100% Disk usage on Windows Server 2008r2

-

hello guys!

have hp proliant g6 server 4 1.5tb sata disks. 2 raid 1 arrays , 2 logical drives 1.5tb.

1 day ago mentioned twith resmon disk usage 100% , i\o speed not more 4mb\s

server hangs..

how can troubleshoot it?

perfmon's process counters include disk io data for each process start see what's going on

you can run process explorer sysinternals uses same perfmon counters bit easier interpret if you're not big on perfmon analysis

normally may able check task manager , processes busy may highest consumers of disk io, not case

if you've changed in anti-virus scanning policies recently, allowing network scanning, exclusions dropped real-time scanning or manual scan being triggered in middle of day, can cause lot of high io

check if have scheduled tasks running around time happening, backup tasks or other jobs can cause high io

finally, if have battery backed write cache module on array, enable it, write performance
