This Veeam Ready Test was performed with storage having a configuration that includes SSD/Flash. Additionally, this test has been performed by utilizing dsmISI load-balancing solution to optimize performance across multiple PowerScale nodes and mitigate some of the limitations of OneFS filesystem.

As such, this classification only applies to similar configurations in which one or more SSD drives are used and load-balancing implemented.  The use of non-SSD drives may negatively impact performance. The lack of load-balancing solution implementation may negatively impact performance and scalability.

Product Details

Model number: A200
Storage Category: Scale-out NAS
Drive quantity, size, type: 15 – 1TB SATA HDD, 2 – 400GB SSD (per node)
Storage configuration: Default +2d:1n protection was used (OneFS erasure coding protection level that protects against two drive failures or one node failure)
Firmware version: OneFS 9.0
Connection protocol and speed: NFS, 10 GbE
Additional support: All models and configurations of PowerScale / Isilon Gen6 with specifications equivalent or greater than the above

General product family overview: 

PowerScale is a scale-out NAS that supports 3 to 252 nodes in a cluster.  Files are automatically distributed, balanced, and protected across the cluster and all files are accessible from all nodes.

Veeam Testing Configuration

The following settings were used by the vendor to meet Veeam Ready testing requirements and should not be considered best practices. Additional changes or settings may be needed to meet the storage efficiency or performance needs for each environment. For each setting, reference links are provided for further clarification.

Veeam Build Number: P20210324

Job Settings:

Deduplication:  Enabled (Default)
Compression:  Optimal (Default)
Storage Optimization:  Local Target (Default)

Repository Settings:

Repository Type:  Linux
Align backup file blocks:  Enabled (Default)
Decompress before storing:      Disabled (Default)
Per-VM Backup Files:  Disabled

Vendor recommended configuration

Additional Considerations:

Dell EMC PowerScale has a default maximum file size limitation of 4TiB.  OneFS 8.2.2 or later has the option to increase the maximum file size limitation to 16TiB. By using the dsmISI software load balancer implemented during this test these limitations are alleviated, including file size limitations, block cloning support for fast synthetic processing and space savings.
