If using a 100-Gbps Ethernet channel board does not achieve the level of I/O performance you expected, performance might improve by configuring the following parameters in hosts.

When you configure the parameters, the set values are applied to I/O of all devices that are connected to your host. If the host is connected to devices other than an NVMe/TCP channel board, make sure that the new values of the parameters do not affect I/O of other devices before you set the values.

Parameter Value to be set
MTU 9000
SQ flow control
The value to be set differs depending on the OS of your host:
  • For Red Hat Enterprise Linux: Disable
  • For SUSE Linux: Disable
  • For Oracle Enterprise Linux: Disable
