Increasing Capacity

You can also improve performance by increasing the capacity of the DPM server through hardware upgrades:

• Adding disks to the storage pool and reallocating the replicas across the storage pool can help reduce disk queue length.
  
  
• Using striped volumes can increase disk throughput to deal with disk bottlenecks.
  
  
• Adding memory is a relatively inexpensive upgrade that can result in a noticeable improvement in performance if the server frequently experiences low available memory.
  
  
• Adding more processors or upgrading to faster processors can reduce CPU issues.
  
  

Also, consider your data protection requirements: you might need additional DPM servers to balance the workload.
