Executive summary This paper provides guideline about how to set up the Dell DR Series System as a backup to disk target for RMAN® over CIFS/Rapid CIFS and NFS/Rapid NFS. For additional information, see the DR Series system documentation and other data management application best practices whitepapers for your specific DR Series system at: http://www.dell.
1 Installing and configuring the DR Series system 1. Rack and cable the DR Series system, and power it on. Initialize the DR Series system. In the Dell DR Series System Administrator Guide, refer to the following topics: “iDRAC Connection”, “Logging in and Initializing the DR Series System and “Accessing IDRAC6/Idrac7 Using RACADM” for more information. 2. Log on to iDRAC using the default address 192.168.0.
4. After the virtual console is open, log on to the system as user administrator with the password St0r@ge! (The “0” in the password is the numeral zero). 5. Set the user-defined networking preferences. 6. View the summary of preferences and confirm that it is correct.
. Log on to DR Series system administrator console using the IP address you just provided for the DR Series system with the username administrator and password St0r@ge! (The “0” in the password is the numeral zero.). 8. Join the DR Series system to Active Directory. Note: If you do not want to add the DR Series system to Active Directory, please see the DR Series System Owner’s Manual for guest logon instructions. a. 7 Under System Configuration in the left navigation area, click Active Directory.
b. Enter your Active Directory credentials. 9. Create and mount the container by selecting Storage > Containers in the left navigation area, and then clicking Create at the top of the page.
10. Enter a Container Name, click Next. 11. Select the NAS (NFS, CIFS) option and click Next. 12. Enable the access protocols as needed, and then click Next.
13. For NFS, provide the client access information and click Next. 14. For CIFS, provide the client access control information and click Next.
Note: For improved security, Dell recommends adding IP addresses for the Backup console (RMAN). Not all environments will have all components. 15. Click Create a New Container, and then confirm that the container is added. 16. Select the Container that was just created and click Edit. Note the container share/export path, which you will use later to target the DR Series system.
2 Configuring a backup job on RMAN over a CIFS target 2.1 Oracle settings for Windows RMAN Online Backup There are two options for RMAN to authenticate to the DR Series system through CIFS.
CONFIGURE CHANNEL DEVICE TYPE DISK MAXOPENFILES 1 FORMAT ‘\\/ora_df%t_s%s_s%p’; 2. Configure RMAN to back up the control file after each backup. 2.4 RMAN backup of full database Backup Oracle Database using RMAN with BACKUP INCRMENTAL LEVEL 0 DATABASE FILESPERSET 1; 2.
2.6 Backup with different options BACKUP ARCHIVELOG ALL; BACKUP DATABASE PLUS ARCHIVELOG; 2.7 RMAN restore of Oracle database from DR Series system The following screen shot shows the restore process of Oracle Database through RMAN from DR Series system images.

The default location of the archive log restore will be where they are created.
3 Replicating Oracle RMAN database images First, you need to create containers on the source and target DR Series systems and then configure replication between those source and target DR containers. Both of the DR Series systems should be on the same version. Refer to the Dell DR Series System Administrator’s Guide for information about configuring cascaded replication.

4 Configuring a backup job on RMAN over an NFS target 4.1 Create a storage device for NFS For NFS backup using RMAN, a target folder needs to be created as an NFS share directory. This is the location to which backup objects will be written. (This is not required while adding CIFS share.) 1. Mount the DR Series System NFS share onto the NFS share directory which backup objects will be written in the RMAN environment. 2.
5 Creating a storage device for Rapid CIFS 5.1 About the Rapid CIFS plugin Rapid CIFS enables write operation acceleration on clients that use CIFS file system protocols. These accelerators allow for better coordination and integration between DR Series systems backup, restore, and optimized duplication operations with Data Management Applications (DMAs) such as CommVault, EMC Networker, and Tivoli Storage Manager.
6 Creating a storage device for Rapid NFS 6.1 About the Rapid NFS plugin Rapid NFS enables write operation acceleration on clients that use NFS file system protocols. These accelerators allow for better coordination and integration between DR Series systems backup, restore, and optimized duplication operations with Data Management Applications (DMAs) such as CommVault, EMC Networker, and Tivoli Storage Manager. For the current list of supported DMAs, see the Dell DR Series System Interoperability Guide.
7 General best practices for RMAN backups to the DR Series system The Dell DR Series system supports RMAN backups over both CIFS and NFS protocols. With client side optimization drivers like Rapid CIFS and Rapid NFS backups become faster and more efficient. Several options exist with RMAN that every DBA should be aware of. These effect how RMAN behaves when performing its backup duties.
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/home/orabase/product/11.2.0/db_1/dbs/snapcf_apple.
8 Setting up the DR Series system cleaner Performing scheduled disk space reclamation operations are recommended as a method for recovering disk space from system containers in which files were deleted as a result of deduplication. The cleaner runs during idle time. If your workflow does not have a sufficient amount of idle time on a daily basis, then you should consider scheduling the cleaner to force it to run during a scheduled time.
9 Monitoring deduplication, compression, and performance After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the DR Series system dashboard. This information is valuable in understanding the benefits of the DR Series system. Note: Deduplication ratios increase over time. It is not uncommon to see a 2-4x reduction (25-50% total savings) on the initial backup. As additional full backup jobs are completed, the ratios will increase.
