An Isilon customer is experiencing less than expected performance and poor space utilization with their cluster. They are using the X400 nodes with an N+2d:1n protection policy to host web server log data. Upon further analysis, the customer discovers that the web servers write log files 64KiB in size. The log files are then accessed by an analytics application for reporting purposes. What should be done to increase the write performance of the cluster?

A) Change the protection scheme to a mirroring policy
B) Add S-Series storage nodes to the cluster
C) Add A-Series Performance Accelerator nodes to the cluster
