No Bandwidth on disk

Hi,

I have decrypted naz file for my clariion and for disk 0 & 1 for enclosure 0, I see disk utilization to 80%, IOPS to 130-140 IOPS but Bandwidth as 0.

Is this possible and why? If there a problem?

These disks have FLARE on them and are a part of the RAID Group that takes Oracle OLTP. There is no performance impact visible otherwise but just wanted to check the behavior.

Please suggest.

Regards,

Anuj
