I have a double which is needs to be solved because it is very important for my Storage Area Network. Has anyone heard about the disk write caching or something similar words? The thing is how can I verify this if it is enabled? The LUN also called as Logic Unit Number is set to enable on SAN. But I am feeling some bad performance issues. The issue like Read = 349MB/s, Write = 90MB/s. Do you have any clue about this thing? I didn’t get any result yet. So what do you think about it?
