Thanks for the suggestion. I tried both of these with no difference in performance.I have tried several other Dell hosts with Idrac Enterprise and getting the same results. I also tried a new Dell T130 with Idrac express and was getting over 700 MB/s. Any other users had this issues with Idrac Enterprise??
