Hello. Now for testing purposes I've two 10Gbits interfaces connected to 10G Switch and to serwer using one 10g NIC. Because MPIO don't changed anything, I had clear reinstaled Windows 2012 R2 Sever and configured only one path to array using computer NIC and one first IP address of Array iSCSI available adresses. I made as simple configuration as possible, but it still works bad. If I configure MPIO it is similar behavior but divided for 4 NIC's. In windows first time I used MD Storage configuration utility to configure MPIO,
It is best to have 2 iSCSI ports per controller configured on your MD3600i. When you have only one iSCSI port per controller configured, you can see slower read & write speed due to all traffic going through a single port on each controller.
In our deployment guide we have the different ways that you can configure your MD3600i if it is a single controller or dual controller. If you have a second nic that you can use in your server and add a second iSCSI connection for each controller you should see improved speeds. Here is the link to our Deployment Guide. https://downloads.dell.com/manuals/common/powervault-md3600i_deployment%20guide_en-us.pdf
Please let us know if you have any other questions.
I read this document, thank you, I checked the solutions contained in it, but it still does not work as it should, maybe the photo I attached something will tell you.The graph clearly shows that the transmission is broken at a certain time …. (it was some iso image....)

Hello NellPola,
How many ISCSI ports are you using per controller? Do you have multipathing configured, if so which policy are you using?
Please let us know if you have any other questions.
