https://community.hpe.com/t5/windows-server-2003/perfmon-reporting-disk-utilisation-greater-than-100/m-p/4047538#M4468 Hi All,<BR /><BR />Perfmon on Windows Server 2003 reports physical disk utilisation greater than 100% (in some cases the number is as high as 1600%). Performance Object selected is "Physical Disk" and counter is "% Disk Time".<BR /><BR />It would appear that the maximum value should be 100%. Can anyone explain the cause for such high readings?<BR /><BR />p.s. The disk being monitored is a Smart Array single logical disk and to the OS it should appear as a single spindle.<BR /><BR />The HP Proliant Server in question runs standard Proliant Support Pack (including the HP Smart Array driver).<BR /><BR />Thanks,<BR />Saket.<BR /> Wed, 01 Aug 2007 01:33:34 GMT SAKET_5 2007-08-01T01:33:34Z https://community.hpe.com/t5/windows-server-2003/perfmon-reporting-disk-utilisation-greater-than-100/m-p/4047538#M4468 Hi All,<BR /><BR />Perfmon on Windows Server 2003 reports physical disk utilisation greater than 100% (in some cases the number is as high as 1600%).
