Hi! For couple of weeks we notice that theperformance counter Avg. Disk Read / Queue Length on our SQL Servermachine jumps to 40/50. At this time it's almost impossible to workwith the databases and users have to wait for a few minutes when itdrops to normal 1-2. We have a windows server 2003 with sql server 2000running in the vmware ESX server and SAN. I will anyway trydefragmenting from within windows the disk where resides the databasefile but I wanted to know if there could be any other major issues forthis problem. Could this be due to a SAN? Thank you!
