A customer has recently added four Symmetrix arrays and six CLARiiON arrays to the SAN environment. EMC ControlCenter allocation tasks for the Symmetrix storage now run significantly slower.
Production server access to the Symmetrix and CLARiiON arrays has not changed.
What is a likely cause of the problem?

A.
EMC ControlCenter Performance Manager Archiver has become overloaded

B.
EMC ControlCenter Symmetrix Agent has become overloaded

C.
Servers with unsupported HBA firmware and driver revisions are driving down performance

D.
Traffic from the additional Symmetrix arrays has saturated the SAN
