We are analysing a CX4-240 for a customer which was configured by some other partner.

We have observed that one the LUNs originally RAID 5 has been expanded using Meta LUN through concatenation with another RAID 10 LUN.

We know concatenation would not help with performance. We want to know what impact would a concatenation of RAID 10 LUN with RAID 5 LUN have? Would this also not reduce the performance?
