Its been a month long we are working with this performance problem without having a solution yet.
Whenever the write throughput goes around 100 MB/s in any of the LUNs in the same filer,creates huge latency in all other LUNs.
Ontap : 8.0.1 7 mode
My personal intuition is on Nvram, since it was so small for this model. Can anyone help me on which parameters we need to look on in counter objects or even in perfstat.
How come write throughput is related to increase in high write latency?
