Performance Manager is reporting more than 70% utilization on two VMAX FA ports, but the total
IOPS per port is low. What is the likely cause and recommended resolution for the high FA
utilization?
A.
Large block I/O is resulting in high throughput on each port, spread the workload across more
FA directors
B.
SAN switch ports are set to half duplex, change the FA ports to auto-negotiate and reset the
ports
C.
Linux hosts are connected with the SC3 director flag set, check the HBA speed and unset the
SC3 flag
D.
Striped meta devices are being used, convert to concatenated devices and stripe at the host
volume manager
