    <description>&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;We have 2 netapp fas2240-2 systems. 1 is located in the main building and the other in a building not far away.&lt;/P&gt;&lt;P&gt;We have 4 thin provisioned nfs luns where our xenapp and pvs servers are hosted. The luns have enough free space and we have around 5 xenapp servers per lun.&lt;/P&gt;&lt;P&gt;When i copy a large file from 1 lun at the main building to a lun in the offsite building i notice a 200+ ms latency on the datastore when i look in vmware performance.&lt;/P&gt;&lt;P&gt;I don't see any latency on the fas system itself and when i run an iometer on 1 of the xenapp hosts im hitting around 45000-50000 IOPS&lt;/P&gt;&lt;P&gt;The luns are thin provisioned and users are complaining for a long time now about performance issues.&lt;/P&gt;&lt;P&gt;Snapmirror is running at 19:00 so i can rule that out and data deduplication only in the weekends at night.&lt;/P&gt;&lt;P&gt;I'm not getting any alerts on the netapp.&lt;/P&gt;&lt;P&gt;Can i rule out the netapp looking at the graphs in the pictures?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;transfer speed&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="3.png" style="width: 426px;"&gt;&lt;img src="https://community.netapp.com/t5/image/serverpage/image-id/4393i983746EF42E00254/image-size/large?v=v2&amp;amp;px=999" role="button" title="3.png" alt="3.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;sending controller&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="2.png" style="width: 999px;"&gt;&lt;img src="https://community.netapp.com/t5/image/serverpage/image-id/4394i94E8E43DFF556176/image-size/large?v=v2&amp;amp;px=999" role="button" title="2.png" alt="2.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;receiving controller&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="5.png" style="width: 999px;"&gt;&lt;img src="https://community.netapp.com/t5/image/serverpage/image-id/4395i7B51197B58FD3CC8/image-size/large?v=v2&amp;amp;px=999" role="button" title="5.png" alt="5.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;veeamone monitor datastore&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="`1.png" style="width: 852px;"&gt;&lt;img src="https://community.netapp.com/t5/image/serverpage/image-id/4396iB9934E19806EFB47/image-size/large?v=v2&amp;amp;px=999" role="button" title="`1.png" alt="`1.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;IOmeter xenapp server&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="4.png" style="width: 776px;"&gt;&lt;img src="https://community.netapp.com/t5/image/serverpage/image-id/4397iA8EB4FF119DEAF08/image-size/large?v=v2&amp;amp;px=999" role="button" title="4.png" alt="4.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks in advanced.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Gr,&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;Michiel&lt;/P&gt;</description>
