OmniEngine disk fragmentation

Hi,

We currently have several OmniEngine servers with just under a terabyte of RAID 5 storage. One of these has recently been flagged up by MS SCOM as having over 99% fragmentation. As a result of this a third party tool (Defraggler) was automatically pushed out to try and resolve this.

Unfortunately this worsened disk I/O performance resulting in dropped packets, so had to be disabled before it could defragment the disk. My questions are as follows:

Should I worry about this and is it a problem?

Has anyone else had issues with fragmentation and if so how have you solved them?

Is there anything I can do to avoid this occurring?

Thanks
