one day suddenly after usage of two years

my vmware exchange server become very slow.

i looked up the cpu usage.

i dont know what is the cause for this sympthom.

i have alot of free space,why my cpu is not balance.

you cannot observe at the process tag what is the cause for that sympthom.

use perfmon to track IO/letency/IO size/throughput/que length an watch CMC for the same stats for your nodes and affected LUNs.  If both nodes are on the same hardware, it sounds like the problem is a software bug.

can't see the graphs, but if you have three other servers that are going fine,  graph all three and see if there is any difference.  If you see something different on the SAN performance than the others then you can narrow it down depending on what you see, but if it all looks the same then its probably a software issue.
