Configuring the switches - iSCSI, VMware

You configure the switches according to the vendor’s recommendations for iSCSI. These recommendations might include both configuration directives as well as code updates.

You must ensure the following:

  • You have two separate networks for high availability. Make sure that you isolate your iSCSI traffic to separate network segments.
  • You have enabled send and receive hardware flow control end to end.
  • You have disabled priority flow control.
  • If appropriate, you have enabled jumbo frames.
Note

  • Port channels/LACP is not supported on the controller's switch ports. Host-side LACP is not recommended; multipathing provides the same, and in some cases better, benefits.

  • Forward Error Correction (FEC) must be turned off for 25G iSCSI network.
