I completed, some weeks ago, a Veeam Backup & Replication 9 deployment in which a couple of Dell DR 4100, part of the Dell DR Series Disk Backup and Deduplication Appliances, were used as repository targets.
Initialize a Dell DR4x00 appliance is a very straightforward process, for instance using the Dell iDRAC to launch the virtual console.
Log on to the system as administrator using the password St0r@ge! and set the networking parameters as needed, afterwards the appliance can be managed via web GUI.
A DR appliance provides many networking capabilities that can be adopted based on the hardware in use or the project specifications but, basically, the network interface cards can be configured in the following ways:
- standalone nic
- bonded nic using ALB (Adaptive Load Balancing Mode), no switch configuration, less performance, the total available bandwidth of the bond is equal to the bandwidth of a single physical connection
- bonded nic using LACP (Link Aggregation Control Protocol, 802.3ad), the switches ports have to be configured, more performance with multiple data streams
Applied the appropriate network configuration I’m used to complete the following steps:
- Upgrade the system software
- Configure Active Directory settings
- Configure E-Mail alerts
- Configure Cleaner Schedule
- Create CIFS containers
Now the interesting part related to the integration with Veeam Backup & Replication 9.
To follow the best practices recommended by Dell I suggest to read the Setting Up the Dell™ DR Series System on Veeam Guide, updated in April with Veeam 9.0 screenshots and features and the Dell DR Series System Interoperability Guide.
When creating a repository apply the following best practices:
- Type, select Shared Folder, CIFS (SMB)
- Repository, select the options Decompress backup data blocks before storing and Use per-VM backup files
Veeam backup jobs
When creating backup jobs apply the following best practices:
- Backup Tab, select the Incremental backup mode and the Create active full backups periodically option.
- Storage Tab, select all the Data reduction recommendations, None as Compression level and Local target as Storage Optimization.
Veeam backup copy jobs
When creating backup copy jobs apply the following best practices:
- Storage Tab, select the Data reduction recommendation
- Storage Tab, select None as Compression level
Running the jobs I observed very good throughputs, also because the customer utilizes enterprise-class 10 Gb network switches.
Concluding, despite a DR4x00 appliance is not optimized for the use with Veeam Backup & Replication as an EMC Data Domain, ExaGrid or HPE StoreOnce, I think it can be a valid solution to store Veeam backups and backup copies, providing good throughputs and excellent levels of deduplication and compression.
