% Disk Time

Hello! I have an array in my SAN that have high % disk time (avg 70 or so), but booth the avg. disk read queue length and the avg. disk write queue length are well below 1. What does this mean?
% disk time has no relevence in servers (with SCSI/SAS/FC drives)
disregard it i know some people say it should below xx
but they do not know what they are talking about
their experience is based on IDE/SATA drives
Thank you
