker Fast Start, which is better suited to an entry-level solution.Question:What software do customers need on the Data Domain system

21、to use DD Boost?Answer:Data Domain Operating System 4.8 or higher is required to leverage DD Boost functionality. Customers with a valid Data Domain maintenance contract can upgrade their Data Domain Operating System at no additional charge, but DD Boost software license must be purchased separately

22、. For additional details regarding Data Domain deduplication storage systems and DD Boost, refer to the “Frequently Asked Questions: EMC Data Domain Deduplication Storage Systems” on Powerlink.Question:Is DD Boost supported on all of the Data Domain system models?Answer:Yes. All models are supported

23、 as long as the Data Domain Operating System 4.8 or higher is installed. This includes the Data Domain Global Deduplication Array.Question:Does NetWorker support Data Domain Archiver?Answer:Yes. DD Archiver requires DD Boost 2.3.1 or higher. NetWorker 7.6 SP2 and higher has been integrated with DD B

24、oost 2.3.1.1, which fully qualifies DD Archiver. Question:Is DD Boost supported in both regular and dedicated NetWorker storage nodes?Answer:Yes.Question:Can a site with a storage node or application host with DD Boost without a Data Domain system back up across the WAN to a remote Data Domain syste

25、m? Answer:No, using DD Boost over the WAN to back up to a remote storage node is not supported. However, using Data Domain Replicator between local and remote Data Domain systems controlled by NetWorker is supported.Question:Is DD Boost also available with the NetWorker client?Answer:No. DD Boost is

26、 integrated with the NetWorker storage node software, NetWorker Module for Microsoft Applications 2.3 and higher., NetWorker Module for Databases and Applications 1.2 and higher, and NetWorker Module for SAP 4.2 and higher. Question:What operating system platforms are supported for the NetWorker sto

27、rage node with DD Boost?Answer:Support for DD Boost is available on the most common platforms, including Microsoft Windows Server 2003 and 2008; Oracle Solaris 9 and 10; IBM AIX (with 7.6.2 and higher); HP-UX 11iv2 and 11iv3 on Itanium (with 7.6.2 and higher); Red Hat Enterprise Linux 4 and 5; and S

28、USE Linux Enterprise Server 9, 10, and 11, with a mixture of 32-bit and 64-bit platforms. Refer to the “EMC NetWorker Compatibility Guide“ on Powerlink to confirm support for a specific operating system, application, and hardware platform.Question:What impact will DD Boost and deduplication processi

29、ng have on server performance? Will customers need to upgrade their server hardware?Answer:DD Boost can actually enhance performance by reducing the amount of data transferred to the Data Domain system, which reduces the I/O load on the server backplane and adapters compared to traditional backup.Qu

30、estion:Will the Data Service Agent (DSA) function on the storage node work with DD Boost?Answer:Yes. The Data Service Agent, which is used to route NDMP backups to disk through the storage node, can be used in conjunction with DD Boost.Question:Can customers migrate an existing NetWorker with Data D

31、omain configuration to the DD Boost-integrated solution?Answer:Yes. A migration part number is available that provides the required licensing to a customer who previously used Data Domain with the DiskBackup or VTL options. The best practice is to redirect new backups to the new Data Domain device t

32、ype configuration and let older backups expire. Another option is to clone existing backups to the new Data Domain device type. Once the cloning operation is complete, the original backups can be deleted. Data Domain VTL users must also consider the connectivity transition from Fibre Channel to Gigabit Ethernet. Question:Will older client software and application modules be able to send backup data through a storage node that uses DD Boost?Answer:Yes. Customers do not nee
