Hi, I have a windows 2003 server with a raid 10 array, consisting of 6 disks and 1 spare.
When I copy files to this server over my Gigabit LAN, it takes unusually long. i.e. I can copy files to a RAID5 server with 3 drives and 1 spare running a similar config and on the same LAN segment 3 to 4 times faster than I can copy them to this server.
When I launch the perfmon and monitor Avg. Disk Queue Length , it is 15 on average with a max of 33!
When I monitor % disk time, it is 1600 on average and usually around 3000!
what is going on? my RAID controller shows the raid condition as optimal. What am I missing here?
