Performance issues with MD3200i
My Dell MD3200I has performance issues. Server was recently purchased to server a purpose as a backup storage.
Transfer rate is in the mid of 20MB/s at all times and jumps upto 50MB/s and to 0 continuously. There are no errors on the array. I was hoping anyone had experience with the appliance that could shed some light where to start the troubleshooting.
Thank you

Hello AlexKW,
How many iSCSI connections to each controller on your MD3200i are configured? What type iSCSI adapters are you using in your server? Is your MD3200i direct connected to the server or is it going through a switch? Here is a link to our deployment guide and I would confirm that your setup is using best practices. https://downloads.dell.com/manuals/common/powervault-md3200i_deployment%20guide_en-us.pdf
Please let us know if you have any other questions.

Hello AlexKW,
Are you using Round Robin for your multipathing? Are your host in a separate vlan from your MD3200i traffic? How many virtual disks are owned by each controller?
Please let us know if you have any other questions.
