Summary of performance hierarchies
When you are putting together systems, remember that you are doing this to ensure that your data is available and has enough bandwidth/speed to meet the performance requirements. For this reason, invest in quality disk or SSD storage as criteria 1.
Next, configure enough bandwidth on your network to handle the peak amount of traffic allowing you to process the maximum concurrent jobs defined in the service level agreement.
Lastly, configure enough processor cores that are needed for the type of data to be backed up. Do not under populate the amount of DRAM allocated to the compute node. For example, we recommend at least 1GB of DRAM for every TB of storage for running deduplication.
