top command in Sun Fire v880 Server
Hi
I am facing a serious with Sun Fire v880 server..
When I issue the command top this is a brief o/p of it..
As u can see the iowait is 98.6 % and it flucuates around this range..
Due to which users logged in cannot start huge processes..
To brief you this Sun Server is attached to EVA SAN Storage..
